APM-server docker image does not support curl, preventing proper health test

Gil_Zigelman · May 10, 2024, 3:58pm

APM Server version docker image: 8.13.4

The docker image does not support curl command.
I would like to use curl to detect whether apm-server is healthy for dependent services.

Steps to reproduce**:

docker run -it elastic/apm-server:8.13.4
2.docker ps --> look for the id if the apm-server container
3.docker exec -it [CONTAINER_ID] /bin/bash
curl
Observe error message: "bash: curl: command not found"

Is there some alternative way to health check the apm-server container?

Thank you!

A couple of stop-gap options:

you could manually craft an HTTP request with bash: How to execute healthcheck without curl · Issue #58 · dart-lang/dart-docker · GitHub
build a derivative image which installs curl

I think it would probably make sense for us to add an apm-server sub command (apm-server test server or something like that...) for performing a healthcheck, and defining that in the Docker image.
