资源模板

KubeVela 可以以资源模板的方式直接部署任何 Kubernetes 对象。

如何使用#

比如一个 Job。

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
name: app-raw
spec:
components:
- name: myjob
type: k8s-objects
properties:
objects:
- apiVersion: batch/v1
kind: Job
metadata:
name: pi
spec:
template:
spec:
containers:
- name: pi
image: perl
command: ["perl", "-Mbignum=bpi", "-wle", "print bpi(2000)"]
restartPolicy: Never
backoffLimit: 4

也支持多个资源,但是要把你的主要工作负载放在第一个,KubeVela 的 traits 只会对第一个位置的 Kubernetes 对象生效。

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
name: app-stateful-service
spec:
components:
- name: my-sts
type: k8s-objects
properties:
objects:
- apiVersion: apps/v1
kind: StatefulSet
metadata:
name: web
spec:
selector:
matchLabels:
app: nginx # has to match .spec.template.metadata.labels
serviceName: "nginx"
replicas: 3 # by default is 1
template:
metadata:
labels:
app: nginx # has to match .spec.selector.matchLabels
spec:
terminationGracePeriodSeconds: 10
containers:
- name: nginx
image: k8s.gcr.io/nginx-slim:0.8
ports:
- containerPort: 80
name: web
volumeMounts:
- name: www
mountPath: /usr/share/nginx/html
volumeClaimTemplates:
- metadata:
name: www
spec:
accessModes: [ "ReadWriteOnce" ]
storageClassName: "my-storage-class"
resources:
requests:
storage: 1Gi
- apiVersion: v1
kind: Service
metadata:
name: nginx
labels:
app: nginx
spec:
ports:
- port: 80
name: web
clusterIP: None
