kubectl 安装和命令自动补全

kubectl 安装

centos

cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
EOF
yum install -y kubectl

ubuntu

sudo apt-get update && sudo apt-get install -y apt-transport-https
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee -a /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
sudo apt-get install -y kubectl

命令补全

在linux上

# yum install -y bash-completion
# source /usr/share/bash-completion/bash_completion
# source <(kubectl completion bash)

测试下，没问题后，我们对 /root/.bashrc 加2行代码 ，方便以后每次登录自动生效：

source /usr/share/bash-completion/bash_completion
source <(kubectl completion bash)

在mac上

$ brew install bash-completion
$ source $(brew --prefix)/etc/bash_completion
$ source <(kubectl completion bash)
