Docker deb builders

Collection of Docker images to build Debian/Ubuntu deb packages. All tested under Ubuntu 18.04LTS (previously 14.04LTS).

• For each package, given Dockerfile will build an OS image and create a target deb package using checkinstall.
• Each extractdeb.sh script will then:
  • Execute the image in a new container.
  • Extract deb package back to the host file system.
  • Destroy the container.

When installing package on target system remember that dependent packages will need to be installed manually, they are not brought over by the checkinstall process.

For Ubuntu: The Docker package from the official Ubuntu repositories is named docker.io due to (somewhat inconveniently) an existing package clash. All build scripts assume you have symlinked the docker.io binary like so:

$ sudo apt install docker.io
$ sudo ln --force --symbolic /usr/bin/docker.io /usr/local/bin/docker

Alternatively (and probably better), install latest stable docker-ce package from Docker's own repository.

Nginx

• OS: Ubuntu 18.04LTS
• Version: 1.14.0
• Configure: nginx/resource/configure.sh

Create and extract package:

$ ./build.sh
# waiting... as Docker builds image

$ ./extractdeb.sh
# package extract from container

$ ls -l nginx_1.14.0-1_amd64.deb
-rw-r--r-- 1 root root 258844 May 8 14:08 nginx_1.14.0-1_amd64.deb

Install on target system:

# should be no dependent packages needed - based off packaged configure.sh
$ sudo dpkg -i /path/to/nginx_1.14.0-1_amd64.deb

PHP-FPM

• OS: Ubuntu 18.04LTS
• Version: 7.2.21 (PHP-FPM and CLI)
• Configure: phpfpm/resource/configure.sh

Create and extract package:

$ ./build.sh
# waiting... as Docker builds image

$ ./extractdeb.sh
# package extract from container

$ ls -l php_7.2.21-1_amd64.deb
-rw-r--r-- 1 root root 9618732 Aug 23 23:18 php_7.2.21-1_amd64.deb

Install on target system:

# install dependent packages - based off packaged configure.sh
$ sudo apt install libcurl3 libjpeg62
$ sudo dpkg -i /path/to/php_7.2.21-1_amd64.deb
