一 背景介绍
先来看一下我们熟悉的第一代 spring cloud 的组件
| 组件名称 | 功能 |
| Ribbon | 客户端负载均衡器 |
| Eureka | 服务治理（注册、发现......） |
| Hystrix | 服务之间远程调用时的熔断保护 |
| Feign | 通过定义接口的方式直接调用其他服务的 API |
| Zuul | 分布式配置组件 |
| Config | 服务网关 |
| Sleuth | 用于请求链路跟踪 |
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
| 第一代组件 | 第二代组件 |
| Eureka | Nacos |
| Config | Apollo |
| Zuul | spring cloud gateway |
| Hystrix | Sentinel |
再加上我们常用的组件
| 组件 | 功能 |
| XXL-Job | 分布式定时任务中心 |
| Redis | 分布式缓存 |
| Rocket-MQ | 消息队列 |
| Seata | 分布式事务 |
| ELK | 日志处理 |
| Skywalking | 调用链监控 |
| Prometheus | metrics监控 |
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.conf brokerClusterName = DefaultCluster brokerName = broker-abroker Id = 0 deleteWhen = 04 fileReservedTime = 48 brokerRole = ASYNC_MASTER flushDiskType = ASYNC_FLUSH ### ./data1/broker/conf/broker.conf brokerClusterName = Default ClusterbrokerName = broker-bbroker Id = 0 deleteWhen = 04 fileReservedTime = 48 brokerRole = ASYNC_MASTER flushDiskType = 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.jar EXPOSE 8080 #指定容器启动程序及参数 <ENTRYPOINT> "<CMD>" 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)
version: '2' services: elk-logstash: image: docker.elastic.co/logstash/logstash:7.5.0 container_name : elk_logstash hostname: elk_logstash stdin_open: true tty: true ports: - "5000:5000/udp" - 5001:5001 command: logstash --path.settings /etc/logstash -f /etc/logstash/conf.d/logstash.conf external_links: - elasticsearch network_mode: bridge volumes: - /data1/docker/elk/elk_logstash/conf.d:/etc/logstash/conf.d - /data1/docker/elk/elk_logstash/heapdump.hprof:/usr/share/logstash/heapdump.hprof -rw - /data1/docker/elk/elk_logstash/gc.log:/usr/share/logstash/gc.log -rw elk-kibana: image: docker.elastic.co/kibana/kibana:7.5.0 container_name : elk_kibana hostname: elk_kibana stdin_open: true tty: true ports: - 5601:5601 external_links: - elasticsearch network_mode: bridge volumes: - /data1/docker/elk/elk_kibana/config/kibana.yml:/usr/share/kibana/config/kibana.yml environment: - ELASTICSEARCH_URL=http://elasticsearch:9200
- 由于ES一般我们会建集群，这里忽略ES容器
- logstash和kibana的相关配置也可从官网找到模版进行修改
