Not possible to source .bashrc with Ansible

Question

I can ssh to the remote host and do a source /home/username/.bashrc - everything works fine. However if I do:

- name: source bashrc
  sudo: no
          


        

Answer 1

You have two options to use source with ansible. One is with the "shell:" command and /bin/sh (the ansible default). "source" is called "." in /bin/sh. So your command would be:

- name: source bashrc
  sudo: no   
  shell: . /home/username/.bashrc && [the actual command you want run]

Note you have to run a command after sourcing .bashrc b/c each ssh session is distinct - every ansible command runs in a separate ssh transaction.

Your second option is to force Ansible shell to use bash and then you can use the "source" command:

- name: source bashrc
  sudo: no   
  shell: source /home/username/.bashrc && [the actual command you want run]
  args:
     executable: /bin/bash

Finally, I'll note that you may want to actually source "/etc/profile" if you're on Ubuntu or similar, which more completely simulates a local login.

Answer 2

I know this answer come too late but I have seen in enough code you can use the sudo option -i so:

- name: source bashrc
  shell: sudo -iu {{ansible_user_id}} [the actual command you want run]

As said in the documentation

The -i (simulate initial login) option runs the shell specified by the password database entry of the target user as a login shell.  This means that login-specific
               resource files such as .profile or .login will be read by the shell.  If a command is specified, it is passed to the shell for execution via the shell's -c option.
               If no command is specified, an interactive shell is executed.  sudo attempts to change to that user's home directory before running the shell.  It also initializes
               the environment to a minimal set of variables, similar to what is present when a user logs in.  The Command environment section below documents in detail how the -i
               option affects the environment in which a command is run.

Answer 3

Many responses recommend to source ~/.bashrc but main problem is that ansible shell is not interactive and ~/.bashrc implementation by default ignores non interactive shell (check its beginning).

The best solution for executing commands as user after its ssh interactive login I found is:

- hosts: all
  tasks:
    - name: source user profile file
      #become: yes
      #become_user: my_user  # in case you want to become different user (make sure acl package is installed)
      shell: bash -ilc 'which python' # example command which prints
      register: which_python
    - debug:
      var: which_python

bash: '-i' means interactive shell, so .bashrc won't be ignored '-l' means login shell which sources full user profile

Answer 4

I was experiencing this same issue when trying to get virtualenvwrapper to work on an Ubuntu server. I was using Ansible like this:

- name: Make virtual environment
  shell: source /home/username/.bashrc && makevirtualenv virenvname
  args:
    executable: /bin/bash

but the source command was not working.

Eventually I discovered that the .bashrc file has a few lines at the top of the file that prevent source from working when called by Ansible:

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac

I commented out those lines in .bashrc and everything worked as expected after that.

Answer 5

I found become as best solution:

- name: Source .bashrc
  shell: . .bashrc
  become: true

You can change the user by adding (default: root):

- name: Source .bashrc
  shell: . .bashrc
  become: true
  become-user: {your_remote_user}

I've tried all the options above with ansible 2.4.1.0 and no one works until another two and here is the detail to re-produce the case.

$ cat ~/.bash_aliases 
alias ta="echo 'this is test for ansible interactive shell'";

And this is the ansible test:

- name: Check the basic string operations
  hosts: 127.0.0.1 
  connection: local

  tasks:
  - name: Test Interactive Bash Failure
    shell: ta
    ignore_errors: True

  - name: Test Interactive Bash Using Source
    shell: source ~/.bash_aliases && ta
    args:
      executable: /bin/bash
    ignore_errors: yes

  - name: Test Interactive Bash Using .
    shell: . ~/.bash_aliases && ta
    ignore_errors: yes

  - name: Test Interactive Bash Using /bin/bash -ci
    shell: /bin/bash -ic 'ta'
    register: result
    ignore_errors: yes

  - debug: msg="{{ result }}"

  - name: Test Interactive Bash Using sudo -ui
    shell: sudo -ui hearen ta
    register: result
    ignore_errors: yes

  - name: Test Interactive Bash Using ssh -tt localhost /bin/bash -ci
    shell: ssh -tt localhost /bin/bash -ci 'ta'
    register: result
    ignore_errors: yes

And this is the result:

$ ansible-playbook testInteractiveBash.yml 
 [WARNING]: Could not match supplied host pattern, ignoring: all
