說明：運行一個openjdk的基礎容器（在空白基礎鏡像內安裝后，指定程序，如springboot程序打包成docker鏡像并運行使用哈），并進入docker容器內部，操作安裝，建議看完全文再操作哈，坑是一點點踩的。
啟動openjdk容器命令如下：

docker run --name openjdk8 -itd openjdk:8

0、需要將apt-get升級：apt-get update

4、安裝好依賴后，重新安裝 wkhtmltox_0.12.6-1.buster_amd64.deb

root@c0802ee02685:/data# dpkg -i wkhtmltox_0.12.6-1.buster_amd64.deb (Reading database ... 13929 files and directories currently installed.) Preparing to unpack wkhtmltox_0.12.6-1.buster_amd64.deb ... Unpacking wkhtmltox (1:0.12.6-1.buster) over (1:0.12.6-1.buster) ... Setting up wkhtmltox (1:0.12.6-1.buster) ...

安裝后，發現/usr/local/bin 目錄下已經有了所需工具

root@c0802ee02685:/data# cd /usr/local/bin/ root@c0802ee02685:/usr/local/bin# ls docker-java-home wkhtmltoimage wkhtmltopdf

經過測試ok。

打包dokcer鏡像

注意：（本機用的話，去掉reg.wangdy.com:8443/k8snb/）

# 打包 docker commit -a "wangdy" c0802ee02685 reg.wangdy.com:8443/k8snb/openjdk:wangdy8wkhtml2pdfnew # 推送到私有harbor倉庫 docker push reg.wangdy.com:8443/k8snb/openjdk:wangdy8wkhtml2pdfnew

5、一些用到的其他命令：

docker 將文件從 本機 傳輸到 docker容器內

# 把當前路徑下的simsun.ttc文件傳輸到容器（id）7d36669b3e44 的/data/html2pdf目錄下 docker cp simsun.ttc 7d36669b3e44:/data/html2pdf/

docker 將文件從 docker容器內 傳輸 到本機

# 將容器（id）7d36669b3e44的/data/html2pdf/S2.pdf的文件傳輸到當前目錄 docker cp 7d36669b3e44:/data/html2pdf/S2.pdf .

6、Debian系統中安裝字體（解決中文亂碼）

依次執行以下命令：
mkdir /usr/share/fonts/myfont
mv simsun.ttc /usr/share/fonts/myfont
chmod 644 /usr/share/fonts/myfont/*
cd /usr/share/fonts/myfont
mkfontdir
fc-cache -fv
全過程如下：

root@c0802ee02685:/data# mkdir /usr/share/fonts/myfont root@c0802ee02685:/data# mv simsun.ttc /usr/share/fonts/myfont root@c0802ee02685:/data# chmod 644 /usr/share/fonts/myfont/* root@c0802ee02685:/data# cd /usr/share/fonts/myfont root@c0802ee02685:/usr/share/fonts/myfont# ls simsun.ttc root@c0802ee02685:/usr/share/fonts/myfont# mkfontdir root@c0802ee02685:/usr/share/fonts/myfont# fc-cache -fv /usr/share/fonts: caching, new cache contents: 0 fonts, 3 dirs /usr/share/fonts/X11: caching, new cache contents: 0 fonts, 4 dirs /usr/share/fonts/X11/75dpi: caching, new cache contents: 358 fonts, 0 dirs /usr/share/fonts/X11/encodings: caching, new cache contents: 0 fonts, 1 dirs /usr/share/fonts/X11/encodings/large: caching, new cache contents: 0 fonts, 0 dirs /usr/share/fonts/X11/misc: caching, new cache contents: 89 fonts, 0 dirs /usr/share/fonts/X11/util: caching, new cache contents: 0 fonts, 0 dirs /usr/share/fonts/myfont: caching, new cache contents: 2 fonts, 0 dirs /usr/share/fonts/truetype: caching, new cache contents: 0 fonts, 1 dirs /usr/share/fonts/truetype/dejavu: caching, new cache contents: 6 fonts, 0 dirs /usr/local/share/fonts: caching, new cache contents: 0 fonts, 0 dirs /root/.local/share/fonts: skipping, no such directory /root/.fonts: skipping, no such directory /usr/share/fonts/X11: skipping, looped directory detected /usr/share/fonts/myfont: skipping, looped directory detected /usr/share/fonts/truetype: skipping, looped directory detected /usr/share/fonts/X11/75dpi: skipping, looped directory detected /usr/share/fonts/X11/encodings: skipping, looped directory detected /usr/share/fonts/X11/misc: skipping, looped directory detected /usr/share/fonts/X11/util: skipping, looped directory detected /usr/share/fonts/truetype/dejavu: skipping, looped directory detected /usr/share/fonts/X11/encodings/large: skipping, looped directory detected /var/cache/fontconfig: cleaning cache directory /root/.cache/fontconfig: not cleaning non-existent cache directory /root/.fontconfig: not cleaning non-existent cache directory fc-cache: succeeded

然后就可以基于該鏡像，打包程序了
如下Dockerfile（注意：本機用的話，去掉reg.wangdy.com:8443/k8snb/）

FROM reg.wangdy.com:8443/k8snb/openjdk:wangdy8wkhtml2pdfnew ARG app ADD <APP> app.jar RUN ["/bin/bash", "-c", "chmod 777 app.jar "] CMD java -Xms512M -Xmx2048M -jar /app.jar --server.port=8080

建議： 將容器內用過的安裝包，測試文件等無用文件刪除，減少鏡像大小。
