Seven years ago, I wrote a quick post on bootstrapping servers into Ansible. The basic gist of the post was that you can use variables on the Ansible command-line to specify hosts that aren’t part of your inventory or log in via a different user (useful if the host doesn’t yet have a dedicated Ansible user account because you want to use Ansible to create that account). Recently, though, I encountered a situation where this approach doesn’t work, and in this post I’ll describe the workaround.
In one of the Slack communities I frequent, someone asked about using the approach described in the original blog post. However, they were having issues connecting. Specifically, this error was cropping up in the Ansible output (names have been changed to protect the innocent):
fatal: [new-server.int.domain.test]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: [email protected]: Permission denied (publickey,password).", "unreachable": true}
Now, this is odd, because the Ansible command-line being executed included the parameters I mentioned in the original blog post:
ansible-playbook bootstrap.yml -i inventory/hosts -K --extra-vars "hosts=new-server.int.domain.test user=john"
For some reason, though, it was ignoring that parameter and Continue reading
