HTTP 500 when running agentgateway in docker container

[vitush93]

Following the basic example, but with docker container, is not working:

• connect requests simply fail with status 500
• tried different MCP servers - same problem (not an npx issue)
• same config works fine using a binary
• logs show nothing helpful, even at debug level request gateway=bind/3000 listener=listener0 route_rule=route0/default route=route0 src.addr=172.27.0.1:52514 http.method=GET http.host=localhost http.path=/sse http.version=HTTP/1.1 http.status=500 protocol=mcp duration=0ms

Example docker-compose (minimal):

services:
    image: ghcr.io/agentgateway/agentgateway:0.10.5
    command: [-f, /config/config.yaml]
    environment:
      RUST_LOG: debug
      RUST_BACKTRACE: "1"
    volumes:
      - ./config.yaml:/config/config.yaml:ro
    ports:
      - 3000:3000

with config:

# tried bunch of stuff - see comments
binds:
  - port: 3000
    listeners:
      - routes:
          - policies:
              cors:
                allowOrigins:
                  - "*"
                allowHeaders:
                  - "*"
                  # - mcp-protocol-version
                  # - content-type
                  # - cache-control
            backends:
              - mcp:
                  targets:
                    - name: time
                      stdio:
                        cmd: python
                        args:
                          [
                            "-m",
                            "mcp_server_time",
                            "--local-timezone=Europe/Prague",
                          ]
                    # - name: sequentialthinking
                    #   stdio:
                    #     cmd: npx
                    #     args:
                    #       [
                    #         "-y",
                    #         "@modelcontextprotocol/server-sequential-thinking",
                    #       ]
                    # - name: everything
                    #   stdio:
                    #     cmd: npx
                    #     args: ["-y", "@modelcontextprotocol/server-everything"]
config:
  adminAddr: 0.0.0.0:15000

Hi @vitush93 is this referring to an example in the documentation?

Apologies, somehow I've posted this issue in the wrong project.

Closing - thank you.
