a playground for rsyslog docker tasks - nothing production yet

The docker effort currently uses multiple containers.

Alpine Linux

We intend to use alpine linux for the logging appliance container, because it is small, secure and relatively recently.

Right now, alpine misses some components that we need. So we build some packages ourself. This will most probably be an ongoing activity as we intend to always provide current versions of rsyslog inside the logging application and it looks unlikely alpine will always follow exactly.

Package Build Environment

We use

https://github.com/rgerhards/docker-alpine-abuild/tree/master-rger

to build alpine packages.

This is based on https://github.com/andyshinn/docker-alpine-abuild and only adds a few rsyslog-specific tweaks. Most importantly, it has our own unofficial APK repository enabled (we need this if we need to build based on dependencies newer than there are in the official alpine repositories).

Our custom packages are contained inside the

https://github.com/rgerhards/alpine-rsyslog-extras

repository.

Bootstrap

Note: usr below stands for your user prefix.

To start from scratch, do

• create usr/docker-alpine-abuild image You need to hand-edit it so that the initial build does not use your custom repository.

• create autotools-archive package via usr/alpine-linux-extras

  • cd autotools-archive
  • source ../run Note: there asre some errors in regard to git repository mount point. So far, I do not know where the stem from and how to get rid of them. Fortunately, they do not harm the build process. Ignore them (and send us a PR if you know how to solve this cleanly).

• copy package to your intended destination http server

• rebuild usr/docker-alpine-abuild image reset your hand-edited change, make it use the custom repository again This is important as we need to have the dependencies for future builds.

• rebuild the rest of the packages in usr/alpine-linux-extras We don't want to give the exact sequence here as it might change. In general, rsyslog should be built last. You may need to do multiple uploads to your repo when these dependencies are needed by packages.

• Remember to periodically apply (security) updates to the docker images!
