# Podman MCP Server Test Results
|
|
|
|
**Date**: 2026-01-08
|
|
**Status**: Configuration Complete ✅
|
|
|
|
## Configuration Summary
|
|
|
|
### MCP Configuration File
|
|
**Location**: `c:/Users/games3/AppData/Roaming/Code/User/mcp.json`
|
|
|
|
```json
|
|
"podman": {
|
|
"command": "npx",
|
|
"args": ["-y", "docker-mcp"],
|
|
"env": {
|
|
"DOCKER_HOST": "ssh://root@127.0.0.1:2972/run/podman/podman.sock"
|
|
}
|
|
}
|
|
```
|
|
|
|
### Key Configuration Details
|
|
- **Package**: `docker-mcp` (community MCP server with SSH support)
|
|
- **Connection Method**: SSH to Podman machine
|
|
- **SSH Endpoint**: `root@127.0.0.1:2972`
|
|
- **Socket Path**: `/run/podman/podman.sock` (inside WSL)
|
|
|
|
## Podman System Status
|
|
|
|
### Podman Machine
|
|
```
|
|
NAME VM TYPE CREATED CPUS MEMORY DISK SIZE
|
|
podman-machine-default wsl 4 weeks ago 4 2GiB 100GiB
|
|
```
|
|
|
|
### Connection Information
|
|
```
|
|
Name: podman-machine-default-root
|
|
URI: ssh://root@127.0.0.1:2972/run/podman/podman.sock
|
|
Default: true
|
|
```
|
|
|
|
### Container Status
|
|
Podman is operational with 3 containers:
|
|
- `flyer-dev` (Ubuntu) - Exited
|
|
- `flyer-crawler-redis` (Redis) - Exited
|
|
- `flyer-crawler-postgres` (PostGIS) - Exited
|
|
|
|
## Test Results
|
|
|
|
### Command Line Tests
|
|
✅ **Podman CLI**: Working - `podman ps` returns successfully
|
|
✅ **Container Management**: Working - Can list and manage containers
|
|
✅ **Socket Connection**: Working - SSH connection to Podman machine functional
|
|
|
|
### MCP Server Integration Tests
|
|
✅ **Configuration File**: Updated and valid JSON
|
|
✅ **VSCode Restart**: Completed to load new MCP configuration
|
|
✅ **Package Selection**: Using `docker-mcp` (supports SSH connections)
|
|
✅ **Environment Variables**: DOCKER_HOST set correctly for Podman
|
|
|
|
## How to Verify MCP Server is Working
|
|
|
|
The Podman MCP server should now be available through Claude Code. To verify:
|
|
|
|
1. **In Claude Code conversation**: Ask Claude to list containers or perform container operations
|
|
2. **Check VSCode logs**: Look for MCP server connection logs
|
|
3. **Test with MCP Inspector** (optional):
|
|
```powershell
|
|
$env:DOCKER_HOST="ssh://root@127.0.0.1:2972/run/podman/podman.sock"
|
|
npx -y @modelcontextprotocol/inspector docker-mcp
|
|
```
|
|
|
|
## Expected MCP Tools Available
|
|
|
|
Once the MCP server is fully loaded, the following tools should be available:
|
|
|
|
- **Container Operations**: list, start, stop, restart, remove containers
|
|
- **Container Logs**: view container logs
|
|
- **Container Stats**: monitor container resource usage
|
|
- **Image Management**: list, pull, remove images
|
|
- **Container Execution**: execute commands inside containers
|
|
|
|
## Troubleshooting
|
|
|
|
### If MCP Server Doesn't Connect
|
|
|
|
1. **Verify Podman is running**:
|
|
```bash
|
|
podman ps
|
|
```
|
|
|
|
2. **Check SSH connection**:
|
|
```bash
|
|
podman system connection list
|
|
```
|
|
|
|
3. **Test docker-mcp package manually**:
|
|
```powershell
|
|
$env:DOCKER_HOST="ssh://root@127.0.0.1:2972/run/podman/podman.sock"
|
|
npx -y docker-mcp
|
|
```
|
|
|
|
4. **Check VSCode Extension Host logs**:
|
|
- Open Command Palette (Ctrl+Shift+P)
|
|
- Search for "Developer: Show Logs"
|
|
- Select "Extension Host"
|
|
|
|
### Common Issues
|
|
|
|
- **Port 2972 not accessible**: Restart Podman machine with `podman machine restart`
|
|
- **SSH key issues**: Verify SSH keys are set up correctly for Podman machine
|
|
- **Package not found**: Ensure npm can access registry (check internet connection)
|
|
|
|
## Next Steps
|
|
|
|
1. Test the Podman MCP server by requesting container operations through Claude Code
|
|
2. If the MCP server isn't responding, check the Extension Host logs in VSCode
|
|
3. Consider testing with alternative packages if `docker-mcp` has issues:
|
|
- `docker-mcp-server` (alternative community package)
|
|
- `docker-mcp-secure` (security-focused alternative)
|
|
|
|
## Additional Notes
|
|
|
|
- The `docker-mcp` package is a community-maintained MCP server
|
|
- It supports both local Docker sockets and remote SSH connections
|
|
- The package uses the `dockerode` library under the hood, which works with both Docker and Podman
|
|
- Podman's API is Docker-compatible, so Docker MCP servers work with Podman
