Building .deb package files for Debian-based OS versions (debian, ubuntu)

Building .deb package files for LROSE using docker

We use Docker containers to build the .deb package files for various Debian-based versions of LINUX.

To make use of these you will need to install docker.

These builds have been tested on the following versions:

• debian 9
• debian 10
• ubuntu 16.04
• ubuntu 18.04
• ubuntu 20.04

Steps in the process

The following are the steps required in the process:

Step	Script to run
Create custom container	make_custom_image.debian
Perform the lrose build	do_lrose_build.debian
Create the package	make_package.debian
Install and test the package	install_pkg_and_test.debian

The details of the steps are as follows:

Create custom container: run make_custom_image.debian.

Create a container, based on the OS image, with the relevant packages installed.

The created container will be called, as an example:

  custom/debian:10

Perform the lrose build: run do_lrose_build.debian.

Perform the build in the custom container.

This creates a new container, that will be called, as an example:

  build.lrose-core/debian:10

Create the rpm: run make_package.debian.

This will create the rpm from the build, and store it in, as an example:

  /tmp/pkg.debian_10.lrose-core/lrose-core-20210217-debian_10.amd64.deb

with a copy in

  $HOME/releases/lrose-core

Install and test the deb: run install_pkg_and_test.debian.

For the test step, the DEB file is installed into a clean container, and one of the applications is run to make sure the installation was successful.

The command we run as a test is:

  RadxPrint -h

On success this will create a log file with the output from RadxPrint.

The log file will be, as an example:

  /tmp/pkg.debian_10.lrose-core/lrose-core.debian_10.install_log.txt

The length of the log file should be over 5000 bytes.

If it is shorter than this, it is likely that an error occurred. Check the log file to see what went wrong.

Location of DEB files

The DEB files are built in the containers, and then copied across onto cross-mounted locations on the host.

After the DEBs are built they are placed in /tmp.

For example:

  /tmp/pkg.debian_9.lrose-core/lrose-core-20210217-debian_9.amd64.deb
  /tmp/pkg.debian_10.lrose-core/lrose-core-20210217-debian_10.amd64.deb
  /tmp/pkg.ubuntu_16.04.lrose-core/lrose-core-20210217-ubuntu_16.04.amd64.deb
  /tmp/pkg.ubuntu_18.04.lrose-core/lrose-core-20210217-ubuntu_18.04.amd64.deb
  /tmp/pkg.ubuntu_20.04.lrose-core/lrose-core-20210217-ubuntu_20.04.amd64.deb

These are also copied into the release directory:

  $HOME/releases/lrose-core

Installing the DEB file on a host system

You use apt-get to install the DEB file on your host.

  apt-get update
  apt-get install -y ./lrose-core-20210217-debian_10.amd64.deb

Note that you need to specify the absolute path, hence the '.'.
