ECS healthcheck

Image with binary to run healthchecks over HTTP. Meant to be used by images running on ECS

Usage

Add the healthcheck binary to your own image with something like this:

# This healthcheck image
FROM imageUrl:imageTag as healthcheck

# The image with your app in it
FROM docker-image-with-my-app

# Add health check binary to the final image
COPY --from=healthcheck /healthcheck /

ENTRYPOINT ["/app/example"]

Then use it as part of your container_definition:

...
  healthCheck : {
    command : [
      "CMD",
      "/healthcheck"
    ]
  }
...

By default, it'll probe /status. To use a different path and/or port, pass it a -path argument. E.g.

  healthCheck : {
    command : [
      "CMD",
      "/healthcheck",
      "-path=:8080/my-status-path"
    ]
  }
