@rgaiacs how do we co-ordinate rolling this out when it's time? Would getting #3178 in first help?

how do we co-ordinate rolling this out when it's time?

@arnim and @rgaiacs did not get a decision from GESIS leadership regarding how they want to handle the container image registry yet. We are trying to get this decision as soon as possible. We will update here regarding way to co-ordinate.

how do we co-ordinate rolling this out when it's time?

@arnim and @rgaiacs spoke with other people at GESIS today. There will be a follow up meeting on Monday.

@arnim and @rgaiacs explained that this change is coming and GESIS will have to choose from (1) migrate to a bare metal at Hetzner so that we can share a deployment in this repository or (2) provide more time for @rgaiacs to port the new chart to GESIS, specially in consideration that @rgaiacs will be on annual leave in March and June.

@yuvipanda do you think this will be ready to merge before the end of April?

Would getting #3178 in first help?

Not at the moment. @arnim and @rgaiacs don't know what the leadership at GESIS will decide.
