hello, the error is due to the node not syncing, therefore aeternal cannot find any blocks.

Everything should work correctly if you change the docker compose in a way so it connects to a external node:

version: '3.1'
services:
    image: aeternity/aeternal:latest
    ports:
      - "8080:80"
      - "3020:3020"
    entrypoint: ./docker/wait-for-it.sh node:3013 -- ./aeternal -p -s -w
    environment:
      - NODE_URL=ADDRESS_OF_YOUR_NODE:3013
      - AESOPHIA_URL=compiler:3080
      - DATABASE_URL=postgres://middleware:middleware@db/middleware
      - LOG_CONF=/logs/log.yaml
    volumes:
      - ${PWD}/docker/wait-for-it.sh:/app/docker/wait-for-it.sh
    depends_on:
      - db
      - node
      - compiler

  db:
    image: postgres:11
    restart: unless-stopped
    environment:
      - POSTGRES_USER=middleware
      - POSTGRES_PASSWORD=middleware
      - POSTGRES_DB=middleware
    volumes: 
      - ae-mdw-postgres-volume:/var/lib/postgresql/data
    expose: [5432]

  compiler:
    image: aeternity/aesophia_http:v4.1.0
    hostname: compiler
    expose: [3080]

volumes:
    ae-mdw-postgres-volume:
      external: false

I am trying but I have some other errors. Can you send me example config file.

E.g

version: '3.1' services: middleware: build: context: . dockerfile: ./docker/Dockerfile ports:

• "8080:80"
• "3020:3020" entrypoint: ./docker/wait-for-it.sh node:3013 -- ./aeternal -p -s -w environment:
• NODE_URL=node:3013
• AESOPHIA_URL=compiler:3080
• DATABASE_URL=postgres://middleware:middleware@db/middleware
• LOG_CONF=/logs/log.yaml volumes:
• ${PWD}/docker/wait-for-it.sh:/app/docker/wait-for-it.sh depends_on:
• db
• node

• compiler

  frontend: build: context: ./frontend/ dockerfile: nginx.Dockerfile args:

  • NODE_URL=http://localhost:8080
  • NODE_WS=http://localhost:3020
  • NETWORK_NAME='TEST NET' ports:
• "8081:80" depends_on:

• middleware

  node: image: aeternity/aeternity:${NODE_TAG} hostname: node expose: [3013, 3113, 3014] environment: AETERNITY_CONFIG: /home/aeterinty/aeternity.yaml volumes:

• ${PWD}/docker/aeternity.yaml:/home/aeterinty/aeternity.yaml

• node_db:/home/aeterinty/node/data/mnesia

  db: image: postgres:11 restart: unless-stopped environment:

• POSTGRES_USER=middleware
• POSTGRES_PASSWORD=middleware
• POSTGRES_DB=middleware volumes:

• ae-mdw-postgres-volume:/var/lib/postgresql/data expose: [5432]

  compiler: image: aeternity/aesophia_http:${COMPILER_TAG} hostname: compiler expose: [3080]

volumes: ae-mdw-postgres-volume: external: false node_db:

Problems: 1 Services - depends on node - should be removed (that should be fine) 2 The node section should be removed in general 3 entrypoint should be modified : entrypoint: ./docker/wait-for-it.sh node:3013 -- ./aeternal -p -s -w node:3013 should be removed and maybe this script node:3013? Can you advice me on that

For node Url I have tried:

• sdk-testnet.aepps.com
• sdk-testnet.aepps.com:3013
• http://sdk-testnet.aepps.com
• https://sdk-testnet.aepps.com:3013

Can someone run it locally using public node, confirm that it is working and send me the docker-compose.yml.

This will be the easiest way for me to get it up and running.

And we are using the develop branch or some tag?

I am preparing an example, will be online soon

@tima-t can you check if the examples works for you?
