OpenStack Heat template example: Deploy Salt Cluster with HOT

readme.md

Deploy SaltStack with OpenStack Heat.

This is an example of HOT(Heat Orchestration Template), which deploy SaltStack cluster, with 1 master node and 5 minion nodes.

You can build it with one command.

heat stack-create saltstack \
  -u https://gist.github.com/kjtanaka/7935747/raw/6fcfce4d28b9d5dd7a5b824b678151cc64f522b7/deploy_salt.yml \
  -P "keyname=<key_name>;imagename=<image_name>"

For example, if the key and the image look like below,

nova keypair-list
+---------------+-------------------------------------------------+
| Name          | Fingerprint                                     |
+---------------+-------------------------------------------------+
| mykey         | xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx |
+---------------+-------------------------------------------------+
nova image-list
+--------------------------------------+--------------------------------+--------+--------------------------------------+
| ID                                   | Name                           | Status | Server                               |
+--------------------------------------+--------------------------------+--------+--------------------------------------+
| 68b33e91-4aec-4126-8bb2-770ec27ab1fe | F19-cfntools                   | ACTIVE |                                      |
+--------------------------------------+--------------------------------+--------+--------------------------------------+

Then, the command will be like this.

heat stack-create saltstack \
  -u https://gist.github.com/kjtanaka/7935747/raw/6fcfce4d28b9d5dd7a5b824b678151cc64f522b7/deploy_salt.yml \
  -P "keyname=mykey;imagename=F19-cfntools"
