Labels and Annotations

labels and annotations traits allow us to mark annotations and labels on Pod for workload.

Note: labels and annotations traits are hidden by default in VelaUX, you can use them in CLI.

Specification#

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

They're all string Key-Value pairs.

How to use#

# 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"

Then the labels and annotations will mark on pods.
