Mise-à-disposition

Ajoutons notre dépendance au logiciel ansible.

~/projet-cloud/ $ yq -i e '.dependencies["ansible.com"]="*"' pkgx.yaml

Ré-activons notre environnement contextuel.
Cela va utiliser les logiciels packer et terraform depuis le cache de pkgx et mettre en cache le logiciel ansible nouvellement référencé.

~/projet-cloud/ $ dev off
env -packer.io -terraform.io^1.6
~/projet-cloud/ $ dev on
   ~/.pkgx/ansible.com/v2.17.3
env +packer.io +terraform.io^1.6 +ansible.com

La commande ansible est maintenant disponible dans notre environnement.

               pattern

Define and run a single task 'playbook' against a set of hosts

positional arguments:
  pattern               host pattern

options:
  --become-password-file BECOME_PASSWORD_FILE, --become-pass-file BECOME_PASSWORD_FILE
                        Become password file
  --connection-password-file CONNECTION_PASSWORD_FILE, --conn-pass-file CONNECTION_PASSWORD_FILE
                        Connection password file
  --list-hosts          outputs a list of matching hosts; does not execute anything else
  --playbook-dir BASEDIR
                        Since this tool does not use playbooks, use this as a substitute playbook directory. This sets the relative path for many
                        features including roles/ group_vars/ etc.
  --task-timeout TASK_TIMEOUT
                        set task timeout limit in seconds, must be positive integer.
  --vault-id VAULT_IDS  the vault identity to use. This argument may be specified multiple times.
  --vault-password-file VAULT_PASSWORD_FILES, --vault-pass-file VAULT_PASSWORD_FILES
                        vault password file
  --version             show program's version number, config file location, configured module search path, module location, executable location and
                        exit
  -B SECONDS, --background SECONDS
                        run asynchronously, failing after X seconds (default=N/A)
  -C, --check           don't make any changes; instead, try to predict some of the changes that may occur
  -D, --diff            when changing (small) files and templates, show the differences in those files; works great with --check
  -J, --ask-vault-password, --ask-vault-pass
                        ask for vault password
  -K, --ask-become-pass
                        ask for privilege escalation password
  -M MODULE_PATH, --module-path MODULE_PATH
                        prepend colon-separated path(s) to module library (default={{ ANSIBLE_HOME ~
                        "/plugins/modules:/usr/share/ansible/plugins/modules" }}). This argument may be specified multiple times.
  -P POLL_INTERVAL, --poll POLL_INTERVAL
                        set the poll interval if using -B (default=15)
  -a MODULE_ARGS, --args MODULE_ARGS
                        The action's options in space separated k=v format: -a 'opt1=val1 opt2=val2' or a json string: -a '{"opt1": "val1", "opt2":
                        "val2"}'
  -e EXTRA_VARS, --extra-vars EXTRA_VARS
                        set additional variables as key=value or YAML/JSON, if filename prepend with @. This argument may be specified multiple times.
  -f FORKS, --forks FORKS
                        specify number of parallel processes to use (default=5)
  -h, --help            show this help message and exit
  -i INVENTORY, --inventory INVENTORY, --inventory-file INVENTORY
                        specify inventory host path or comma separated host list. --inventory-file is deprecated. This argument may be specified
                        multiple times.
  -k, --ask-pass        ask for connection password
  -l SUBSET, --limit SUBSET
                        further limit selected hosts to an additional pattern
  -m MODULE_NAME, --module-name MODULE_NAME
                        Name of the action to execute (default=command)
  -o, --one-line        condense output
  -t TREE, --tree TREE  log output to this directory
  -v, --verbose         Causes Ansible to print more debug messages. Adding multiple -v will increase the verbosity, the builtin plugins currently
                        evaluate up to -vvvvvv. A reasonable level to start is -vvv, connection debugging might require -vvvv. This argument may be
                        specified multiple times.

Privilege Escalation Options:
  control how and which user you become as on target hosts

  --become-method BECOME_METHOD
                        privilege escalation method to use (default=sudo), use `ansible-doc -t become -l` to list valid choices.
  --become-user BECOME_USER
                        run operations as this user (default=root)
  -b, --become          run operations with become (does not imply password prompting)

Connection Options:
  control as whom and how to connect to hosts

  --private-key PRIVATE_KEY_FILE, --key-file PRIVATE_KEY_FILE
                        use this file to authenticate the connection
  --scp-extra-args SCP_EXTRA_ARGS
                        specify extra arguments to pass to scp only (e.g. -l)
  --sftp-extra-args SFTP_EXTRA_ARGS
                        specify extra arguments to pass to sftp only (e.g. -f, -l)
  --ssh-common-args SSH_COMMON_ARGS
                        specify common arguments to pass to sftp/scp/ssh (e.g. ProxyCommand)
  --ssh-extra-args SSH_EXTRA_ARGS
                        specify extra arguments to pass to ssh only (e.g. -R)
  -T TIMEOUT, --timeout TIMEOUT
                        override the connection timeout in seconds (default depends on connection)
  -c CONNECTION, --connection CONNECTION
                        connection type to use (default=ssh)
  -u REMOTE_USER, --user REMOTE_USER
                        connect as this user (default=None)

Some actions do not make sense in Ad-Hoc (include, meta, etc)
