一. Dockerfile

FROM sonatype/nexus3:3.9.0-01

LABEL Description="sonatype/nexus3:3.9.0-01做成的org.pzy/nexus3.9:1.0"  Version="1.0"

# 将时区设置为东八区
USER root
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

# 切换回nexus用户
USER nexus

解决问题

基于官方镜像, 将系统时区改为东八区

二. 打造自己的启动脚本

# 重复执行start命令并不会重复启动

    # 说明backend网络不存在,创建backend网络
    echo "自动创建backend网络!"
    docker network create backend
  fi
  containerId=`docker ps -a | grep "nexus3" | grep "Up" | awk '{print $1}'`

  if [ -z "$containerId" ]; then
    # 容器id为空,说明nexus未启动,或已停止
    echo "容器nexus3状态: "`docker ps -a | grep "nexus3"`

    containerId=`docker ps -a | grep "nexus3" | grep "Exited" | awk '{print $1}'`
    if [ -n "$containerId" ]; then

elif [ "$1" = "stop" ]; then
  if [ -n "$containerId" ]; then
