| # 1. choose a user account on the server, here it will be called "github" | |
| # 2. create a ssh key pair and put the public key in github's authorized_keys | |
| # 3. create a script only editable by root with the following, adjust the | |
| # www-data user accordingly | |
| # #!/bin/bash | |
| # cd <path to git directory> | |
| # runuser -u www-data -- git pull | |
| # runuser -u www-data -- git status | |
| # 4. give permission for github to run it as root by putting the following line | |
| # in /etc/sudoers.d/github | |
| # github ALL=(root) NOPASSWD: <path to script> | |
| # 5. configure the secrets on github repo settings for logging into the server | |
| # $SSH_USER = username, "github" in this example | |
| # $SSH_KEY = private key, the matching public key was put in authorized_keys | |
| # $SSH_HKEY = the line from known_hosts for the server to suppress the warning | |
| # $SSH_HOST = server host/ip | |
| # $SSH_PORT = server port | |
| # $SSH_CMD = use "sudo <path to script>" (so github user runs script as root) | |
