Displaying output of a remote command with Ansible

Question

In an Ansible role I generate the user s SSH key  After that I want to print it to the screen and pause so the user can copy and paste it somewhere else  So far I have something like this   - name  Generate SSH keys for vagrant user   user  name vagrant generate ssh key yes ssh key bits 2048 - name  Show SSH public key   command   bin cat  home directory  ssh id rsa pub - name  Wait for user to copy SSH public key   pause  prompt  Please add the SSH public key above to your GitHub account    The  Show SSH public key  task completes but doesn t show the output   TASK   Show SSH public key                                                       changed   default    There may be a better way of going about this  I don t really like the fact that it will always show a  changed  status  I did find this pull request for ansible - https   github com ansible ansible pull 2673 - but not sure if I can use it without writing my own module

If you pass the -v flag to the ansible-playbook command  then ansible will show the output on your terminal   For your use case  you may want to try using the fetch module to copy the public key from the server to your local machine  That way  it will only show a  changed  status when the file changes

Prints pubkey and avoid the changed status by adding changed when  False to cat task   - name  Generate SSH keys for vagrant user      user  name vagrant generate ssh key yes ssh key bits 2048  - name  Check SSH public key      command   bin cat  home directory  ssh id rsa pub   register  cat   changed when  False  - name  Print SSH public key   debug  var cat stdout  - name  Wait for user to copy SSH public key      pause  prompt  Please add the SSH public key above to your GitHub account

I m not sure about the syntax of your specific commands  e g   vagrant  etc   but in general     Just register Ansible s  not-normally-shown  JSON output to a variable  then display each variable s stdout lines attribute   - name  Generate SSH keys for vagrant user   user  name vagrant generate ssh key yes ssh key bits 2048   register  vagrant - debug  var vagrant stdout lines  - name  Show SSH public key   command   bin cat  home directory  ssh id rsa pub   register  cat - debug  var cat stdout lines  - name  Wait for user to copy SSH public key   pause  prompt  Please add the SSH public key above to your GitHub account    register  pause - debug  var pause stdout lines
