ChatOps

ChatOps setup using mattermost, ansible, hubot

Will work on

This will only work on RHEL 7, postgresql 9.2 (default on RHEL 7)

Run playbook

To run the play book first add a hosts file with the ip-addresses of the hosts that the playbook needs to run on. Then use the following command to play: # ansible-playbook play.yml -i hosts

Reinstallation of the database is supported by setting the following option in the defaults of postgresql to yes (default is no and if a DB already exist the task will fail): postgresql_drop_old_installation: no

Test db connection

Attempt to connect with the new created user to verify everything looks good, for example:

# psql --host=127.0.0.1 --dbname=mattermost --username=mmuser --password
