Vikunja Helm Chart

Deployes both frontend and backend. Also, you can deploy bitnami's PostgreSQL and Redis as subcharts if you want.

Requirements

Kubernetes >= 1.19
Helm >= 3

Quickstart

Default settings should work for you and if you define ingress settings according to your controller (for both API and Frontend), you will be able to access the frontend. Anyway, it won't have any default credentials. In order to create a user, you have to enable registration and register a new user.

api:
  config:
    service:
      enableregistration: true

Once you have registered, you can disable registration back if you do not need it.

Advanced features

Raw resources

Often happens, that you have to deploy some cloud-specific resources that are not a part of the application chart itself. You have to either create an extra chart for that, or manage them with other tools (kustomize, plain manifests etc.). That is painful. We have a solution. If you want to create anything that is not present in the chart, just add it in raw!

Let's say, you are hosted in GKE and want to use Google-managed TLS certificates. In order to do that, you have to create a ManagedCertificate resource. It can be done this way.

frontend:
  enabled: true
  annotations:
    kubernetes.io/ingress.class: gce
    networking.gke.io/managed-certificates: gmc-example-com
  hosts:
  - host: example.com
    paths:
    - path: /
      pathType: Prefix

raw:
- apiVersion: networking.gke.io/v1
  kind: ManagedCertificate
  metadata:
    name: gmc-example-com
  spec:
    domains:
    - example.com

Or, let's say, you have decided to use Google SQL database instead of self-hosted, and placed credentials in Google Secret Manager. You plan to use ExternalSecrets to get that credentials. These can be easily integrated as well.

# Disable embedded database
postgresqlEnabled: false

api:
  config:
    database:
      # Use PostgreSQL database anyway
      type: postgresql
  envFrom:
  # Bind env variables from the secret
  - name: VIKUNJA_DATABASE_USER
    valueFrom:
      secretKeyRef:
        name: postgresql-credentials
        key: username
  - name: VIKUNJA_DATABASE_PASSWORD
    valueFrom:
      secretKeyRef:
        name: postgresql-credentials
        key: password
  - name: VIKUNJA_DATABASE_HOST
    valueFrom:
      secretKeyRef:
        name: postgresql-credentials
        key: hostname
  - name: VIKUNJA_DATABASE_DATABASE
    valueFrom:
      secretKeyRef:
        name: postgresql-credentials
        key: database

raw:
- apiVersion: external-secrets.io/v1beta1
  kind: SecretStore
  metadata:
    name: gcpsm
  spec:
    refreshInterval: 300
    provider:
      gcpsm:
        projectID: my-google-project-id

- apiVersion: external-secrets.io/v1beta1
  kind: ExternalSecret
  metadata:
    name: postgresql-credentials
  spec:
    secretStoreRef:
      kind: SecretStore
      name: gcpsm
    target:
      deletionPolicy: Delete
    refreshInterval: 5m
    dataFrom:
    - extract:
        key: cloud-sql-credentials

Enjoy!

Contributing

In order to publish the chart, you have to either use curl or helm cm-push.

helm package .
curl --user '<username>:<password>' -X POST --upload-file './<archive>.tgz' https://kolaente.dev/api/packages/vikunja/helm/api/charts

helm package .
helm repo add --username '<username>' --password '<password>' vikunja https://kolaente.dev/api/packages/vikunja/helm
helm cm-push './<archive>.tgz' vikunja

As you can see, you do not have to specify the name of the repository, just the name of the organization.
