Openoffice 3 headless daemon

Image running the OpenOffice 3 soffice daemon service

This image was created following the General Container Image Guidelines for Openshift. See the example here https://github.com/RHsyseng/container-rhel-examples/tree/master/starter-arbitrary-uid

Build this image:

 docker build --pull -t rafaeltuelho/openoffice3-daemon --build-arg OO_VERSION=3.2.0 .

Run the container

docker run -it -u 123456 --name=soffice -p 8100:8100 rafaeltuelho/openoffice3-daemon

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

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 \
 rafaeltuelho/openoffice3-daemon \
 unoconv --connection 'socket,host=127.0.0.1,port=8100,tcpNoDelay=1;urp;StarOffice.ComponentContext' \
 -f pdf /pdfs/somefile.odt"

• 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 openoffice3-daemon --from=docker.io/rafaeltuelho/openoffice3-daemon --confirm --scheduled

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