我已经在imagick git存储库上发布了这个问题,但是它的用户基础非常小,所以我希望从这里得到一些帮助。我已经尝试了几天了,现在使用官方的goLang dockerfile为我正在做的一个项目导入https://github.com/gographics/imagick到Docker,但是没有成功。由于这个软件包不流行,运行apt-get将不起作用。我(犹豫地)尝试将文件添加到容器中,但这不起作用。以下是我构建的DockerFile和它产生的错误:= = = DOCKERFILE = = =
# 1) Use the official go docker image built on debian.
FROM golang:latest
# 2) ENV VARS
ENV GOPATH $HOME/<PROJECT>
ENV PATH $HOME/<PROJECT>/bin:$PATH
# 3) Grab the source code and add it to the workspace.
ADD . /<GO>/src/<PROJECT>
ADD . /<GO>/gopkg.in
# Trying to add the files manually... Doesn't help.
ADD . /opt/local/share/doc/ImageMagick-6
# 4) Install revel and the revel CLI.
#(The commented out code is from previous attempts)
#RUN pkg-config --cflags --libs MagickWand
#RUN go get gopkg.in/gographics/imagick.v2/imagick
RUN go get github.com/revel/revel
RUN go get github.com/revel/cmd/revel
# 5) Does not work... Can't find the package.
#RUN apt-get install libmagickwand-dev
# 6) Get godeps from main repo
RUN go get github.com/tools/godep
# 7) Restore godep dependencies
WORKDIR /<GO>/src/<PROJECT>
RUN godep restore
# 8) Install Imagick
#RUN go build -tags no_pkgconfig gopkg.in/gographics/imagick.v2/imagick
# 9) Use the revel CLI to start up our application.
ENTRYPOINT revel run <PROJECT> dev 9000
# 10) Open up the port where the app is running.
EXPOSE 9000

这允许我构建docker容器,但是当我试图运行它时,我在kinematic的日志中得到以下错误:

大多数基本映像都删除了包列表,以避免减小映像大小。因此,为了使用apt-get
安装某些东西,您首先需要更新包列表,然后安装您希望安装的任何包。然后,在安装包之后,删除运行apt的所有副作用,以避免用不需要的文件污染映像(所有这些都必须作为单个RUN
命令)。
下面的Dockerfile应该可以做到:
FROM golang:latest
RUN apt-get update # update package lists
&& apt-get install -y libmagickwand-dev # install the package
&& apt-get clean # clean package cache
&& rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* # remove everything else
RUN go get gopkg.in/gographics/imagick.v2/imagick
请记住将-y
添加到apt-get install
,因为docker build
是不可交互的。
