几个前的一篇文章中介绍了phantomjs+echarts生成图表图片的一种方式，但其部署复杂，制作为docker镜像运行就方便多了。文章参见：https://blog.csdn.net/u011943534/article/details/121524397

1、准备echarts

将上次文章中提到过下载的EchartsConvert 解压，并复制到一个安装docker的服务器。
下载地址：https://gitee.com/saintlee/echartsconvert

2、准备phantomjs

将上次文章中个体到过下载的phantomjs解压，并复制bin目录下的phantomjs文件到上一步和echarts相同的目录

下载地址：https://bitbucket.org/ariya/phantomjs/downloads/
注意下载linux版本的

3、编写dockerfile

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
RUN chmod +x /usr/local/bin/phantomjs
ADD echartsconvert-master /echartsconvert-master
RUN apt-get install -y ttf-wqy-zenhei
RUN apt-get install -y xfonts-intl-chinese wqy*
RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtimeEXPOSE 7777
CMD ["/usr/local/bin/phantomjs", "/echartsconvert-master/echarts-convert.js", "-s", "-p", "7777"]

其中sources.list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

4、构建镜像

docker build -t phantomjs:0.0.1 .

5、运行镜像

docker run -d --name=phantomjs --restart=always -p 7777:7777 phantomjs:0.0.1
