Docker-compose for local dev environment

Support
1

Hi,
I’m trying to set up a docker-compose.yml with a simple local network node-farmer environment so I can run queries against it using subspace.js. I have this docker-compose file so far:

version: "3.7"
services:
  node:
    image: ghcr.io/subspace/node:gemini-1b-2022-aug-17
    volumes:
      - node-data:/var/subspace:rw
    ports:
      - "0.0.0.0:9955:9955"
    restart: unless-stopped
    command:
      [
        "--dev",
        "--tmp",
        "--force-authoring",
        "--execution",
        "wasm",
        "--pruning",
        "1024",
        "--keep-blocks",
        "1024",
        "--port",
        "9955",
        "--rpc-cors",
        "all",
        "--rpc-methods",
        "safe",
        "--unsafe-ws-external",
        "--validator",
        "--name",
        "local-test-node"
      ]
    healthcheck:
      timeout: 5s
      interval: 30s
      retries: 5
  farmer:
    depends_on:
      node:
        condition: service_healthy
    image: ghcr.io/subspace/farmer:gemini-1b-2022-aug-17
    volumes:
      - farmer-data:/var/subspace:rw
    restart: unless-stopped
    ports:
      - "0.0.0.0:9944:9944"
    command:
      [
        "--base-path",
        "/var/subspace",
        "farm",
        "--node-rpc-url",
        "ws://node:9944",
        "--ws-server-listen-addr",
        "0.0.0.0:9955",
        "--reward-address",
        "5EnzMQs2srMSMFjCVvgdbBJN6hgcL8PQLZVMAzRs7qYbr27e",
        "--plot-size",
        "2G"
      ]
volumes:
  node-data:
  farmer-data:

docker ps command outputs

CONTAINER ID   IMAGE                                           COMMAND                  CREATED              STATUS                    PORTS                    NAMES

But in the initial logs of the node cli terminal I get this:

node_1    | 2022-08-24 17:29:48 [PrimaryChain] Running JSON-RPC HTTP server: addr=127.0.0.1:9933, allowed origins=None    
node_1    | 2022-08-24 17:29:48 [PrimaryChain] Running JSON-RPC WS server: addr=0.0.0.0:9944, allowed origins=None

My problem Is I cannot access the web sockets via ws://localhost:9955 or ws://localhost:9944

any help appreciated…

OK, after a bit of a struggle, I got this to work and accept connections locally. The issue is

"--rpc-cors",
        "all",

does not work, so you need to specify the local addresses instead of using all.

Here is the updated docker-compose:

version: "3.7"
services:
  node:
    image: ghcr.io/subspace/node:gemini-1b-2022-aug-17
    volumes:
      - node-data:/var/subspace:rw
    ports:
      - "9944:9944"
      # - "0.0.0.0:9955:9955"
    restart: unless-stopped
    command:
      [
        "--dev",
        "--tmp",
        "--force-authoring",
        "--execution",
        "wasm",
        "--pruning",
        "1024",
        "--keep-blocks",
        "1024",
        "--port",
        "9955",
        # "--ws-external",
        "--unsafe-rpc-external",
        "--rpc-cors",
        "ws://localhost,http://localhost,ws://node,http://node,ws://farmer,http://farmer,all,127.0.0.1,localhost",
        "--rpc-methods",
        "safe",
        "--unsafe-ws-external",
        "--validator",
        "--name",
        "local-test-node"
      ]
    healthcheck:
      timeout: 5s
      interval: 30s
      retries: 5
  farmer:
    depends_on:
      node:
        condition: service_healthy
    image: ghcr.io/subspace/farmer:gemini-1b-2022-aug-17
    volumes:
      - farmer-data:/var/subspace:rw
    restart: unless-stopped
    ports:
      - "0.0.0.0:9955:9955"
    command:
      [
        "--base-path",
        "/var/subspace",
        "farm",
        "--node-rpc-url",
        "ws://node:9944",
        "--ws-server-listen-addr",
        "0.0.0.0:9955",
        "--reward-address",
        "5EnzMQs2srMSMFjCVvgdbBJN6hgcL8PQLZVMAzRs7qYbr27e",
        "--plot-size",
        "4G"
      ]
volumes:
  node-data:
  farmer-data:

Might be useful to put it in the documentation for development, specially if the dev wants to work only the frontend or API interactions.

Awesome glad you were able to figure this out! I will get some of these details added to the documentation thank you!
