python - 将 watchman 安装到 Python docker 容器中时出错

Question

如何将 watchman 安装到我的 python docker 容器中？我已经尝试按照 watchman documentation 中的描述从源代码安装它但没有运气。这是我的 Dockerfile:

FROM python:3.9

# install watchman
RUN git clone https://github.com/facebook/watchman.git -b v4.9.0 --depth 1 && \
  cd watchman && \
  ./autogen.sh && \
  ./configure && \
  make && \
  make install

这是我尝试构建图像时的错误:

$ docker image build --tag pythonwatchman .
...

#5 143.0   CXX      root/watchman-watchlist.o

#5 146.8 make[1]: Leaving directory '/watchman'
#5 146.8 make: *** [Makefile:1264: all] Error 2

有什么办法可以解决这个问题吗？或者有没有更好的方法将 watchman 安装到这个容器中？

Answer 1

Or is there a better way to install watchman into this container?

是的，您可以直接将他们预编译的二进制文件安装到容器中，无需从源代码构建，参见this .

接下来是一个完整的解决方案，仅供引用。

Docker 文件:

FROM python:3.9

ARG WM_VERSION=v2021.03.01.00

# install watchman
RUN wget https://github.com/facebook/watchman/releases/download/$WM_VERSION/watchman-$WM_VERSION-linux.zip && \
unzip watchman-$WM_VERSION-linux.zip && \
cd watchman-$WM_VERSION-linux && \
mkdir -p /usr/local/{bin,lib} /usr/local/var/run/watchman && \
cp bin/* /usr/local/bin && \
cp lib/* /usr/local/lib && \
chmod 755 /usr/local/bin/watchman && \
chmod 2777 /usr/local/var/run/watchman && \
cd .. && \
rm -fr watchman-$WM_VERSION-linux.zip watchman-$WM_VERSION-linux

验证:

$ docker build -t abc:1 .
$ docker run --rm -it abc:1 watchman --version
20210222.215625.0

你可以看到我们现在已经可以运行 watchman 命令了。

顺便说一句，所有预定义的二进制文件都可以在 github 中找到.
