Upgrade UCP offlineEstimated reading time: 3 minutes
Upgrading Universal Control Plane is the same, whether your hosts have access to the internet or not.
The only difference when installing on an offline host is that instead of pulling the UCP images from Docker Hub, you use a computer that’s connected to the internet to download a single package with all the images. Then you copy this package to the host where you upgrade UCP.
Use a computer with internet access to download the UCP package from the following links.
Download the offline package
You can also use these links to get the UCP package from the command line:
$ wget <ucp-package-url> -O ucp.tar.gz
Now that you have the package in your local machine, you can transfer it to the machines where you want to upgrade UCP.
For each machine that you want to manage with UCP:
Copy the offline package to the machine.
$ scp ucp.tar.gz <user>@<host>
Use ssh to log in to the hosts where you transferred the package.
Load the UCP images.
Once the package is transferred to the hosts, you can use the
docker loadcommand, to load the Docker images from the tar archive:
$ docker load -i ucp.tar.gz
Now that the offline hosts have all the images needed to upgrade UCP, you can upgrade Docker UCP.
