Users who have configured DTR 1.1.0 to run behind a firewall may experience issues wherein proxy settings are not being respected by DTR containers. In addition, DTR 1.1 may not be able to reach the update servers from behind your firewall, so you won’t see when new versions are available. DTR 1.1 users are encouraged to update to DTR 1.2 manually (which will fix the proxy issues) and then use the update system in the web UI to do any future updates.
Execute this command to manually patch DTR 1.1.x to 1.2.0 and so remediate these issues.
Before you start, ensure that your Docker daemon is configured with correct proxy settings.
sudo bash -c "$(sudo docker run docker/trusted-registry upgrade 1.2.0)"
Note that you could also use this step to manually update DTR 1.1.1 to 1.2.0.
