注意手工处理一下kube-scheduler镜像，将其移动到默认库中。并同时修改TidbOperator的values.yaml:

nerdctl tag harbor.dubhe:30002/k8s.gcr.io/kube-scheduler:v1.24.13 harbor.dubhe:30002/library/kube-scheduler:v1.24.13
nerdctl push harbor.dubhe:30002/library/kube-scheduler:v1.24.13

使用Helm安装tidb-operator

wget http://charts.pingcap.org/tidb-operator-v1.5.0-beta.1.tgz # 下载HelmRepo
tar -zxvf tidb-operator-v1.5.0-beta.1.tgz

helm install tidb-operator ./tidb-operator --namespace=tidb-admin --create-namespace

部署

yaml示例:
https://github.com/pingcap/tidb-operator/blob/master/examples/advanced/tidb-cluster.yaml

# 创建CRD
kubectl create -f ./crd.yaml

# 修改tidb-cluster.yaml
name: tidb-dubhe
namespace: default  # 注释掉
requests:  # 限制CPU/MEM，可选
storageClassName:  # 可以默认不填或写成"local-path"
externalTrafficPolicy: # Local改为Cluster，可选
mysqlNodePort: 30550 # 取消注释

# 部署tidb
kubectl create namespace tidb
kubectl apply -f tidb-cluster.yaml -n tidb

初始化

yaml示例:
https://github.com/pingcap/tidb-operator/blob/master/manifests/initializer/tidb-initializer.yaml

# 修改tidb-initializer.yaml
apiVersion: pingcap.com/v1alpha1
kind: TidbInitializer
metadata:
  name: tidb-dubhe-init
  # namespace: demo
spec:
  image: tnir/mysqlclient
  cluster:
    # namespace: demo
    name: tidb-dubhe
  initSql: |-
    create database app;
  passwordSecret: tidb-secret

# 创建secret
kubectl create secret generic tidb-secret --from-literal=root=yourpass --namespace=tidb

# 初始化tidb
kubectl apply -f tidb-initializer.yaml -n tidb

# 访问tidb
kubectl get svc -n tidb
mysql://10.193.35.11:300550
root/yourpass

安装monitoring

yaml示例:

kubectl apply -f tidb-monitor.yaml -n tidb

# Console
http://10.193.35.11:30552

安装dashboard

kubectl apply -f tidb-dashboard.yaml -n tidb
kubectl apply -f tidb-ng-monitoring.yaml -n tidb

# Console
http://10.193.35.11:30551/dashboard
