SSH into your EC2 instances based on their configurations.
Another SSH utility for AWS
$ pip install awsh
If you never configured awscli before.
$ aws configure
Alternatively it can be downloaded on pypi.
It gives you a list of hosts you have access to and preconfigure ssh with the proper key and user (assuming they have not been overridden by a configuration management tool). You can filter by instance name and if it matches only one instance it will log to it.
usage: awsh [-h] [--users USERS [USERS ...]] [--region REGION] [-i KEY_PATH] [-c COMMAND] [-r REMOTE_HOST] [-p REMOTE_PORT] [-l LOCAL_PORT] [--keys KEYS] [--timeout TIMEOUT] [--console-output] [--version] [filter] SSH into AWS instances. The default user list assumes that your instances runs on Ubuntu and or Amazon's AMIs. ex: "awsh --users user1 user2 --region us- west-2 --keys '~/.keys' instance-name". Note that "awsh --users user1 user2 instance-name" will not be parsed properly due to the nature of nargs. In that case you may want to do: "awsh instance-name --users user1 user2". positional arguments: filter Optional name filter. If only one instance is found, it will connect to it directly. optional arguments: -h, --help show this help message and exit --users USERS [USERS ...] Specify the users to try. --region REGION Specify the aws region. -i KEY_PATH, --key-path KEY_PATH Specific key path, overrides, --keys -c COMMAND, --command COMMAND Translates to ssh -C -r REMOTE_HOST, --remote-host REMOTE_HOST Open a tunnels. Translates to ssh -L <local-port >:<remote-host>:<remote-port> <selected-aws-host> -p REMOTE_PORT, --remote-port REMOTE_PORT Port to use on the remote host. -l LOCAL_PORT, --local-port LOCAL_PORT Port to use on the local host. Get overwritten by remote port if not defined. --keys KEYS Directory of the private keys. --timeout TIMEOUT SSH connection timeout. --console-output Display the instance console out before logging in. --version Returns awsh's version.
