Container doesn't contain curl or wget needed to use healthcheck on Fargate

[NeilJed]

The default Fargate configuration enables the healthcheck endpoint and I want to use this as part of my task definition to ensure the Otel Collector sidecar is in service.

However, as the checkis run internally from within the container, this can't be done as it doesn't ship with curl, wget or another shell tool able to make a query to the endpoint and return a status code.

I think the container needs one of these two to enable healtchecks, at least on Fargate, to work.

Hi, curl is available in the agent bundle at /usr/lib/splunk-otel-collector/agent-bundle/bin/curl though this isn't a guaranteed stable location (you will need to set the entrypoint to bash). It may be preferable for you to use the collector image as a partial base and provide your own utilities in a custom image.

TBH I'd rather avoid having to build and maintain our own custom image just to add curl to execute a healthcheck ☹️

How difficult would it be to make the curl location stable at least? I think providing a reliable means of performing a healthcheck on the container seems like a fairly important feature?

So I guess container based healtchecks are dead then?
