Docker Images
This repository contains Dockerfiles used to build Kathará images. A list of the Docker images we provided can be found at this page in the Docker Hub.
We build the images both with docker build and with docker buildx so, if needed, the images can be build also for other architectures.
Currently our images are based on debian9 and debian10 and are compiled for amd64 and for arm64.
If you need images based on other Linux distributions, feel free to create a PR with other Dockerfiles.
Currently available images are:
- kathara/base: used to build all other images. It contains a variety of network tools and some complex services like bind, apache, etc.
- kathara/quagga: extends the base image adding the Quagga routing daemon.
- kathara/frr: extends the base image adding FRRouting.
- kathara/sdn: extends the base image adding OpenVSwitch and Ryu SDN controller.
- kathara/p4: extends the base image adding Behavioral Model (bmv2) to compile P4 code.
Building from source
To build an image from source, enter the directory according to your preferred base image and run make <image_name> to build for the current architecture.
To build an image with docker buildx for multiple architectures use the command make <image_name>-multi.
Beware: building images for multiple architectures is preconfigured to push the images on DockerHub in the Kathará namespace, so if you don't have privileges to push there, please change the Makefile before running make.
Example: make quagga or make quagga-multi.
Extend Kathará Images
The easiest way to extend a Kathará image is to clone this repository, change the Dockerfile according to your needings and locally build the new image.
If you instead prefer to alter (locally) an existing Kathará image refer to the following steps (remember that, by default, Docker needs root or sudo on Linux).
docker pull kathara/<image_name>docker run -tid --name <image_new_name> kathara/<image_name>docker exec -ti <image_new_name> bash- Do your thing, then exit.
docker commit <image_new_name> kathara/<image_new_name>docker rm -f <image_new_name>
