Deploy Helm Charts

KubeVela's Helm component meets the needs of users to connect to Helm Chart. You can deploy any ready-made Helm chart software package from Helm Repo, Git Repo or OSS bucket through the Helm component, and overwrite its parameters.

Deploy From Helm Repo

In this Application, we hope to deliver a component called redis-comp. It is a chart from the bitnami.

cat <<EOF | vela up -f -
apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: app-delivering-chart
spec:
  components:
    - name: redis-comp
      type: helm
      properties:
        chart: redis-cluster
        version: 6.2.7
        url: https://charts.bitnami.com/bitnami
        repoType: helm
EOF

Please copy the above code block and deploy it directly to the runtime cluster:

application.core.oam.dev/app-delivering-chart created

Finally, we use vela ls to view the application status after successful delivery:

APP                 	COMPONENT 	TYPE      	TRAITS	PHASE  	HEALTHY	STATUS	CREATED-TIME                 
app-delivering-chart	redis-comp	helm      	      	running	healthy	      	2021-08-28 18:48:21 +0800 CST

We also see that the PHASE of the app-delivering-chart APP is running and the STATUS is healthy.

Deploy From OSS bucket

1. (Optional) If your OSS bucket needs identity verification, create a Secret:

$ kubectl create secret generic bucket-secret --from-literal=accesskey=<your-ak> --from-literal=secretkey=<your-sk>
secret/bucket-secret created

1. Example

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: bucket-app
spec:
  components:
    - name: bucket-comp
      type: helm
      properties:
        repoType: oss
        # required if bucket is private
        secretRef: bucket-secret
        chart: ./chart/podinfo-5.1.3.tgz
        url: oss-cn-beijing.aliyuncs.com
        oss:
            bucketName: definition-registry

Deploy From Git Repo

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
   name: app-delivering-chart
spec:
   components:
     - name: terraform-controller
       type: helm
       properties:
          repoType: git
          url: https://github.com/oam-dev/terraform-controller
          chart: ./chart
          git:
          	branch: master
