+# Improving gVisor Sandboxing Implementation
+
+This document describes improvements to the gVisor sandboxing implementation for the `source-declarative-manifest` connector, specifically addressing permission issues encountered in the original implementation.
+
+## Overview
+
+The original gVisor implementation in [PR #399](https://github.com/airbytehq/airbyte-python-cdk/pull/399) encountered permission issues when attempting to create directories at runtime. This improvement moves critical privileged operations to build time and uses a static configuration file rather than generating it dynamically at runtime.
+
+## Implementation Details
+
+The key changes in this implementation:
+
+1. **Move Directory Creation to Build Time**: 
+   - Create the OCI bundle directory (`/var/run/oci-bundle`) during Docker image build
+   - Set appropriate permissions on the directory to ensure it's accessible by the non-root user
+
+2. **Use Static Configuration File**:
+   - Replace the dynamic config.json generation with a static file
+   - Pre-configure the file for the `spec` command
+   - Copy the config file to the OCI bundle directory during build
+
+3. **Simplify Wrapper Script**:
+   - Remove temporary directory creation and cleanup
+   - Use the pre-created OCI bundle directory
+   - Maintain the fallback mechanism to direct execution if runsc fails
+
+## Technical Approach
+
+### Original Implementation Issues
+
+The original implementation encountered the following error:
+```
+running container: creating container: creating container root directory "/var/run/runsc": mkdir /var/run/runsc: permission denied
+```
+
+This occurred because:
+1. The wrapper script attempted to create directories at runtime
+2. The container was running as a non-root user without the necessary permissions
+3. The `runsc` command requires specific directories to exist with proper permissions
+
+### Solution
+
+The solution addresses these issues by:
+
+1. Creating all required directories during the Docker build process (as root):
+   - `/var/run/oci-bundle/rootfs` - The OCI bundle directory for container execution
+   - `/var/run/runsc` - Primary runsc runtime directory
+   - `/run/runsc` - Alternative runsc runtime directory
+   - `/tmp/runsc` - Temporary runsc directory for runtime operations
+   
+2. Setting appropriate permissions on these directories:
+   - `755` permissions for the OCI bundle directory
+   - `777` permissions for all runsc directories to ensure non-root access
+   
+3. Pre-creating a static config.json file with the `spec` command hardcoded
+4. Copying this file to the OCI bundle directory during build
+5. Executing runsc once during build time as root to create any additional required directories
+6. Simplifying the wrapper script to use the pre-created directories and files
+
+## Testing Results
+
+The implementation was tested by building and running the Docker image with various configurations:
+
+### Basic Run
+```bash
+cd docker/sandbox-poc
+docker build -f Dockerfile.gvisor -t airbyte/source-declarative-manifest-gvisor .
+docker run --rm airbyte/source-declarative-manifest-gvisor spec
+```
+
+The error changed from the original permission denied error to:
+```
+running container: creating container: cannot create gofer process: unable to run a rootless container without userns
+```
+
+The container successfully falls back to direct execution and completes the spec command.
+
+### Privileged Mode
+```bash
+docker run --rm --privileged airbyte/source-declarative-manifest-gvisor spec
+```
+
+Even with privileged mode, the same error occurs:
+```
+running container: creating container: cannot create gofer process: unable to run a rootless container without userns
+```
+
+### User Namespace Support
+```bash
+docker run --rm --userns=host airbyte/source-declarative-manifest-gvisor spec
+```
+
+The user namespace flag also results in the same error:
+```
+running container: creating container: cannot create gofer process: unable to run a rootless container without userns
+```
+
+These tests indicate that while we've resolved the directory permission issues, running gVisor within a container requires additional Docker runtime configuration beyond what can be achieved from within the container itself.
+
+## Considerations for Future Work
+
+1. **Dynamic Command Support**: The current implementation hardcodes the `spec` command in the config.json file. Future work could explore methods to support dynamic commands without requiring privileged operations at runtime.
+
+2. **Production Deployment**: For production use, consider:
+   - Using Docker's runtime configuration to specify runsc as the runtime
+   - Running containers with the necessary privileges for runsc
+   - Implementing a more complete OCI bundle configuration
+
+## FAQ
+
+**Q: Why hardcode the `spec` command instead of making it dynamic?**  
+A: Making the command dynamic would require modifying the config.json file at runtime, which would still be a privileged operation. The current approach focuses on fixing the permission issues first, with dynamic command support as a potential future enhancement.
+
+**Q: Does this implementation still provide the security benefits of gVisor?**  
+A: Yes, when the container has the proper permissions to run runsc, it will use gVisor's sandboxing capabilities. The fallback mechanism ensures the connector still functions in environments without these permissions.
+
+## Closing & Next Steps
+
+This implementation successfully addresses the permission issues in the original gVisor implementation by moving privileged operations to build time. Future work could focus on:
+
+1. Supporting dynamic commands without requiring runtime file modifications
+2. Enhancing the OCI bundle configuration for more comprehensive sandboxing
+3. Testing in environments with proper permissions for runsc
+4. Exploring alternative approaches to pass command-line arguments to the sandboxed application
