Summary by CodeRabbit

  • Deployment
    • Deployments now start with the default configuration instead of loading configuration from an existing manifest.
    • A manifest is saved after deployment only when Central is included. It contains the assembled Roxie environment and Roxie and Central configuration.
  • Teardown
    • Teardown uses configuration from the cluster manifest when available; if the manifest is missing or unreadable, teardown continues without it.
    • Teardown discovers matching resources across namespaces. The --single-namespace flag is still accepted but is deprecated and has no effect.

📝 Walkthrough

Deployment now starts from the default configuration and saves a manifest containing Roxie and Central settings only when Central is included. Teardown loads the manifest configuration when available and discovers namespaces containing Central and SecuredCluster resources.

Changes: Deployment configuration and manifest

Layer / File(s) Summary
Manifest configuration and deployment flow
internal/manifest/manifest.go, internal/manifest/manifest_integration_test.go, cmd/deploy.go, cmd/shell.go
The manifest uses RoxieManifestConfig to store Roxie and Central settings. Deployment starts from deployer.DefaultConfig() and saves the manifest only when Central is included. Shell configuration assembly receives configBase.AsConfig().

Teardown

Layer / File(s) Summary
Teardown command configuration
cmd/main.go, cmd/teardown.go
Teardown no longer receives deployment settings from command arguments. It loads configuration from the manifest when available and passes that configuration to the deployer. The --single-namespace flag remains accepted but is deprecated and ignored.
Namespace discovery and resource teardown
internal/deployer/deployer.go
Central teardown discovers the namespace containing its CR. SecuredCluster teardown discovers matching CR namespaces and tears down each concurrently. Resource deletion uses the discovered namespace, and per-namespace errors are logged.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: 🟠 High · up to bffe5

With this change, teardown can fail to find the Central and SecuredCluster deployments and still report success, leaving the deployments installed. Deletion failures and API or permission errors are also hidden. The namespace discovery query and error handling need to be fixed before merge.

Pass a nil base when the manifest did not load.

If the manifest is absent or loading fails, clusterConfig remains zero-valued, but AsConfig() still returns a non-nil base. assembleConfigForCommand then skips defaults. With no user overrides, teardown uses empty Central and SecuredCluster namespaces and can report completion without removing either deployment. Keep the base nil unless the manifest loads successfully. (raw.githubusercontent.com)

Restore defaults for configuration sections omitted from the manifest.

When teardown loads a manifest, AsConfig() returns a non-nil base with an empty SecuredCluster.Namespace. assembleConfigForCommand therefore skips DefaultConfig(). Without a user override, SecuredCluster teardown checks an empty namespace and skips the installed resources. Start from deployer.DefaultConfig(), then apply the stored Roxie and Central settings.

Propagate discovery errors instead of treating them as absent CRs. An authorization or API failure currently makes either teardown return success without deleting resources. Skip only when a successful discovery query finds no CRs. (kubernetes.io)

Return per-namespace teardown errors.

If deletion fails in one namespace, this goroutine only logs the error. After wg.Wait(), teardownSecuredCluster returns nil. The command can then report success despite resources remaining. Collect the worker errors and return a joined error after all namespaces finish.

List CRs before filtering by name.

kubectl get <type> <name> -A rejects a named lookup across all namespaces. The v0.36.2 resource builder returns a resource cannot be retrieved by name across all namespaces. Both teardown paths therefore fail discovery. They then skip resource deletion while reporting success. List the CR type with -A, filter the returned items by metadata.name, and return their namespaces. (raw.githubusercontent.com)

Implement auto-discovery for teardown, not relying on the manifest for
secured clusters.

For central we do use the manifest, to learn about which addons need to
be torn down as well.
