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. |

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

remains false and reaches WithInternal unchanged.

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. |
Seems to work fine, instead of specifying I think this is a much better and more stable approach. |

The proposed solution for the concern about loading the whole registry-dir to memory on volume initialization would require too big refactor imo. I implemented a fix that only loads the cert-dir into memory. That allocation is bounded and small. Fixed the override of node-image issue. |

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.KIND_EXPERIMENTAL_DOCKER_NETWORKfeature, but since this is a potentially unstable feature, i refactored it to instead attach specified containers to the kind cluster network.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
