Updating a Docker container

When you install a user-managed checkpoint a script is created and a scheduled task is setup that will update the checkpoint container every hour. If you need to update outside of this schedule, a manual update can be performed.

How to update manually?

First, make sure that the steps explained in Install a Docker checkpoint have been executed earlier.

  1. Open a PowerShell console in admin mode.
  2. Go to the folder where the docker-compose.yml file lives and execute the following commands.
  3. Type docker-compose pull in the command-line.
  4. Type docker-compose down in the command-line.
  5. Type docker-compose up in the command-line.

During the update, your other private checkpoints will take over doing checks. The soon to be updated checkpoint does not need to be disabled for a successful update. As you should have at least one other checkpoint instance (again this is strongly recommended) you can update without having to make any other changes like disabling checkpoints, stopping monitors, etc.

It is important to keep your Docker containers up to date. The containers have a built-in Chrome and Edge browser that must be kept up to date to not become a security liability. Uptrends will show a warning or error if we consider your containers to be out of date.
