问题描述
我正在尝试部署我的应用程序,但是我正在添加的traefik标签出现以下yaml错误,以便Traefik可以检测到该应用程序。
$ kubectl apply -f example-app.yml
The ReplicationController "example-app" is invalid:
* metadata.labels: Invalid value: "Host(`mydomain.com`)": a valid label must be an empty string or consist of alphanumeric characters,'-','_' or '.',and must start and end with an alphanumeric character (e.g. 'MyValue',or 'my_value',or '12345',regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?')
我的示例-app.yml:
apiVersion: v1
kind: ReplicationController
metadata:
namespace: example
name: example-app
labels:
example-component: "example-app"
traefik.enable: "true"
traefik.http.routers.example-app.rule: "Host(`mydomain.com`)"
traefik.http.routers.example-app.entrypoints: "web"
我也尝试过:
- "example-component=example-app"
- "traefik.http.routers.example-app.rule=Host(mydomain.com)"
- "traefik.http.routers.example-app.entrypoints=web"
- "traefik.enable=true"
但得到:
invalid type for io.k8s.apimachinery.pkg.apis.meta.v1.ObjectMeta.labels: got "array",expected "map"];
