Erlang RPC for ansible

If you need an Erlang RPC call in an ansible playbook (on the host or via Docker container)

Include path to erlang_rpc and/or erlang_rpc_docker in either:

• ANSIBLE_LIBRARY env variable
• --module-path command line option
• library config entry (see examples)
• simply or copy them to your-playbooks/library directory

Directly on host

Define the task as follows:

- erlang_rpc:
    node: test@localhost
    nametype: longnames
    cookie: secret_cookie
    module: erlang
    function: system_info
    args: "[otp_release]"

Via Docker container

Useful when you don't have Erlang on your host machine or want to attach to one of the Docker overlay networks.

- erlang_rpc_docker:
    node: test@10.0.0.5
    nametype: longnames
    cookie: secret_cookie
    module: erlang
    function: system_info
    args: "[otp_release]" # defaults to "[]"
    network: my-overlay-network  # defaults to "bridge"

Examples

See examples directory for an example of either direct or Docker call. Use example.yml playbook to try it locally.

You need Erlang (for both) and Docker (for the Docker example).
