如何构建phantomjs的docker镜像

phantomjs是一个无界面的浏览器，可用于在后端去生成PDF文件。

以下是笔者经过实践可用的镜像脚本Dockerfile，包含phantomjs和nodejs环境

镜像源

当前目录创建sources.list文件,用于替换debian的镜像源为国内镜像，内容如下

deb https://mirrors.tencent.com/debian/ bullseye main non-free contrib
deb-src https://mirrors.tencent.com/debian/ bullseye main non-free contrib
deb https://mirrors.tencent.com/debian-security/ bullseye-security main
deb-src https://mirrors.tencent.com/debian-security/ bullseye-security main
deb https://mirrors.tencent.com/debian/ bullseye-updates main non-free contrib
deb-src https://mirrors.tencent.com/debian/ bullseye-updates main non-free contrib
deb https://mirrors.tencent.com/debian/ bullseye-backports main non-free contrib
deb-src https://mirrors.tencent.com/debian/ bullseye-backports main non-free contrib

Nodejs 

   去官方下载node v16.17.0 linux x64版本压缩包，文件名应该类似：

   node-v16.17.0-linux-x64.tar.xz，放到当前目录。

Phantomjs 

   去phantomjs官网下载安装包，下载地址：phantomjs-2.1.1-linux-x86_64.tar.bz2 

下载后解压后，将bin目录下的phantomjs文件拷到当前目录

Dockerfile

当前目录新建Dockerfile文件，内容如下

FROM debian:stable-slim
RUN apt-get update
RUN apt-get install -y apt-transport-https ca-certificates
 
#mirror
COPY sources.list /etc/apt/sources.list
 
#phantomjs
RUN apt-get update
RUN apt-get install -y libfontconfig1
ENV OPENSSL_CONF /etc/ssl/
COPY phantomjs /usr/local/bin
 
#nodejs
workdir /usr/local/lib/nodejs
COPY node-v16.17.0-linux-x64.tar.xz ./
RUN apt-get install -y xz-utils
RUN tar -xJvf node-v16.17.0-linux-x64.tar.xz -C /usr/local/lib/nodejs
ENV PATH /usr/local/lib/nodejs/node-v16.17.0-linux-x64/bin:$PATH
RUN rm -f node-v16.17.0-linux-x64.tar.xz

构建 

当前目录下应有如下几个文件

运行命令构建： docker build -t phantomjs:test .

 测试

 docker run -it --rm phantomjs:test sh

 #phantomjs

 如果出现如下提示即说明phantomjs安装成功可用

   #node

 如果出现如下提示说明nodejs安装成功
