Looks like the above issue is that Ansible is not able to authenticate with the server. By default it looks to try and use ssh keys, but I don’t have any passwordless ssh keys set up for Ansible to use so it fails while attempting to connect. The work around it to make sure you have sshpass installed and then specify –ask-pass to the end of the command.
This is part of a series of posts on backing up and restoring a backup for Matrix Synapse server. Synapse was installed using the matrix-docker-ansible deployment which while a little complicated can greatly ease management later on down the road. All the main components are in docker containers so we need to use docker to access.
