Updating your server

Modified on: Tue, 16 Jun, 2020 at 12:59 PM

When there is an update out for the server you will need to follow the instructions below to install the update. There are two sets of instructions below depending on whether you deployed the server with Docker or the Virtual Machine.


Update Docker Images

We recommend that our customers always download the latest docker-compose files directly from our website, to ensure they are using the correct configuration to run our server. You can download the latest versions of the compose files here:


Replace your old docker-compose file with the updated file downloaded. Then run the commands below in the folder containing the compose file.


To download latest image you need to first log into our registry using this command:


Note: The instructions below should be executed from the host server through a terminal (SSH) window. Commands have to be executed with elevated user privileges (e.g. “sudo” or with the “root” user).


docker login registry.paterva.com       #credentials in delivery email


Note: Password will be hidden when logging in. Use sudo if required for docker commands.


You can pull the updated server images by running the "pull" command:


docker-compose -f ctas.yml pull        #Pull latest CTAS image from registry.paterva.com


You can then restart the server by running the "up" command to restart the server using the new images.


docker-compose -f ctas.yml up         #to run CTAS server in foreground 


To run the server in the background, use the following command:


docker-compose -f ctas.yml up -d       #to run CTAS server in background 


Download a new VM

If you cannot pull new docker images due to network restrictions, you can download a new VM containing the updated docker images.


The download link given in your delivery PDF will always point to the latest server image, and can be used again to download the updated VM.


Verify Update

Once you have successfully updated your sever, you can verify the update by browsing to the home page of the server. You will find the new version number in the top left corner as shown in the image below:
