Add NATS Streaming stack for ARM

[rgee0]

Expected Behaviour

Create ARM equivalents of docker-compose.extended.yml

Current Behaviour

Currently docker-compose.extended.yml is aimed at x86_64.

Possible Solution

Create armhf and arm64 equivalents of docker-compose.extended.yml.
n.b. Full arm64 support is currently WIP so depending upon timings it may make sense to create the armhf equivalent initially.

Once #321 is merged the consolidated deployment script will need amending to enable deployment of extended on arm.

Context

Addressing inconsistencies across hw platforms to simplify deployment and provide a more uniform user experience.

Thanks.

Did you find the multi-arch images from nats.io for testing on ARM/RPi?

I can see "NATS" is multi-arch but not NATS-Streaming which is what we need.

https://hub.docker.com/r/library/nats-streaming/

Marking as blocked and pinging NATS team.

Sample Docker image is available at: docker pull petemiron/nats-streaming-server-arm64

Full multi-platform support will be available once this is merged: nats-io/nats-streaming-docker#8 waiting on nats-streaming-server 0.6.0 release, which should be out end of this week (10/27/2017).

Hey Peter, thank you. This will be very helpful for a Hyper armv demo and for Packet. I need the 32-bit version for Raspberry Pi for the demo we talked about. I'll also have a look at the Dockerfile for this.

@alexellis We have this PR submitted to the official-images repo. We do include an arm32v7 docker image. Hope this is what you were looking for. The PR has not been merged yet, but they usually have a pretty good turn around, so I would not be surprised if this was merged today and available on Docker Hub by EOD.

@alexellis If you need to build your own docker image, it is pretty simple. If you don't need to recompile the server with Go 1.9.2, then simply go on an ARM machine where docker is installed, then either clone repo https://github.com/nats-io/nats-streaming-docker/ and cd into directory arm32v7 or copy the content of this directory locally and then build the image:

docker build -t <image name> .

You should now have an ARM32v7 docker image of NATS Streaming v0.6.0 server.

If you need to recompile, generate the executable with the appropriate Go version this way. Note that this is using cross-compile, so you can build from any platform, say macOS:

env CGO_ENABLED=0 GOOS=linux GOARCH=arm GOARM=7 go build -v -a -tags netgo -installsuffix netgo -ldflags "-s -w -X github.com/nats-io/nats-streaming-server/version.GITCOMMIT=`git rev-parse --short HEAD`" -o nats-streaming-server

Copy the generated executable to the directory I mentioned above and build the docker image as described before.

@alexellis It seems that they have merged the PR and there is a tag for arm32v7. However, it seems that there is a problem and the linux/amd64 seem to be unavailable. Not sure what's going on there.

[alexellis]

@kozlovic I think it's all good now for ARMHF - not sure about ARM64?

[alexellis]

This is now available for armhf in our repo.

[kozlovic]

@alexellis we do have an ARM64 image too.

Perfect.. 👍
