python - 无法使用 sasl python 模块构建 docker 镜像

Question

我正在尝试在我的 mac (High Sierra) 上构建一个包含 Python 2 的 docker 镜像。这是 docker 文件。 (构建命令:docker build -t integration_test .)

FROM python:2

WORKDIR /usr/src/app

COPY requirements.txt ./

RUN pip install -r requirements.txt

COPY . .

CMD [ "nosetests" ]

这是requirements.txt

的内容

nose
pyhive
thrift
sasl
thrift_sasl
python-dateutil
future
six>=1.7.2

当我尝试构建 docker 镜像时，出现以下错误。

我见过类似的问题here它讨论了在主机操作系统上安装依赖库。我想知道如何在 docker image/container 上完成此操作。

有没有人遇到过这个问题？关于如何解决这个问题有什么建议吗？

您需要将 libsasl2-dev 安装到您的 Docker 镜像。

以最简单的形式，在 pip install 之前将以下行添加到您的 Dockerfile 中:

RUN apt-get update && apt-get install libsasl2-dev
