This commit includes two main changes:
1. **Fix Dockerfile library path for amd64:**
- I updated the `exporter/Dockerfile` to correctly determine the source path for `libiperf.so.0` when building for different architectures.
- Specifically, for `TARGETARCH=amd64`, the path `/usr/lib/x86_64-linux-gnu/libiperf.so.0` is now used.
- For `TARGETARCH=arm64`, the path `/usr/lib/aarch64-linux-gnu/libiperf.so.0` is used.
- I achieved this by copying the library to a canonical temporary location in the builder stage based on `TARGETARCH`, and then copying it from this location into the final image. This resolves an issue where builds for `amd64` would fail to find the library.
2. **Add Helm chart option to disable dependencies:**
- I added a new option `dependencies.install` (default: `true`) to `charts/iperf3-monitor/values.yaml`.
- This allows you to disable the installation of managed dependencies (i.e., Prometheus Operator via `kube-prometheus-stack` or `prometheus-operator` from TrueCharts) even if `serviceMonitor.enabled` is true.
- I updated the `condition` for these dependencies in `charts/iperf3-monitor/Chart.yaml` to `dependencies.install, serviceMonitor.enabled, ...`.
- This is useful for you if you manage your Prometheus Operator installation separately.
This commit introduces support for the arm64 architecture by:
1. **Updating the Dockerfile:**
* The `exporter/Dockerfile` now uses the `TARGETARCH` build argument to dynamically determine the correct path for `libiperf.so.0`. This allows the same Dockerfile to be used for building both `amd64` and `arm64` images.
2. **Modifying GitHub Workflows:**
* The CI workflow (`.github/workflows/ci.yaml`) and the Release workflow (`.github/workflows/release.yml`) have been updated to build and push multi-architecture Docker images (`linux/amd64` and `linux/arm64`).
* This involves adding the `docker/setup-qemu-action` for cross-compilation and specifying the target platforms in the `docker/build-push-action`.
3. **Helm Chart:**
* No changes were required for the Helm chart as the image tag will now point to a multi-arch manifest, and the default iperf3 server image (`networkstatic/iperf3:latest`) is assumed to be multi-arch. Node selectors in the chart are not architecture-specific.
These changes enable the deployment of the iperf3-monitor on Kubernetes clusters with arm64 nodes.
Add core components for continuous cluster network validation:
- Python exporter (`exporter/`) to run iperf3 tests and expose Prometheus metrics.
- Helm chart (`charts/iperf3-monitor/`) for deploying the exporter as a
Deployment and iperf3 server as a DaemonSet.
- CI/CD workflow (`.github/workflows/release.yml`) for building/publishing
images and charts on tag creation.
- Initial documentation, license, and `.gitignore`.
