标签管理

labelsannotations 运维特征,允许你将标签和注释附加到组件。通过标签和注释,我们在实现业务逻辑时,能十分灵活的根据它们来对应地调用组件。

字段说明#

给 Pod 打注解:

$ vela show annotations
# Properties
+-----------+-------------+-------------------+----------+---------+
| NAME | DESCRIPTION | TYPE | REQUIRED | DEFAULT |
+-----------+-------------+-------------------+----------+---------+
| - | | map[string]string | true | |
+-----------+-------------+-------------------+----------+---------+

给 Pod 打标签:

$ vela show labels
# Properties
+-----------+-------------+-------------------+----------+---------+
| NAME | DESCRIPTION | TYPE | REQUIRED | DEFAULT |
+-----------+-------------+-------------------+----------+---------+
| - | | map[string]string | true | |
+-----------+-------------+-------------------+----------+---------+

字段类型均是字符串键值对。

如何使用#

首先,我们准备一个应用部署计划 YAML 如下:

# myapp.yaml
apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
name: myapp
spec:
components:
- name: express-server
type: webservice
properties:
image: crccheck/hello-world
port: 8000
traits:
- type: labels
properties:
"release": "stable"
- type: annotations
properties:
"description": "web application"

最终标签和注解为打到工作负载底层的 Pod 资源上。
