Step 1: Install Docker on Ubuntu
For simplicity, this tutorial installs Docker from the default Ubuntu software repository.
sudo apt update
sudo apt install docker.io
Once installed, the Docker daemon should be automatically started. You can check its status with:
systemctl status docker
Hint: If the above command doesn’t quit immediately, you can press the Q key to make it quit.
If it’s not running, then start the daemon with this command:
sudo systemctl start docker
And enable autostart at boot time:
sudo systemctl enable docker
Step 2: Install and Run Collabora Online Server with Docker
Execute the following command to pull the latest Collabora Online Development Edition image from Docker hub.
sudo docker pull collabora/code
Then start a new container, for example:
sudo docker run -t -d -p 0.0.0.0:9980:9980 -e "domain=example\\.com" -e "username=admin" -e "password=123456" --restart always --cap-add MKNOD collabora/code
Replace example\.com with your server/ZenTao hostname, preseving the double slashes. This is because Collabora only allows known hosts to access its service and we need to add the server/ZenTao hostname to the whitelist with the domain= parameter.
-d: Detached mode makes the container run in the background.
-t: Allocate a pseudo-TTY
-p: Publish a container’s port to the host.
-e: Set environment variables
The Collabora Online server will be listening on port 9980 of localhost (127.0.0.1) as can be shown by issuing the following command. (If your Ubuntu system doesn’t have the netstat command, you can install it with sudo apt install net-tools.)
sudo netstat -lnpt | grep docker
Since I am using
sudo docker run -t -d -p 0.0.0.0:9985:9980 -e 'domain=192\\.168\\.2\\.111' -e "username=admin" -e "password=123456" --restart always --cap-add MKNOD collabora/code
So I get this result
Go to browser and visit https://your domian:9985 (Since SSL is enabled by default, so you have to visit by HTTPS if you haven't edited configuration file of Collabora Online ), you will get a "OK" page.
Since my ZenTao is not running with SSL, so I need to configure loolwsd.xml to disable SSL. ( If ZenTao is running with SSL, then Collabora has to run with SSL as well, it's the same if ZenTao disables SSL. Otherwise Collabora Online will not be enabled successfully in ZenTao )
Step 3: Use the configuration file directly to set Collabora Online
After starting the container, you can copy the configuration file out of the container, edit it, and copy it back to the container. The container will notice that the configuration file has changed, and the service will be restarted (don’t forget the –restart always option when you start the container with docker run).
- Find out the name or hash of your container:
$sudo docker ps
The output would be something like this:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e4212ca0e6d6 collabora/code "/bin/sh -c 'bash st…" 25 minutes ago Up 25 minutes 0.0.0.0:9985->9980/tcp admiring_sinoussi
- Copy out the config file:
$sudo docker cp admiring_sinoussi:/etc/loolwsd/loolwsd.xml loolwsd.xml
For disable SSL, make sure you have editted value for SSL settings as "false"
<ssl desc="SSL settings">
<as_scheme type="bool" default="true" desc="When set we exclusively use the WOPI URI's scheme to enable SSL for storage">false</as_scheme>
<enable type="bool" desc="If as_scheme is false or not set, this can be set to force SSL encryption between storage and loolwsd. When empty this defaults to following the ssl.enable setting"></enable>
<ssl desc="SSL settings">
<enable type="bool" desc="Controls whether SSL encryption between browser and loolwsd is enabled (do not disable for production deployment). If default is false, must first be compiled with SSL support to enable." default="true">false</enable>
- Edit the config file with your favourite editor, then save and copy it back to the container:
$sudo docker cp loolwsd.xml admiring_sinoussi:/etc/loolwsd/loolwsd.xml
Wait a few seconds for the automatic restart.
You might meet the problem that the container could not restart successfully and logs is as the following,

Try with the following commands to fix the problem by chown beacause of "Permission denied"
sudo docker stop admiring_sinoussi
sudo docker start admiring_sinoussi
sudo docker exec -it -u root admiring_sinoussichown lool:lool /etc/loolwsd/loolwsd.xml
And then visit http://192.168.2.111:9985, you will get a "OK" page if you succeed.
Step 4: Set up in ZenTao
Go to Admin - Integration - Office to enable LibreOffice and Check "Collabora Online", for Collabora Path, just fill in with exact address and port number for your Collabora Online.
Go to Doc in ZenTao and create a Word file to see if it's working.
