Build a Custom Docker image to use ChaosIQ

It’s recommended to use the chaosiq/chaostoolkit Docker image from Docker Hub, which is provided by ChaosIQ. However if you want to build a customer Docker image, so you can add your own extensions the following can be used as a starter for your own Dockerfile:

FROM chaostoolkit/chaostoolkit

RUN apk update && \
    apk add --virtual build-deps libffi-dev openssl-dev gcc python3-dev musl-dev && \
    pip install --no-cache-dir chaostoolkit-kubernetes && \
    pip install --no-cache-dir chaosiq-cloud && \
    apk del build-deps && \
    rm -rf /tmp/* /root/.cache

ADD . /home/svc

WORKDIR /home/svc

Add the above to a Dockerfile, it can the be built with:

docker build -t my/chaostoolkit .

With the above Dockerfile we have added the chaostoolkit-kubernetes as an example customization, you can confirm this has been included by running:

docker run my/chaostoolkit info extensions

You should get an output showing you the Docker image includes the chaostoolkit-kubernetes extension.

Once you have built your local Docker image you can use your custom image in place of the ChaosIQ chaosiq/chaostoolkit image. If you are following the section on How to Run with ChaosIQ with Docker just replace chaosiq/chaostoolkit with your custom image name (my/chaostoolkit).
