To use this image you have to install Docker first.
You can get the trusted build from the Docker Hub registry:
docker pull thbe/cups
Alternatively, you may build the Docker image from the source code on GitHub.
You can use two environment variables that will be recognized by the start script.
If this environment variable is set, the string will be used as the password for the root user.
If this environment variable is set, the scripts inside the container will run in debug mode.
The instance can be started by the start script from GitHub:
wget https://raw.githubusercontent.com/thbe/docker-cups/master/start_cups.sh
export CUPS_PASSWORD='SeCre!1'
chmod 755 start_cups.sh
./start_cups.sh
You can use the standard Docker commands to examine the status of the CUPS instance:
docker logs --tail 1000 --follow --timestamps cups
The next release of this Docker image should have a persistent CUPS configuration.
The username for the print server is root/password unless you don't change the password with the environment
variable as described in the Environment variables
section.
Simply download the trusted build from the Docker Hub registry:
docker pull thbe/cups
You can build the image also from source. To do this you have to clone the docker-cups repository from GitHub:
git clone https://github.com/thbe/docker-cups.git
cd docker-cups
docker build --rm --no-cache -t thbe/cups .
If you need a shell inside the container you can run the following command:
docker exec -ti cups /bin/sh
- Alpine base image
- CUPS binary from official Alpine package repository
