node.js - Docker Node :Alpine-12: how to install Chromium 73 in Dockerfile?

Question

因为我想运行 Puppeteer@1.19 但在 page.pdf() 中遇到错误。

一些 blob 刚刚提到将 Chromium 从版本 76 降级到 73。如何使用 node:alpine-12 在 Dockerfile 中执行此操作？谢谢

以下是我的设置(chromium 版本是 76):

FROM node:12-alpine
########## 
## Setting for using Puppeteer (for using node:XX-alpine)
##########    
ENV CHROME_BIN="/usr/bin/chromium-browser"\
    PUPPETEER_SKIP_CHROMIUM_DOWNLOAD="true"
########## 
## Update and Install packages
##########
RUN set -x \
    && apk update \
    && apk upgrade \
    && echo "127.0.0.1 localhost" >> /etc/hosts \
    && echo "http://dl-cdn.alpinelinux.org/alpine/edge/testing" > /etc/apk/repositories \
    && echo "http://dl-cdn.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories \
    && echo "http://dl-cdn.alpinelinux.org/alpine/edge/main" >> /etc/apk/repositories \
    # add the packages
    ## g++: used to install NodeJS related packages
    ## chromium: used to run Puppeteer
    && apk add --no-cache g++ chromium 

尝试将最后一行从 chromium 更改为 chromium-browser@73 或 chromium@73 但遇到以下错误:

The repository tag for world dependency 'chromium@73' does not exist

仅供引用，当我刚刚安装 chromium 并运行下面的 NodeJS 代码时出现错误:

Line239: await page.pdf({
            path: TEMP_DIR + filename, 
            format: 'A4',
            printBackground: true
         });

printPdf() Error

nodejs 基础镜像中使用的边缘分支中不存在 chromium73。您必须将分支设置为 v3.10 才能下载 chromium73。

alpine chromium&branch=v3.10

FROM node:12-alpine
RUN apk add --no-cache  chromium --repository=http://dl-cdn.alpinelinux.org/alpine/v3.10/main

验证安装

docker run -it --rm myalpine ash -c“apk -e info chromium”
