SSH_AUTH_SOCK wrapper and error handling for CI usage of Docker

README.md

Description

This script allows error handling during a CI build. It launches an SSH Agent, executes your custom commands and then stops the SSH Agent. In case of an error, the script and the Agent are immediately stopped.

Usage

./run.sh "all my commands"

/!\ Note the quotes around the commands to run /!\

Example:

./run.sh "make install && make build && make release"

run.sh

#!/bin/sh

# A lot of weird error handling glyphs... Don't worry, just read the comments, and you'll be fine. ;)

    # That's the `finally` part of the script. Feel free to edit it.

    # Stop editing this function after this line.

# Real script goes here. All other code is just some error handling to ensure SSH Agent
# is killed correctly at the end of the script.
