How to configure all the command options as k8s ConfigMap?

    spec:
      containers:
        - name: geth
          image: ethereum/client-go:v1.14.12
          imagePullPolicy: Always
          args:
            - --holesky
            - --http
            - --http.addr=0.0.0.0
            - --http.vhosts=geth
            - --ws
            - --ws.addr=0.0.0.0
            - --authrpc.jwtsecret=/tmp/jwtsecret
            - --datadir=/data

I would love these to be organized into ConfigMap instead of in the STS manifest file. Actually, if you have a sample .toml file used with --config for all the options defined in https://github.com/ethpandaops/ethereum-helm-charts/blob/master/charts/geth/values.yaml that will be helpful.

Geth allows setting most of its configuration also via env vars . Check out geth --help to know each individual ENV var that maps to a flag. For example --http.addr maps to GETH_HTTP_ADDR.

So with that, you could have a configmap with env vars defined. And then just use envFromthe configmap. example:

apiVersion: v1
kind: ConfigMap
metadata:
  name: geth-config
data:
  GETH_HTTP_ADDR: "0.0.0.0"
  ...
  more flags..

apiVersion: v1
kind: Pod
metadata:
  name: geth
spec:
  containers:
    - name: geth
      image: ethereum/client-go:v1.14.12
      envFrom:
      - configMapRef:
          name: geth-config
  restartPolicy: Never

Where can I find more information on the ports, which ports are used for what purpose?

# -- P2P Port
p2pPort: 30303

# -- HTTP Port
httpPort: 8545

# -- WS Port
wsPort: 8545

# -- Engine Port (Auth Port)
authPort: 8551
