微服務架構電商開發Docker部署從零起步之[004]：配置微服務的docker開發及其部署環境

原創 zhengzizhi 2018-08-26 22:40

Docker編譯啓動入口 spring-cloud-store/run.sh

#!/usr/bin/env bash

set -e

# Build the project and docker images
mvn clean install

# Export the active docker machine IP
export DOCKER_IP=$(docker-machine ip $(docker-machine active))

# docker-machine doesn't exist in Linux, assign default ip if it's not set
DOCKER_IP=${DOCKER_IP:-0.0.0.0}

# Remove existing containers
docker-compose stop
docker-compose rm -f

# Start the config service first and wait for it to become available
docker-compose up -d config-service

while [ -z ${CONFIG_SERVICE_READY} ]; do
  echo "Waiting for config service..."
  if [ "$(curl --silent $DOCKER_IP:8888/actuator/health 2>&1 | grep -q '\"status\":\"UP\"'; echo $?)" = 0 ]; then
      CONFIG_SERVICE_READY=true;
  fi
  sleep 2
done

# Start the discovery service next and wait
docker-compose up -d discovery-service

while [ -z ${DISCOVERY_SERVICE_READY} ]; do
  echo "Waiting for discovery service..."
  if [ "$(curl --silent $DOCKER_IP:8761/actuator/health 2>&1 | grep -q '\"status\":\"UP\"'; echo $?)" = 0 ]; then
      DISCOVERY_SERVICE_READY=true;
  fi
  sleep 2
done

# Start the other containers
docker-compose up -d

# Attach to the log output of the cluster
docker-compose logs

微服務部署在Docker上的啓動順序由 spring-cloud-store/docker-compose.yml 來定義：

config-service:
  image: zigoo/config-service
  environment:
   - SPRING_PROFILES_ACTIVE=docker
   - DOCKER_IP=$DOCKER_IP
  ports:
   - 8888:8888
mysql:
  image: mysql:5.7
  ports:
   - 3306:3306
  environment:
   - MYSQL_ROOT_PASSWORD=dbpass
   - MYSQL_DATABASE=dev
neo4j:
  image: neo4j:2.3
  ports:
   - 7474:7474
  environment:
   - NEO4J_AUTH=none
mongo:
  image: mongo:3.3
  ports:
   - 27017:27017
redis:
  image: redis:3.0
  ports:
   - 6379:6379   
discovery-service:
  image: zigoo/discovery-service
  ports:
   - 8761:8761
  environment:
   - SPRING_PROFILES_ACTIVE=docker
   - DOCKER_IP=$DOCKER_IP

如何刪除已經發布到https://hub.docker.com/倉庫中鏡像

cd /opt/codes/spring-cloud-store && docker-compose stop && docker-compose rm -f     刪除所有容器鏡像
cd /opt/codes/spring-cloud-store && docker-compose up -d    啓動所有容器服務
