−
For the purposes of faster dissemination of updates to the Live image via something like rsync you can mount an image file.
+
Refer to: [[Live_GIS_Virtual_Machine]].
−
Make sure you turn off the virtual machine before you attempt to mount it, and that you unmount it before you attempt to run the vm again.

= Build the Live DVD ISO image =
−
This method assumes you have vmware server installed, the key is that the vmware-mount script is on your system somewhere.
 
−
This instructions use /space/virtual as the vmware installation folder and /space/virtual/machines as the location of the disk images.

(''Linux host only'')
 
  
−
If you have KVM installed use "<tt>qemu-kvm</tt>" or "<tt>kvm</tt>" instead of <tt>qemu</tt> on the command line. The usage is the same. It will be a ''lot'' faster. To run KVM you will have to have a newer CPU which supports hardware virtualization, a recent kernel, and have virtualization enabled in the BIOS. You'll want to make sure that the kvm kernel modules are loaded, /dev/kvm exists, and your user account belongs to the 'kvm' group. Older releases of QEMU may be partially accelerated by installing the KQEMU plugin. Without any sort of acceleration it will still run, but very very slowly.
+
This section describes the new method for building OSGeoLive as described in [https://help.ubuntu.com/community/LiveCDCustomization official ubuntu wiki]. This section is self-contained and there is no need to perform any of the procedures described above.
  
−
=== Running live from a bootable ISO file ===
+
All you need is a running Ubuntu/Xubuntu/Kubuntu/Lubuntu installation (even within a virtual machine as long as it has ~20GB free disk space). All needed to be done are the following steps under a "user" account:
−
Specify that at least 512mb of RAM should be used. In this example 720mb has been requested which is a bit more comfortable and the ISO will be run live.
 
  
−
  qemu -m 720 -cdrom osgeo_live.iso
+
* Bootstrap the host operating system. If you use the system to build more than once, then this must be done only for the first build
−
or
+
  host$ cd /tmp
−
  kvm -m 720 -cdrom osgeo_live.iso
+
host$ wget https://github.com/OSGeo/OSGeoLive/raw/master/bin/bootstrap.sh
 +
host$ chmod a+x bootstrap.sh
 +
  host$ sudo ./bootstrap.sh
 +
This will install Git and the install scripts, and create a link to them from your home directory.
  
−
For me the mouse didn't work (it was just stuck in the middle of the screen). The fix was to set this environment variable before running <tt>kvm</tt>:
+
* Set the Version Number and Changes
−
export SDL_VIDEO_X11_DGAMOUSE=0
+
  Update https://github.com/OSGeo/OSGeoLive/blob/master/VERSION.txt with the current version number.
  
−
* There is a good HowTo here: http://wiki.centos.org/HowTos/KVM
+
  Update https://github.com/OSGeo/OSGeoLive/blob/master/CHANGES.txt with changes since the last release.
 +
This list can be a summary of the [https://github.com/OSGeo/OSGeoLive/commits/master revision log] between releases
 +
Commit the changes to Git through a Pull Request right before a release build.
  
−
=== Install to a persistent VM ===
+
* Execute the build script:
−
Create a permanent 5gb VM to work in:
+
  host$ cd ~/gisvm/bin
−
  qemu-img create -f qcow2 livedisc.img 6G
+
  host$ sudo ./build_chroot.sh amd64 release master OSGeo 2>&1 | tee /var/log/osgeolive/chroot-build.log
−
or
 
−
  kvm-img create -f qcow2 livedisc.img 6G
 
  
−
Next start kvm with the ISO as the virtual CD drive and the VM image file as the the first hard drive (hd''a''). The "-boot d" option tells it to try to boot from the virtual CD drive first.
+
* Compress the logs:
−
: (from now on I'll just give the <tt>kvm</tt> version of the commands)
+
  host$ cd ~/livecdtmp
−
  kvm -hda livedisc.img -cdrom osgeo_live.iso -m 720 -boot d
+
  host$ tar czf version-log.tar.gz -C /var/log osgeolive
  
−
From within the VM, run the installer either from the boot menu or from the icon on the desktop of the Live OS. You should see the empty 6gb partition you created a few minutes ago. You can decide yourself if you want a swap space partition or not. I didn't, will adjust the -m size on the command line if I need more.
+
* After the completion of the above script the new iso file is located in ~/livecdtmp along with the build logs. In case you wish to rerun the build process, do not remove or move the lubuntu official iso located in this folder to skip downloading it again.
  
−
After it has installed you can restart qemu/kvm but without the -cdrom this time:
+
* It is required to reboot your host machine after build is completed
−
kvm -hda livedisc.img -m 720
 
  
−
At this time it might be a good idea to zip up a copy of the VM. If you want to start fresh later you can just delete the working image and replace it with the fresh version you zipped earlier.
+
* Once the ISO is complete copy it out to a server (a local server is fastest)
−
 
+
  scp ~/livecdtmp/osgeolive-mini-8.0.iso user@server.org:destination/path/
−
=== Getting in via ssh ===
+
  scp ~/livecdtmp/osgeolive-mini-8.0-log.tar.gz user@server.org:destination/path/
−
(ssh'ing out is trivial)

''Instructions on how to ssh into the QEMU/KVM VM can be found in the [http://wiki.laptop.org/go/Emulating_the_XO/Help_and_tips#SSH_into_qemu OLPC wiki].''
 
−
 
 
−
* Within the VM install the openssh-server package. This should generate RSA keys.
 
−
 
 
−
* Start the VM on the host with the command line option:
 
−
kvm [...] -redir 'tcp:2222::22'
 
−
 
 
−
* This will allow you to ssh to port 2222 on the host machine to get into the VM:
 
−
ssh -p 2222 user@127.0.0.1
 
−
 
 
−
* Add the "-nographic" command line option when you start up kvm if you want to start it headless.
 
−
* Add "-X" as a ssh command line option if you want to be able to tunnel X-Window apps from the VM.
 
−
 
 
−
== Mount the ISO as a readonly filesystem ==
 
−
:Not recommeded, it's preferred to get the image right to start, you will not be able to edit files inside the squashfs this way.
 
−
  mkdir test_iso
 
−
  mount -t iso9660 -o loop,ro livedvd.iso ./test_iso
 
−
 
 
−
If you want to do this without su rights, use the FuseISO package.
 
−
fuseiso -p livedvd.iso ./test_iso.$$
 
−
 
 
−
Unmount the FuseISO filesystem with:
 
−
fusermount -u ./test_iso.$$
 
−
=== Mount the ISO for changes ===
 
−
If you're on ubuntu to can edit and remaster and ISO with ISOMaster
 
−
sudo apt-get install isomaster
 
−
 
 
−
On Windows try Daemon tools and related software.

= Creating a fresh Virtual Machine =
 
−
== System Requirements ==
 
−
* RAM: You can only just get away with 1 Gig. 2 Gig is what you will require to avoid slowdowns due to memory swapping.
 
−
* About 10 Gig of spare hard disk for building a Virtual Machine.(20GB if you intend to build an ISO as well.)
 
−
* '''Recommended:''' An Ubuntu based linux distribution. We built this Live DVD process using an Ubuntu based system, and some of the steps assume the hosting operating system is Ubuntu, however you should be able to achieve all the steps (some slightly modified) from Windows.
 
−
 
 
−
== Selecting a Virtual Machine ==
 
−
 
 
−
The arramagong Live DVD can be built using a range of virtual machines. Here we explain our preferences and reasons:
 
−
 
 
−
; VirtualBox
 
−
: VirtualBox is provided as Open Source and can be downloaded onto an Ubuntu based system using apt-get which is great.
 
−
VirtualBox is our current recommendation, as it has been the more stable of our implementations so far.
 
−
 
 
−
Unfortunately, we haven't worked out how to convert from VirtualBox back to VMware images yet, and so far VMware Player software is more widely deployed than VirtualBox. So for the moment, we plan to build vmware images then convert to virtual box (rather than the other way around).
 
−
 
 
−
; VMware Server
 
−
: VMware server provides a browser based interface to the virtual machine which can be accessed over the internet. (This is a good way to let others view your virtual machine without them having to download the large Virtual Machine)
 
−
VMware Server also provides compression tools which we use at the end of the build process. (These are not provided by VMWare Player)
 
−
Unfortunately, there are instability issues with VMWare 2.0.2 + Ubuntu 9.04 / 9.10 (as a host), which means we have been unable to use this combination to build Arramagong 3.0. (The compression tools still seem to work).
 
−
The vmware images that are created can be used with VMWare Server, VMWare Player and relatively easily can be converted to VirtualBox format. (We haven't worked out how to convert from VirtualBox back to VMware images yet).
 
−
 
 
−
; VMware Player
 
−
: VMware Player provides a desktop application which runs a Virtual Machine, and can be used to create a vmware image. It doesn't provide the image compression utilities. (Can we download these from somewhere?)
 
−
 
 
−
; QEMU with KVM acceleration
 
−
: Very well supported by newer Linux kernels (KVM is the kernel developer's darling right now). Fully open source and installs from standard Ubuntu packages. Very easy to run. Only runs with Linux as the host, but can run any OS as the guest. See instructions elsewhere on this page. The kvm-img virtual-disk image creating program can create in a number of different VM formats by changing the -f parameter. (''used by HB'')
 
−
 
 
−
; Click2Try
 
−
: http:/click2try.com provide a web site for trialing virtual machines. They built an arramagong 2.0 release for FOSS4G 2009, and as of Feb 2009, have been working on setting an environment set up for 3.0. This should provide a good development environment once set up, but we will need to have a parallel VM development as well as I don't think they will not be building a VM for us.

−
== Install VirtualBox ==
 
−
 
 
−
 
 
−
== Install VMWare Server ==
 
−
<strike>
 
−
'''Note: During the building of Arramagong 3.0, we have found VMWare Server installed on Ubuntu 9.04 and 9.10 to be unstable to the point of being unusable.
 
−
 
 
−
We have successfully installed used a CentOS 5.3 host + VMware Server 2.0.2 (Make sure you don't accept any security updates as this introduces the bug which makes VMWare unstable). We suspect that Ubuntu 8.04 (LTS) + VMware should work as it is supposed to be supported, but we haven't verified this yet.
 
−
 
 
−
Alternatively, you can build images in VMWare Player.'''
 
−
 
 
−
You will need [http://www.vmware.com/products/server/ VMWare server] which provides all the tools for configuring a VM, setting the disk size, compressing the image etc. VirtualBox doesn't seem to have the compression scripts required, and it doesn't seem to have a way to copy your image to VMWare.
 
−
 
 
−
If you are installing on linux, the installer will ask a series of questions. Answer the default for everything, except the default administrator. For this, you need to enter in your <user_id> for the local computer you are installing on.
 
−
 
 
−
Once running, you should be able to access vmware server at:
 
−
https://127.0.0.1:8333
 
−
 
 
−
As explained [http://planetvm.net/blog/?p=1087 here], firefox has issues connecting to VM until you fix it by doing the following:
 
−
* Go to the url: about:config
 
−
* Update the following:
 
−
** security.enable.ssl2 from '''false''' to '''true'''

== Create an Xubuntu Virtual Machine for VirtualBox ==
 
−
If you already have an Xubuntu (or similar) Virtual Machine, you can skip this step.
 
−
 
 
−
Otherwise, run VirtualBox, and create an image.
 
−
 
 
−
Download the latest desktop i386 [http://www.xubuntu.org/ Xubuntu ISO]. Copy to the Virtual Machine directory:
 
−
mv xubuntu-10.04-desktop-i386.iso "~/.VirtualBox"
 
−
 
 
−
* Run VirtualBox
 
−
* Select Name=osgeolive
 
−
* Operating System=Linux
 
−
* Version=Ubuntu
 
−
* Base Memory Size (RAM) = 512 MB
 
−
* Create a new hard disk
 
−
* Select "Dynamically expanding storage"
 
−
* Hard Disk Size = 20 GB
 
−
To boot from the ISO:
 
−
* Select Settings->Storage->CD/DVD Device-> Add -> select the xubuntu ISO
 
−
* Select the Xubuntu ISO
 
−
To allow ssh access to the the VM:
 
−
* Select Settings -> Network -> Adapter 2 -> Enable Network Adapter -> Attached to: Bridged Adapter, Name: eth0
 
−
 
 
−
The following settings were required with an Ubuntu 9.10 guest operating system, but don't seem to be required for Ubuntu 10.04:
 
−
 
 
−
<strike>
 
−
If the display is not rendering for the VM, try:
 
−
* in Settings -> System -> Motherboard -> Extended Features:, untick "Enable ACPI"
 
−
* in Settings -> Display -> Video, set Video Memory = 64 MB.
 
−
</strike>
 
−
 
 
−
Run the Virtual Machine, which will boot from the Xubuntu CD. Select to install Xubuntu, using defaults, plus:
 
−
* Language: English (default)
 
−
* Location: (FOSS4G City)
 
−
* Prepare disk space: Erase and use the entire disk (default)
 
−
* Keyboard layout: USA (default)
 
−
* Name: user
 
−
* Login name: user
 
−
* Password: user
 
−
* Computer name: osgeolive
 
−
* [x] Log in automatically
 
−
 
 
−
After installing xubuntu, disconnect the ISO image from the CD and reference the physical drive instead.
 
−
* select Settings->Storage->CD/DVD Device: Empty
 
−
 
 
−
The save the virtual machine for use later on:
 
−
* select File->Export Appliance ... -> accept defaults
 
−
 
 
−
== Create an Xubuntu Virtual Machine for VMWare ==
 
−
<strike>If you already have an Xubuntu (or similar) Virtual Machine, you can skip this step.
 
−
 
 
−
Otherwise, run VMWare Server, and create an image.
 
−
 
 
−
Download the latest [http://www.xubuntu.org/ Xubuntu ISO]. Copy to the Virtual Machine directory:
 
−
 
 
−
wget http://mirror.internode.on.net/pub/ubuntu/xubuntu/9.04/release/xubuntu-9.04-desktop-i386.iso
 
−
  mv xubuntu-9.04-desktop-i386.iso "/var/lib/vmware/Virtual Machines/"
 
−
 
 
−
Run vmware, which opens up a browser based User Interface.
 
−
vmware
 
−
 
 
−
Create a new Virtual Machine with:
 
−
* Virtual Machine name = "osgeolive"
 
−
* RAM = 512 Gig (we might want to experiment with less)
 
−
* Hard Disk = 20 Gig (If you plan to make an ISO you will need the space, just the VM install will fit in 8GB with little extra room, but it is a pain to increase later, and can't be done from VMWare Player)
 
−
* Mount the XUbuntu ISO image for the disk drive
 
−
 
 
−
For VirtualBox, select the virtual machine -> Settings
 
−
The following will allow ssh into the virtual machine (for easy building):
 
−
* Network -> Adapter 2 -> Enable Network Adapter -> Attached to: Bridged Adapter -> Name: eth0 (usually)
 
−
* Display -> Video Memory:64K, Enable 3D acceleration.
 
−
 
 
−
Run the Virtual Machine, which will boot from the Xubuntu CD. Select to install Xubuntu, using defaults, plus:
 
−
; What is your name?
 
−
: user
 
−
; What is your password?
 
−
: user
 
−
; What is the name of your computer?
 
−
: arramagong
 
−
; [x] Log in automatically
 
−
 
 
−
After installing xubuntu, in the VMWare Summary tab, select the change the CD drive from pointing to the xubuntu iso to point to the actual hard drive.

'''Side note:''' [https://help.ubuntu.com/community/JeOSVMBuilder vmbuilder] is reported to be a good way to create an Ubuntu image. I haven't tried it, and haven't worked out if it can create the smaller Xubuntu image. (Please update this wiki if you try it). Note: This method requires you to be running the same or newer version of Ubuntu than you want to make an image for.

== Backup base Virtual Machine ==
 
−
You should now have a XUbuntu Virtual Machine image in /var/lib/vmware/Virtual Machines/ . It would be a good idea to save a copy of this machine somewhere, so you can use it again.

== Click2Try: Add user=user ==
+
== How to do development / debugging with the current build method ==
−
The base Xubuntu image only has a root user. The following needs to be done to add user="user", pass="user"
 
  
−
* In order to allow a low security password, Update /etc/common-password/common-password
+
We have created a debug build process so that projects can now easily create their own iso, including parts of the OSGeoLive (eg only one project) in order to test if the installer scripts work well under this new build method.
 +
Here are the steps to debug/test your application:
  
−
Once we place above file then we can create user "user" and set password.
+
===One time steps===
  
−
Here are the steps which we have followed.
+
You will need to create a pure Lubuntu Virtual Machine setup:
  
 +
* Download lubuntu-22.04-desktop-amd64.iso from [http://cdimage.ubuntu.com/lubuntu/releases/22.04/release/lubuntu-22.04-desktop-amd64.iso lubuntu web site].
 +
* Download and install VirtualBox.
 +
* Create a fresh VM installation of Lubuntu. You will need to create a virtual disk drive with at least 25 GB of space and allocate 768MB of RAM to the VM. During installation set the username to "user" and hostname to "osgeolive". DO NOT install system updates during lubuntu installation or after the installation is done. At this moment we work with the default kernel included in lubuntu.
 +
* After the VM is done, login as "user" and open a terminal.
 +
* Bootstrap the VM:
 +
osgeolive$ cd /tmp
 +
osgeolive$ wget https://github.com/OSGeo/OSGeoLive/raw/master/bin/bootstrap.sh
 +
osgeolive$ chmod a+x bootstrap.sh
 +
osgeolive$ sudo ./bootstrap.sh
  
−
#useradd user
+
This will install Git, the install scripts, and create a link to them from your home directory.
  
−
#passwd user [Set the password as "user"]
+
===Steps to create the build (repeat as much as needed)===
  
−
#usermod -u 499 user
+
* Make changes to your project's installation script and commit to Git.
  
−
# su user
+
* Update the git code:
 +
osgeolive$ cd ~/gisvm
 +
osgeolive$ git pull origin master
  
−
Above command will create directory once we login using user "user".
+
* Open file inchroot.sh with an editor and comment out all scripts you do not need for your test.
 +
osgeolive$ cd ~/gisvm/bin
 +
osgeolive$ vi inchroot.sh
  
−
About ubuntu release version, yes for gisvm which we build  earlier stage was ubuntu904 as per requirement.
+
* Always leave un-commented the following scripts: setup.sh, install_services.sh, install_mysql.sh, install_java.sh, install_apache2.sh, install_tomcat6.sh, install_desktop.sh and setdown.sh.  
  
−
Please mail us if you find issues.
+
* Save your changes and execute the build:
 +
osgeolive$ cd ~/gisvm/bin
 +
osgeolive$ sudo ./build_chroot.sh amd64 2>&1 | tee /var/log/osgeolive/chroot-build.log
  
−
== Click2Try: Create an Arramagong base image ==

* Make the image external: Highlight the VM in the application manager, shut the VM down (make sure you save the session), click on the sharing tab,
 
−
click on the public access button.  This feature actually has a second benefit.  It keeps the VM running even when you leave the VM from the viewer.  That way, when you log back into click2try you can access the VM much quicker.

Convert to vmdk format (more widely compatible):
−
Take a copy of the Virtual Machine, as you don't want VMWare tools installed on the ISO image (in the next step).

−
VMWare tools allow cut and paste from the host operating system to a VMWare virtual machine, and also speeds up graphic rendering on VMWare.
 
−
 
 
−
In the VMWare browser control panel, select the virtual machine, then "Summary" tab. Turn on the virtual machine, then select "Install VMWare tools". This mounts the vmware-tools scripts in the arramagong virtual machine, so that it can be installed. Which you can do using the following commands:
 
−
 
 
−
arramagong$ cd /tmp
 
−
arramagong$ tar -zxf /media/cdrom0/VMwareTools-7.7.5-156745.tar.gz

Latest revision as of 09:02, 26 June 2022

Getting started

The first thing you will have to do is check-out the latest build scripts using either one of these two Git servers: 

git clone https://git.osgeo.org/gitea/osgeolive/OSGeoLive.git

git clone https://github.com/OSGeo/OSGeoLive.git
  • see here for more details.

How to add your project to OSGeo Live

Creating a fresh Virtual Machine to use as a build host (Optional)

Refer to: Live_GIS_Virtual_Machine.

Build the Live DVD ISO image

Build ISO

This section describes the new method for building OSGeoLive as described in official ubuntu wiki. This section is self-contained and there is no need to perform any of the procedures described above.

All you need is a running Ubuntu/Xubuntu/Kubuntu/Lubuntu installation (even within a virtual machine as long as it has ~20GB free disk space). All needed to be done are the following steps under a "user" account:

  • Bootstrap the host operating system. If you use the system to build more than once, then this must be done only for the first build
host$ cd /tmp
host$ wget https://github.com/OSGeo/OSGeoLive/raw/master/bin/bootstrap.sh
host$ chmod a+x bootstrap.sh
host$ sudo ./bootstrap.sh

This will install Git and the install scripts, and create a link to them from your home directory.

  • Set the Version Number and Changes
 Update https://github.com/OSGeo/OSGeoLive/blob/master/VERSION.txt with the current version number.

 Update https://github.com/OSGeo/OSGeoLive/blob/master/CHANGES.txt with changes since the last release.

This list can be a summary of the revision log between releases Commit the changes to Git through a Pull Request right before a release build.

  • Execute the build script:
host$ cd ~/gisvm/bin
host$ sudo ./build_chroot.sh amd64 release master OSGeo 2>&1 | tee /var/log/osgeolive/chroot-build.log
  • Compress the logs:
host$ cd ~/livecdtmp
host$ tar czf version-log.tar.gz -C /var/log osgeolive
  • After the completion of the above script the new iso file is located in ~/livecdtmp along with the build logs. In case you wish to rerun the build process, do not remove or move the lubuntu official iso located in this folder to skip downloading it again.
  • It is required to reboot your host machine after build is completed
  • Once the ISO is complete copy it out to a server (a local server is fastest)
scp ~/livecdtmp/osgeolive-mini-8.0.iso user@server.org:destination/path/
scp ~/livecdtmp/osgeolive-mini-8.0-log.tar.gz user@server.org:destination/path/
  • And/OR wget or scp the file to the upload.osgeo.org server (Note wget is much faster if you have a good webserver to host from)

Build Full ISO from Mini ISO

Any mini iso file resulting from the procedure below can be turned into full iso, which is identical but adds the Windows and Mac software installers. Note that the resulting file may be bigger than a DVD. In that case the list of included applications in the load_mac_installers.sh need to be edited to exclude additional applications.

The standard current rules used to pick applications:

  • Desktop Applications
  • OSGeo projects and Incubated projects
sudo ./build_full_iso.sh /full/path/to/osgeo-live-mini-8.0.iso 2>&1 | tee ~/build_full_iso.log

How to do development / debugging with the current build method

We have created a debug build process so that projects can now easily create their own iso, including parts of the OSGeoLive (eg only one project) in order to test if the installer scripts work well under this new build method. Here are the steps to debug/test your application:

One time steps

You will need to create a pure Lubuntu Virtual Machine setup:

  • Download lubuntu-22.04-desktop-amd64.iso from lubuntu web site.
  • Download and install VirtualBox.
  • Create a fresh VM installation of Lubuntu. You will need to create a virtual disk drive with at least 25 GB of space and allocate 768MB of RAM to the VM. During installation set the username to "user" and hostname to "osgeolive". DO NOT install system updates during lubuntu installation or after the installation is done. At this moment we work with the default kernel included in lubuntu.
  • After the VM is done, login as "user" and open a terminal.
  • Bootstrap the VM:
osgeolive$ cd /tmp
osgeolive$ wget https://github.com/OSGeo/OSGeoLive/raw/master/bin/bootstrap.sh
osgeolive$ chmod a+x bootstrap.sh
osgeolive$ sudo ./bootstrap.sh

This will install Git, the install scripts, and create a link to them from your home directory.

Steps to create the build (repeat as much as needed)

  • Make changes to your project's installation script and commit to Git.
  • Update the git code:
osgeolive$ cd ~/gisvm
osgeolive$ git pull origin master
  • Open file inchroot.sh with an editor and comment out all scripts you do not need for your test.
osgeolive$ cd ~/gisvm/bin
osgeolive$ vi inchroot.sh
  • Always leave un-commented the following scripts: setup.sh, install_services.sh, install_mysql.sh, install_java.sh, install_apache2.sh, install_tomcat6.sh, install_desktop.sh and setdown.sh.
  • Save your changes and execute the build:
osgeolive$ cd ~/gisvm/bin
osgeolive$ sudo ./build_chroot.sh amd64 2>&1 | tee /var/log/osgeolive/chroot-build.log
  • After a while the iso will be created in ~livecdtmp/
  • Do not delete the file ~/livecdtmp/lubuntu-22.04-desktop-amd64.iso as it will be needed for next build (saves time not to download again)
  • Logs are created at /var/log/osgeolive/chroot-build.log
  • Copy the iso and test

Build the Live DVD VM image

Create the VM

The OSGeoLive Virtual Machine creation process is now exactly similar to a plain Lubuntu VM installation. Use the mini iso file that was created from the previous chapter. Instructions can be found Live_GIS_Virtual_Machine

Package the VM

From within the VM, fill empty space with zeros in order to be able to shrink the virtual disk files: 

osgeolive$ sudo ~/gisvm/bin/zerofill.sh

Shrink the virtual machine: 

host$ VBoxManage modifyhd osgeolive.vdi --compact

Convert to vmdk format (more widely compatible): 

host$ VBoxManage clonehd osgeolive.vdi osgeolive-14.0-amd64.vmdk --format VMDK
OR with a recent version of QEMU
host$ qemu-img convert -f vdi -o compat6 -O vmdk osgeolive.vdi osgeolive-14.0-amd64.vmdk

Zip the image up: 

host$ 7z a -mx=9 osgeolive-14.0-amd64.vmdk.7z osgeolive-14.0-amd64.vmdk

Create the md5sum checksums, so which can be used to confirm that the images have been downloaded correctly: 

host$ md5sum *.7z*

Upload the Release

Upload to sourceforge

As of 6.0 the official releases are hosted on sourceforge. To upload you need a sourceforge account and permissions to the osgeo-live project upload. 

rsync -e ssh osgeolive-14.0-amd64.iso username,osgeo-live@frs.sourceforge.net:/home/pfs/project/o/os/osgeo-live/14.0/

Upload to the OSGeo Server

host$ scp -pr osgeolive-gisvm-2.0-alpha5 username@upload.osgeo.org:/osgeo/download/livedvd/

Update the index.html file at: https://svn.osgeo.org/osgeo/livedvd/gisvm/trunk/download/index.html

Check the result at: http://download.osgeo.org/livedvd

Creating a torrent file

Ibiblio has offered torrent hosting, this section needs to include who to contact/how to setup Several tools exist for creating torrents. Below are the key settings you need.

Deluge with the torrent creator plugin has been tested.

  • Make sure you have a copy of the file you want to create a torrent for. Mounted remote drives may work.
  • Web Seed - URL to a web server that hosts the file, adds speed to the torrents especially at the start. (Most clients implement this now)
  • Tracker - There are 2 open and free trackers that have been tested, use one or the other as most clients do not handle multiple trackers yet.
http://tracker.openbittorrent.com/announce
udp://tracker.openbittorrent.com:80/announce

OR 

http://tracker.publicbt.com:80/announce
udp://tracker.publicbt.com:80/announce
  • Upload the .torrent file of your iso file for others to grab
  • Start the torrent on your machine or dedicated seeder, so that others have somewhere to start.
  • There is a possibility of seeding from osgeo machines but a Quality of Service (QoS) system would need to be in place to ensure it does not impact other services.

SVN branches and tags

Naming

  • main development happens in "trunk" (aka HEAD)
  • a branch is split off before release time. Bug fixes (only) happen in it and updates like version 2.1 are tagged from it.
its name might be like "arramagong_2"
  • a tag is a snapshot of the svn at some point in time, aka a release name. It does not make sense to checkin fixes to one. They should ideally be set as read-only after creation to prevent this.
its name might be like "release_20090927_arramagong_2_0"

Creating

cd livedvd/gisvm/

svn copy trunk branches/arramagong_2
svn commit branches/arramagong_2 -m "Splitting off branch for 2.x"

cd branches/arramagong_2/bin/
# something like this, maybe need a for loop or xargs:
sed -e 's+gisvm/trunk+gisvm/branches/arramagong_2+g' *.sh | less   # check
sed -i -e 's+gisvm/trunk+gisvm/branches/arramagong_2+g' *.sh       # execute
cd -
 
svn copy branches/arramagong_2 tags/release_20090927_arramagong_2_0_3
svn commit tags/release_20090927_arramagong_2_0_3 -m "tag release 2.0.3"

Merging

To merge a change from trunk into a release branch use "svn merge", as follows: (in this example r2131 from trunk) 

svn up branches/arramagong_2/
cd branches/arramagong_2/

svn merge -c 2131 https://svn.osgeo.org/osgeo/livedvd/gisvm/trunk
svn diff
svn commit -m "bugfix: bikeshed should be orange! (merge from trunk r2131)"

If you do this a lot you might make a little shell script. Here's one called svn_merge_livefromtrunk.sh: 

#!/bin/sh
# Usage: svn_merge_livefromtrunk <rev number>
svn merge -c $1 https://svn.osgeo.org/osgeo/livedvd/gisvm/trunk

Staging the new release

Website

Log in to live.osgeo.org. 

cd /osgeo/osgeolive
mkdir <versionnumber>

From another machine (ususally adhoc) go to the root of the docs and do 

scp -r /osgeo/livedvd/www/docs/* live.osgeo.org:/osgeo/osgeolive/<versionumber>/

Once done check that it's all good: 

http://live.osgeo.org/archive/versionnumber

Assuming docs are ok, then update the current symlink: 

chmod -R g+w <versionnumber>
rm current
ln -s <versionnumber> current

Download mirror

Upload files to https://sourceforge.net/projects/osgeo-live/files/

Add a new folder for the release, go into it, then scp the file to SourceForge.

Click the box to stage the files for 3 days to give time for the mirrors to populate.

Once the files are ready (no longer say "Pending...") and the download links and redirects from download.osgeo.org are tested & working, set the default download on the SourceForge site to either the full or mini ISO by clicking the "i" information button next to the file and "select all" for all platform types, then click the Save button.
