Sets up a simple HTTP server. The only endpoint it serves is POST /hook. When
a GitHub webhook is sent there, the request is validated, and the command
specified in the configuration file is run.
$ cargo build --release
$ target/release/gh-hook-command
The path to the configuration file is set by the GH_HOOK_CONFIG environment
variable. If it's unset, ./config.toml is used instead. The file will be
created if it doesn't exist.
# The webhook secret key.
secret = "secret secret really secret"
# Address to bind to.
bind = "0.0.0.0:8000"
# The command list.
[commands]
# This runs `cat /dev/stdin && echo ""' on the `push` event.
push = 'cat /dev/stdin && echo ""'
