Bind-mounting the local registry directory into the registry container relies on the CLI's filesystem being visible to the Docker daemon. That breaks when Crossplane itself runs inside a container, since the mount path only exists in the CLI's own filesystem, not the daemon's. Signed-off-by: Nikita Z <nkzk95@gmail.com>

Before review, I want to refactor this again so that the registry-storage works like before by default, and add a config flag for the docker-volume method. I think that will be cleaner and better. |

Merge Risk: 🔵 Low · up to Selecting a custom Docker network sets a process-wide environment variable that is not restored. Impact is narrow because the CLI typically handles one cluster per process. Restoring the variable after cluster creation is a small fix. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Project files can now configure local cluster networking and registry storage. Existing resources can retain outdated certificates or ignore newly selected settings, causing trust failures and configuration drift.

- Around line 158-162: Add an enum validation marker to StorageConfig.Type
permitting only bindMount and volume. Update resolveRunOptions to preserve the
default for empty values and accept those two values, but return an error for
any other non-empty value instead of falling back to bind mounts.

- Around line 162-170: Update runCmd.resolveRunOptions to apply the project
runtime’s Internal default only when the --internal flag was not supplied. Track
flag presence separately from its boolean value so an explicit --internal=false
remains false and reaches WithInternal unchanged.

- Around line 379-416: Update the registry setup before the CA files are written
to compare the persisted CA with certSecret’s CA; when they differ, recreate and
reinitialize the registry so volume storage and the new cluster’s containerd
trust use the new CA. Preserve the existing behavior when the CA matches, and
ensure ensureLocalRegistry does not compare against a CA already overwritten by
this setup.

Not sure if i have to do add any more feature flags. Seems like the maturity level is on the command level, and project subcommands are already marked as [BETA]. I added a note about docker-network being experimental because it is not documented by kind, the only mention if this feature is in the code and this issue. After re-reading it, maybe i should look into if an approach where we instead of using this experimental feature, connect some specified containers to the kind network. I can test if this would work. |

Description of your changes
This PR adds support for running
crossplane projectin devcontainers and closed company networks with the following changes:Add configuration options for KinD in
crossplane-project.yaml.internalKinD kubeconfig.Example crossplane-project file
Support registry data sideloading when running crossplane project in Docker-in-Docker
When running
crossplane projectin a container, bind-mounting the CLI’s local registry directory into the registry container mounts an empty host path, leaving the registry without its certificates and package data.This happens because the generated files are only in the container where the command was ran, and not on the host.
I added a storage interface where the bind-mount implementation ensures we keep old behavior, and a config-flag to use a volume-implementation. This required some refactoring of the code, for example moving where certs are created so they can be initalized in the docker-volume.
Fixes #313
With these changes, a user in a closed company network and devcontainer can run
crossplane projectwith the following files and command:./crossplane-project.yaml
./kind-config.yaml
./image-configs.yaml
