Dear FAI Users: Here's the abridged version of my question: How do I add a 3rd party package repository and then install software from it?
Now here's the longer version. I want to install Docker CE (https://www.docker.com/community-edition) on a Debian Stretch system using FAI. The official Docker documentation recommends that you install Docker using their package repository ( https://docs.docker.com/install/linux/docker-ce/debian/#install-using-the-repository). I'm not sure how do this with FAI. The given instructions for installing Docker are as follows. 1. Install packages to allow apt to use a repository over HTTPS: sudo apt-get -y install \ apt-transport-https \ ca-certificates \ curl \ gnupg2 \ software-properties-common 2. Add Docker's official GPG key to APT: curl \ -fsSL \ https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")/gpg \ | sudo apt-key add - 3. Add the Docker repository to APT: sudo add-apt-repository \ "deb [arch=amd64] https://download.docker.com/linux/$(. /etc/os-release; echo "$ID") \ $(lsb_release -cs) \ stable" 4. Update the APT package index: sudo apt-get update 5. Install the docker-ce package: sudo apt-get install docker-ce Here is my solution attempt. I decided to create an FAI class called DOCKER for this installation. First I create the following hook for the DOCKER class (/srv/fai/config/hooks/repository.DOCKER): #!/bin/bash # Install required packages for add-apt-repository utility sudo apt-get install \ apt-transport-https \ ca-certificates \ curl \ gnupg2 \ software-properties-common # Add the Docker repository sudo add-apt-repository \ "deb [arch=amd64] https://download.docker.com/linux/$(. /etc/os-release; echo "$ID") \ $(lsb_release -cs) \ stable" Next I download the Docker repository public key and placed it in the FAI package configuration directory at the following path: /srv/fai/config/package_config/DOCKER.asc Then I create the following package configuration file for the DOCKER class (/srv/fai/config/package_config/DOCKER): # Install Docker CE (Community Edition) PACKAGES install docker-ce Finally I perform a dirinstall/chroot installation using the DOCKER class: sudo fai \ --verbose \ --cfdir '/etc/fai' \ --class 'FAIBASE DEBIAN DOCKER' \ --cspace 'file:///srv/fai/config' \ dirinstall 'docker' Then I enter the chroot environment to check whether or not the installation was successful: sudo chroot docker Unfortunately when I check for docker it does not appear to be installed: root@faiserver:/# which docker root@faiserver:/# dpkg -l | grep -i docker Checking the log files for evidence of the docker-ce package yields the following: root@faiserver:/# grep -Fir docker-ce /var/log/fai/faiserver/last/fai.log WARNING: These unknown packages are removed from the installation list: docker-ce I also look for evidence that the add-apt-repository command was executed, but don't find any: root@faiserver:/# grep -Firl add-apt-repository /var/log/fai root@faiserver:/# However I am able to verify that the key was added to APT successfully: root@faiserver:/# apt-key list 2>/dev/null | grep -i -B2 -A1 docker pub rsa4096 2017-02-22 [SCEA] 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 uid [ unknown] Docker Release (CE deb) <doc...@docker.com> sub rsa4096 2017-02-22 [S] Any suggestions would be greatly appreciated.
