复制文件 - 在 Dockerfile 旁边 - 不起作用并阻止 docker 构建

Question

我正在尝试构建一个 docker 容器，其中包含 mlflow 服务器，并使用 poetry toml 文件进行依赖。（这两个 toml 完全相同，这只是一种尝试弄清楚的方法）
树：

├── docker-entrypoint.sh
├── Dockerfile
├── 文件
│ └── pyproject.toml
├── git.sh
├── pyproject.toml
└── README.md

如你所见，我的 toml 文件在 Dockerfile 旁边 COPY pyproject.toml ./ 不过还是不行

Dockerfile

FROM python:3.6.10-alpine3.10 as base
LABEL maintainer=""

ENV PYTHONFAULTHANDLER 1 
ENV    PYTHONHASHSEED random 
ENV    PYTHONUNBUFFERED 1

    && pip install poetry==${POETRY_VERSION} \
    && mkdir -p ${FILE_STORE}  \
    && mkdir -p ${ARTIFACT_STORE}\
    && python -m venv /venv

COPY  pyproject.toml ./
RUN poetry export -f requirements.txt | /venv/bin/pip install -r  --allow-root-install /dev/stdin 

COPY . .
RUN poetry build && /venv/bin/pip install dist/*.whl

FROM base as final

RUN apk add --no-cache libffi libpq
COPY --from=builder /venv /venv
COPY docker-entrypoint.sh ./

EXPOSE $SERVER_PORT

VOLUME ["${FILE_STORE}", "${ARTIFACT_STORE}"]

CMD ["./docker-entrypoint.sh"]

构建命令：

docker build - < Dockerfile

我收到这个错误：

Step 21/32 : COPY  pyproject.toml ./
COPY failed: stat /var/lib/docker/tmp/docker-builder335195979/pyproject.toml: no such file or   directory

如果我在第一个 COPY 之前添加 RUN pwd; ls，我将获得：

Answer 1

试试看 docker build -t test .

而不是 docker build - < Dockerfile

复制文件 - 在 Dockerfile 旁边 - 不起作用并阻止 docker 构建

COPY files - next to Dockerfile - don't work and block docker build

docker

dockerfile

mlflow

python-poetry
