Want to play with Ubuntu’s awesome Juju but don’t want to get into the hassle of getting EC2 configured?
It’s actually pretty easy to set up a local provider to experiment with this.
You need to be running Ubuntu 12.04 (yes, it’s not released yet but you can use the beta version or daily images). Oh, and you can install this on a virtual machine if you really don’t want Juju to mess with your actual system.
Make sure to have a valid SSH key, if you don’t have one, create it with
|
1 |
ssh-keygen |
Then
|
1 |
apt-get install juju llibvirt-bin lxc apt-cacher-ng zookeeper |
Once the packages are installed, run
|
1 |
newgrp libvirtd |
this adds you to the libvirtd group at runtime.
Then run juju bootstrap. Juju will complain about a config file or something. Ignore it! and then edit .juju/environments.yaml and replace everything on that file with this:
|
1 2 3 4 5 6 |
environments: local: type: local data-dir: /tmp/local-dev admin-secret: b3a5dee4fb8c4fc9a4db04751e5936f4 default-series: oneiric |
The admin-secret is a MD5 random key, you should probably generate your own with something like this:
|
1 |
head -c 10 /dev/urandom |md5sum |
Then finally it’s time to bootstrap things:
|
1 |
juju bootstrap |
This will exit pretty quickly, but things are not ready yet. Note that it will take a few minutes to get packages and actually prepare the nodes.
Once your juju is bootstrapped you can follow the rest of the steps here:
