一背景介绍

先来看一下我们熟悉的第一代 spring cloud 的组件

spring cloud 现在已经是一种标准了，各公司可以基于它的编程模型编写自己的组件，比如Netflix、阿里巴巴都有自己的一套通过spring cloud 编程模型开发的分布式服务组件。

Spring Cloud 二代组件

Spring Cloud Alibaba 主要包含 Sentinel、Nacos、RocketMQ、Dubbo、Seata 等组件。

二代引入了 Spring Cloud Alibaba

再加上我们常用的组件

这其有中除 spring cloud gateway都需要外部单独部署服务来支持

二利用docker-compose 进行本地简化部署

apollo

version: '2'services:  apollo-quick-start:    image: nobodyiam/apollo-quick-start    container_name: apollo-quick-start    depends_on:      - apollo-db    ports:      - "8080:8080"      - "8070:8070"    links:      - apollo-db  apollo-db:    image: mysql:5.7    container_name: apollo-db    environment:      TZ: Asia/Shanghai      MYSQL_ALLOW_EMPTY_PASSWORD: 'yes'    depends_on:      - apollo-dbdata    ports:      - "13306:3306"    volumes:      - ./sql:/docker-entrypoint-initdb.d    volumes_from:      - apollo-dbdata  apollo-dbdata:    image: alpine:latest    container_name: apollo-dbdata    volumes:      - /var/lib/mysql

注意： ./sql下面的文件在这里(https://github.com/ctripcorp/apollo/tree/master/scripts/sql)，是两个初始化的sql文件

nacos

version: "2"services:  nacos:    image: nacos/nacos-server:latest    container_name: nacos-standalone-mysql    env_file:      - ./env/nacos-standlone-mysql.env    volumes:      - ./standalone-logs/:/home/nacos/logs      - ./init.d/custom.properties:/home/nacos/init.d/custom.properties    ports:      - "8848:8848"      - "9555:9555"    depends_on:      - mysql    restart: on-failure  mysql:    container_name: mysql    image: nacos/nacos-mysql:5.7    env_file:      - ./env/mysql.env    volumes:      - ./mysql:/var/lib/mysql    ports:      - "3308:3306"

redis

version: '2'services:  #redis容器  redis:    #定义主机名    container_name: redis    #使用的镜像    image: redis:6.0.8    #容器的映射端口    ports:      - 6379:6379    command: redis-server /etc/conf/redis.conf    #定义挂载点    volumes:      - ./data:/data      - ./conf:/etc/conf    #环境变量    privileged: true    environment:      - TZ=Asia/Shanghai      - LANG=en_US.UTF-8

注意： conf下的redis.conf配置文件可以找个默认的模版文件，然后进行相应修改

rocket-mq

version: '2'services:  #Service for nameserver  namesrv:    image: apacherocketmq/rocketmq-nameserver:4.5.0-alpine-operator-0.3.0    container_name: rmqnamesrv    ports:            - 9876:9876    volumes:           - ./data/namesrv/logs:/home/rocketmq/logs    command: sh mqnamesrv    environment:      TZ: Asia/Shanghai      JAVA_OPT_EXT: "-server -Xms512m -Xmx512m -Xmn256m"  #Service for broker  broker:    image: apacherocketmq/rocketmq-broker:4.5.0-alpine-operator-0.3.0    container_name: rmqbroker-a    depends_on:           - namesrv    ports:            - 10909:10909      - 10911:10911      - 10912:10912    environment:            NAMESRV_ADDR: namesrv:9876      JAVA_OPT_EXT: "-server -Xms512m -Xmx512m -Xmn256m"    volumes:            - ./data/broker/logs:/home/rocketmq/logs           - ./data/broker/store:/home/rocketmq/store            - ./data/broker/conf/broker.conf:/opt/rocketmq-4.7.1/conf/broker.conf    command: sh mqbroker -c /opt/rocketmq-4.7.1/conf/broker.conf #Service for another broker -- broker1  broker1:    image: apacherocketmq/rocketmq-broker:4.5.0-alpine-operator-0.3.0    container_name: rmqbroker-b    depends_on:           - namesrv    ports:            - 10929:10909      - 10931:10911      - 10932:10912    environment:            NAMESRV_ADDR: namesrv:9876      JAVA_OPT_EXT: "-server -Xms512m -Xmx512m -Xmn256m"    volumes:            - ./data1/broker/logs:/home/rocketmq/logs            - ./data1/broker/store:/home/rocketmq/store            - ./data1/broker/conf/broker.conf:/opt/rocketmq-4.7.1/conf/broker.conf    command: sh mqbroker -c /opt/rocketmq-4.7.1/conf/broker.conf  rmqconsole:    image: styletang/rocketmq-console-ng    container_name: rmqconsole    ports:      - 8180:8080    environment:        TZ: Asia/Shanghai        JAVA_OPTS: "-Drocketmq.namesrv.addr=namesrv:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false"    depends_on:      - namesrv

此外还有两个配置文件

./data/broker/conf/broker.conf
./data1/broker/conf/broker.conf

## ./data/broker/conf/broker.confbrokerClusterName = DefaultClusterbrokerName = broker-abrokerId = 0deleteWhen = 04fileReservedTime = 48brokerRole = ASYNC_MASTERflushDiskType = ASYNC_FLUSH### ./data1/broker/conf/broker.confbrokerClusterName = DefaultClusterbrokerName = broker-bbrokerId = 0deleteWhen = 04fileReservedTime = 48brokerRole = ASYNC_MASTERflushDiskType = ASYNC_FLUSH

seata-server

version: "3.1"services:  seata-server:    image: seataio/seata-server:latest    hostname: seata-server    ports:      - 8091:8091    environment:      - SEATA_PORT=8091    expose:      - 8091

sentinel

没有现成的docker镜像，需要自己编写一个

FROM openjdk:8#复制上下文目录下的jar包到容器里  使用COPY命令亦可ADD sentinel-dashboard-1.8.0.jar sentinel-dashboard-1.8.0.jarEXPOSE 8080#指定容器启动程序及参数    ""ENTRYPOINT ["java","-jar","sentinel-dashboard-1.8.0.jar"]

利用自己编译的镜像再编写docker-compose配置文件

version: '3'services:  sentinel-dashboard:    image: sentinel-dashboard:1.8.0    container_name: sentinel-dashboard    restart: always    environment:      JAVA_OPTS: "-Dserver.port=8080 -Dcsp.sentinel.dashboard.server=localhost:8080 -Dproject.name=sentinel-dashboard -Djava.security.egd=file:/dev/./urandom -Dcsp.sentinel.api.port=8719"    ports: #避免出现端口映射错误，建议采用字符串格式 8080端口为Dockerfile中EXPOSE端口      - "58080:8080"      - "8719:8719"    volumes:      - ./root/logs:/root/logs

xxl-job

version: '3'services:  xxl-job-admin:    image: xuxueli/xxl-job-admin:2.2.0    restart: always    container_name: xxl-job-admin    depends_on:      - mysql    environment:      PARAMS: '--spring.datasource.url=jdbc:mysql://mysql:3306/xxl_job?Unicode=true&characterEncoding=UTF-8 --spring.datasource.username=root --spring.datasource.password=root'    ports:      - 8067:8080    volumes:      - ./data/applogs:/data/applogs

注意：这时引用的数据库是你现有的mysql，找一个现有的，因为为了它再新建一个容器有点儿浪费

prometheus(altermanager+prometheus+grafana)

version: '3'services:  prometheus:    image: prom/prometheus:latest    container_name: prometheus    volumes:      - /opt/docker_compose/monitor/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml      - /opt/docker_compose/monitor/prometheus/alertmanager_rules.yml:/etc/prometheus/alertmanager_rules.yml    ports:      - 9090:9090    command:      - '--config.file=/etc/prometheus/prometheus.yml'  grafana:    image: grafana/grafana    container_name: grafana    restart: always    hostname: grafana    volumes:      - /opt/docker_compose/monitor/grafana/grafana.ini:/etc/grafana/grafana.ini    ports:      - "3000:3000"      alertmanager:    image: prom/alertmanager:latest    container_name: alertmanager    hostname: alertmanager    restart: always    volumes:      - /opt/docker_compose/monitor/altermanager/alertmanager.yml:/etc/alertmanager/alertmanager.yml    ports:      - "9093:9093"    prometheus-webhook-alert:    image: timonwong/prometheus-webhook-dingtalk:v1.3.0    container_name: prometheus-webhook-alertmanagers    hostname: webhook-alertmanagers    restart: always    volumes:      - /opt/docker_compose/monitor/prometheus-webhook-dingtalk/config.yml:/etc/prometheus-webhook-dingtalk/config.yml      - /etc/localtime:/etc/localtime    ports:      - "8060:8060"    entrypoint: /bin/prometheus-webhook-dingtalk   --config.file=/etc/prometheus-webhook-dingtalk/config.yml  --web.enable-ui

这里我的alter没有用grafana的，而是结合altermanager和 prometheus-webhook-dingtalk实现的钉钉告警。关于prometheus、altermanager、grafana都是常规配置大家可以找模板然后根据自己的需求修改，唯一需要说明的就是prometheus-webhook-dingtalk，虽然github上说明可以配置通知模版，但最新版本的，我怎么修改也不成，是个问题。需要观察以后版本会不会好，或者直接上手改它的go代码。

skywalking

version: '3.3'services:  elasticsearch:    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.0    container_name: elasticsearch    restart: always    ports:      - 9200:9200      - 9300:9300    environment:      - discovery.type=single-node      - bootstrap.memory_lock=true    network_mode: bridge    volumes:      - /data/docker_compose/skywalking/es/config/jvm.options:/usr/share/elasticsearch/config/jvm.options:rw      - /data/docker_compose/skywalking/es/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml      - /data/docker/elk/elk_elastic/data:/usr/share/elasticsearch/data:rw    ulimits:      memlock:        soft: -1        hard: -1  oap:    image: apache/skywalking-oap-server:8.1.0-es7    container_name: oap    depends_on:      - elasticsearch    links:      - elasticsearch    network_mode: bridge    restart: always    ports:      - 11800:11800      - 12800:12800    environment:      SW_ES_USER: elastic      SW_ES_PASSWORD: oasises      SW_STORAGE: elasticsearch7      SW_STORAGE_ES_CLUSTER_NODES: elasticsearch:9200      SW_TRACE_SAMPLE_RATE: 8000  ui:    image: apache/skywalking-ui:8.1.0    container_name: ui    network_mode: bridge    depends_on:      - oap    links:      - oap    restart: always    ports:      - 8083:8080    environment:      SW_OAP_ADDRESS: oap:12800

注意： es的详细配置文件需要你自己写哈。

kibana(ELK)
