Invalid service name on Kubernetes

agent

Describe the bug

Woodpecker generates a prefix for kubernetes resources like 0-2156149869907855750. This can be used as prefix for a pvc name but it's an invalid prefix for services because "The name of a Service object must be a valid RFC1035 label name" (source).

The ci config:

services:
  docker:
    image: docker:22.06-rc-dind

pipeline:
  build:
    image: docker:22.06-rc-dind
    commands:
      - printenv | sort

The error:

default/woodpecker-woodpecker-agent-f485dddcf-bhlqb[woodpecker-agent]: {
  "level": "error",
  "error": "rpc error: code = Unknown desc = Proc finished with exitcode 1, Service \"0-2891002623454858384-services-0\" is invalid: [metadata.name: Invalid value: \"0-2891002623454858384-services-0\": a DNS-1035 label must consist of lower case alphanumeric characters or '-', start with an alphabetic character, and end with an alphanumeric character (e.g. 'my-name',  or 'abc-123', regex used for validation is '[a-z]([-a-z0-9]*[a-z0-9])?'), spec.ports: Required value]",
