Sentinel制作Docker镜像

准备工作

sentinel-dashboard.jar
jdk-8u11-linux-x64.tar.gz

1.创建jar文件夹

mkdir jar

2.在jar文件夹下创建1.8.1文件夹

mkdir 1.8.1

3.将sentinel-dashboard.jar放到1.8.1文件夹下

4.将jdk-8u11-linux-x64.tar.gz放在与jar文件夹同级的目录下

 5.编写Dockerfile文件

vim Dockerfile

6.Dockerfile文件内容如下

FROM centos:7.9.2009
MAINTAINER kim "xxx@163.com"

RUN set -x \
    && mkdir -p /data/sentinel \
    && cd /data/sentinel \
    && mkdir -p logs \
	&& cd logs \
	&& touch start.out \
	&& ln -sf /dev/stdout start.out \
	&& ln -sf /dev/stderr start.out \
    && ln -snf /usr/share/zoneinfo/$TIME_ZONE /etc/localtime && echo '$TIME_ZONE' > /etc/timezone \

# 允许挂载该目录
VOLUME /data/sentinel/logs 

# 添加jdk、sentinel的jar包
ADD jdk-8u11-linux-x64.tar.gz /usr/local
ADD ./jar/1.8.1/sentinel-dashboard.jar  /data/sentinel-dashboard/sentinel-dashboard.jar

# set environment
ENV BASE_DIR="/data/sentinel" \
    JAVA_HOME="/usr/local/jdk1.8.0_11" \
    JAVA="/usr/local/jdk1.8.0_11/bin/java" \
    JVM_XMS="512m" \
    JVM_XMX="512m" \
    JVM_XMN="256m" \
    TIME_ZONE="Asia/Shanghai" \
    SERVER_PORT="8080"

WORKDIR $BASE_DIR
EXPOSE 8080

#配置启动命令
CMD echo "$JAVA ${JAVA_OPT}" > ${BASE_DIR}/logs/start.out && nohup $JAVA ${JAVA_OPT} >> ${BASE_DIR}/logs/start.out 2>&1 < /dev/null

 7.构建镜像（注意：后边有一个点）

docker build -t sentinel-dashboard:1.8.1 .

8.编写docker-compose-sentinel.yml，docker-compose启动

version: '3'
services:
  sentinel:
    image: sentinel-dashboard:1.8.1
    container_name: sentinel
    restart: always
    volumes:
      - /data/sentinel-dashboard-docker/logs:/data/sentinel/logs 
    ports:
      - "8718:8080"
      - "8719:8719"
