jenkins – Docker：无法找到root用户：passwd文件中没有匹配

我有多个Atlassian产品的容器; JIRA,Bitbucket和Confluence.当我试图访问我经常使用的运行容器时：

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,但只是在Bitbucket容器上.脚本运行后,容器无法访问“bitbucket”(在Dockerfile中定义)和“root”用户.

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"

>所有容器都在运行,甚至Bitbucket在问题发生后照常工作
>重新启动容器后问题消失
