From postmarketOS

When you don't have the access to Internet, it would be annoying to setup route and packet forwarding/masquerading on a PC. What if you just want to install a package from apk repositories, but it depends on a lot of packages? This guide shows you how to setup a reverse proxy to APK repositories on PC.

Nginx

We use nginx for example.

Installation

Debian/Ubuntu

# apt-get install nginx

Fedora/RHEL/CentOS/Rocky

# dnf install nginx

Alpine/postmarketOS

# apk add nginx

Configuration

Reverse proxy

The configs could be stored in /etc/nginx/conf.d/ or /etc/nginx/http.d/. In this config we use port 8000.

# nano /etc/nginx/http.d/apk_reverse_proxy.conf
server {
	listen 8000;
	listen [::]:8000;

	location /alpine {
		proxy_pass http://dl-cdn.alpinelinux.org/alpine;
	}

	location /postmarketos {
		proxy_pass http://mirror.postmarketos.org/postmarketos;
	}
}

Local repository server

Like the other HTTP servers, Nginx can serve a local path. Note that a standard HTTP port 80 is used in this example.

# nano /etc/nginx/http.d/apk_local_repo.conf
server {
	listen 80;
	listen [::]:80;

	location /local {
        	alias /home/user/.local/var/pmbootstrap/packages;
	        autoindex on;
	}
}

All-in-one

# nano /etc/nginx/http.d/apk_aio.conf
server {
	listen 80;
	listen [::]:80;

	location /alpine {
		proxy_pass http://dl-cdn.alpinelinux.org/alpine;
	}

	location /postmarketos {
		proxy_pass http://mirror.postmarketos.org/postmarketos;
	}

	location /local {
        	alias /home/user/.local/var/pmbootstrap/packages;
	        autoindex on;
	}
}

Restart

Restart to apply the changes.

systemd distros

# systemctl restart nginx

OpenRC distros

# rc-service nginx restart

Add the repository

# nano /etc/apk/repositories
