Adding tracepoints to the Concourse worker's healthcheck on k8s

install go

Make sure go is installed on your worker -- this should be possible to do by running something like

kubectl -n <namespace> exec <worker pod> -- apt-get install -y golang-go

Suppose the following resource in pipeline p is slow to check:

- name: image
  type: docker-image
  source:
    repository: artifactory.internal/concourse-docker/cf-mgmt
    tag: '05.12.2020'
    insecure_registries: 
 - artifactory.internal

We're releasing! Why?

1. We felt like it - we knew this was coming
   1. sick new features => major/minor
      • We've gotten pretty good at this 👍 usually we just hit shipit on the main pipeline and profit. But we also need to create some branches on a few repos and a patch pipeline in most cases.
      • Usually some engineer is pushing for this (I want to see my pet feature in the hands of users and bask in their admiration)
2. fixing something embarrassing => patch latest minor
