How to run a shell function as a command in Ansible?

Question

I'm using

nvm

(https://github.com/creationix/nvm), which is essentially a shell script that you source into your shell and then call, for example,

nvm install [version]

. But no matter how I try and call that function, ansible can't seem to find it.

I've tried using the

command

and

shell

modules. I've tried using

become

and

become_user

. I've tried using

sudo -iu

like in https://github.com/leonidas/ansible-nvm/blob/master/tasks/main.yml, but it doesn't work for me. It must be possible though since it works in that file.

How can I run any shell function in Ansible? In this case I've got a

source nvm.sh

in my .zshrc which allows me to execute

nvm

commands from the interactive shell fine.

You'll need to use the shell module, because you want to run shell commands, and you'll need to source in the nvm script into that environment. Something like:

- shell: |
    source /path/to/nvm
    nvm install ...

Whether or not you use become depends on whether or not you want to run the commands as root (or another user).
