Teamwork makes the dream work for this multi-architecture builder
There has never been a better time to start delivering Spring Boot applications to ARM64 architectures. I’ve been working on ARM64 buildpacks for over a year now and I want you to see how far things have come. These last few days have been leveled-up with help from Daniel Mikusa and Salman Malik, and the results are amazing.
So close
I’m excited because the builder for ARM64 is so close to the AMD64 builder supported by Paketo. To see just how close things are, we can do a simple diff of the builders, from different architectures.
Optionally, clear cached images first
docker system prune -a --volumes -f
Inspect with ARM64
On an ARM64 device:
pack builder inspect dashaun/builder:tiny > ~/dashaun.builder.tiny.arm64
The file should look like this:

Now, take a look at the diff between those two files:
diff dashaun.builder.tiny.arm64 dashaun.builder.tiny.amd64
As I’m writing this, the diff looks like this:
< Inspecting builder: 'dashaun/builder:tiny'
---
> Inspecting builder: 'paketobuildpacks/builder:tiny'
11c11
< Trusted: No
---
> Trusted: Yes
When you use dashaun/builder:tiny on ARM64, you are getting dashaun/builder:tiny which is my version. If you use dashaun/builder:tiny on AMD64, you are actually using paketobuildpacks/builder:tiny from Paketo. So this is an easy way, to use my unsupported builder when you are on ARM64, and stay with the supported upstream on AMD64.
Teamwork
I’ve delivered dozens of stacks, buildpacks, and builders. It took a couple of hours of pairing with Salman Malik, to get to the nice diff with upstream. I also spent a few hours on Slack with Daniel Mikusa, cleaning and troubleshooting the manifest creation.
UPX
Another big milestone from this work, is that UPX compression now works on ARM64. Well, it was working for a while, then it was broken, but now it’s working again. When it was working before, the containers were still rather large, so you couldn’t really see the value of the UPX compression. By taking the time to upgrade the underlying stack from Ubuntu Focal to Ubuntu Jammy I was also able to reduce the UPX compressed OCI image size.
Check out the difference this makes for dev.dashaun.service.gateway, the example I worked on last week.
$ docker images | grep gateway
dashaun/dev.dashaun.service.gateway 0.0.4 3f91fcfc6324 42 years ago 194MB
dashaun/dev.dashaun.service.gateway 0.0.5 f5d179a7b5c7 42 years ago 49.7MB
These images are public on my Docker Hub.
Paketo 2023 Roadmap Discussion
I found out yesterday, now I’m sharing with you today, December 12, 2022. The discussion for the Paketo 2023 Roadmap is open. I would really appreciate any support you could put toward prioritizing ARM64 in this open discussion.
