I am focusing on rackspace for salt-cloud.
Initially I build a cloud server, and then convert it into a salt-master. You could use your laptop, but thats not a particularly long term solution.
Installing salt onto ubunutu 12.04:
sudo apt-get -y install python-software-properties sudo add-apt-repository -y ppa:saltstack/salt sudo apt-get update sudo apt-get -y install salt-master sudo apt-get -y install salt-minion sudo apt-get -y install salt-cloud ## delete as applicable
We now have a salt-master on a host, lets put salt-cloud up
Basic Directory Layout¶
There are two directorys to worry about
- /etc/salt - basic config for both cloud, master, minion
- /srv/salt - location of all the files we are going to put on minion. (Its more complex than that but thats the simplest explantion)
configure the cloud¶
In /etc/salt we want to create / adjust two files, /etc/salt/cloud.providers holds credentials and identifiers for our cloud account. /etc/salt/cloud.profiles
salt-cloud is going through a revamp of it’s configuration, and the new stuff is not quite ready for prime time. This works to date.
my-rackspace-config: # Set the location of the salt-master # minion: master: saltmaster.example.com # Configure Rackspace using the OpenStack plugin # identity_url: 'https://identity.api.rackspacecloud.com/v2.0/tokens' compute_name: cloudServersOpenStack protocol: ipv4 # Set the compute region: # compute_region: DFW # Configure Rackspace authentication credentials # user: myname tenant: 123456 apikey: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx provider: openstack
mikado_512: provider: mikado-rackspace size: 512MB Standard Instance image: Ubuntu 12.04 LTS (Precise Pangolin)
I have linked this minimal profile called mikado_512, to the rackspace account mikado-rackspace, with the sizes and images configured from (tbd).
Bring up our first minion¶
sudo salt-cloud -p mikado_512 minone
We are telling salt-cloud to create a minion, using the mikado_512 profile defined above, and the provider details, and call that minion minone.
When it exists we can do lots of fun things with the minion, from salt-master.
171 salt '*' test.ping 172 sudo salt '*' test.ping 173 sudo salt 'myinstance' test.ping 174 sudo salt 'myinstance' sys.doc 175 sudo salt 'myinstance' timezone.get_zone 176 sudo salt 'myinstance' cmd.run 'ls -l /tmp' 177 sudo salt 'myinstance' pkg.install emacs
This is all very well, but still fairly manual and prescriptive. Lets move on.
