nvca-values-customization

A guide to changing the configuration values of the NVCF Operator Helm chart, including defaults and values generated from deployment settings.

In plain words
What is it for?
Use it to change self-managed defaults, stack-based install values, deployment-time overrides, or scripts used to build the vendored chart values.
Why use it?
It shows where values come from and helps prevent changes being made in generated or packaged files that will later be overwritten.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nvca-values-customization scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
