. - Click Add execution environment in the page header.
- Select the registry you wish to pull from. The "name" field displays the name of the image that will show up as on your local registry.
The "Upstream name" field is the name of the image on the remote server. For example if the upstream name is set to "alpine" and the “name” field to "local/alpine", the alpine image will be downloaded from the remote and renamed to local/alpine.
