Can we run multiple modules in ansible using single ad-hoc command?

Question

I know it's possible to run multiple adhoc commands one after the other for each module and using playbook.

Playbook:

---

- hosts: webservers
  tasks:
   - name: create .ssh dir
     file: path ~/.ssh state=directory
   - name: copy pub key
     copy: src:~/.ssh/id.rsa_pub dest=~/.ssh/authorized_keys

I want the above to execute using adhoc in one line. Is it possible to do so?

Answer 1

No, it is not possible.

ansible command accepts only one set of arguments for a single module and its parameters.

-m MODULE_NAME, --module-name=MODULE_NAME
module name to execute (default=command)

Answer 2

Use ansible-console and heredoc instead:

ansible-console <<<"cd webservers"$'\n'"setup"$'\n'"file path=~/.ssh state=directory"$'\n'"copy src=~/.ssh/id.rsa_pub dest=~/.ssh/authorized_keys"

This is technically one hack of a line but has no error handling. And is pretty not readable.

ansible-console alone eventually could do the trick. It's a pretty neat tool.

Answer 3

We can actually use the below single ad-hoc command using Ansible module and Linux command:

ansible clientvm -m shell -a "mkdir ~/.ssh" && scp ~/.ssh/id_rsa.pub root@clientvm:~/.ssh/authorized_keys

In the above command, clientvm is the hostname where we are creating the directory and copying the file into it as per above requirement from the Ansible controller node.
