3. 创建 k8s 集群
本文仅做 PoC 演示，非标准生产环境部署步骤，因此这里使用 kind 创建 k8s 集群。
1 2
kind create cluster kubectl cluster-info
输出：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
[root@shawnyan ~]# kind create cluster Creating cluster "kind" ... ✓ Ensuring node image (kindest/node:v1.29.2) 🖼 ✓ Preparing nodes 📦 ✓ Writing configuration 📜 ✓ Starting control-plane 🕹️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️ ✓ Installing CNI 🔌 ✓ Installing StorageClass 💾 Set kubectl context to "kind-kind" You can now use your cluster with:
kubectl cluster-info --context kind-kind
Thanks for using kind! 😊 [root@shawnyan ~]# kubectl cluster-info --context kind-kind Kubernetes control plane is running at https://127.0.0.1:34967 CoreDNS is running at https://127.0.0.1:34967/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
[root@shawnyan ~]# kbcli playground init Create k3d cluster: kb-playground OK Merge kubeconfig to /root/.kube/config OK Switch current context to k3d-kb-playground OK Write kubeconfig to /root/.kbcli/playground/kubeconfig OK KubeBlocks will be installed to namespace "kb-system" Kubernetes version 1.23.8+k3s1 Kubernetes provider K3S kbcli version 0.8.2 Create CRDs OK Add and update repo kubeblocks OK Install KubeBlocks 0.8.2 OK Wait for addons to be enabled apecloud-mysql OK ... Create cluster mycluster (ClusterDefinition: apecloud-mysql) OK
KubeBlocks playground init SUCCESSFULLY!
Kubernetes cluster "kb-playground" has been created. Cluster "mycluster" has been created. Elapsed time: 5m50s ... [root@shawnyan ~]#
[root@shawnyan ~]# kbcli addon search tidb ADDON VERSION INDEX tidb 0.1.0-alpha.1 kubeblocks [root@shawnyan ~]# [root@shawnyan ~]# kbcli addon install tidb Default addon index "kubeblocks" has been added. addon tidb installed successfully [root@shawnyan ~]# [root@shawnyan ~]# kbcli addon list | egrep 'NAME|tidb' NAME VERSION PROVIDER STATUS AUTO-INSTALL tidb 0.1.0-alpha.1 community Enabled true [root@shawnyan ~]# [root@shawnyan ~]# kbcli addon enable tidb addon.extensions.kubeblocks.io/tidb enabled
2. 创建 TiDB 集群
使用 kbcli cluster 命令管理集群。
创建 TiDB 集群，并查看集群列表。
1 2 3 4 5 6 7
[root@shawnyan ~]# kbcli cluster create tidb-demo --cluster-definition tidb Info: --cluster-version is not specified, ClusterVersion tidb-v7.1.2 is applied by default Cluster tidb-demo created [root@shawnyan ~]# [root@shawnyan ~]# kbcli cluster list NAME NAMESPACE CLUSTER-DEFINITION VERSION TERMINATION-POLICY STATUS CREATED-TIME tidb-demo default tidb tidb-v7.1.2 Delete Running May 10,2024 18:57 UTC+0800
这里可以看到，集群已创建成功，并运行正常。
查看集群定义和版本信息：
1 2 3 4 5 6 7
