Rowan Smith 623893708b feat: add helm var to support RBAC for deploying workspaces in extra namespaces (#19517)
This is a feature to create Role & RoleBinding entries on a per
namespace basis to support deploying workspaces in separate namespace to
where Coder is deployed. The idea behind this is to avoid the creation
of custom RBAC entries or the use of ClusterRoles (in order to maintain
priciple of least privilege).

This is a blink assisted PR.

Example `helm template` without
`coder.serviceAccount.workspaceNamespaces` enabled (existing behaviour
as of current release) is below. Outcome = 1 x SA, 1 x Role, 1 x
RoleBinding, all in the coder (`.Release.Namespace`) namespace.
```
➜  coder git:(feat/helm_namespace_rbac_improvements) ✗ helm template -n coder coder . --set coder.image.tag=v2.25.1

Example `helm template` *with*
`coder.serviceAccount.workspaceNamespaces` enabled is below. Outcome = 1
x SA, 1 x Role, 1 x RoleBinding, all in the coder (`.Release.Namespace`)
namespace PLUS a Role and RoleBinding in the `dev-ws` namespace with
each of the RoleBindings referencing the coder SA in the coder
(`.Release.Namespace`) namespace:

```
➜  coder git:(feat/helm_namespace_rbac_improvements) ✗ helm template -n coder coder . --set coder.image.tag=v2.25.1 --set-json 'coder.serviceAccount.workspaceNamespaces=[{"name":"dev-ws","workspacePerms":true,"enableDeployments":true,"extraRules":[]}]'

Coder Helm Chart

This directory contains the Helm chart used to deploy Coder onto a Kubernetes cluster. It contains the minimum required components to run Coder on Kubernetes, and notably (compared to Coder Classic) does not include a database server.

Getting Started

Warning

: The main branch in this repository does not represent the latest release of Coder. Please reference our installation docs for instructions on a tagged release.

View our docs for detailed installation instructions.

Values

Please refer to values.yaml for available Helm values and their defaults.

A good starting point for your values file is:

coder:
  # You can specify any environment variables you'd like to pass to Coder
  # here. Coder consumes environment variables listed in
  # `coder server --help`, and these environment variables are also passed
  # to the workspace provisioner (so you can consume them in your Terraform
  # templates for auth keys etc.).
  #
  # Please keep in mind that you should not set `CODER_HTTP_ADDRESS`,
  # `CODER_TLS_ENABLE`, `CODER_TLS_CERT_FILE` or `CODER_TLS_KEY_FILE` as
  # they are already set by the Helm chart and will cause conflicts.
  env:
    - name: CODER_ACCESS_URL
      value: "https://coder.example.com"
    - name: CODER_PG_CONNECTION_URL
      valueFrom:
        secretKeyRef:
          # You'll need to create a secret called coder-db-url with your
          # Postgres connection URL like:
          # postgres://coder:password@postgres:5432/coder?sslmode=disable
          name: coder-db-url
          key: url

    # This env enables the Prometheus metrics endpoint.
    - name: CODER_PROMETHEUS_ADDRESS
      value: "0.0.0.0:2112"
    # For production deployments, we recommend configuring your own GitHub
    # OAuth2 provider and disabling the default one.
    - name: CODER_OAUTH2_GITHUB_DEFAULT_PROVIDER_ENABLE
      value: "false"
