github - Using the ssh agent inside a python script

Question

I'm pulling and pushing to a github repository with a python script. For the github repository, I need to use a ssh key.

If I do this manually before running the script:

eval $(ssh-agent -s)
ssh-add ~/.ssh/myprivkey

everything works fine, the script works. But, after a while, apparently the key expires, and I have to run those 2 cmds again

The thing is, if I do that inside the python script, with os.system(cmd), it doesn't work, it only works if I do that manually

I know this must be a messy way to use the ssh agent, but I honestly don't know how it works, and I just want the script to work, that's all

The script runs once an hour, just in case

Answer 1

While the normal approach would be to run your Python script in a shell where the ssh agent is already running, you can also consider an alternative approach with sshify.py

# This utility will execute the given command (by default, your shell)
# in a subshell, with an ssh-agent process running and your
# private key added to it. When the subshell exits, the ssh-agent
# process is killed.
