ImageMagick无法从Docker容器中从HTTPS获取文件
ImageMagick无法从Docker容器中从HTTPS获取文件
提问于 2022-10-11 12:43:49
我试图在码头容器中使用ImageMagick 7。不过，它没有安装任何委托，尽管我添加了libpng-dev。当我尝试使用以下命令从https获取容器内的图像时：
magick https://www.nasa.gov/sites/default/files/thumbnails/image/moon_mosaic.png ./test.png我收到这样的信息：
magick: no decode delegate for this image format `DAT' @ error/constitute.c/ReadImage/738.这是没有意义的，因为它是一个PNG图像，而不是一个DAT文件。
在这里，我的Dockerfile：
FROM debian:bullseye-slim
ARG IM_VERSION="7.1.0-37"
ARG IM_BUILD_FLAGS="--enable-shared --disable-static --without-modules --enable-delegate-build --disable-docs --with-heic=yes"
WORKDIR /app
RUN apt-get update && apt-get install -y wget && \
apt-get install -y build-essential curl libpng-dev && \
wget https://github.com/ImageMagick/ImageMagick/archive/refs/tags/${IM_VERSION}.tar.gz && \
tar xzf ${IM_VERSION}.tar.gz && \
rm ${IM_VERSION}.tar.gz && \
apt-get clean && \
apt-get autoremove
WORKDIR /app/ImageMagick-${IM_VERSION}
RUN sh ./configure ${IM_BUILD_FLAGS} && make -j && make install && ldconfig /usr/local/lib/在这里，构建ImageMagick的配置部分的输出：

当我在Docker容器之外使用ImageMagick时，它没有问题。我不知道问题是什么，也不知道为什么不配置代表。遗憾的是，我无法用ImageMagick 7安装apt。

尝试将pkg-config (可能还包括autoconf )添加到先决条件包列表中。ImageMagick在查找和配置这些助手(特别是PNG委托)方面要好得多：
RUN apt-get update && apt-get install -y wget && \
apt-get install -y autoconf pkg-config ...实际上，高寒码头图像对于ImageMagick来说是辉煌的。它非常流行，非常小，包括大量的代表：
docker run --rm -it -v "$(pwd)":/work -w /work alpine:latest
/work # apk add --no-cache imagemagick
...
... output, output, output
... and then around 4 seconds later
...
/work # magick identify -version
