Building Traffic Control¶
The build steps for Traffic Control components are all pretty much the same, despite that they are written in a variety of different languages and frameworks. This is accomplished by using Docker.
Currently, both listed methods of building Traffic Control components will produce
*.rpm files, meaning that the support of these components is limited to RedHat-based distributions - and none of them are currently tested (or guaranteed to work) outside of CentOS7, specifically.
This is the easiest way to build all the components of Traffic Control; all requirements are automatically loaded into the image used to build each component.
docker-compose(https://docs.docker.com/compose/install/) (optional, but recommended)
docker-compose is not available, the
pkg script will automatically download and run it in a container. This is noticeably slower than running it natively.
./pkg [options] [projects]
|-q||Quiet mode. Suppresses output.|
|-v||Verbose mode. Lists all build output.|
|-l||List available projects.|
projects argument is given, it should be one or more project names. If it is not given, all projects will be built. Valid projects:
*.rpm files, build logs and source tarballs will be output to the
dist directory at the root of the Traffic Control repository directory.
pkg script fails,
docker-compose can still be used to build the projects directly. The compose file can be found at
infrastructure/docker/build/docker-compose.yml under the repository’s root directory. It is recommended that between builds
docker-compose down -v is run to prevent caching of old build steps. The service names are the same as the project names described above in Usage, and similar to the
pkg script, the build results, logs and source tarballs may all be found in the
dist directory after completion.
Building Individual Components¶
Each Traffic Control component can be individually built, and the instructions for doing so may be found in their respective component’s development documentation.
Building This Documentation¶
This documentation uses the Sphinx documentation build system, and as such requires a Python3 version that is at least 3.4.1, but no greater than 3.6.5. It also has dependency on Sphinx, and Sphinx extensions and themes. All of these can be easily installed using pip by referencing the requirements file like so:
python3 -m pip install --user -r docs/source/requirements.txt
Once all dependencies have been satisfied, build using the Makefile at
Alternatively, it is also possible to Build using pkg.
