AWS EC2 SSH Autocompletion
A couple scripts to auto-populate your .ssh/config file with a list of hosts from your AWS_EC2 Name tags.
What these scripts will do, so please becareful.
- Overwrite your home/.ssh/config file
- Add autocompletion on MAC OSX in terminal: ssh someserver
- Magic
Note: I have a standard user I use on my instances whether it be my ldap user or the default ec2-user, this is set statically for all instances. You will have to modify the updateSSH.sh file if you use another user. (ie: ubuntu, root, whatever)
Installation
You need will need to have brew installed:
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Install dependencies:
$ brew install bash-completion jq awscli
$ sudo easy_install pip
$ pip install boto
Clone the repo:
$ git clone https://github.com/chad-upton/AWS.EC2.SSH.Autocomplete.git
$ cd AWS.EC2.SSH.Autocomplete
Add your ec2 keypairs to your keychain
- Browse to your ec2_keypair.pem file that you created your instance with and right click -> open with keychain app
Add your EC2 Access Key & Secret Keys
Note: One thing you can do and most have done, is add these to your ~/.bashrc with lines 12-15 so not to have them stored in multiple places. If you do that you will just need to source ~/.bashrc instead.
$ vim updateSSH.sh
Line6: Uncomment and edit: export AWS_ACCESS_KEY_ID='AK123'
Line7: Uncomment and edit: export AWS_SECRET_ACCESS_KEY='abc123'
$ :wq to save
Add Autocomplete to your home/.bashrc
vim ~/.bashrc
# Autocompletion
if [ -f $(brew --prefix)/etc/bash_completion ]; then
. $(brew --prefix)/etc/bash_completion
fi
Copy ec2inventory to /usr/local/bin (optional but make note of paths in updateSSH.sh)
$ cp ec2inventory /usr/local/bin
Copy ec2.ini to /usr/local/bin (optional but again make note of paths)
$ cp ec2.ini /usr/local/bin
Run ec2inventory to make sure it's working
$ source updateSSH.sh (or ~/.bashrc)
$ ec2inventory
You should get a giant output of metadata about your ec2 environment. If no errors then run:
$ updateSSH.sh
If you do get errors, double check your paths are correct and you've added the access/secret keys.
Check your ~/.ssh/config file for new entries
$ cat ~/.ssh/config
Should now see a list of hosts setup like this:
Host some_name_tag
HostName some_private_ip
User some_user
Test Autocompletion
$ ssh some_name_
Notes
- The EC2inventory python script is borrowed from the ansible repository, if you want the latest you are welcome to download it from here: https://raw.githubusercontent.com/ansible/ansible/devel/plugins/inventory/ec2.py
- If you want public IP address instead of private IPs you can change it in the ec2.ini file
Line 38 to: ip_address
