"A caching proxy. Specialized for package files from Linux distributors, primarily for Debian (and Debian based) distributions but not limited to those. See documentation of Apt-Cacher to learn what it's good for."
A docker implementation of apt-cacher-ng.
Ensure that you have already installed docker. Next, select the method you wish to use for running the container.
This assumes that you have already installed docker-compose. Either clone the project or simply copy the docker-compose.yml file to your host system and execute the compose command from the same folder, like so:
docker-compose pull
docker-compose up -d
If you do not have docker-compose installed, you can simply run the container with docker itself, like so:
docker pull yeticraft/docker-apt-cacher-ng
docker volume create aptcacher-cache
docker run -d -v aptcacher-cache:/var/cache/apt-cacher-ng -p 3142:3142 --name=aptcacher -it yeticraft/docker-apt-cacher-ng
If you have a swarm of nodes and wish to deploy to that, use the following command:
docker stack deploy -c docker-compose.yml aptcacher
Now you can test the container by browsing to the host system's IP on port 3142 (http://<host_system_ip>:3142) where you can see statistics and instructions on using the cacher.
Create /etc/apt/apt.conf.d/01proxy with a single line specifying the cacher as the proxy like so:Acquire::http::Proxy "http://<host_ip_address>:3142";
I found that I needed to follow the advice from TSpark on my Odroid, RaspBerry Pi 4 and similar ARM based evices. This requirement may change (and hopefully disapear) - but for now (and until the repos catch up) this did solve the build/run issues related to the following errors:
W: GPG error: http://ports.ubuntu.com/ubuntu-ports focal InRelease: At least one invalid signature was encountered.
E: The repository 'http://ports.ubuntu.com/ubuntu-ports focal InRelease' is not signed.
For me it was a simple thing - on the host ARM device download the package and install it like so:
cd /tmp
wget http://http.us.debian.org/debian/pool/main/libs/libseccomp/libseccomp2_2.5.1-1_armhf.deb
sudo dpkg -i libseccomp2_2.5.1-1_armhf.deb
After that, I was able to build (and run) the image with no issues.
The information page will report the containers address as the suggested proxy target - DO NOT USE THIS. Instead, use the host system's IP.
The defaut acng.conf that is included is modified to allow full proxying to simplify support for SSL/TLS repositories. This may be a security issue if access is allowed to the service from the open internet. Please consider either changing the configuration or denying access via public interface.
A good source (that was not around when I built this originally) is direct from the Docker docs
