• You are working on your playbook at ~/dev/mycoolplaybook
• You decide to extract a role to post it on the galaxy
  • Copy coolrole from mycoolplaybook
  • Copy to ~/somewhere/github/mycoolrole
    • Git init the directory and add in the galaxy metadata.
    • Push it to github.
    • Add it to the galaxy.
  • Galaxy install the role.
  • Rename the role declaration in your site.yml to match the new name.
• Run the role to make sure it works after all of that shuffling around.
