Implementing contexts for ssh in kubectl way

ssh-context

Bash wrapper around ssh which provides you ability to use contexts (as in kubectl) for SSH.

Better to describe it with example.

1. You are developer involved in multiple projects. Each project has own dev/staging/production servers, git services, ssh keys, etc.
2. You don't want to manually enter ssh key location each time (or mix your ssh config file).
3. You want to share ssh config of one of the projects.
4. It's not usable to do that with standard ssh toolchain

And here is ssh-context.

1. Project = context
2. Context = separate ssh config, keys, git repos, etc.
3. Use full power of isolated ssh config

Installation

Just place ssh-context bash script in any location from your $PATH, chmod +x against it and run ssh-context bootstrap to init file structure

Optional: Set ssh-context as alias for ssh

Bash: Add this alias to .bashrc or .bash_profile (for OSX):

ZSH: Add this alias to .zshrc

Fish: Add this alias to config.fish

alias ssh="ssh-context wrapper"

Set context per git repo

If you have multiple git repos, like project1, project2, projectN, etc. you may want to use them with different contexts. In that case, run ssh-context switch CONTEXT_YOU_WANT_TO_USE_FOR_THAT_GIT_REPO and context name will be saved to git config ssh.context var in your local repo (remote not affected).

Usage

Install ssh-context

ssh-context bootstrap

Create new context

ssh-context init myproject

Switch context

NOTE: if you run switch inside the folder with git repo, context name will be saved to git config ssh.context, so next time when you will ssh from that folder, context from git config ssh.context will be used automaticly, if you don't set context name explicitly.

ssh-context switch context_name

Connect with current context

ssh-context wrapper <ssh args>
# example:
ssh-context wrapper -vv user@server

Connect with another context

ssh-context wrapper <context> <ssh args>
# example:
ssh-context wrapper anotherproject server
