Aaron Goebel
02/07/2024, 8:28 PMWe have tried to create a custom docker registry for logging into ecr via the token. Running the block in isolation works. But the agent always fails to authenticate when triggered to run a container with said block

02/07/2024, 8:33 PMwe recently added support for providing registry credentials if you're using a docker worker: https://github.com/PrefectHQ/prefect-docker/pull/102

02/07/2024, 8:34 PMyou'd have to switch to a worker, but it's very very similar to using an agent with a docker infra block

02/07/2024, 8:39 PMthanks for the quick reply! I'm unfamiliar with the workers--do they phase out agents?

Kevin Grismore
02/07/2024, 8:41 PMthey're like agents, but provide a default, infra-specific template that you can then override on each deployment if you'd like, eliminating the need for infra blocks

02/07/2024, 9:32 PMI'm not sure this is going to work because the credentials are sourced via a token.... looks like we'd probably need to make a custom worker

02/07/2024, 9:41 PMI believe you can use your token in the password field

02/07/2024, 9:42 PMahhh yeah you'd have to update the field in the block each time there's a new token

02/07/2024, 9:43 PMThat's why I was getting a new token to login with the DockerContainer block every-time it was going to run--but it was not authenticating when running from the Agent. If i take the same approach with the worker will it be any different?
