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-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
