如何在docker中运行chromedp

我正试着在码头上跑步。 我的：

Dockerfile：

FROM golang:latest as build-env
RUN mkdir $GOPATH/src/app
WORKDIR $GOPATH/src/app
ENV GO111MODULE=on
COPY go.mod .
COPY go.sum .
COPY main.go .
RUN go mod download
RUN go build -o /root/app

FROM chromedp/headless-shell
COPY --from=build-env /root/app /
CMD ["/app"]

当我运行它时：

docker-compose build
docker-compose up

它输出：

app_1  | [1129/192523.576726:WARNING:resource_bundle.cc(426)] locale_file_path.empty() for locale 
app_1  | [1129/192523.602779:WARNING:resource_bundle.cc(426)] locale_file_path.empty() for locale

所以它不会运行我的go应用程序。我希望

chromedp/headlesshell

包含google chrome，我的golang应用程序将成功使用它

更新1 我缺少目录：

RUN mkdir -p /headless-shell/swiftshader/ \
    && cd /headless-shell/swiftshader/ \
    && ln -s ../libEGL.so libEGL.so \
    && ln -s ../libGLESv2.so libGLESv2.so

现在有以下输出，我的应用程序仍然没有运行：

app_1  | [1202/071210.095414:WARNING:resource_bundle.cc(426)] locale_file_path.empty() for locale 
app_1  | [1202/071210.112632:WARNING:resource_bundle.cc(426)] locale_file_path.empty() for locale 
app_1  | 
app_1  | DevTools listening on ws://0.0.0.0:9222/devtools/browser/86e31db1-3a17-4da6-9e2f-696647572492
app_1  | [1202/071210.166158:WARNING:resource_bundle.cc(426)] locale_file_path.empty() for locale 
app_1  | [1202/071210.186307:WARNING:resource_bundle.cc(426)] locale_file_path.empty() for locale 

更新2 看起来

CMD[“/app”]

没有运行我的main.go文件，因为它没有打印其中的任何行。 当我手动运行它时：

$ /usr/local/bin/docker exec -ti chromedp_docker_app_1 /bin/bash

root@0c417fd159a2:/# /app
2019/12/02 07:40:34 app is running

我看到

google-chrome

应用程序仍然不存在，嗯…

您缺少一些东西，首先您需要在您的容器中运行google-headless-chrome。您可以使用以下Dockerfile

FROM golang:1.12.0-alpine3.9

RUN apk update && apk upgrade && apk add --no-cache bash git && apk add --no-cache chromium

# Installs latest Chromium package.
RUN echo @edge http://nl.alpinelinux.org/alpine/edge/community >> /etc/apk/repositories \
    && echo @edge http://nl.alpinelinux.org/alpine/edge/main >> /etc/apk/repositories \
    && apk add --no-cache \
    harfbuzz@edge \
    nss@edge \
    freetype@edge \
    ttf-freefont@edge \
    && rm -rf /var/cache/* \
    && mkdir /var/cache/apk

RUN go get github.com/mafredri/cdp


CMD chromium-browser --headless --disable-gpu --remote-debugging-port=9222 --disable-web-security --safebrowsing-disable-auto-update --disable-sync --disable-default-apps --hide-scrollbars --metrics-recording-only --mute-audio --no-first-run --no-sandbox

我正在使用CDP，对我来说更加健壮和有趣！

您找到解决方案了吗？我也有同样的问题@阿斯普里特的回答对我没有帮助

FROM golang:1.12.0-alpine3.9

RUN apk update && apk upgrade && apk add --no-cache bash git && apk add --no-cache chromium

# Installs latest Chromium package.
RUN echo @edge http://nl.alpinelinux.org/alpine/edge/community >> /etc/apk/repositories \

    && rm -rf /var/cache/* \
