zsh-ec2ssh

zsh-ec2ssh lists up EC2 instances on your AWS account, and you can choose an instance graphically. Then zsh-ec2ssh issues a ssh command to login that instance.

You often login EC2 instances if you are using AWS. Sometimes, you automate server generation, for example using autoscaling group; therefore, IP Addresses are not fixed. In that case, you need to look up the IP Addresses before ssh login. zsh-ec2ssh can make that work easier.

Demo

I used shortcut key in the first half of this demo. And next, I wrote zsh-ec2ssh command to call the function.

Install

zplug

After you setup zplug, write this line in your ~/.zshrc:

zplug "h3poteto/zsh-ec2ssh"

and, install.

$ zplug install

Manually

Cloning from GitHub, and source in your ~/.zshrc:

$ git clone https://github.com/h3poteto/zsh-ec2ssh.git

Requirements

• peco
• myaws

After you install myaws, please set your AWS credentials in ~/.aws/credentials:

[default]
aws_access_key_id = XXXXXX
aws_secret_access_key = XXXXXX

Usage

Login an instance

Please write shortcut setting in your ~/.zshrc:

AWS_PROFILE_NAME=default
AWS_DEFAULT_REGION=ap-northeast-1
SSH_USER=h3poteto
SSH_PRIVATE_KEY_PATH=$HOME/.ssh/id_rsa
SSH_PORT=22

function zsh-ec2ssh-default() { zsh-ec2ssh $AWS_PROFILE_NAME $AWS_DEFAULT_REGION $SSH_USER $SSH_PRIVATE_KEY_PATH $SSH_PORT }
zle -N zsh-ec2ssh-default
bindkey '^t' zsh-ec2ssh-default # Ctrl + t

Using proxy server

If you prepared proxy server in AWS to login the instance, you can use zsh-ec2ssh-with-proxy. At the first, this function lists up EC2 instances to choose the proxy server. Next, this function lists up instances once again to choose the login target server.

Please write shortcut setting in your ~/.zshrc:

AWS_PROFILE_NAME=production
AWS_DEFAULT_REGION=ap-northeast-1
SSH_USER=h3poteto
SSH_PRIVATE_KEY_PATH=/var/opt/keys/.ssh/private.pem
SSH_PORT=22
AWS_PROXY_PROFILE=proxy
SSH_PROXY_USER=proxy-login-user
SSH_PROXY_PRIVATE_KEY_PATH=$HOME/.ssh/id_rsa
SSH_PROXY_PORT=22

function zsh-ec2ssh-production-proxy() { zsh-ec2ssh-with-proxy $AWS_PROFILE_NAME $AWS_DEFAULT_REGION $SSH_USER $SSH_PRIVATE_KEY_PATH $SSH_PORT $AWS_PROXY_PROFILE $SSH_PROXY_USER $SSH_PROXY_PRIVATE_KEY_PATH $SSH_PROXY_PORT }
zle -N zsh-ec2ssh-production-proxy
bindkey '^p' zsh-ec2ssh-production-proxy # Ctrl + p

Your machine --(ssh using SSH_PROXY_USER, SSH_PROXY_PRIVATE_KEY_PATH and SSH_PROXY_PORT)--> proxy server --(ssh using SSH_USER, SSH_PRIVATE_KEY_PATH and SSH_PORT)--> target server
