Sorry about my ignorance, but, the container was not to be running in the background?

[buchdag]

Hi. Additional configuration is required if you want to run this container on ECS.

Please check the DOCKER_PROVIDER environment variable under the Optional container environment variables section of the Readme.

[leoddias]

@buchdag
Thanks for the answer!

Now i put the companion container's env DOCKER_PROVIDER = ecs DEBUG=true AND
ECS_ENABLE_CONTAINER_METADATA=true in /etc/ecs/ecs.config (because it was disabled by default)
and i maked a reboot.

Now, when i run "docker inspect", i got this new mount option:

"Source": "/var/lib/ecs/data/metadata/38b3f7e2-5e5a-44c5-8d77-a0e8394d6396/nginx",
"Destination": "/opt/ecs/metadata/fc6ae9c0-a092-42db-85b8-a4e441c8e67c",

But it's still returning exit code 1, what do i miss now?

[buchdag]

Do you have the log output from the letsencrypt-nginx-proxy-companion container ?

[leoddias]

@buchdag i put the env (DEBUG=true) but it didnt make any logs, where can i see them?

[buchdag]

I'm afraid I won't be able to help you much, I don't even know how to check containers logs under ECS 😐

@myoung34 contributed the DOCKER_PROVIDER / ECS code, maybe he can assist you in troubleshooting your setup ?

[myoung34]

DOCKER_PROVIDER = ecs DEBUG=true AND
ECS_ENABLE_CONTAINER_METADATA=true in /etc/ecs/ecs.config (because it was disabled by default)
and i maked a reboot.

DOCKER_PROVIDER = ecs and DEBUG=true need to be environment variables.
putting them into ecs.config is not the same thing. the ecs agent reads from there for values it expects. youll need to add these to your task definition as environment variables like

        "environment": [
          {   
            "name": "DOCKER_PROVIDER",
            "value": "ecs"
          },  
          {   
            "name": "DEBUG",
            "value": "true"
          }   
        ],

Could you put up a working example using the DOCKER_PROVIDER=ecs and say a simple httpd container?

in particular, it is unclear how to get the right network

[myoung34]

in particular, it is unclear how to get the right network

Im not sure what you mean

As for the rest, have you enabled metadata lookup on the ecs cluster? the instances, ecs.config in particular

[flj]

When going through Evert Ramos's examples all the docker containers were in a docker network webproxy. When doing this on standard EC2 machine, it works fine with some basic docker containers (e.g. httpd). For ECS I cannot specify the network it seems, so I guess everything just goes into bridge?

I did not set ecs.config specifically (not sure how to do it from the my machine; and I guess I don't need to ssh in to set it manually), I used the cli to create my cluster

ecs-cli configure --cluster clustecs --region eu-central-1 --default-launch-type EC2 --config-name clustecs
and all it shows in ecs.config is
ECS_CLUSTER=clustecs

How can I set the ECS_ENABLE_CONTAINER_METADATA from the command-line (or from the dashboard if needed)?

[myoung34]

Im not sure, I dont use ecs-cli, but terraform and specify it in the userdata:

  user_data = <<EOF
#!/bin/bash
cat <<EOS >/etc/ecs/ecs.config
ECS_CLUSTER=${var.ecs_cluster_name}
ECS_CONTAINER_STOP_TIMEOUT=${var.ecs_sigterm_timeout}
ECS_AVAILABLE_LOGGING_DRIVERS=["awslogs", "syslog"]
ECS_ENGINE_TASK_CLEANUP_WAIT_DURATION=${var.ecs_task_cleanup_timeout}
ECS_ENABLE_TASK_IAM_ROLE=true
ECS_ENABLE_CONTAINER_METADATA=true
EOS
${var.user_data}
EOF
}

[leoddias]

So, i want to thank everyone, now i have a working solution, using only jwilder + companion containers.
Steps:

1. Set ECS_ENABLE_CONTAINER_METADATA=true in /etc/ecs/ecs.config;
2. Set container's env DOCKER_PROVIDER = ecs
