Today, the editor will share with you the relevant knowledge points about how docker builds the nacos+nginx+mysql+redis+springboot project. The content is detailed and the logic is clear. I believe most people still know too much about this, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Please install docker and docker-compose in advance and configure your own image acceleration. Note in advance: my entire project is actually built twice, the first deployment is only: nginx+mysql+redis+springboot project, nacos is later added to entertain yourself.

A.docker-compose.yml file

Version: "3" services: nginx: # service name, user-defined image: nginx:latest # image version ports:-80:80 # exposed port volumes: # mount-/ root/nginx/html:/usr/share/nginx/html-/ root/nginx/nginx.conf:/etc/nginx/nginx.conf privileged: true # this is required Solve the problem of file call authority of nginx mysql: image: mysql:5.7.27 ports:-3306 environment: # specify the password of user root-MYSQL_ROOT_PASSWORD= redis: ports:-6379 image 6379 image: redis:latest vueblog: image: vueblog:latest build:. # means to start building an image with the Dockerfile in the current directory:-81:81 depends_on: # depends on mysql and redis, but you can leave it empty. By default, it has been indicated that you can-mysql-redis nacos1: hostname: nacos1 container_name: nacos1 image: nacos/nacos-server:latest volumes: # need to add a plug-in for mysql8 # -. / nacos/plugins/mysql/:/home/nacos/plugins/mysql/ # to map the log file-/ root/nacos1:/home/nacos/logs # to the configuration text / root/nacos1/custom.properties:/home/nacos/init.d/custom.properties environment: # set the environment variable Equivalent to-e-JVM_XMS=512m-JVM_XMX=512m-JVM_XMN=128m #-MODE=standalone # standalone version of ports:-"8848 JVM_XMN=128m 8848" env_file: # Cluster profile-/ root/nacos1/nacos-hostname.env restart: always depends_on:-mysql in the docker run command

B.springboot configuration (your own project)

Both the mysql and redis configurations in the configuration use the service name instead of the ip address

Server: port: 81spring: servlet: multipart: max-file-size: 10MB max-request-size: 10MB profiles: active: dev # mysql configuration datasource: url: jdbc:mysql://mysql:3306/blog4?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=UTF-8 username: password: # schema: classpath:springbootsecurityauth.sql sql-script-encoding: utf-8 initialization-mode: always driver-class-name : com.mysql.cj.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource # initialization size Min, Max initialSize: 1 minIdle: 3 maxActive: 20 # configuration get connection wait timeout maxWait: 60000 # configure how often to detect idle connections that need to be closed, in milliseconds timeBetweenEvictionRunsMillis: 60000 # configure the minimum survival time of a connection in the pool Unit: millisecond minEvictableIdleTimeMillis: 30000 validationQuery: select'x 'testWhileIdle: true testOnBorrow: false testOnReturn: false # Open PSCache and specify the size of PSCache on each connection poolPreparedStatements: true maxPoolPreparedStatementPerConnectionSize: 20 # configure the filters of monitoring statistics interception. After removing it, the monitoring interface sql cannot be counted. 'wall' is used for firewalls, and slf4j filters: stat,wall,slf4j # turns on the mergeSql function through the connectProperties attribute Slow SQL recording connectionProperties: druid.stat.mergeSql=true Druid.stat.slowSqlMillis=5000 redis: database: 6 host: redis port: 6379 timeout: 5000s # connection timeout (Ms) jedis: pool: max-active: 20 # maximum number of connections in connection pool (using negative values for no limit) max-idle: maximum idle connections in 8 # connection pool max-wait:-1s # connection pool maximum blocking wait time Between (using negative values for unlimited) min-idle: minimum idle connections in the 0 # connection pool password: # rootroot

C.Dockerfile file

FROM java:8EXPOSE 81ADD vueblog.jar app.jarRUN bash-c 'touch / app.jar'ENTRYPOINT ["java", "- jar", "/ app.jar"]

d. Package the springboot project and name it the service name in the configuration

e. Create a folder or file under the corresponding directory

-/ root/nginx/html

-/ root/nginx/nginx.conf

# user root;worker_processes 1 server nacos1:8848 weight=1 max_fails=2 fail_timeout=10s; events {worker_connections 1024;} http {server nacos1:8848 weight=1 max_fails=2 fail_timeout=10s; 65; # the ip: port of nacos is configured here, because nginx and nacos are on the same network, and the service name can be used to access upstream nacos {server nacos1:8848 weight=1 max_fails=2 fail_timeout=10s; # port # server nacos3:8848 weight=1 max_fails=2 fail_timeout=10s;} server {listen 80; server_name localhost; location / {root / usr/share/nginx/html/front; try_files $uri $uri/ / index.html last; # Don't forget this index index.html index.htm } location / admin {alias / usr/share/nginx/html/admin; expires 1d; index index.html; autoindex on;} location / nacos {proxy_pass http://nacos; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr Proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header REMOTE-HOST $remote_addr; add_header X-Cache $upstream_cache_status; add_header Cache-Control no-cache;} error_page 500502 503 504 / 50x.html; location = / 50x.html {root html;}}

-/ root/nacos1

# Map the configuration file

-/ root/nacos1/custom.properties

# spring.security.enabled=false#management.security=false#security.basic.enabled=false#nacos.security.ignore.urls=/**#management.metrics.export.elastic.host= http://localhost:9200# metrics for prometheusmanagement.endpoints.web.exposure.include=*# metrics for elastic search#management.metrics.export.elastic.enabled=false#management.metrics.export.elastic.host= http://localhost:9200# metrics for influx#management.metrics.export.influx.enabled=false#management.metrics.export.influx.db=springboot#management.metrics.export.influx. Uri= http://localhost:8086#management.metrics.export.influx.auto-create-db=true#management.metrics.export.influx.consistency=one#management.metrics.export.influx.compressed=true

-/ root/nacos1/nacos-hostname.env

Configure database information for nacos

# nacos dev envPREFER_HOST_MODE=hostnameNACOS_SERVERS=nacos1:8848MYSQL_SERVICE_HOST=mysqlMYSQL_SERVICE_DB_NAME=nacosMYSQL_SERVICE_PORT=3306MYSQL_SERVICE_USER=MYSQL_SERVICE_PASSWORD=JVM_XMS=512mJVM_XMX=512mJVM_XMN=256mJVM_MS=64mJVM_MMS=128m

The final directory structure

Run mysql instances first (do not docker-compose up all instances directly) docker-compose up-d mysql

f. Since my nacos was added later, you can add the nacos database to the mysql container in advance and then start it (if you don't have a database, please add it in advance)

Start

Docker-compose up

Stop it
