Conversation
BREAKING CHANGE: remove local up, open, and stop; use local gitops cluster with --down for lifecycle management.
📝 WalkthroughWalkthroughThe local CLI now uses declared Cluster and Environment YAML definitions for startup, shutdown, reconciliation, and cleanup. Kind cluster creation manages labeled node volumes through a Docker proxy. Crossplane probes and local resource settings were updated. ChangesLocal GitOps lifecycle
Registry probe configuration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔴 Critical · up to The new GitOps lifecycle can fail to create clusters, leave existing clusters with outdated runtime settings, stop the wrong or no cluster after configuration drift, or reconcile an environment against the wrong cluster. These are merge-blocking correctness and availability risks that should be fixed before merging. Sequence Diagram(s)sequenceDiagram

- Around line 99-100: Update the Docker argument handling around the shift and
exec invocation to replace kind’s existing /var volume argument with
"$volume_name:/var" rather than appending a second mount. Ensure exactly one
/var destination is passed to Docker, and add a test asserting that duplicate
/var mounts are not present.
In `@src/commands/local/gitops.rs`:
- Around line 140-149: Update the prepare_cluster flow used by args.down so it
validates the definition and selects the backend without enforcing existing Kind
mount compatibility during teardown. Allow backend.stop() to run for --down even
when mountRoot has drifted, while preserving the existing mount validation for
startup paths.
In `@src/commands/local/mod.rs`:
- Line 233: Update the LocalCommands::Gitops dispatch and
run_environment_command flow to pass local Cluster overrides into the
Environment path, then have run_environment_definition resolve and activate the
Cluster referenced by Environment.spec.clusterRef before application
reconciliation, including its provider pair and kube context. Add an integration
test where generic CLI provider selection conflicts with the referenced Cluster
and verify the declared Cluster is used.
In `@src/commands/local/start.rs`:
- Line 158: Update the normal startup fast path around crossplane_helm_args() so
healthy existing clusters still validate and apply the desired Crossplane and
crossplane-rbac-manager resource constraints before returning. Either include
resource-policy validation in the healthy check or perform an equivalent
one-time migration, while preserving the existing bootstrap:false behavior.

🌐 Web query:
Docker Engine behavior duplicate volume mounts same destination --volume /var named volume source precedence Moby
💡 Result:
In the Moby (Docker Engine) architecture, when multiple volume mounts are configured for the same destination path within a container, the Docker Engine follows a specific precedence order to determine which mount persists [1][2]. Mounts configured later in the process override those configured earlier if they share the same destination [3][2]. The internal registration process in the Docker daemon (specifically registerMountPoints in daemon/volumes.go) applies mounts in the following sequence, with later steps taking precedence over earlier ones [4][2]: 1. Previously configured mount points (e.g., from the container's existing configuration) [2]. 2. Volumes inherited from other containers via --volumes-from [2]. 3. Bind mounts and other explicit volume mounts defined in the current request (e.g., via -v or --mount flags) [2]. If you attempt to define multiple mounts for the exact same destination, the later configuration will typically dereference and replace the previous one [1][3][2]. While this mechanism ensures the final configuration is deterministic, attempting to use the same destination multiple times can lead to unintended shadowing or errors, particularly when combining different types of mounts (such as image-based volumes and local mounts) [5][6]. Regarding nested paths, Docker does not strictly forbid mounting different volumes to nested directories (e.g., /app and /app/config), but these are processed and mounted according to their configuration order [6][7]. If a parent directory is mounted after a child directory has already been established, it may overshadow the child mount, effectively hiding it from the container's perspective [6]. The Moby project has historically addressed these issues by refining the order in which these mounts are applied, often favoring alphabetical or path-depth sorting to ensure consistent behavior [6]. Top results: [1][3][4][2]

Rewrite kind’s /var mount before invoking Docker.
Line 100 adds a second /var mount while kind already passes --volume /var. Docker rejects repeated destinations in HostConfig.Binds, so kind create cluster fails before node creation. Replace kind’s /var argument with "$volume_name:/var" and retain only one /var mount. Add a test that asserts one /var destination.

Allow --down when the existing Kind mount has drifted.
prepare_cluster runs before the args.down branch. For an existing Kind cluster, it rejects a changed mountRoot before backend.stop() runs. A moved checkout or a corrected definition can then leave the declared node running and unable to stop through gitops cluster --down.
Validate the definition and select the backend before teardown. Skip existing-mount compatibility validation only for --down. Keep that validation for startup.

Activate the Cluster declared by an Environment definition.
Line 233 dispatches after Lines 198-223 activate the generic CLI provider selection. run_environment_definition later loads the referenced Cluster but does not activate its declared provider pair or kube context. On a first Environment reconcile, or when CLI defaults differ, Helm and kubectl can target a different cluster than Environment.spec.clusterRef.
Pass the local Cluster overrides into the Environment path. Resolve and activate the discovered Cluster definition before application reconciliation. Add an integration test with a conflicting generic provider selection.

Apply the resource policy during normal startup.
GitOps startup always sets bootstrap: false. The healthy check does not inspect resource constraints, so existing healthy clusters skip crossplane_helm_args() and retain the old Crossplane and crossplane-rbac-manager constraints.
Make the fast path validate the desired resource state, or run a one-time migration before returning.
