# bulk-ssh-using-tmux
Just a brief description of how I use tmux to ssh into multiple ec2 instances running on AWS ASG from my Mac
1. Install homebrew from https://brew.sh/
2. `brew install fish`
3. `brew install jq`
4. `brew install tmux`
5. `gem install tmuxinator`. (If you don't like tmuxinator, you may try out [Teamocil](http://www.teamocil.com/) or [tmuxp](https://tmuxp.git-pull.com). However, the below code is based on tmuxinator yaml)
6. Create the below tmuxinator file
```
# ~/.tmuxinator/dynamic-ssh.yml
name: dynamic-ssh
root: ~
windows:
- win1:
layout: tiled
panes:
<% @args.each_with_index do |machine, idx| %>
- pane<%= idx + 1 %>:
- ssh @<%= machine %>
<% end %>
```
If you frequently connect to new hosts and want to avoid specifying yes everytime, you can add `-o StrictHostKeyChecking=no` to your ssh command. More info [here](https://unix.stackexchange.com/questions/33271/how-to-avoid-ssh-asking-permission)
7. Create the below fish function
```
# ~/.config/fish/functions/launch.fish
function launch
tmuxinator start dynamic-ssh ( curl "{API-URL-to-get-JSON-array-of-ec2-instance-name}" | jq -r 'join("\n" )' )
end
```
