NSQのDockerコンテナを立ち上げる

概要

• NSQをDockerで動かしてみる

コンテナ作成

docker-compose.yaml

• https://nsq.io/のドキュメントをそのまま利用してみる

version: '3.7'
services:
  nsqlookupd:
    image: nsqio/nsq
    command: /nsqlookupd
    ports:
      - "4160"
      - "4161"
  nsqd:
    image: nsqio/nsq
    command: /nsqd --lookupd-tcp-address=nsqlookupd:4160
    depends_on:
      - nsqlookupd
    ports:
      - "4150"
      - "4151"
  nsqadmin:
    image: nsqio/nsq
    command: /nsqadmin --lookupd-http-address=nsqlookupd:4161
    depends_on:
      - nsqlookupd
    ports:
      - "4171"

コンテナ起動

docker-compose up -d

• NSQが起動した

docker-compose ps
