无法找到用户root：Docker中的passwd文件中没有匹配的条目

docker exec -it -u root ${DOCKER_CONTAINER} bash

使用此命令,我可以像往常一样访问,但在运行脚本来提取和压缩日志文件后,我再也无法访问该容器了.

摘自’清理脚本’

这是第一个失败点,脚本每周运行一次(由Jenkins安排).

docker cp ${CLEAN_UP_SCRIPT} ${DOCKER_CONTAINER}:/tmp/${CLEAN_UP_SCRIPT}
if [ $? -eq 0 ]; then
  docker exec -it -u root ${DOCKER_CONTAINER} bash -c "cd ${LOG_DIR} && /tmp/compressOldLogs.sh ${ARCHIVE_FILE}"
fi

当脚本向Bitbucket容器执行这两行时,结果是：

unable to find user root: no matching entries in passwd file

它在’docker cp’命令上失败了,但只在Bitbucket容器上失败了.脚本运行后,使用’bitbucket'(在Dockerfile中定义)和’root’用户都无法访问容器.

我能够将/ etc / passwd复制出容器,它按预期包含所有用户.当尝试通过uid访问时,我收到以下错误：

rpc error: code = 2 desc = oci runtime error: exec failed: process_linux.go:75: starting setns process caused "fork/exec /proc/self/exe: no such file or directory"

附加信息：

> Docker版本1.12.0,构建8eab29e
> docker-compose版本1.8.0,build f3628c7
>所有容器都在运行,甚至Bitbucket在发生问题后照常工作
>重新启动容器后问题消失

看来这个bug可能比两年多了！
