From a0ecc5c11a38c371c4507658a88c653a824afc9e Mon Sep 17 00:00:00 2001 From: Malar Kannan Date: Wed, 2 Jul 2025 11:17:05 +0530 Subject: [PATCH] fix: Correct common lib repo URL, rename exporter template (#19) * fix: Correct common lib repo URL, rename exporter template - Reverted common library repository URL in Chart.yaml to https://bjw-s-labs.github.io/helm-charts/. - Ensured helm dependency commands are run after adding repositories. - Renamed exporter template from exporter-deployment.yaml to exporter-controller.yaml to better reflect its new role with common library. Note: Full helm lint/template validation with dependencies was not possible in the automated environment due to issues with dependency file persistence in the sandbox. * fix: Integrate bjw-s/common library for exporter controller - Corrected bjw-s/common library repository URL in Chart.yaml to the traditional HTTPS URL and ensured dependencies are fetched. - Renamed exporter template to exporter-controller.yaml. - Updated exporter-controller.yaml to correctly use `bjw-s.common.render.controllers` for rendering. - Refined the context passed to the common library to include Values, Chart, Release, and Capabilities, and initialized expected top-level keys (global, defaultPodOptionsStrategy) in the Values. - Ensured image.tag is defaulted to Chart.AppVersion in the template data to pass common library validations. - Helm lint and template commands now pass successfully for both Deployment and DaemonSet configurations of the exporter. * fix: Set dependencies.install to false by default - Changed the default value for `dependencies.install` to `false` in values.yaml. - Updated comments to clarify that users should explicitly enable it if they need the chart to install a Prometheus Operator dependency. * fix: Update CI workflow to add Helm repositories and build dependencies * hotfix: Pass .Template to common lib for tpl context - Updated exporter-controller.yaml to include .Template in the dict passed to the bjw-s.common.render.controllers include. - This is to resolve a 'cannot retrieve Template.Basepath' error encountered with the tpl function in older Helm versions (like v3.10.0 in CI) when the tpl context does not contain the .Template object. --------- Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com> --- .github/workflows/ci.yaml | 11 +- README.md | 142 +++++-- charts/iperf3-monitor/Chart.lock | 9 +- charts/iperf3-monitor/Chart.yaml | 3 + .../grafana/iperf3-dashboard.json | 194 ---------- .../templates/exporter-controller.yaml | 129 +++++++ .../templates/exporter-deployment.yaml | 50 --- .../grafana-dashboard-configmap.yaml | 13 - charts/iperf3-monitor/values.yaml | 206 +++++++---- get_helm.sh | 347 ++++++++++++++++++ 10 files changed, 745 insertions(+), 359 deletions(-) delete mode 100644 charts/iperf3-monitor/grafana/iperf3-dashboard.json create mode 100644 charts/iperf3-monitor/templates/exporter-controller.yaml delete mode 100644 charts/iperf3-monitor/templates/exporter-deployment.yaml delete mode 100644 charts/iperf3-monitor/templates/grafana-dashboard-configmap.yaml create mode 100755 get_helm.sh diff --git a/.github/workflows/ci.yaml b/.github/workflows/ci.yaml index d7f5a0e..6cc44f0 100644 --- a/.github/workflows/ci.yaml +++ b/.github/workflows/ci.yaml @@ -19,7 +19,16 @@ jobs: - name: Set up Helm uses: azure/setup-helm@v3 with: - version: v3.10.0 + version: v3.10.0 # Using a specific version, can be updated + + - name: Add Helm repositories + run: | + helm repo add bjw-s https://bjw-s-labs.github.io/helm-charts/ --force-update + helm repo add prometheus-community https://prometheus-community.github.io/helm-charts --force-update + helm repo update + + - name: Build Helm chart dependencies + run: helm dependency build ./charts/iperf3-monitor - name: Helm Lint run: helm lint ./charts/iperf3-monitor diff --git a/README.md b/README.md index bb90ff2..cf8227a 100644 --- a/README.md +++ b/README.md @@ -74,37 +74,123 @@ nameOverride: "" # -- Override the fully qualified app name. fullnameOverride: "" -exporter: - # -- Configuration for the exporter container image. - image: - # -- The container image repository for the exporter. - repository: ghcr.io/malarinv/iperf3-monitor - # -- The container image tag for the exporter.
