- **Health checks**: Ensures DinD is fully ready before proceeding
- **Simple setup**: Direct Docker commands for maximum flexibility
**Why CI_DEPLOY_USER**: The CI_DEPLOY_USER handles deployment orchestration and has sudo access for Docker operations, following the principle of least privilege.
**Why CI_SERVICE_USER**: The CI_SERVICE_USER is in the docker group and runs the CI pipeline, so it needs direct access to the DinD container for seamless CI/CD operations.

**What this does**:
- **Configures insecure registry**: Allows DinD to push to Harbor without SSL verification
- **Configures certificate trust**: Properly sets up Harbor certificate trust in DinD
- **Fixes ownership issues**: Ensures certificate has correct ownership for CA trust
- **Tests connectivity**: Verifies DinD can pull, tag, and push images to Harbor
- **Validates setup**: Ensures the complete CI/CD pipeline will work
