I just tried secrets unset for some secrets, and as expected, that triggered a new deploy.
However it seemed to fail with:
Monitoring Deployment You can detach the terminal anytime without stopping the deployment 3 desired, 2 placed, 1 healthy, 0 unhealthy [health checks: 2 total, 2 passing] v10 running - Deployment is running Error 1 error occurred: * server returned a non-200 status code: 504
So given it says 2 were placed … would that mean that 2 out of the 3 servers are live and receiving traffic, while 1 is not? And so be out of sync in terms of secrets (in this case) available.
Or does traffic only get migrated over to the new version once they all are ‘placed’ and all ‘healthy’?
Only … given the random failures that happen during deploys, it’s fine if traffic never gets sent to them. Less good if it does, and part way through, the rest fail. Ending up with some weird half/half version/roll-back situation.
