# Create a Git forge with repo2html
|
|
|
|
This tutorial teaches you how to use `repo2html` in a `post-receive` hook to
|
|
auto-generate HTML representations of bare Git repositories on a remote web
|
|
server after you `git push` to them.
|
|
|
|
A Git forge is a website that provides HTML representations of Git
|
|
repositories, so visitors don't need to clone repositories to view their
|
|
contents.

## Prepare your server
|
|
|
|
This section uses `example.com` as a placeholder value. Ensure you replace
|
|
`example.com` with your own domain when following the procedures below.
|
|
|
|
This section assumes the following about your server:
|
|
|
|
- You've generated public and private SSH keys on your local machine.
|
|
- You can access your server through SSH and have root access to your server.
|
|
- You manage your firewall with `ufw`.
|
|
- You use `nginx` as your web server.
|
|
- You use letsencrypt to manage TLS certificates.
|
|
- You've added an A record for `git.example.com`.
|
|
|
|
### Set up a git user
|
|
|
|
Ensure you're in the repo2html git repository, and follow the steps below:
|
|
|
|
1. As root, run `adduser git`.
|
|
2. As root, run `mkdir /var/www/git && chown git:git /var/www/git`.
|
|
3. As root, run `ufw allow 9418`.
|
|
4. Run `su git`.
|
|
5. Run `mkdir ~/.ssh && chmod 700 ~/.ssh`.
|
|
6. Run `touch ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys`.
|
|
7. Add your public ssh key from your local machine to `~/.ssh/authorized_keys`.
|
|
8. Run `mkdir ~/projects`.
|
|
9. Run `git init --bare my-repository`.
|
|
|
|
After you've set up a git user, follow all procedures that don't require root
|
|
as the git user.
|
|
|
|
### Set up nginx
|
|
|
|
1. As root, add the following contents to `/etc/nginx/sites-available/git.example.com`:
|
|
|
|
server {
|
|
root /var/www/git;
|
|
index index.html;
|
|
server_name git.example.com;
|
|
}
|
|
|
|
2. As root, run `ln -s /etc/nginx/sites-available/git.example.com /etc/nginx/sites-enabled/`.
|
|
3. As root, run `nginx -t` to test your nginx configuration.
|
|
4. As root, run `certbot`, and follow the prompts.
|
|
5. As root, run `systemctl restart nginx`.
|
|
|
|
### Install repo2html
|
|
|
|
Ensure you're in the repo2html git repository, and follow the steps below:
|
|
|
|
1. As root, run `make dependencies`.
|
|
2. Run `make`.
|
|
3. As root, run `make install`.
|
|
|
|
### Set up a post-receive hook
|
|
|
|
1. Ensure you're in the `repo2html` Git repository.
|
|
2. Run `mkdir ~/bin`.
|
|
3. Run `echo "PATH="~/bin:$PATH" >> ~/.profile`.
|
|
4. Run `cp assets/post-receive ~/bin`.
|
|
5. Run `chmod u+x ~/bin/post-receive`.
|
|
6. Run `ln -sf ~/bin/post-receive ~/projects/my-repository/hooks/post-receive`.
|
|
7. Run `cp assets/templates/default.html ~/bin`.
|
|
8. In the `assets/post-receive` file, change
|
|
`path/to/directory/containing/template` to `~/bin`
|
|
|
|
### Enable cloning over git://
|
|
|
|
1. Ensure you're in the `repo2html` Git repository.
|
|
2. As root, run `cp assets/git-daemon.service /etc/systemd/system`.
|
|
3. As root, run `systemctl enable --now git-daemon.service`.
|
|
|
|
## Test your post-receive hook locally
|
|
|
|
This section uses `example.com` as a placeholder value. Ensure you replace
|
|
`example.com` with your own domain when following the procedures below.
|
|
|
|
On your local machine, follow the steps below:
|
|
|
|
1. Run `git init my-repository`.
|
|
2. Run `cd my-repository`.
|
|
3. Run `echo "hello" > my-file.txt`.
|
|
4. Run `git add my-file.txt`.
|
|
5. Run `git commit -m "my first commit"`.
|
|
6. Run `git remote add origin git@example.com:~/projects/my-repository`.
|
|
7. Run `git push`.
|
|
8. Navigate to `https://git.example.com/my-repository`.
