Kubeapps 安装测试

按照官方提供的安装方式执行一遍

官方文档

https://github.com/kubeapps/kubeapps/blob/master/docs/user/getting-started.md

helm repo add bitnami https://charts.bitnami.com/bitnami
helm install --name kubeapps --namespace kubeapps bitnami/kubeapps

直接执行这两步后得到提醒消息

NOTES:
** Please be patient while the chart is being deployed **

Tip:

  Watch the deployment status using the command: kubectl get pods -w --namespace kubeapps

Kubeapps can be accessed via port 80 on the following DNS name from within your cluster:

   kubeapps.kubeapps.svc.cluster.local

To access Kubeapps from outside your K8s cluster, follow the steps below:

1. Get the Kubeapps URL by running these commands:
   echo "Kubeapps URL: http://127.0.0.1:8080"
   export POD_NAME=$(kubectl get pods --namespace kubeapps -l "app=kubeapps" -o jsonpath="{.items[0].metadata.name}")
   kubectl port-forward --namespace kubeapps $POD_NAME 8080:8080

2. Open a browser and access Kubeapps using the obtained URL.

kubectl get pods -w --namespace kubeapps

有一个部署的时候没有拉到image报错

Failed to pull image "docker.io/bitnami/kubeapps-dashboard:1.4.1": rpc error: code = Unknown desc = context canceled

查看所有deploy

kubectl get deploy --namespace kubeapps

查看dashboard 描述

kubectl describe deploy kubeapps-internal-dashboard --namespace kubeapps

如何重新部署这个失败的?

使用helm del --purge kubeapps 删除重新部署还是拉不了docker image

在拉不了的节点手工拉取, 卡在 Pulling fs layer

docker pull docker.io/bitnami/kubeapps-dashboard:1.4.1  

1.4.1: Pulling from bitnami/kubeapps-dashboard
a905bcb05a87: Already exists 
2e4e67ffeb9c: Pulling fs layer

但是第一个节点是可以pull 下来的

从A节点移动到B节点

A节点执行

docker save -o kubeapps-dashboard.tar bitnami/kubeapps-dashboard

复制文件 kubeapps-dashboard.tar 到B节点

scp kubeapps-dashboard.tar node1:~

在B节点执行

加载image

cd ~

docker load -i kubeapps-dashboard.tar

重装后都启动来了, 无法访问应用, 主要还是对网络映射理解不清楚

照着提醒的方法执行, 也卡在那里不动

1. Get the Kubeapps URL by running these commands:
   echo "Kubeapps URL: http://127.0.0.1:8080"
   export POD_NAME=$(kubectl get pods --namespace kubeapps -l "app=kubeapps" -o jsonpath="{.items[0].metadata.name}")
   kubectl port-forward --namespace kubeapps $POD_NAME 8080:8080

下面开始寻找办法

kubectl get pods $POD_NAME --namespace kubeapps -o yaml |grep containerPort

8080端口是存在的

kubectl port-forward --namespace kubeapps $POD_NAME 8080:8080

看起来这个是只能让 127.0.0.1 进行访问, 外网无法访问呀
