Deploy From OSS bucket

KubeVela's kustomize component meets the needs of users to directly connect Yaml files and folders as component products. No matter whether your Yaml file/folder is stored in a Git Repo or an OSS bucket, KubeVela can read and deliver it.

Let's take the YAML folder component from the OSS bucket registry as an example to explain the usage. In the Application this time, I hope to deliver a component named bucket-comp. The deployment file corresponding to the component is stored in the cloud storage OSS bucket, and the corresponding bucket name is definition-registry. kustomize.yaml comes from this address of oss-cn-beijing.aliyuncs.com and the path is ./app/prod/.

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

2. Deploy it:

cat <<EOF | vela up -f -
apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: bucket-app
spec:
  components:
    - name: bucket-comp
      type: kustomize
      properties:
        repoType: oss
        # If the bucket is private, you will need to provide
        secretRef: bucket-secret
        url: oss-cn-beijing.aliyuncs.com
        oss:
          bucketName: definition-registry
        path: ./app/prod/
EOF

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

application.core.oam.dev/bucket-app created

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

vela ls
APP                 	COMPONENT  	TYPE      	TRAITS	PHASE  	HEALTHY	STATUS	CREATED-TIME                 
bucket-app          	bucket-comp	kustomize 	      	running	healthy	      	2021-08-28 18:53:14 +0800 CST

The PHASE of the app is running, and the STATUS is healthy. Successful application deployment!

Deploy From Git Repo

How-to

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: git-app
spec:
  components:
    - name: git-comp
      type: kustomize

Override Kustomize

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: bucket-app
spec:
  components:
    - name: bucket-comp
      type: kustomize
      properties:
        # ...omitted for brevity
        path: ./app/
     

Watch Image Registry

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: image-app
spec:
  components:
    - name: image
      type: kustomize
      properties:
        imageRepository:
          image: <your image>
          secretRef: imagesecret
          filterTags:
            pattern: '^master-[a-f0-9]+-(?P<ts>[0-9]+)'
            extract: '$ts'
          policy:
            numerical:
              order: asc
          commitMessage: "Image: {{range .Updated.Images}}{{println .}}{{end}}"
