重装了k8s集群后，重新安装k8s的仪表板，发现与以前安装不一样的地方。主要是镜像下载的问题，由于网络安全以及国外网站封锁的原因，现在很多镜像按照官方提供的仓库地址都下拉不下来，导致安装失败。我查了好几天，终于找到一个镜像仓库的对照表，并亲自验证，可用（只少目前可用）。下面将对照表和安装文件的修改步骤记录下来，以方便后期同等问题的资料查找。
镜像替换对照表
cr.l5d.io --> I5d.m.daocloud.io
docker.elastic.co --> elastic.m.daocloud.io
docker.io --> docker.m.daocloud.io
gcr.io --> gcr.m.daocloudio
ghcr.io --> ghcr.m.daocloud.io
k8s.gcr.io --> k8s-gcr.m.daocloud.io
registry.k8s.io --> k8s.m.daocloud.io
mcr.microsoft.com --> mcr.m.daocloud.io
nvcr.io --> nvcr.m.daocloud.io
quay.io --> quay.m.daocloud.io
registryjujucharms.com --> jujucharms.m.daocloud.io
rocks.canonical.com --> rocks-canonical.m.daocloud.io
按照官网的安装步骤使用helm安装，先把chart下载下来，我这里使用的是7.0.0版本
部署和访问 Kubernetes 仪表板（Dashboard） | Kubernetes
# 添加 kubernetes-dashboard 仓库
helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/
helm pull kubernetes-dashboard/kubernetes-dashboard --version=7.0.0解压tgz包，修改value.yaml文件
我这里要将pod部署到control-plane节点，所以修改了tolerations值的内容，正常默认pod是部署到work节点的，没有此需求这里不用修改tolerations值的内容
tar -zxvf kubernetes-dashboard-7.0.0.tgz
cd kubernetes-dashboard
vim values.yaml
#image.repository的值，对照上面的镜像替换表，将相应的部分替换就行
比如：
:%s/docker.io/docker.m.daocloud.io/g
#修改容忍污点值和选择节点标签值
:%s/nodeSelector: {}/nodeSelector: {kubernetes-dashboard: master}/g
:%s/tolerations: []/tolerations: [{key: "node-role.kubernetes.io/control-plane", operator: "Exists", effect: "NoSchedule"}]/g
wq
#当然事先要将control-plane节点打上相应标签
kubectl lable nodes k8s70131 kubernetes-dashboard=master
#删除标签命令：kubectl lable nodes k8s70131 kubernetes-dashboard-在dashboard部署中，官方helm安装是部署了5个不同的pod，
#kubectl get pod -n kubernetes-dashboard

#find ./ -name values.yaml
./charts/metrics-server/values.yaml

./charts/kong/charts/postgresql/charts/common/values.yaml
./charts/kong/charts/postgresql/values.yaml

./charts/cert-manager/values.yaml
./values.yaml
#这里修改的主要是image.repository的值
#在我的需求里还要修改./charts/kong/values.yaml文件中的污点容忍和节点选择标签的值修改完毕后按照官网的命令执行部署
#在kubernetes-dashboard目录下
helm upgrade --install kubernetes-dashboard ./ --create-namespace --namespace kubernetes-dashboard
#显示如下执行成功kubectl get all -n kubernetes-dashboard
