# 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):

```shell

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

```shell

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.

```shell

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

```shell

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

```shell

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'

````

#### 

```

# Check Civi version of all dev sites

ansible --become --become-user="{{ run_as_user }}" -m shell -a "PATH=\$HOME/bin:\$PATH; cv --level=cms-full --cwd={{ webroot }} vars:show | grep CIVI_VERSION" 'maintenance_civi:&websites_dev'

# Find which dev sites have Shoreditch enabled

ansible --become --become-user="{{ run_as_user }}" -m shell -a "PATH=\$HOME/bin:\$PATH; cv --level=cms-full --cwd={{ webroot }} ext:list --local | grep shoreditch" 'maintenance_civi:&websites_dev'

# Send a cv command with JSON

ansible --become --become-user="{{ run_as_user }}" -m shell -a "PATH=\$HOME/bin:\$PATH; cv --level=cms-full --cwd={{ webroot }} setting:set '{\"stripe_moto\": []}'" maintenance_civi  

```

#### Set CLI PHP version across all servers

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

```shell

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

```

#### Copy a local file to all servers

```shell

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'

```

### Install an unreleased version of an extension

```shell

# Need the key of the extension and the URL of the .zip file as arguments to `--bare`.

ansible --become -m shell -a "cv --cwd={{ webroot }} ext:download --force 'civirules@https://lab.civicrm.org/JonGold/civirules/-/archive/predata-fix-567/civirules-predata-fix-567.zip'" crcl.local

ansible --become -m shell -a 'cd {{ webroot }} && git add {{ webroot }}/{{ civicrm_custom_path }}/extensions && git commit -m"CiviRules 5.67 fix" && git push' crcl.local

```

### Push changes to live and/or test sites

```shell

ansible-playbook update.yml -l [sitename] 

# Do two or more sites - no space after the comma

ansible-playbook update.yml -l [sitename],[sitename]

# Wildcards require the single quotes. I like this approach because it's quicker to type

ansible-playbook update.yml -l '[wildcard keyword]*' 

# Everything together

ansible-playbook update.yml -l '[wildcard keyword]*,*[wildcard keyword]*' 

```
