我正在为类似Debian的发行版编写软件包的维护人员的码头形象。这些映像是从相应的Debian类发行版的官方映像中派生出来的,方法是添加维护所需的包,并从几个有用的挂载卷开始,以便从用户的环境中获取各种配置项,而不是保存在容器中。
当我从那个映像启动一个shell并执行一个apt-src build来准备一个包时,操作通常会启动,但是容器和tty之间的连接会莫名其妙地下降。使用docker ps -a检查容器的状态显示它是Exited (0)。这是非常奇怪的,因为它意味着在运行它的子命令时,某些东西会导致shell退出。
哪些步骤可以帮助我调试这种奇怪的行为,找出这里发生了什么,并最终修复它?
容器运行命令
我就是这样启动容器的:
docker run\
--interactive=true\
--tty=true\
--rm=false\
--volume "${maintainer_pkgdir}:${maintainer_docker_pkgdir}"\
--volume "${maintainer_srcdir}:${maintainer_docker_srcdir}"\
--volume "${maintainer_confdir}:${maintainer_docker_confdir}"\
"${maintainer_repository}/${maintainer_image}"会议记录
会话由两个命令apt-src install bmake和apt-src build bmake组成
% apt-src install bmake

将程序附加到tty似乎是一种不完全可靠的操作,这意味着它只能在程序合理使用tty的假设下工作。
程序su因滥用tty连接而臭名昭著,因此,与其排除问题,不如避免使用su或任何其他滥用连接到的tty的程序。
