Makes SSHing to AWS instances less painful
Create a file named config.json in one of the standard configuration directories (eg. /etc/awssh for system stuff, ~/.config/awssh for user stuff), inspiring yourself from config.json.dist . The column names can be any of the toplevel properties of an object in an "instance_set" as decribed in here [1]. The special "tag:" prefix can be used to show one of the tags.
To setup some SSH keys, create a folder names "keys" next to the config.json file, and either copy or symlink there the SSH keys that are used to SSH to your instances. The filename should be [email protected], so for example, if your key is named "my_key" in amazon and the user to SSH as is "ec2-user", you'd name the file ec2-user@my_key.pem.
Just put the script somewhere in your path and run it, optionally passing the AWS region to use as a parameter. You can also pass a command to run on the instance after all the options, like this:
awssh --region eu-west-1 -- tail -f /var/log/messages
Passing -- is mandatory, as it'll tell awssh to stop parsing options at this point of the command line.
- Automatically download and setup private keys from AWS when possible.
