Bug: Dev Container fails on macOS ARM64 due to architecture and network issues

[charliecheng630]

Environment:

• Dev Container: golang:1.24-bookworm
• Host: macOS on Apple Silicon (ARM64 / aarch64)
• Tools: VS Code + Remote - Containers + Docker Desktop

Problem / Observed Errors:

• kubectl version --client fails with Bus error
• curl downloads fail with PROTOCOL_ERROR
• Docker network creation fails if network kind already exists
• --network=host does not work on macOS Docker Desktop → Go module downloads fail

Impact:

• Apple Silicon (ARM64) users cannot successfully build the Dev Container.
• Current Dev Container scripts assume x86_64 Linux binaries and host network support → incompatible with macOS ARM64.

[charliecheng630]

Root Cause:

• Binary architecture mismatch: Dev Container downloads amd64 binaries (kubectl, kind, kubebuilder), but container runs arm64 → Bus error.
• Host network unsupported on macOS Docker Desktop: causes curl / Go module downloads to fail.
• Docker network creation not idempotent: fails if kind network already exists.
• Missing required packages in minimal container: no curl or ca-certificates → HTTPS downloads fail.

I would like to work on this issue and provide a macOS / ARM64 compatible version of post-install.sh and updated devcontainer.json that:

• Detects architecture automatically
• Downloads correct binaries for kubectl, kind, and kubebuilder
• Uses bridge network on macOS
• Is safe to run on Linux x86_64 as well

I can submit a PR for review if maintainers are open to it.

Go ahead, I can assist with the review.
