1、命名空间

k create ns ti
k create namespace tidb-admin
k create namespace tidb-cluster

alias k='kubectl'
alias ti='k -n tidb'
alias tia='k -n tidb-admin'
alias tic='k -n tidb-cluster'

2、 Helm安装 tidb-operator

helm repo add pingcap https://charts.pingcap.org/
helm repo update
helm repo list
helm install --namespace tidb-admin tidb-operator pingcap/tidb-operator --version v1.4.4

tic api-resources | grep pingcap
statefulsets                       asts           apps.pingcap.com               true         StatefulSet
backups                            bk             pingcap.com                    true         Backup
backupschedules                    bks            pingcap.com                    true         BackupSchedule
restores                           rt             pingcap.com                    true         Restore
tidbclusterautoscalers             ta             pingcap.com                    true         TidbClusterAutoScaler
tidbclusters                       tc             pingcap.com                    true         TidbCluster
tidbinitializers                   ti             pingcap.com                    true         TidbInitializer
tidbmonitors                       tm             pingcap.com                    true         TidbMonitor

似乎缺少了TidbDashboard！

3、安装 TiDB Cluster

问题1：storageClassName
csi-localpv

问题2：Failed to pull image “k8s.gcr.io/kube-scheduler:v1.18.17”
k8smaster.qfusion.irds/irds/kube-scheduler:v1.18.17

在这里插入图片描述

apiVersion: pingcap.com/v1alpha1

4、访问

kubectl port-forward -n tidb-cluster svc/dba-tidb 14000:4000 > pf14000.out &
mysql --comments -h 127.0.0.1 -P 14000 -u root
select tidb_version()\G

在这里插入图片描述

port-forward

5、TiDB Dashboard

apiVersion: pingcap.com/v1alpha1
kind: TidbDashboard
metadata:name: basic
spec:baseImage: pingcap/tidb-dashboardversion: latest## tidb cluster to be monitored## ** now only support monitoring one tidb cluster **clusters:- name: dba## describes the compute resource requirements and limits.## Ref: https://kubernetes.io/docs/concepts/configuration/manage-compute-resources-container/requests:storage: 10GistorageClassName: "csi-localpv"

密码是TiDB的root密码，默认是“空”
