Assume that you have a Chartmuseum container running in AWS Fargate.

Chartmuseum is a repository for helm charts. AWS Fargate is an Amazon service to run containers (“serverless”), being part of ECS (Elastic Container Service).

Problem statement: Add a container healthcheck to the chartmuseum task definition associated with the container.

The official docs suggest using curl:

["CMD-SHELL", "curl -f http://localhost/ || exit 1"]

For Chartmuseum specifically we’re interested in its /health endpoint, as per this reference:

["CMD-SHELL", "curl -f http://localhost/health || exit 1"]

But we’re using port 8080:

["CMD-SHELL", "curl -f http://localhost:8080/health || exit 1"]

If you use this healthcheck for the official chartmuseum image ( it will fail, because the Alpine Linux environment it uses does not contain curl.

A straightforward fix is to use wget instead:

["CMD-SHELL", "wget -q --spider http://localhost:8080/health || exit 1"]

--spider is needed because we do not want to download anything, -q is optional and short for “quiet”.

The /health endpoint merely returns a simple JSON:
