Docker部署Nacos

准备存储卷

mkdir conf logs

准备配置文件

nacos持久化配置外部mysql，需要提前创建nacos数据库

nacos.env

PREFER_HOST_MODE=hostname
MODE=standalone
SPRING_DATASOURCE_PLATFORM=mysql
MYSQL_SERVICE_HOST=10.0.32.2
MYSQL_SERVICE_DB_NAME=nacos
MYSQL_SERVICE_PORT=3306
MYSQL_SERVICE_USER=nacos
MYSQL_SERVICE_PASSWORD=nacos

JVM_XMX=128m
JVM_XMN=32m

### The auth system to use, currently only 'nacos' is supported:
nacos.core.auth.system.type=${NACOS_AUTH_SYSTEM_TYPE:nacos}


### The token expiration in seconds:
nacos.core.auth.default.token.expire.seconds=${NACOS_AUTH_TOKEN_EXPIRE_SECONDS:18000}

### The default token:
nacos.core.auth.default.token.secret.key=${NACOS_AUTH_TOKEN:SecretKey012345678901234567890123456789012345678901234567890123456789}

### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.
nacos.core.auth.caching.enabled=${NACOS_AUTH_CACHE_ENABLE:false}
nacos.core.auth.enable.userAgentAuthWhite=${NACOS_AUTH_USER_AGENT_AUTH_WHITE_ENABLE:false}

创建 docker-compose.yml

创建文件: /usr/local/nacos/docker-compose.yml, 内容如下:

version: '3.8'
services:
  nacos:
    restart: always
    image: nacos/nacos-server:v2.0.4
    hostname: vm-nacos
    container_name: nacos
    environment:
      TZ: Asia/Shanghai
      LANG: en_US.UTF-8
    env_file:
      -  ./conf/nacos.env
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /etc/timezone:/etc/timezone:ro
      - ./conf/custom.properties:/home/nacos/init.d/custom.properties
      - ./conf/application.properties:/home/nacos/conf/application.properties
      - ./logs/:/home/nacos/logs
    ports:
      - 8848:8848
