Nvca Values Customization

Customizing NVCA Operator Chart Values

Use this skill from deploy/helm/nvca-operator.

Values Flow

src/compute-plane-services/nvca/deployments/nvca-operator/   source chart
  -> scripts/ci_vendor_nvca_operator_chart                   applies self-managed defaults
  -> nvca-operator/values.yaml                               vendored chart values
  -> scripts/render_values_from_stack_env.sh                 stack-aware generated values
  -> make install or make install-from-stack                 optional additional overrides

Permanent Defaults

For defaults that every self-managed deployment should receive, edit scripts/ci_vendor_nvca_operator_chart and re-vendor:

make vendor-chart
git diff nvca-operator/values.yaml

The vendoring script already applies defaults such as:

• ngcConfig.clusterSource = "self-managed"
• ngcConfig.serviceKey = "dummy-api-key"
• image.tag remains empty so templates use the published chart version
• selfManaged.nvcaVersion = "$NVCA_VERSION"
• generateImagePullSecret = false
• selfManaged.sharedStorage.imageTag = "$NVCA_SHARED_STORAGE_IMAGE_TAG"
• nameOverride = "nvca-operator"
• fullnameOverride = "nvca-operator"

Do not edit nvca-operator/values.yaml directly for a permanent default. The next vendor run will overwrite it.

Deploy-time Overrides

Use additional_values for one-off validation or environment-specific values:

make install-from-stack \
  stack_repo=../../../deploy/stacks/self-managed \
  stack_env=local \
  additional_values=override.yml

Use deploy-time overrides for secrets, credentials, cluster-specific IDs, and temporary validation changes.

Adding .env Inputs

For version-like values that the vendoring script needs, add a variable to .env, require it in scripts/ci_vendor_nvca_operator_chart, and re-vendor:

MY_NEW_CONFIG=some-value

update_yaml_key ".myConfig = \"${MY_NEW_CONFIG:?MY_NEW_CONFIG is not set}\"" "${TARGET_DIR}/values.yaml"

Validation

make lint
make template
make validate
tools/ci/validate-helm-chart deploy/helm/nvca-operator/nvca-operator \
  -f tools/ci/helm-validate-values/nvca-operator.yaml

Gotchas

• Install-time values are layered after generated stack-aware values.
• Use yq carefully for nested keys and quoted strings.
• Keep Chart.yaml name/version changes in the vendoring script when they are part of the self-managed packaging contract.
• Never commit real service keys or rendered secret material.
