limit

Further limit selected hosts to an additional pattern.

skip_tags

Only run plays and tasks whose tags do not match these values.

startattask

Start the playbook at the task matching this name.

tags

Only run plays and tasks tagged with these values.

extra_vars

Set additional variables in a key=value format for the playbook.

module_path

Prepends specified paths to the module library path list.

check

Executes a dry run, showing what changes would be made without making them.

diff

Shows the differences in files and templates when changing them.

flush_cache

Clears the fact cache for every host in the inventory.

Starting with v1.2.0: The action automatically normalizes SSH keys (converts CRLF to LF, adds trailing newlines, validates format).

Note: For bastion host or ProxyCommand issues on older versions, see the SSH Authentication section for workarounds.

config_file

Path to an ansible.cfg configuration file to use (sets ANSIBLE_CONFIG).

no_color

Disables colorized output.

output_callback

Sets the stdout callback plugin for Ansible output (e.g. yaml, json, minimal).

callbacks_enabled

Comma-separated list of enabled callback plugins (e.g. profile_tasks,timer).

strategy_plugin

Specifies the strategy plugin to use (e.g. linear, free, mitogen_linear).

gather_subset

Limits the scope of gathered facts (e.g. !all,!min,network).

gather_timeout

Timeout in seconds for gathering facts (0-3600, 0 = ansible default).

fact_path

Path to local fact files loaded as host facts.

fact_caching

Caching method to use for facts (e.g. jsonfile, redis, memory).

factcachingtimeout

Timeout in seconds for the fact cache (0 = no expiry).

poll_interval

Interval in seconds for polling async tasks (0-3600, 0 = ansible default).

maxfailpercentage

Maximum percentage of hosts that can fail before the playbook aborts (0-100).

anyerrorsfatal

Treats any task error as fatal, aborting the whole play.

sshtransfermethod

Method for file transfer over SSH (e.g. scp or sftp).

vaultpasswordfile

Path to a file containing the vault password (alternative to vault_password).

privatekeyfile

Path to a file containing the SSH private key (alternative to private_key).

temp_dir

Directory for Ansible temporary files.

Advanced Configuration

Beyond the basic inputs, the action exposes Ansible's advanced execution options. Each input is also readable from an environment variable named ANSIBLE<INPUTNAME_UPPERCASE>, so the two forms below are equivalent — set them as action inputs via with: or as environment variables via env:.

Heads-up: use the action's ANSIBLE<INPUTNAME> spelling, not

Ansible's own native variable name. A few differ: strategy_plugin →

ANSIBLESTRATEGYPLUGIN (Ansible's native var is ANSIBLE_STRATEGY),

factcaching → ANSIBLEFACTCACHING (native: ANSIBLECACHE_PLUGIN),

configfile → ANSIBLECONFIGFILE (native: ANSIBLECONFIG).

- name: Deploy with advanced Ansible tuning
  uses: arillso/action.playbook@master
  with:
    playbook: deploy.yml
    inventory: ansible_hosts.yml
    # Performance: run plays free of the per-host lockstep, cache facts
    strategy_plugin: free
    fact_caching: jsonfile
    factcachingtimeout: '7200'
    # Only gather the facts you need
    gather_subset: '!all,!min,network'
    gather_timeout: '30'
    # Richer output and timing breakdown
    output_callback: yaml
    callbacksenabled: profiletasks,timer
    # Fail fast across a fleet
    maxfailpercentage: '25'
    anyerrorsfatal: 'true'
  env:
    ANSIBLEHOSTKEY_CHECKING: 'false'

Note: fact_caching: jsonfile also needs a cache directory. Set it via

env: { ANSIBLECACHEPLUGINCONNECTION: /tmp/ansiblefacts } or a custom

config_file. Plugin-specific options that have no dedicated input are

always reachable through env: or an ansible.cfg referenced by

config_file.

SSH Authentication

✨ New in v1.2.0+

>

SSH private keys are automatically normalized:

- Windows line endings (CRLF) → Unix format (LF)

- Missing trailing newlines are added

- Format validation (RSA, OpenSSH, EC, DSA)

Basic Usage

- name: Deploy with Ansible
  uses: arillso/action.playbook@1.2.0
  with:
    playbook: deploy.yml
    inventory: ansible_hosts.yml
    privatekey: ${{ secrets.SSHPRIVATE_KEY }}
  env:
    ANSIBLEHOSTKEY_CHECKING: 'false'

Storing SSH Keys in GitHub Secrets

🔒 Security Warning: NEVER commit private SSH keys to your repository!

• Go to repository Settings → Secrets and variables → Actions
• Click "New repository secret"
• Name: SSHPRIVATEKEY
• Value: Paste your entire private key (including -----BEGIN/END----- headers)
• Click "Add secret"

Your key must have proper PEM headers (-----BEGIN RSA PRIVATE KEY----- or similar). Line endings and trailing newlines are automatically fixed in v1.2.0+.

Troubleshooting

For versions < 1.2.0 or edge cases, use extra_vars to pass the key file path:

- name: Setup SSH Key
  run: |
    echo "${{ secrets.SSHPRIVATEKEY }}" > /tmp/ssh_key
    chmod 600 /tmp/ssh_key
name: Deploy
  uses: arillso/action.playbook@master
  with:
    playbook: deploy.yml
    inventory: ansible_hosts.yml
    extravars: ansiblesshprivatekeyfile=/tmp/sshkey

For verbose SSH debugging, set verbose: 4 in the action inputs.

Example Usage

- name: Play Ansible Playbook
  uses: arillso/action.playbook@master
  with:
    playbook: tests/playbook.yml
    inventory: tests/hosts.yml
    galaxy_file: tests/requirements.yml
  env:
    ANSIBLEHOSTKEY_CHECKING: 'false'
    ANSIBLEDEPRECATIONWARNINGS: 'false'
