AWS CLI和EKSCTL的客户端设置

本文主要是介绍AWS CLI和EKSCTL的客户端设置，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

小结

在Linux环境中对AWS CLI和EKSCTL的客户端进行了设置。

过程

安装AWS CLI

使用以下指令安装：

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install

安装EKSCTL

使用以下指令安装：

# for ARM systems, set ARCH to: `arm64`, `armv6` or `armv7`
ARCH=amd64
PLATFORM=$(uname -s)_$ARCHcurl -sLO "https://github.com/eksctl-io/eksctl/releases/latest/download/eksctl_$PLATFORM.tar.gz"# (Optional) Verify checksum
curl -sL "https://github.com/eksctl-io/eksctl/releases/latest/download/eksctl_checksums.txt" | grep $PLATFORM | sha256sum --checktar -xzf eksctl_$PLATFORM.tar.gz -C /tmp && rm eksctl_$PLATFORM.tar.gzsudo mv /tmp/eksctl /usr/local/bin

在两个Kubernetes Cluster之间切换

在本地环境中的一个Kubernetes Cluster，在AWS中也有一个Kubernetes Cluster，两个环境之间进行切换：

查看两个环境：

[root@Master ~]# kubectl config get-contexts
CURRENT   NAME                                                             CLUSTER                                   AUTHINFO                                                         NAMESPACE
*         kubernetes-admin@kubernetes                                      kubernetes                                kubernetes-admin                                                 xxx@yyy@john-1-cluster.ap-southeast-1.eksctl.io   john-1-cluster.ap-southeast-1.eksctl.io   xxx@yyy@john-1-cluster.ap-southeast-1.eksctl.io 

目前是本地环境，切换至AWS:

[root@Master ~]# kubectl config use-context xxx@yyy@john-1-cluster.ap-southeast-1.eksctl.io
Switched to context "xxx@yyy@john-1-cluster.ap-southeast-1.eksctl.io".
[root@Master ~]# 

查看AWS Kubernetes运行状态：

[root@Master ~]# kubectl get nodes
