plan4better/charts

Helm charts maintained by plan4better. Each chart lives under charts/<name>/ and is published to GitHub Container Registry as an OCI artifact at oci://ghcr.io/plan4better/charts/<name>.

Available charts

Chart	Description	App source
goat	GOAT (Geo Open Accessibility Tool) — WebGIS platform for spatial analysis, accessibility modeling, and collaborative mapping.	plan4better/goat

Installing a chart

helm install <release-name> oci://ghcr.io/plan4better/charts/<chart-name> \
  --version <chart-version> \
  --namespace <namespace> --create-namespace \
  --values your-values.yaml

For example:

helm install goat oci://ghcr.io/plan4better/charts/goat \
  --version 0.1.0 \
  --namespace goat --create-namespace

Verifying signatures

Charts are signed with Sigstore cosign keyless via GitHub Actions OIDC. Verify with:

cosign verify ghcr.io/plan4better/charts/<chart-name>:<version> \
  --certificate-identity-regexp "https://github.com/plan4better/charts/.github/workflows/release.yml.*" \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com

Releases

Chart releases use the tag convention <chart-name>-<version> (e.g. goat-0.1.0). Each tag triggers the release workflow which packages the chart, pushes it to ghcr.io, cosign-signs the digest, and creates a corresponding GitHub Release.

Contributing

PRs welcome. CI runs helm lint, helm unittest, and kubeconform on every PR that touches charts/** — see ci.yml.

helm plugin install https://github.com/helm-unittest/helm-unittest

# Sync sub-chart deps
helm dependency update charts/<chart-name>/

# Lint + test
helm lint --strict charts/<chart-name>/
helm unittest charts/<chart-name>/

# Render with a CI fixture
helm template my-release charts/<chart-name>/ -f charts/<chart-name>/ci/values-external-deps.yaml
