Description

Adding a health check to your ECS task definitions ensures that it is still operational and gives you more control in monitoring the health of your tasks. It also enables the host to kill and reschedule tasks that are no longer operational.

How to fix?

In the container_definitions attribute, set healthcheck to a command that determines whether the container is healthy.

Example configuration:

resource "aws_ecs_task_definition" "valid_container_healthcheck" {
  family = "valid_container_healthcheck"

  container_definitions = <<EOF
[
  {
    "name": "valid_container_healthcheck",
    "image": "hello-world",
    "memory": 128,
    "healthcheck": {
      "command": ["CMD-SHELL", "echo 'healthy' || exit 1"]
    }
  }
]
EOF
