Linux useradd和-u选项导致docker挂起

我有以下docker文件

FROM ubuntu:18.04

ARG user_id
ARG user_gid

# Essential packages for building on a Ubuntu host
# https://docs.yoctoproject.org/ref-manual/system-requirements.html#ubuntu-and-debian
# Note, we set DEBIAN_FRONTEND=noninteractive prior to the call to apt-get
# install because otherwise we'll get prompted to select a timezone when the
# tzdata package gets included as a dependency.
RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y    \
    gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential \

# Add a user and set them up for passwordless sudo. We're using the same user
# ID and group numbers as the host system. This allows us to give the yocto
# user ownership of files and directories in the poky volume we're going to add
# without needing to change ownership which would also affect the host system.
RUN groupadd -g $user_gid yoctouser
RUN useradd -m yoctouser -u $user_id -g $user_gid
    #echo "yoctouser ALL=(ALL:ALL) NOPASSWD:ALL" | tee -a /etc/sudoers

USER yoctouser
WORKDIR /home/yoctouser

ENV LANG=en_US.UTF-8

CMD /bin/bash

useradd命令挂起，特别是

-u

选项。如果我删除

-u$user\u id

一切正常。此外，docker正在填充我的磁盘<代码>/var/lib/docker/overlay2/在几秒钟后将

-u

选项添加到千兆字节之前，从852MB变为852MB。如果我不杀死它，它会完全填满我的磁盘，最后我不得不停止docker守护进程并手动删除overlay2目录中的文件夹

为什么指定此uid可能是一个问题

下面是我编写的python脚本的相关部分，用于驱动此过程，以便您可以看到我如何获取用户ID并将其传递给

docker build

def build_docker_image():
    print("Building a docker image named:", DOCKER_IMAGE_NAME)
    USERID_ARG  = "user_id=" + str(os.getuid())
    USERGID_ARG = "user_gid=" + str(os.getgid())
    print(USERID_ARG)
    print(USERGID_ARG)
    try:
        subprocess.check_call(['docker', 'build',
                               '--build-arg', USERID_ARG,
                               '--build-arg', USERGID_ARG,
                               '-t', DOCKER_IMAGE_NAME, '.',
                               '-f', DOCKERFILE_NAME])
    except:
        print("Failed to create the docker image")
        sys.exit(1)

FWIW，在我的系统上

user_id=1666422094
user_gid=1666400513

---

我正在运行Docker版本20.10.5，在Ubuntu 18.04主机上构建55c4c88。

我需要在调用

useradd

时使用

/
--no log init
选项来解决与处理大UID相关的问题

我的最后一个dockerfile看起来像

FROM ubuntu:18.04

ARG user_id
ARG user_gid

    echo "yoctouser ALL=(ALL:ALL) NOPASSWD:ALL" | tee -a /etc/sudoers

USER yoctouser
WORKDIR /home/yoctouser

CMD ["/bin/bash"]

提到我需要使用带有长UID的
-l
标志，因为。我很快就会试试这个。
