Thanks Peter, removing the global ‘become: true’ flag in the playbook did not change the outcome for me.

Had to explicitly define galaxy_become_users and galaxy_remote_users like so:

galaxy_become_users:

  privsep: root

  errdocs: root

  galaxy: galaxy

  root: root

galaxy_remote_users:

  privsep: foo

  errdocs: foo

  galaxy: foo

  root: foo

Where ‘foo’ is the user you want to SSH with.

It is not actually, in my investigation, coming from an Ansible default. There's code inside the Galaxy role that tries to figure out which user to use for remote_user (the one used in SSH) and when it is run with `become: true` ends up incorrectly choosing root. However people more knowledgeable than me don't have this problem. Perhaps something changed in some version somewhere?

Anything attempting to login remotely as root must be rejected.  Peter's policy approach is good for that.  Most modern linices will not allow a remote root login, which is correct.  There are SSH ways to accomplish the same thing, but depend on trust at both ends.  The defaulting by Ansible is reprehensible, but usually should be expected to fail.

Hi there

I found I had this problem too, when the `become: true` applied to the whole Galaxy play. My current top level playbook (at https://github.com/pvanheus/masters_galaxy_ansible/blob/master/galaxy.yml#L25) now applies `become: true` as it is needed, and does not apply it to the `galaxyproject.galaxy` role. I found that this avoids Ansible trying to log in as the root user.

Hi there,

Would anyone happen to know why Ansible tries to connect to a remote host (CentOS 7) using 'root' during Galaxy role installation?

My playbook has been configured to connect to the remote host using a different user account via SSH, however, the role installation is not honoring this for some reason and continues to use root. The remote host has had SSH root login disabled for security reasons and setting various galaxy user/privsep/become/remote user variables in the group_vars has not had any effect.

TASK [galaxyproject.galaxy : Create galaxy_root] *

fatal: [server_name]: UNREACHABLE! => {"changed": false, "msg": "Invalid/incorrect password: Permission denied, please try again.\r\nPermission denied, please try again.\r\nroot@server_name: Permission denied (publickey,password).", "unreachable": true}

Thanks,

Sandra
