为kubectl配置别名和命令行补齐

配置kubectl的别名和命令行补齐。

配置别名

# vim ~/.bashrc

添加 alias k='kubectl'

# source ~/.bashrc

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi

alias kc='kubectl'
alias kd='kubectl describe'
alias kl='kubectl logs --tail=10'
alias kn='kubens'

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions

配置命令行补齐

# yum install -y bash-completion -y

# chmod +x /usr/share/bash-completion/bash_completion

# /usr/share/bash-completion/bash_completion

# source /usr/share/bash-completion/bash_completion

# source <(kubectl completion bash)

 

# kubectl desc<TAB> no<TAB> node<TAB>

问题：在使用命令行补齐时，必须使用kubectl的全称，使用k不行。

优化：

# source <(kubectl completion bash | sed s/kubectl/k/g)

# k desc<TAB> no<TAB> mas<TAB>

 

为了每次登录，都可以自动加载：

# echo "source <(kubectl completion bash)" >> /etc/bashrc
