We have been offering docker builds for the following architectures:

* amd64

* arm64

* ppc64le


Since we do not have access to a ppc64-based github or self-hosted runner, we have to rely on QEMU emulation in the github actions. This has failed repeatedly in the past few releases due to segfaults the cause of which we can't find. We have put in considerable effort trying to keep this running nontheless, but it keeps causing disproportionate maintenance effort.

Without a native runner it is therefore not practical to keep supporting this.

We shall remove support for ppc64le until further notice.

### Notes

* github runners do support ppc64 since they are based on dotnet which does not seem to be supported on ppc64le

* so even with our own ppc64 server this issue remains because it can't be used as a runner as it stands


### Begin of the insertionInfo for users

If you want to use OpenProject on ppc64le there is still nothing stopping you from simply building the image yourself on a ppc64 machine. This involves 3 steps.

1. Check out the tag you would like to build, e.g.

1. `git checkout v15.3.2`

2. Build the docker image, e.g.

1. `docker build --build-arg BIM_SUPPORT=false -t mydockeruser/myopenproject:15.3.2-ppc64le -f docker/prod/Dockerfile .`

3. Push the image, e.g.

1. `docker push mydockeruser/myopenproject:15.3.2-ppc64le`
