Remote Env Setup Queries

I’m working on a custom module but having issues with the environment setup on the remote server.

How should the remote environment variables be correctly setup. I’ve been looking here http://docs.ansible.com/ansible/dev_guide/developing_modules.html but not found anything yet or I might have simply missed it.

At the moment I’m doing a shell task, along the lines of “. PATH/env.sh && myscript.py”, also doing sudo: yes, sudo_user: “{{ remote_user }}”

Ideally I’ld like to know how I can specify PATH as a field for my module, then before the module executes on the target server the env.sh is executes before the actual task.

Or if people know another module which does similar I don’t mine reviewing that and working it out for myself. I just can’t figure out how to source the shell script beforehand.

Cheers,

The environment: directive exists so each module does not need to implement what you are asking.

Where can I find a list of all the options that environment allows and how to use it correctly?

I’ve found this http://docs.ansible.com/ansible/playbooks_environment.html

What I’m trying to do is specify a script to execute which will setup the enviroment prior to execution, but that is either not an option or I just can’t find the documentation.

Cheers,

What I’m hoping to find it something like this;

$ cat play.yml

  • hosts: localhost
    tasks:

  • name: Test that my module works
    MY_CUSTOM_MODULE:
    register: result
    environment:
    script: ${WL_HOME}/server/bin/setWLSEnv.sh

  • debug: var=result
    $

but script doesn’t work, so not sure what it should be. It might be environment lacks this ability.

It is for setting environment variables, it should not execute anything.

Is their anyway I can get environment to source a shell script?

Also from within a custom module how do I define default environment variables? e.g. the user defines a base dir and the module defines various variables based upon the user provided value?

7

If I execute $ . ${WL_HOME}/server/bin/setWLSEnv.sh
I get 36 new and 2 modified environment variables, ideally I don’t want the consumer of my custom module to not have to specifiy these manually. I would like the consumer to specify WL_HOME, then get the ansible module framework to execute ${WL_HOME}/server/bin/setWLSEnv.sh

If ansible isn’t able to do this, I’ll try and find a work around. But it might be a useful feature for something like environment_source, so it sources the scripts listed. Or maybe like unsafe where you can do source and it will source the file not define it.
