sysconf profile for gitted-gitted systems

Gitted provides a way to import/export machine state. In the usual case, a "gitted" system is an LXC container.

The metagitted profile is meant to import/export the set of LXC containers. That is: a push-to-deploy solution for bringing up new guest services (LXC containers) and update them with git push.

How to setup

To enable the meta-gitted host (the one that runs LXC containers), you need to setup Sysconf.

As root, setup sysconf from the metagitted-demo sysconf directory:

apt-get install curl
curl -L https://github.com/geonef/metagitted.demo/archive/master.tar.gz | tar xz -C / --strip-components=1
/sysconf/sysconf.base/tree/usr/bin/sysconf compile install update

Then, choose a directory somewhere from where you will administrate the meta-gitted system with git push and pull. There, clone the metagitted-demo repository:

git clone https://github.com/geonef/sysconf.metagitted.git
git clone https://github.com/geonef/metagitted.demo.git && cd metagitted.demo

Then add the remote. If it's a directory local to the metagitted system:

git remote add metagitted "ext::gitted git-remote-command %S"

If it's from outside through SSH (replace metagitted.host.net with the host name):

git remote add metagitted "ext::ssh [email protected] gitted git-remote-command %S"

You're done! Ready to make push and pulls...

Push & pull

To deploy, for example, gitted.clipperz.demo:

git fetch https://github.com/geonef/gitted.clipperz.demo.git master:demo
git push metagitted master demo

When the command ends, the clipperz application should be up and running through a newly-created LXC container demo.

You can visit the app by opening the host IP into your web browser, since the TCP port 80 is forwarded as configured in /etc/metagitted/ipv4.forward.tab.

After you have made changes to ClipperZ, the MySQL data will be extracted into Git commits when you make:

git fetch metagitted

You can merge the changes into your local demo branch by making:

git checkout demo
git merge metagitted/demo

You can duplicate the application by creating a metagitted/demo2.guest file based on the demo.guest file, committing it and making:

git push metagitted master demo:demo2
