Where to work?

  • We deploy from Complector using:
    • /opt/salt/nasqueron-operations as our local copy of rOPS, authoritative for Salt
    • /opt/salt/staging for web and application content
  • You need to belong to the ops group to be able to have access and have write-rights on the repository
  • Check if the Salt primary server is alive, if not service salt-master start

Deployment workflow

Apply a new Salt state

  1. On your computer or a devserver, prepare and upload a change to Differential against rOPS repository
  2. Merge it to main, we deploy from the min branch
  3. Ask Salt to apply the change
  4.  Log on #nasqueron-operations something like [Eglide] New user account: amj (D607)

If you want to test it before merging, you can push a branch to datacube remote: ssh://windriver.nasqueron.org/datacube/git/operations.git

Note `arc` isn't available on Complector, as there are too many PHP dependencies.

Deploy a web site

  1. Commit as needed
  2.  Go to /opt/salt/staging relevant subdirectory and fetch code
  3. Ask Salt to apply the matching state (if in doubt, a full run is salt '*' state.highstate test=True)

Salt commands

Remote server

To apply one state or a directory:

salt eglide state.apply roles/shellserver/users

To apply all:

salt eglide state.highstate

Replace eglide by the server name, or * to target all machines.

When you've a new state, ensure it's called from top.sls file, as the repository root.

Salt primary server

If you wish to deploy directly to the primary server, you've two solutions:

1. Run a minion there and use salt complector</salt> normally 2. Replace salt by salt-call --local: sudo salt-call --local state.apply test

This should run as root, so the recommended alias is alias salt sudo salt (tcsh syntax)

The second method seems to be currently needed for Vault tokens.
