Multi-architecture support

[cedricve]

Context

We're creating a ARM Dockerfile, so Kerberos.io can also be used on other architectures as well. Afterwards we can use a manifest tool (http://container-solutions.com/multi-arch-docker-images/) to redirect to architecture specific images.

Registry

Currently the only way is to create separate tags to support different architectures (e.g. machinery-x86, machinery-armv7hf, machineryamd64, etc). This is not clean, therefore Docker is creating an OOTB implementation to support this feature. To be continued.

Manifest tool

We're using Docker's Edge feature docker manifest to map the different architectures.

@dragoncube we can proceed in here.

Hi @cedricve , I am trying to build the docker image on a rpi3 device but I'm getting the folowing error: Step 3/12 : RUN cross-build-start ---> Running in eb11c1cebd50 standard_init_linux.go:178: exec user process caused "exec format error" The command 'cross-build-start' returned a non-zero code: 1 I also tried with 'FROM resin/raspberrypi3-debian' but I get the same error.

We're using Docker's Edge feature docker manifest to map the different architectures. Already compiled the different bases.

https://github.com/kerberos-io/docker/tree/master/base-linux-amd64 https://github.com/kerberos-io/docker/tree/master/base-linux-arm

And added to Docker hub.

we're now manifesting the kerberos/kerberos image. https://hub.docker.com/r/kerberos/kerberos
