provide linux arm64 binaries

[jameslamb]

Description

For Linux, this project is currently only publishing amd64 binaries on releases.

We should consider also publishing arm64 binaries.

Benefits of this work

• allows install-from-releases workflow to work in arm64 Linux environment

That would be useful because it allows use of this project without needing to set up Go and do go install.

Acceptance Criteria

• releases contain a canary_linux_arm64 binary

Approach

As described in https://www.digitalocean.com/community/tutorials/building-go-applications-for-different-operating-systems-and-architectures#using-your-local-goos-and-goarch-environment-variables, Go has builtin support for cross-compiling, so I think this should be achievable on the GitHub-hosted ubuntu-latest runner, without requiring an arm64 runner.

Like this:

GOOS=linux GOARCH=arm64 go build

Notes

Writing this up specifically from the perspective of RAPIDS. This would be helpful (but not critical) for rapidsai/docker#667, as RAPIDS builds both amd64 and arm64 images there and it's helpful to run those images on amd64 and arm64 runners directly (instead of using emulation).

I think we should just be able to add this to the existing setup in the Makefile.

container-canary/Makefile

Lines 20 to 27 in b67f65e

	package: ## Build for all platforms
	env GOOS=windows GOARCH=amd64 go build -o bin/$(EXECUTABLE)_windows_amd64.exe $(GO_FLAGS) .
	env GOOS=linux GOARCH=amd64 go build -o bin/$(EXECUTABLE)_linux_amd64 $(GO_FLAGS) .
	env GOOS=darwin GOARCH=amd64 go build -o bin/$(EXECUTABLE)_darwin_amd64 $(GO_FLAGS) .
	env GOOS=darwin GOARCH=arm64 go build -o bin/$(EXECUTABLE)_darwin_arm64 $(GO_FLAGS) .
	@echo built: bin/$(EXECUTABLE)_windows_amd64.exe, bin/$(EXECUTABLE)_linux_amd64, bin/$(EXECUTABLE)_darwin_amd64, bin/$(EXECUTABLE)_darwin_arm64

I just tagged v0.3.1 so you should have Linux arm64 builds now.

excellent, thanks!
