Docker部署Sentinel

制作镜像

准备Dockerfile制作镜像sentinel-dashboard:latest

FROM maven:3.8-openjdk-8-slim as build
WORKDIR /app
COPY settings.xml /app/settings.xml
RUN sed -i 's/deb.debian.org/mirrors.aliyun.com/g' /etc/apt/sources.list && \
    sed -i 's/security.debian.org/mirrors.aliyun.com/g' /etc/apt/sources.list && \
    apt-get update && \
    apt-get upgrade -y && \
    apt-get install -y git && \
    git clone https://github.com/alibaba/Sentinel.git && \
    cd Sentinel/sentinel-dashboard && \
    /usr/share/maven/bin/mvn -s /app/settings.xml clean package -Dmaven.test.skip=true && \
    cp target/sentinel-dashboard.jar /app/sentinel-dashboard.jar

FROM ccr.ccs.tencentyun.com/fenston/openjdk:8-jdk-slim
ENV sentinel_home /home/sentinel
WORKDIR $sentinel_home
COPY --from=build /app/sentinel-dashboard.jar $sentinel_home/sentinel-dashboard.jar
RUN chmod -R +x $sentinel_home/sentinel-dashboard.jar
EXPOSE 8088
ENTRYPOINT ["/bin/sh", "-c", "java -jar $sentinel_home/sentinel-dashboard.jar --server.port=8088"]

使用打包命令:

docker build -t sentinel-dashboard:latest .

创建 docker-compose.yml

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

version: '3.1'
services:
  sentinel:
    restart: always
    image: ccr.ccs.tencentyun.com/fenston/sentinel-dashboard:1.8.4
    hostname: vm-sentinel
    container_name: sentinel
    environment:
      TZ: Asia/Shanghai
      LANG: en_US.UTF-8
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /etc/timezone:/etc/timezone:ro
    ports:
      - 8088:8088

启动镜像:

docker-compose up -d
