VMware Tanzu Community Edition 是一个功能齐全、易于管理的 Kubernetes 平台，供学习者和用户使用。它是一个免费的、社区支持的、开源的 VMware Tanzu 发行版，可以在几分钟内在您的本地工作站或您喜欢的云上安装和配置。

Linux Local Bootstrap Machine Prerequisites

1、检查cgroup

linux-mint-002@linux-mint-002:~/tanzu$ sudo docker info | grep -i cgroup
 Cgroup Driver: cgroupfs
 Cgroup Version: 1

如果 cgroups v2,需要设置 system.unified_cgroup_hierarchy=0

2、下载tanzu CLI

linux-mint-002@linux-mint-002:~/tanzu$ wget http://192.168.100.18:1234/tce-linux-amd64-v0.9.1.tar.gz
linux-mint-002@linux-mint-002:~/tanzu$ tar -zxf tce-linux-amd64-v0.9.1.tar.gz
linux-mint-002@linux-mint-002:~/tanzu$ ls
tce-linux-amd64-v0.9.1  tce-linux-amd64-v0.9.1.tar.gz
linux-mint-002@linux-mint-002:~/tanzu$ cd tce-linux-amd64-v0.9.1/
linux-mint-002@linux-mint-002:~/tanzu/tce-linux-amd64-v0.9.1$ ls
bin  install.sh  uninstall.sh

3、运行install.sh安装

linux-mint-002@linux-mint-002:~/tanzu/tce-linux-amd64-v0.9.1$ ./install.sh

Installation complete!

4、下载kubectl

curl -LO https://dl.k8s.io/release/v1.22.0/bin/linux/amd64/kubectl
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

5、创建集群

需要你的资源满足如下要求

6 GB of RAM
15 GB of local machine disk storage for images
4 CPUs

Local Docker Bootstrapping

1、初始化Tanzu 安装接口

linux-mint-002@linux-mint-002:~/tanzu/tce-linux-amd64-v0.9.1$ tanzu management-cluster create --ui -b 192.168.100.66:8080

Validating the pre-requisites...
Serving kickstart UI at http://192.168.100.66:8080
unable to open browser: exit status 3

2、现在可以打开链接，通过浏览器安装配置集群了

3、首先我们部署一个管理集群到docker环境

4、最后点击部署，即可开始创建一个管理集群，也可以用最底下的命令行执行

5、等待部署完成，验证管理集群是否正常

linux-mint-002@linux-mint-002:~/tanzu$   tanzu management-cluster get
  NAME   NAMESPACE   STATUS   CONTROLPLANE  WORKERS  KUBERNETES        ROLES
  tanzu  tkg-system  running  1/1           1/1      v1.21.2+vmware.1  management

Details:

NAME                                                      READY  SEVERITY  REASON  SINCE  MESSAGE
/tanzu                                                    True                     6d23h
├─ClusterInfrastructure - DockerCluster/tanzu             True                     6d23h
├─ControlPlane - KubeadmControlPlane/tanzu-control-plane  True                     6d23h
│ └─Machine/tanzu-control-plane-v9jxw                     True                     6d23h
└─Workers
  └─MachineDeployment/tanzu-md-0
    └─Machine/tanzu-md-0-567d7cf787-wkphp                 True                     6d23h

Providers:

  NAMESPACE                          NAME                   TYPE                    PROVIDERNAME  VERSION  WATCHNAMESPACE
  capd-system                        infrastructure-docker  InfrastructureProvider  docker        v0.3.23
  capi-kubeadm-bootstrap-system      bootstrap-kubeadm      BootstrapProvider       kubeadm       v0.3.23
  capi-kubeadm-control-plane-system  control-plane-kubeadm  ControlPlaneProvider    kubeadm       v0.3.23
  capi-system                        cluster-api            CoreProvider            cluster-api   v0.3.23

6、获取管理集群的kubeconfig

linux-mint-002@linux-mint-002:~/tanzu$ tanzu management-cluster kubeconfig get tanzu --admin

然后就可以执行kubectl操作管理集群了

linux-mint-002@linux-mint-002:~/tanzu$  kubectl  get no
NAME                          STATUS   ROLES                  AGE     VERSION
tanzu-control-plane-v9jxw     Ready    control-plane,master   6d23h   v1.21.2+vmware.1-360497810732255795
tanzu-md-0-567d7cf787-wkphp   Ready    <none>                 6d23h   v1.21.2+vmware.1-360497810732255795

7、创建工作负载集群

linux-mint-002@linux-mint-002:~/tanzu$  tanzu  cluster create tkg-workload --plan dev
linux-mint-002@linux-mint-002:~/tanzu$  tanzu  cluster list
  NAME          NAMESPACE  STATUS   CONTROLPLANE  WORKERS  KUBERNETES        ROLES   PLAN
  tkg-workload  default    running  1/1           1/1      v1.21.2+vmware.1  <none>  dev

8、获取工作集群的kubeconfig，并查看集群信心

linux-mint-002@linux-mint-002:~/tanzu$ tanzu  cluster  kubeconfig get tkg-workload --admin
linux-mint-002@linux-mint-002:~/tanzu$  kubectl  config get-contexts
CURRENT   NAME                              CLUSTER        AUTHINFO             NAMESPACE
*         tanzu-admin@tanzu                 tanzu          tanzu-admin
          tkg-workload-admin@tkg-workload   tkg-workload   tkg-workload-admin

切换kubecontext
linux-mint-002@linux-mint-002:~/tanzu$  kubectl  config use-context tkg-workload-admin@tkg-workload
Switched to context "tkg-workload-admin@tkg-workload".

linux-mint-002@linux-mint-002:~/tanzu$  kubectl  get no
NAME                                STATUS   ROLES                  AGE    VERSION
tkg-workload-control-plane-nbddz    Ready    control-plane,master   6d2h   v1.21.2+vmware.1-360497810732255795
tkg-workload-md-0-c7bc5dc9f-zwjfg   Ready    <none>                 6d2h   v1.21.2+vmware.1-360497810732255795

linux-mint-002@linux-mint-002:~/tanzu$ kubectl  get po --all-namespaces
NAMESPACE        NAME                                                       READY   STATUS      RESTARTS   AGE
