Kubernetes, specify network and health check

Question

I'm trying to run Stellar in Kubernetes.

Initially I'm working with the quickstart (stellar/quickstart:latest).

The problem I'm facing is, when specifying the network via an explicit command and args then the livenessProbe and readinessProbe fail.

Probes

When I do NOT specify a command, and arg, it starts fine, using testnet.

However, when I do try to specify the command and arg - so that I can use pubnet - I get the below error:

      containers:
        - name: chain-node
          imagePullPolicy: IfNotPresent
          image: {{ .Values.image }}
          command: ["start"]
          args: ["--pubnet"]

When it works

If I do NOT specify a command and arg, then the container starts, and the probes run as expected.

      containers:
        - name: chain-node
          imagePullPolicy: IfNotPresent
          image: {{ .Values.image }}

Error

Liveness probe failed: OCI runtime exec failed: exec failed: container_linux.go:370: starting container process caused: exec: "stellar-core http-command 'info'": executable file not found in $PATH: unknown

Answer 1

The start command is actually /start (with a slash) and since that is also the images default you can leave it out at all.

  containers:
  - name: chain-node
    image: stellar/quickstart:latest
    args: ["--pubnet"]
