问题1:启动nexus时，没有权限操作宿主机文件夹

docker run -d -p 8082:8082 -v /home/nexus-data/:/nexus-data/ --name nexus1 sonatype/nexus3

Warning:  Cannot open log file: ../sonatype-work/nexus3/log/jvm.log
Warning:  Forcing option -XX:LogFile=/tmp/jvm.log
Unable to update instance pid: Unable to create directory /nexus-data/instances
/nexus-data/log/karaf.log (No such file or directory)
Unable to update instance pid: Unable to create directory /nexus-data/instances
mkdir: cannot create directory '../sonatype-work/nexus3/log': Permission denied
mkdir: cannot create directory '../sonatype-work/nexus3/tmp': Permission denied
OpenJDK 64-Bit Server VM warning: Cannot open file ../sonatype-work/nexus3/log/jvm.log due to No such file or directory

解决方案： 修改宿主机文件夹权限

chmod 777 /home/nexus-data1

问题2:设置端口8082，拒绝访问

解决方案：修改nexus配置文件 nexus.properties

application-port=8082  #修改成自己想要的端口
