Although pkg.go.dev has been opensourced a few years ago, self-hosting a fully featured version of pkgsite for private packages is still a cumbersome process.

This repository provides a Helm chart to:

1. Deploy the pkgsite frontend.
2. Deploy, migrate and seed its PostgreSQL database, powered by the bitnami/postgresql Chart.
3. Optionally deploy a Redis cluster, used by the frontend to cache rendered pages. Powered by the bitnami/redis Chart.
4. Optionally deploy an athens-proxy instance, in order to provide access to private go modules.

• Installing
• Getting started
• Uninstalling
• Exposing the service
• Advanced configuration
  • Seeded packages
  • Deployment settings
  • PostgreSQL
  • Redis
  • athens-proxy

helm repo add pkgsite https://cezarguimaraes.github.io/pkgsite
helm install pkgsite pkgsite/pkgsite

These steps will walk you through setting up a fully featured pkgsite deployment, including a go module proxy able to retrieve private Go packages hosted on Github.

1. Create a namespace to contain pkgsite resources.

   kubectl create namespace pkgsite

2. (Optional) Configure the private go modules proxy

   1. Create a secret to store a GITHUB_TOKEN

      kubectl create secret -n pkgsite generic github-token --from-literal=token=$GITHUB_TOKEN

   2. Create a values.yaml file to configure the proxy:

      athens-proxy:
        enabled: true
      
        downloadMode: |
          downloadURL = "https://proxy.golang.org"
      
          mode = "redirect"
      
          download "github.com/YOURORGANIZATION/*" {
            mode = "sync"
          }
      
        configEnvVars:
          - name: ATHENS_GONOSUM_PATTERNS
            value: github.com/YOURORGANIZATION/*
          - name: ATHENS_GITHUB_TOKEN
            valueFrom:
              # this secret is expected to exist. Example:
              # kubectl create secret generic github-token --from-literal=token=$GITHUB_TOKEN
              secretKeyRef:
                name: github-token
                key: token
          - name: ATHENS_DOWNLOAD_MODE
            valueFrom:
              # this configMap is created by setting athens-proxy.downloadMode
              configMapKeyRef:
                name: athens-config
                key: download.hcl

      Note the .athens-proxy.downloadMode property. This example configures athens-proxy to serve private packages from github.com/YOURORGANIZATION/*, while redirecting any other package to Go's default module mirror for improved performance and reduced costs.

3. Install the chart

   1. Using the values.yaml file created on the previous step:

      helm install pkgsite pkgsite/pkgsite -f values.yaml -n pkgsite

   This can take a few minutes as the seed-db post-hook-install seeds the pkgsite's database.

4. Verify deployment status

   kubectl get pod -n pkgsite
   NAME                      READY   STATUS      RESTARTS   AGE
   pkgsite-86566fc8b-hfzbs   1/1     Running     0          9m48s
   pkgsite-postgresql-0      1/1     Running     0          9m48s
   pkgsite-redis-master-0    1/1     Running     0          9m48s
   pkgsite-setup-db-snxmb    0/1     Completed   0          9m36s

5. Browse your docs locally:

   kubectl port-forward svc/pkgsite -n pkgsite 8080

1. Uninstall the release

   helm uninstall pkgsite

2. Cleanup Persistent Volume Claims

   kukectl delete pvc -l app.kubernetes.io/instance=pkgsite

This step will vary according to your cluster's networking. Some options are:

• Update the serviceType to LoadBalancer
• Enable and configure an Ingress resource
• Configure an ingress using custom networking solutions such as Istio or Consul. Refer to their documentation for instructions.

⚠️ Take care to not expose private go modules documentation to the public internet.

All YAML snippets in this section should be included in your custom values.yaml file.

You can change the list of packages that are seeded when the chart is installed:

seed:
  packages:
  - std@latest
  - golang.org/x/tools@latest
  - github.com/YOURORGANIZATION/YOURPACKAGE@all

Note you can seed all versions of a package, including std. It can, however, take a long time. Seeding packages is not necessary: users can request that any package be fetched by navigating to pkgsite.domain/<import-path>[@version].

Find the complete list of deployment settings in the default values.yaml file.

Find the complete list of PostgreSQL settings in the chart's ArtifactHub page. Prefix parameters by postgresql:

postgresql:
  image:
    registry: my-private-container-registry.io

Find the complete list of Redis settings in the chart's ArtifactHub page. Prefix parameters by redis:

redis:
  architecture: replication

Find the complete list of athens-proxy settings in the chart's Github Repository. Prefix parameters by athens-proxy:

athens-proxy:
  storage:
    type: disk
    disk:
      storageRoot: "/var/lib/athens"
      persistence:
        enabled: true
        accessMode: ReadWriteOnce
        size: 4Gi
