ARM64v8 - Raspberry Pi compatible docker image

[arslanakhtar61]

I want to deploy fusionAuth onto ARM64v8 - Raspberry Pi 4. So far the docker images for fusionAuth only support amd64 architecture. Is there a way to deploy fusionAuth docker image on Raspberry Pi 4 k8s cluster?

[mooreds]

I don't see why not, as long as you can run java, and I believe there is support for that architecture. Please feel free to fork and experiment with this.

Jerry Hopper took a look at "aarch64 support, for use on ARM single-board-computers": jerryhopper/fusionauth-install@b10349b

so it looks like you might need to change the java install scripts as well.

Here's more:

DISCLAIMER, this is my first build: i have to double-test everything, but here is where to find the arm64-docker images.
the Java for Arm64 container (JDKv14):
https://hub.docker.com/repository/docker/botnyx/fusionauth-java-aarch64
and the FusionAuth container build with that java :  https://hub.docker.com/repository/docker/botnyx/fusionauth-app-aarch64

@mooreds Thankyou very mush for the effort to build amd64v8 images. I tried to run the images on my raspberry pi 4 but it's throwing an error

$ uname -a 
 Linux ubuntu 5.4.0-1011-raspi #11-Ubuntu SMP Fri May 8 07:43:33 UTC 2020 aarch64 aarch64

#simple enough to just make it run - ignoring sql-database configs
$ docker run \
    -p 9011:9011 \
    --name fusionauth-app \
    botnyx/fusionauth-app-aarch64:latest

standard_init_linux.go:211: exec user process caused "exec format error"

It's throwing the following error in docker logs fusionauth-app
standard_init_linux.go:211: exec user process caused "exec format error"

[mooreds]

Hmmm. I'm not sure what's going on. Unfortunately I can't provide much support for ARM64 images at this time, was just relaying a message from one of our community members who is working on this.

[jerryhopper]

My apologies for this @arslanakhtar61 , but pull the image again, and it works.
there was a problem, since dockerhub doesnt build arm64 (and i lack enough knowledge).

So i now build the image again on my arm64 sbc, and pushed that to dockerhub, and its working now. The downside is that its not automatically updated when FA releases a new version.

I hope to fix automated builds in the future.

[jerryhopper]

Meanwhile, i found a guide to build arm64 containers on dockerhub (https://www.balena.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/).
ill be trying to achieve this, so i can get some automated builds up and running

[arslanakhtar61]

@jerryhopper Thanks alot for the effort.

You could also use the new docker buildx with DOCKER_CLI_EXPERIMENTAL=enabled to build images for multiarch using your x86_x64 architecture machine.
example

 docker buildx build -t botnyx/fusionauth-java-aarch64:latest --platform linux/arm64 .

 docker buildx build -t botnyx/fusionauth-app-aarch64:latest --platform linux/arm64 .

Also I just pulled the latest images and when I try to run using

#simple enough to just make it run - ignoring sql-database configs
$ docker run \
    -p 9011:9011 \
    --name fusionauth-app \
    botnyx/fusionauth-app-aarch64:latest

I get the following error:
tty: ignoring all arguments
/dev/pts/0

Any suggestions on what is going wrong?

[jerryhopper]

Bear with me: its my first aarch64 image, and everything is very expirimental.

The problem: I cant get a Alpine container to work correctly. - So i did some testing with other images.

Ive used a Ubuntu image which seem to work instantly. pull the updated images!

unfortunatly, the image is quite big.

[jerryhopper]

@arslanakhtar61 please try the latest containers: botnyx/fusionauth-app-aarch64:latest

This release uses a adoptopenjdk container, which runs ubuntu. its 267MB big.
I updated the dockerhub-repo, using tags as version.

thanks for your interest in my little fusionauth pet-project.

[arslanakhtar61]

@jerryhopper Great Job!
It's working. Thank you very much.

@mooreds, @jerryhopper can we create like automatic builds using perhaps docker buildx build to publish the latest aarch64 version of docker image (to docker hub botnyx/ maybe) along with the regular amd64 whenever a new version of fusionauth-app is available? Any plan for this?

Will there be an official docker image for aarch64? Especially now when we have arm based AWS instance - EC2.

We can also work on minimizing the size of the docker image in the future. But at least for now, it's working on my raspberry pi 4. Thanks

[jerryhopper]

I will look into that automatic building. for now - i have a nanopi-neo2 dedicated to building arm64 images.
About minimizing the image: i already tried to keep it as small as possible, but if it can be improved - or better - run on alpine - it would be awesome.

Regarding the 'official' image, thats totally up to the FusionAuth staff. Im just a big fan of fusionauth

[robotdan]

Depends on what we mean by "official". :-)

@arslanakhtar61 or @jerryhopper assuming this is just for fun - but if there is a real business case to run FusionAuth in this embedded mode, perhaps we would be interested in publishing the image.

At a minimum, we could think about accept a PR for the Dockerfile under a contrib directory and let people build it themselves.

[jerryhopper]

For what its worth, after some more fiddling, i produced a image of 108mb in size, and setup a dedicated automated builder. I've used debian-buster as base for this container.

This essentially means there will be a automated build every time there is a new official dockerimage was released.

The automated arm64 builds can be found here :

[arslanakhtar61]

Great Job @jerryhopper. Thanks a lot for the effort. I will now start pulling fusionauth images for my raspberry pi 4 arm64 board from your dockerhub repo.

[robotdan]

yes, thanks for your contribution @jerryhopper !
