Running into an issue referencing Anna's dataflow-ops template on deploying the ECS agent.

"containerDefinitions": [
      "entryPoint": [
        "bash",
        "-c"
      ],
      "command": [
        "prefect agent start -q ecs-worker"
      ],

results in error:

Usage: prefect agent [OPTIONS] COMMAND [ARGS]...

Try 'prefect agent -h' for help.

Error: No such command 'start'.

"containerDefinitions": [
      "entryPoint": [
        "bash",
        "-c"
      ],
      "command": [
        "prefect","agent","start","-q","ecs-worker"
      ],

results in what appears to be calling "prefect" with nothing else, as the logs just keep repeating the menu stdout:

Try:

"entryPoint": [],
            "command": [
                "/bin/bash",
                "-c",
                "prefect agent start --work-queue 'ecs-worker'"
            ],

I’m not a prefect person, but this definition for my agent works on my config:

- Name: prefect-agent
          Image: !Ref PrefectImage
          Environment:
            - Name: PREFECT_API_URL
              Value: <http://127.0.0.1:4200/api>
          LogConfiguration:
            LogDriver: awslogs
            Options:
              awslogs-region: !Ref AWS::Region
              awslogs-group: !Ref OrionLogGroup
              awslogs-stream-prefix: agent
          Command: [prefect, agent, start, -q, default]

great suggestions!! @Tim Helfensdörfer giving this a go now

@chicago-joe Entrypoint is not a required property for container definitions: https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_ContainerDefinition.html#ECS-Type-ContainerDefinition-entryPoint I used a base image from Prefect, added a few dependency layers (e.g. pip installs, apt installs), then pushed it to ECR. So the entrypoint is whatever entrypoint is defined by the base Prefect image.

Did you use the cloud formation template? it's much easier than manually deploying task definitions https://github.com/anna-geller/dataflow-ops/blob/main/infrastructure/ecs_cluster_prefect_agent.yml

@Anna Geller I had followed the ecs_agent setup instructions within the prefect-recipes repo a few weeks ago --- I will redo and follow the cloud formation template. Moving forward, should I rely on this as a base configuration template? Not a terrible thing to have so many resources, but I'm starting to lose track of which one is the recommended way to go hahaha

your spot on, my mistake, corrected
