Python VS代码远程容器：外壳服务器终止（代码：126，信号：null）找不到用户xxx:passwd文件中没有匹配项

我正在尝试使用Visual Studio代码扩展远程容器从docker运行python代码。以下是Dockerfile：

FROM python:3.8-slim-buster

# Keeps Python from generating .pyc files in the container
ENV PYTHONDONTWRITEBYTECODE 1

# Turns off buffering for easier container logging
ENV PYTHONUNBUFFERED 1

ENV BLOB_CONTAINER_SAS_CONNECTION="secret"
ENV ROUND_LEVEL="0"
# Install pip requirements
ADD requirements.txt .
RUN python -m pip install -r requirements.txt



WORKDIR /app
COPY [ ".env", "/app"]
ADD /src/sample_code_round_data_docker.py /app

# Switching to a non-root user, please refer to https://aka.ms/vscode-docker-python-user-rights
ARG USERNAME=someuser
ARG USER_UID=1000
ARG USER_GID=$USER_UID

# Create the user
RUN groupadd --gid $USER_GID $USERNAME \
    && useradd --uid $USER_UID --gid $USER_GID -m $USERNAME \
    #
    # [Optional] Add sudo support. Omit if you don't need to install software after connecting.
    && apt-get update \
    && apt-get install -y sudo \
    && echo $USERNAME ALL=\(root\) NOPASSWD:ALL > /etc/sudoers.d/$USERNAME \
    && chmod 0440 /etc/sudoers.d/$USERNAME


# [Optional] Set the default user. Omit if you want to keep the default as root.
USER $USERNAME
# During debugging, this entry point will be overridden. For more information, please refer to https://aka.ms/vscode-docker-python-debug
CMD ["python", "sample_code_round_data_docker.py"] 

下面是.devcontainer.json：

{
    "name": "Existing Dockerfile",

    "context": "..",

    "dockerFile": "Dockerfile",

    "settings": { 
        "terminal.integrated.shell.linux": null
    },
    "extensions": [],
     "remoteUser": "someuser"
}

当我运行它时，它会抛出一个错误：

Shell server terminated (code: 126, signal: null)
unable to find user someuser: no matching entries in passwd file

在容器中搜索

passwd

文件时：

cat /etc/passwd

---

没有用户

someuser

我也有同样的问题。对我来说，一开始我忘记了创建vscode用户，所以我修改了映像以创建vscode用户，但是vscode没有更新以使用新映像

我必须手动删除vscode试图使用的（旧）容器。如果你去

远程容器：显示日志

您可以看到VSCode试图使用的容器的ID

然后，您可以使用以下方法杀死并移除容器：

docker kill $YOUR_ID_HERE
docker rm $YOUR_ID_HERE

---

然后告诉vscode再次尝试在远程容器中打开项目。它将被迫使用更新的图像创建新容器。

如何创建用户？
