budibase

Budibase is an open source low-code platform, helping thousands of teams build apps for their workplace in minutes.

Prerequisites

  • helm v3 or above
  • Kubernetes 1.4+
  • A storage controller (if you want to use persistent storage)
  • An ingress controller (if you want to define an Ingress resource)
  • metrics-server (if you want to make use of horizontal pod autoscaling)

Chart dependencies

This chart depends on the official Apache CouchDB chart. You can see its documentation here: https://github.com/apache/couchdb-helm/tree/couchdb-4.3.0/couchdb.

Upgrading

2.x to 3.0.0

We made a number of breaking changes in this release to make the chart more idiomatic and easier to use.

  1. We no longer bundle ingress-nginx. If you were relying on this to supply an ingress controller to your cluster, you will now need to deploy that separately. You'll find guidance for that here: https://kubernetes.github.io/ingress-nginx/.
  2. We've upgraded the version of the CouchDB chart we use from 3.3.4 to 4.3.0. The primary motivation for this was to align the CouchDB chart used with the CouchDB version used, which has also updated from 3.1.1 to 3.2.1. Additionally, we're moving away from the official CouchDB to one we're building ourselves.
  3. We've separated out the supplied AWS ALB ingress resource for those deploying into EKS. Where previously you enabled this by setting ingress.enabled: false and ingress.aws: true, you now set awsAlbIngress.enabled: true and all configuration for it is under awsAlbIngress.
  4. The HorizontalPodAutoscaler that was configured at hpa.enabled: true has been split into 3 separate HPAs, one for each of apps, worker, and proxy. They are configured at services.{apps,worker,proxy}.autoscaling.

Installing

To install the chart from our repository:

$ helm repo add budibase https://budibase.github.io/budibase/
$ helm repo update
$ helm install --create-namespace --namespace budibase budibase budibase/budibase

To install the chart from this repo:

$ git clone git@github.com:budibase/budibase.git
$ cd budibase/charts/budibase
$ helm install --create-namespace --namespace budibase budibase .

Example minimal configuration

Here's an example values.yaml that would get a Budibase instance running in a home cluster using an nginx ingress controller and NFS as cluster storage (basically one of our staff's homelabs).

ingress:
  enabled: true
  className: "nginx"
  hosts:
    - host: budibase.local # set this to whatever DNS name you'd use
      paths:
        - backend:
            service:
              name: proxy-service
              port:
                number: 10000
          path: /
          pathType: Prefix

couchdb:
  persistentVolume:
    enabled: true
    storageClass: "nfs-client"
  adminPassword: admin

services:
  objectStore:
    storageClass: "nfs-client"
  redis:
    storageClass: "nfs-client"

If you wanted to use this when bringing up Budibase in your own cluster, you could save it to your hard disk and run the following:

$ helm install --create-namespace --namespace budibase budibase . -f values.yaml
