Upgrade UCP offlineEstimated reading time: 2 minutes
Upgrading Universal Control Plane is the same, whether your hosts have access to the internet or not.
The only difference when upgrading on an offline host, is that instead of pulling the UCP images from Docker Store, you use a computer that is connected to the internet to download a single package with all the images. Then you copy that package to the host where you’ll upgrade UCP.
Download the offline package
Use a computer with internet access to download a single package with all UCP components:
$ wget <package-url> -O docker-datacenter.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 that machine.
$ scp docker-datacenter.tar.gz <user>@<host>:/tmp
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 < docker-datacenter.tar.gz
Now that the offline hosts have all the images needed to upgrade UCP, you can upgrade Docker UCP.
