Initial support has landed in master branch for CentOS 7 and is planned to be released with version 1.24 of juju. Keep in mind that this is an initial release that does have slight differences than its Ubuntu counterpart. We will discuss those issues later on.
First off, to get started you should follow our other two tutorials:
This will give you a ready to go MaaS and Juju environment. Make sure you can bootstrap a trusty state machine before following the next steps to make debugging easier.
There is a nice project made available by Canonical that will facilitate the creation of a new CentOS image compatible with MaaS. We are using MaaS to test this, because its the easiest way to have a locally working lab for testing. Due to limitations to container support for CentOS, we cannot use the local provider yet. More details on that later.
Lets get a local copy of maas-iumagebuilder:
$ bzr branch lp:maas-image-builder $ cd maas-image-builder # python setup.py install
You may need to change the python-stevedore dependency to stevedore in setup.py for the installation to work. Once the image builder is installed, you need to make sure kvm works on the ubuntu machine that you're building the image on. Have a look at https://help.ubuntu.com/community/KVM/Installation for a guide on checking if it's enabled and installing it if necessary.
This will probably take a very long time. You can do the rest of the juju configuration in the meantime. However, before bootstrapping a node with CentOS, the image should be uploaded to MaaS.
maas-image-builder -o centos7-amd64-root-tgz centos --edition 7
maas <session-name> boot-resources create title=centos7 name=centos7 architecture=amd64/generic content@=centos7-amd64-root-tgz
mkdir -p ~/.juju/tools/releases cd ~/.juju/tools/releases cp ~/golang/bin/jujud* . tar -czf juju-1.24-centos7-amd64.tgz jujud tar -czf juju-1.24-trusty-amd64.tgz jujud # Ubuntu tools are only necessary if you want to use Ubuntu machines. rm jujud
rm -rf ~/.juju/tools/streams
juju-metadata generate-tools cp -r ~/.juju/tools /var/www/html chmod -R 755 /var/www/html/tools

juju bootstrap
While these issues are present in this initial release, we are working on remedying them as soon as possible. Some may take longer then others, but we do want to have 1:1 feature set on all supported platforms.
