这是因为之前的容器虽然没有运行起来，但是已经创建了，把它删除掉

可以看到容器成功启动
3.2创建方法二
创建docker-compose.yml文件，并在该文件所在的文件夹目录下运行docker-compose up -d 需要事先安装docker-compose安装docker-compose
Try fixing it: Make sure GitLab is running; Check the gitlab-shell configuration file: sudo -u git -H editor /opt/gitlab/embedded/service/gitlab-shell/config.yml Please fix the error above and rerun the checks.
查看上述配置文件，查找错误原因

访问GitLab失败错误
虽然容器启动成功，但是却没办法根据ip:port访问gitlab
启动一个tomcat容器测试端口
拉取tomcat镜像
1
docker pull tomcat:jdk8-openjdk
为了测试8088端口是否可用，先把gitlab的容器暂停
1
docker stop gitlab
启动tomcat容器，并将tomcat容器的8080端口映射到宿主机的8088端口

一切正常，访问ip:8088，还是和以前一样访问不了
开启防火墙并打开端口
因为之前系统的防火墙一直是关闭的并且其它的服务能正常访问，所以没有怀疑是防火墙的问题

一切正常
我再次换成tomcat容器进行测试，发现8088端口访问不了了。
但是在宿主机内ping本机是可以的
