存储管理

本小节会介绍,如何为应用部署计划的一个待交付组件,管理存储。我们使用运维特征里的 storage 来完成开发。

如何使用#

storage 可以帮助我们创建并管理 pvcemptyDirsecretconfigMap 等类型的存储。对于 secretconfigMap 类的存储,还支持绑定到 env 当中。

如果你不希望自动创建这些资源,可以将 mountOnly 字段设置为 true。

# sample.yaml
apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
name: storage-app
spec:
components:
- name: express-server
type: webservice
properties:
image: crccheck/hello-world
ports:
- port: 8000
traits:
- type: storage
properties:
# PVC type storage
pvc:
- name: test1
mountPath: /test/mount/pvc
# EmptyDir type storage
emptyDir:
- name: test1
mountPath: /test/mount/emptydir
# ConfigMap type storage
configMap:
- name: test1
mountPath: /test/mount/cm
# Mount ConfigMap to Env
mountToEnv:
envName: TEST_ENV
configMapKey: key1
data:
key1: value1
key2: value2
# Secret type storage
secret:
- name: test1
mountPath: /test/mount/secret
# Mount Secret to Env
mountToEnv:
envName: TEST_SECRET
secretKey: key1
data:
key1: dmFsdWUx
key2: dmFsdWUy
