Ansible cheat sheet¶

This page will cover some helpful one-line commands we can execute with Ansible to accomplish various tasks. Always run git pull and git submodule update before executing these commands.

Synchronize a non-canonical site with the live site¶

ansible-playbook sync.yml -l mysite.local 

• This works on test and dev sites.
• Depending on the sync strategy on the website inventory, it will pull from last night's backup, sync directly from the live site, or use the Pantheon API to make a backup/download.
• Only sites that pull from backup can sync to a site that's not on your local machine at present (I'll fix this at some point).

Ad-hoc examples¶

Roll back a site to the latest commit (e.g. after a failed merge or failed local update):¶

ansible --become --become-user="{{ run_as_user }}" -m shell -a 'cd {{civiroot}} && git clean -fd {{civiroot}} && git reset --hard HEAD'  mysite1.local,mysite2.local

Update all dev sites to the latest version of a submodule¶

ansible --become --become-user="{{ run_as_user }}" -m shell -a 'cd {{webroot}}/{{civicrm_custom_path}}/extensions/com.megaphonetech.monitoring && git checkout master && git pull && cd .. && git add  com.megaphonetech.monitoring && git commit -m"Updated monitoring submodule" && git push' 'maintenance_civi:&websites_dev'

Send a drush command to multiple sites¶

This is trickier to handle places where we don't have root, but works.

ansible --become --become-user="{{ run_as_user }}" -m shell -a "PATH=\$HOME/bin:\$PATH; drush --root={{ webroot }} pm-disable -y print" 'maintenance_drupal'

Update a Civi extension only on certain sites¶

ansible --become --become-user="{{ run_as_user }}" -m shell -a "PATH=\$HOME/bin:\$PATH; cv --cwd={{ webroot }} ext:download --force extendedreport" site1.local,site2.local
ansible --become --become-user="{{ run_as_user }}" -m shell -a "cd {{ webroot }}; git add .; git commit -m'ExtendedReport 5.16'; git push" site1.local,site2.local

Send an arbitrary SQL statement to all Civi test instances with maintenance contracts¶

ansible --become --become-user="{{ run_as_user }}" -m shell -a "PATH=\$HOME/bin:\$PATH; echo \"UPDATE civicrm_job SET is_active = 0 WHERE api_action = 'group_rebuild';\" | cv --cwd={{ webroot }} sql" 'maintenance_civi:&websites_test'

Set CLI PHP version across all servers¶

This is an example of server-level changes (others are site-level).

ansible  --become -m command -a 'update-alternatives --set php /usr/bin/php7.4' vps

Copy a local file to all servers¶

ansible --become -m copy -a "src=/home/jon/Downloads/goodphp81.php.ini dest=/etc/php/8.1/fpm/php.ini mode=0644 owner=root group=root" lamp

Run a non-command module across all servers¶

ansible --become -m user -a"name=joseph state=absent remove=yes" vps

Clear templates_c and flush cache on all maintenance servers¶

ansible --become -m shell -a "cd {{ webroot }}/wp-content/uploads/civicrm; rm -rf templates_c; cv flush" 'maintenance_civi:&maintenance_wp:&websites_live'
ansible --become -m shell -a "cd {{ webroot }}/sites/default/files/civicrm; rm -rf templates_c; cv flush" 'maintenance_civi:&maintenance_drupal:&websites_live'

Push changes to live and/or test sites¶

ansible-playbook upgrade.yml --tags update-sites -l '[sitename]' 
ansible-playbook upgrade.yml --tags update-sites -l [sitename] 
# Do two or more sites - no space after the comma
ansible-playbook upgrade.yml --tags update-sites -l [sitename], [sitename]
# Wildcards require the single quotes. I like this approach because it's quicker to type
ansible-playbook upgrade.yml --tags update-sites -l '[wildcard keyword]*' 
# Everything together
ansible-playbook upgrade.yml --tags update-sites -l '[wildcard keyword]*,*[wildcard keyword]*'
