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_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 variable controls whether or not to auto-import the "kubernetes"
    # template on first startup. This will not work unless
    # coder.serviceAccount.workspacePerms is true.
    - name: CODER_TEMPLATE_AUTOIMPORT
      value: "kubernetes"
