We have created a multiarch docker image of our "one fits all" #synapse (#matrix) image. The docker tag is "ppc" and we support ppc64le (powerpc), amd64 and arm64(v8). Feedback if the arm version is working, would be great. 🙂 At the moment it's just a test. If the feedback would be fine, we will merge it.
