add curl to the dockerfile

I had issues with the probes

 Warning  Unhealthy  2m16s (x6 over 3m36s)  kubelet            Liveness probe failed: dial tcp 192.168.158.111:8081: connect: connection refused
  Normal   Killing    2m16s (x2 over 3m16s)  kubelet            Container akhq failed liveness probe, will be restarted
  Warning  Unhealthy  2m12s (x8 over 3m42s)  kubelet            Readiness probe failed: Get "http://192.168.158.111:8081/health": dial tcp 192.168.158.111:8081: connect: connection refused

so I wanted to connect into the pod to try to call manually the URL so see what was the values returned, but wget and curl are not available in the dockerfile.

and we don't have root access, so I couldn't installed it.

for now, I just put in comments the probes and it works fine.

Sound a nice addition, just drop a PR on the docker file and I will merge !
(just for information I change the probe endpoint port on last version, and the helm charts reflect this change, in case you are using an old akhq version)

Hey @tchiotludo , this is very bad decision, curl adds a lot of vulnerabilities for free. It brings more problem than solves.

Thats just about curl, and there are a lot of dependencies that curl uses.

@survivant I advise you to modify pod and add another container with curl for debug purposes:

1. Add a sidecar container:
cat <<EOF > patch-file.yaml
spec:
  template:
    spec:
      shareProcessNamespace: true
      securityContext:
        runAsUser: 0
        fsGroup: 0
      containers:
      - name: akhq
      - name: debug
        image: alpine/curl
        command: ["/bin/sh"]
        args: ["-c", "tail -f /dev/null"]
        securityContext:
          capabilities:
            add:
            - SYS_PTRACE

kubectl patch deployment -connect --patch "$(cat patch-file.yaml)"

To summarise: you don't need curl in the image at all.
