Dockerfile在不同发行版的写法

我个人比较喜欢ubuntu，cento替代方案Almalinux

ubuntu

####################################################
# --no-cache 表示不缓存
# -t ubuntubt:1.0 表示镜像名字ubuntubt版本1.0
# docker build --no-cache -t ubuntubtxx:1.0 .
#---------------------------------------------------
# 使用 distrobox 创建镜像，MYubuntuBT是镜像名字
# distrobox create --image ubuntubt:1.0 MYubuntuBT
#---------------------------------------------------
# 进入 MYubuntuBT容器
# distrobox enter MYubuntuBT
#---------------------------------------------------
# 在容器执行这条命令 把程序快捷启动发送到开始菜单，AppName程序名字
# distrobox-export --app AppName
