| Learn how to upgrade your Docker Trusted Registry | docker, dtr, upgrade, install | Upgrade DTR |
The first step in upgrading to a new minor version or patch release of DTR 2.2, is ensuring you're running DTR 2.1. If that's not the case, start by upgrading your installation to version 2.1, and then upgrade to 2.2.
There is no downtime when upgrading a highly-available DTR cluster. If your DTR deployment has a single replica, schedule the upgrade to take place outside business peak hours to ensure the impact on your business is close to none.
Step 1. Upgrade DTR to 2.1
Make sure you're running DTR 2.1. If that's not the case, upgrade your installation to the 2.1 version.
Step 2. Upgrade DTR
To upgrade DTR, login with ssh into a node that's part of the UCP cluster. Then pull the latest version of DTR:
$ docker pull {{ page.docker_image }}
If the node you're upgrading doesn't have access to the internet, you can use a machine with internet connection to pull all the DTR images.
Once you have the latest images on the node, run the upgrade command:
$ docker run -it --rm \
{{ page.docker_image }} upgrade \
--ucp-insecure-tls
By default the upgrade command runs in interactive mode and prompts you for any necessary information. You can also check the reference documentation for other existing flags.
