VMware Tanzu社区版初体验

IT知识vmware初体验

要须心地收汗马，孔孟行世目杲杲。这篇文章主要讲述VMware Tanzu社区版初体验相关的知识，希望能为你提供帮助。
VMware Tanzu社区版
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=02、下载tanzu CLI
ll
linux-mint-002@linux-mint-002:< sub> /tanzu$ wget http://192.168.100.18:1234/tce-linux-amd64-v0.9.1.tar.gz
linux-mint-002@linux-mint-002:< /sub> /tanzu$ tar -zxf tce-linux-amd64-v0.9.1.tar.gz
linux-mint-002@linux-mint-002:< sub> /tanzu$ ls
tce-linux-amd64-v0.9.1tce-linux-amd64-v0.9.1.tar.gz
linux-mint-002@linux-mint-002:< /sub> /tanzu$ cd tce-linux-amd64-v0.9.1/
linux-mint-002@linux-mint-002:~/tanzu/tce-linux-amd64-v0.9.1$ ls
bininstall.shuninstall.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
NAMENAMESPACESTATUSCONTROLPLANEWORKERSKUBERNETESROLES
tanzutkg-systemrunning1/11/1v1.21.2+vmware.1management

capi-systemcluster-apiCoreProvidercluster-apiv0.3.23

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$kubectlget no
NAMESTATUSROLESAGEVERSION
tanzu-control-plane-v9jxwReadycontrol-plane,master6d23hv1.21.2+vmware.1-360497810732255795
tanzu-md-0-567d7cf787-wkphpReady6d23hv1.21.2+vmware.1-360497810732255795

7、创建工作负载集群
linux-mint-002@linux-mint-002:< sub> /tanzu$tanzucluster create tkg-workload --plan dev
linux-mint-002@linux-mint-002:< /sub> /tanzu$tanzucluster list
NAMENAMESPACESTATUSCONTROLPLANEWORKERSKUBERNETESROLESPLAN
tkg-workloaddefaultrunning1/11/1v1.21.2+vmware.1dev

【VMware Tanzu社区版初体验】8、获取工作集群的kubeconfig，并查看集群信心
linux-mint-002@linux-mint-002:< sub> /tanzu$ tanzuclusterkubeconfig get tkg-workload --admin
linux-mint-002@linux-mint-002:< /sub> /tanzu$kubectlconfig get-contexts
CURRENTNAMECLUSTERAUTHINFONAMESPACE
*tanzu-admin@tanzutanzutanzu-admin
tkg-workload-admin@tkg-workloadtkg-workloadtkg-workload-admin


切换kubecontext
linux-mint-002@linux-mint-002:< sub> /tanzu$kubectlconfig use-context tkg-workload-admin@tkg-workload
Switched to context "tkg-workload-admin@tkg-workload".


linux-mint-002@linux-mint-002:< /sub> /tanzu$kubectlget no
