Downloads supporting latest ARM versions.

Use Case(s)

Homelab Raspberry PI4 Clusters or A Series machines on Amazon.

I got a simple working version compiling myself: GOOS=linux GOARM=7 GOARCH=arm go build

@abrucker235 The builds on releases.hashicorp.com are still using our older way of building ARM binaries (without CGO and without specifying GOARM). We are working towards updating this but are still figuring out all the combinations of ARM ABIs + GOARM versions we need to build with.

Our CI process currently builds 2 32 bit ARM versions. One using the armel ABI + GOARM=5 and one using the armhf ABI + GOARM=6. They should work on ARMv7 processors as well it just will not take advantage of some of the extra hardware assisted floating point instructions but because Consul doesn't do a lot of floating point math the differences in performance should not be very noticeable.

Could you try out these binaries to see if they work for you: https://app.circleci.com/jobs/github/hashicorp/consul/87686/artifacts

Also of note is that for A series instances in EC2 you should probably use the aarch64/arm64 binary. While running a 32 bit build should also work (I tried our armhf + GOARM=6 build on one), I would imagine the 64 bit build should perform better.

Is this still unsolved?

https://github.com/hashicorp/docker-consul currently breaks, when building the container on a RasperryPi because no build for armv7 is available.

This should be resolved in the upcoming 1.11.0 release with the merge of #11417, as well as upcoming patch releases for 1.10.x, 1.9.x, 1.8.x once the corresponding PRs have been merged and we switch over to the new release process.

This new process will build GOARCH=arm GOARM=5 32-bit binaries (intended for broad compatibility) and GOARCH=arm64 (ARMv8) 64-bit binaries, per the matrix at https://github.com/golang/go/wiki/GoArm

@mikemorris is there any more news on this?

Arch and Ubuntu are showing 1.11.1, whereas the Arm repos for rasbian etc. are only showing 1.10.x

Just wanted to make sure I'd not missed an updated release URI or similar?

Hi @proffalken,

Arch and Ubuntu are showing 1.11.1, whereas the Arm repos for rasbian etc. are only showing 1.10.x

These repositories are not managed by HashiCorp. HashiCorp's Linux repository currently only provides packages for x86_64/amd64 systems.

Binaries for 32-bit ARM can be found at https://releases.hashicorp.com/consul/1.11.1/.

Ok thanks @blake

Hi @proffalken,

HashiCorp's Linux repository currently only provides packages for x86_64/amd64 systems.

I realized my previous comment is no longer accurate. Both 32-bit and 64-bit ARM packages have been available in the Linux package repo since about late Nov / early Dec 2021. This support was added with PR #11417.

Use the following command to add the repo to your APT sources for Ubuntu/Debian.

$ sudo apt-add-repository "deb [arch=armhf] https://apt.releases.hashicorp.com $(lsb_release -cs) main"
