Connecting to EC2 using keypair (.pem file) via Fabric
Question:
Anyone has any Fabric recipe that shows how to connect to EC2 using the pem file?
I tried writing it with this manner:
Python Fabric run command returns "binascii.Error: Incorrect padding"
But I’m faced with some encoding issue, when I execute the run() function.
Answers:
Without addressing your encoding issue, you might put your EC2 stuff into an ssh config file:
- ~/.ssh/config
or, if global:
- /etc/ssh_config
There you can specify your host, ip address, user, identify file, etc., so it’s a simple matter of:
ssh myhost
Example:
Host myhost
User ubuntu
HostName 174.129.254.215
IdentityFile ~/.ssh/mykey.pem
For more details: man ssh_config
To use the pem file I generally add the pem to the ssh agent, then simply refer to the username and host:
ssh-add ~/.ssh/ec2key.pem
fab -H ubuntu@ec2-host deploy
or specify the env information (without the key) like the example you linked to:
env.user = 'ubuntu'
env.hosts = [
'ec2-host'
]
and run as normal:
fab deploy
Another thing you can do is set the key_filename in the env variable: https://stackoverflow.com/a/5327496/1729558
