Go-micro: Docker deployment of micro services, can not modify the registered address of docker-consul

[xigang]

I used docker to start a micro service, and started the docker-consul container, can not modify the registered address of consul.

Dockerfile

FROM ubuntu:latest

RUN mkdir /sms

WORKDIR /sms

ADD . /sms

CMD ["./sms"]

docker-compose.yml

sms:
    build: .
    environment:
        - MICRO_REGISTRY_ADDRESS=http://consul:8501
    volumes:
        - ./logs/:/sms/logs/
        - ./etc/env_strings.conf:/etc/env_strings.conf
    links:
        - consul
consul:
    image: progrium/consul

How should I solve this problem? thx :)

Have you tried not specifying http:// in the registry address?

[xigang]

Error messages that do not specify http:// are the same.

[asim]

Where you have this - MICRO_REGISTRY_ADDRESS=http://consul:8501 change it to - MICRO_REGISTRY_ADDRESS=consul:8501

[asim]

Wait. Your consul address is not different. How would this even work? It's still set to 8500.

Client Addr: 0.0.0.0 (HTTP: 8500, HTTPS: -1, DNS: 53, RPC: 8400)

[xigang]

okay. I try:)

[xigang]

There is still a problem.

Please specify your entire config. It's difficult to debug without having full context.

Here's a simple configuration that does work.

consul:
  command: -server -bootstrap -rejoin
  image: progrium/consul:latest
api:
  command: api
  build: .
  environment:
    - MICRO_REGISTRY_ADDRESS=consul:8500
  links:
  - consul

Hi @asim
After the start of the service, the consul.wath connection service is rejected.I don't know how to solve it:(

docker-compose.yml

sms:
    build: .
    environment:
        - MICRO_REGISTRY_ADDRESS=consul:8500
    volumes:
        - ./logs/:/sms/logs/
        - ./etc/env_strings.conf:/etc/env_strings.conf
    links:
        - consul
consul:
    command: -server -bootstrap -rejoin
    image: progrium/consul:latest
