MicroK8S部署网络服务器
MicroK8S deploy webserver
我正在玩 microk8s，我正在尝试部署 nextcloud 以更加熟悉它。但是 nextcloud 的部署很顺利，我在为此设置入口时遇到了一些问题。也许你可以看看我的清单和入口资源，帮我找到问题所在。
这是部署文件：

调用 http://k8s.ip/nextcloud 结果为 503。知道我遗漏了什么吗？
正如我在评论中post编辑的那样：
You are receiving 503 code because you have a missmatch in your Service -> .spec.selector (run: nextcloud-app) and your Deployment -> .spec.selector.matchLabels (app: nextcloud-app). You will need to have them both the same. You can see it also when describing the service (no endpoint).
此特定设置中的问题是 Deployment 中的 matchLabel 与 Service 中的 selector 之间存在不匹配：
Deployment
spec:
replicas: 1
selector:
matchLabels:
app: nextcloud-app # <-- HERE!
Service:
spec:
ports:
- port: 80
targetPort: 8080
selector:
run: nextcloud-app # <-- HERE!
要解决这个问题，您需要让它们都匹配（例如）：
app: nextcloud-app 在 Deployment 和 Service
识别不匹配选择器的一些方法（使用post中的示例）：
- 手动检查
YAML 定义，如上所示
$ kubectl -n nextcloud describe svc nextcloud-service
Name: nextcloud-service
Namespace: nextcloud
Labels: run=nextcloud-app
Annotations: <none>
Selector: run=nextcloud-app
Type: ClusterIP
IP: 10.152.183.189
Port: <unset> 80/TCP
TargetPort: 8080/TCP
Endpoints: <none> # <-- HERE
Session Affinity: None
Events: <none>
以上 describe 显示服务已创建，但没有 endpoints (Pods) 可将流量发送到。
No endpoint could be also related to the fact that Pod is not Ready or is not in Healthy state
$ kubectl get endpoint -n nextcloud
NAME ENDPOINTS AGE
nextcloud-service <none> 1m

我鼓励您查看 nextcloud 的 Helm 图表：

调用 http://k8s.ip/nextcloud 结果为 503。知道我遗漏了什么吗？
正如我在评论中post编辑的那样：
You are receiving 503 code because you have a missmatch in your
Service->.spec.selector(run: nextcloud-app) and yourDeployment->.spec.selector.matchLabels(app: nextcloud-app). You will need to have them both the same. You can see it also when describing the service (no endpoint).
此特定设置中的问题是 Deployment 中的 matchLabel 与 Service 中的 selector 之间存在不匹配：
Deployment
spec:
replicas: 1
selector:
matchLabels:
app: nextcloud-app # <-- HERE!
Service:
spec:
ports:
- port: 80
targetPort: 8080
selector:
run: nextcloud-app # <-- HERE!
要解决这个问题，您需要让它们都匹配（例如）：
app: nextcloud-app在Deployment和Service 中
识别不匹配选择器的一些方法（使用post中的示例）：
- 手动检查
YAML定义，如上所示 $ kubectl -n nextcloud describe svc nextcloud-service
Name: nextcloud-service
Namespace: nextcloud
Labels: run=nextcloud-app
Annotations: <none>
Selector: run=nextcloud-app
Type: ClusterIP
IP: 10.152.183.189
Port: <unset> 80/TCP
TargetPort: 8080/TCP
Endpoints: <none> # <-- HERE
Session Affinity: None
Events: <none>
以上 describe 显示服务已创建，但没有 endpoints (Pods) 可将流量发送到。
No endpoint could be also related to the fact that
Podis notReadyor is not inHealthystate
$ kubectl get endpoint -n nextcloud
NAME ENDPOINTS AGE
nextcloud-service <none> 1m
