Openoffice 4 headless daemon

Image running the OpenOffice 4 soffice daemon service, and solve the problem of Chinese code scrambling.(包括中文乱码问题)

This image was created following the https://github.com/rafaeltuelho/openoffice3-daemon. And thanks he

Build this image:

 docker build --pull -t xiaojun207/openoffice4-daemon --build-arg OO_VERSION=4.1.7 .

Run the container

docker run -d -u 123456 --name soffice -p 8100:8100 -v /data/:/data/ xiaojun207/openoffice4-daemon:latest

When you run this image the container will start the Openoffice daemon in headless mode listening on TCP port 8100 by default. To change this port pass the env var SOFFICE_DAEMON_PORT

If you use java, you can use jodconverter connect the container, like this:

import java.io.File;
import java.io.FileNotFoundException;

import lombok.extern.slf4j.Slf4j;
import org.artofsolving.jodconverter.OfficeDocumentConverter;
import org.artofsolving.jodconverter.office.DefaultOfficeManagerConfiguration;
import org.artofsolving.jodconverter.office.OfficeManager;

...

	public static void main(String[] args){
    DefaultOfficeManagerConfiguration configuration = new DefaultOfficeManagerConfiguration();
    configuration.setOfficeHome("/opt/openoffice4");
    configuration.setPortNumbers(8100);
    configuration.setTaskExecutionTimeout(1000 * 60 * 5L);// 设置任务执行超时为5分钟
    configuration.setTaskQueueTimeout(1000 * 60 * 60 * 24L);// 设置任务队列超时为24小时
    OfficeManager officeManager = configuration.buildOfficeManager();
    String inputFile = "/data/a.docx";
    String pdfFile = "/data/a.pdf"; // 注意输出目录的docker写入权限，否则可能会失败
    System.out.println("进行文档转换转换:" + inputFile + " --> " + pdfFile + ",isRunning:" + officeManager.isRunning());
    OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);
    converter.convert(new File(inputFile), new File(pdfFile));
	}

• Note the write permission of the output directory, otherwise it may fail.

Verify the daemon port is listening for connections

docker exec -it soffice test

Test soffice daemon using unoconv

The unoconv utility is available in this image! You can test a PDF conversion as follow:

• first put some .odt or .doc files into a dir (eg: ~/pdfs) in your host.
• then run the container attaching that dir as a Docker Volume and specifying the file you want to convert"

docker run \
 -v ~/pdfs:/pdfs:rw \
 xiaojun207/openoffice4-daemon \
 unoconv --connection 'socket,host=127.0.0.1,port=8100,tcpNoDelay=1;urp;StarOffice.ComponentContext' \
 -f pdf /pdfs/somefile.doc

• now you should see the file converted to .pdf inside the dir mounted as Volume

Add this container as sidecar for any app depends on Openoffice for any reason (eg. PDF generation).

• import the image and create an Openshift ImageStream

oc import-image openoffice4-daemon --from=docker.io/xiaojun207/openoffice4-daemon --confirm --scheduled

• edit your DeploymentConfig to include the soffice container inside your App POD
