You can pull images from any registry that has been added to Portainer, or using advanced mode, from a custom external registry.
On a multi-node environment, the pulled image will only be available on the node you select in the Deployment section. To make the image available to all nodes, consider adding a registry to Portainer.
Method 1: Pulling images in simple mode
This method lets you pull images from Docker Hub or from another registry that you have connected with before.
From the menu select Images. Select the registry to use then enter the name of the image. On a multi-node environment, select the node to deploy to.
When you're ready, click Pull the image.
Method 2: Pulling images in advanced mode
Using advanced mode, you can define a custom registry URL, port and image. This is ideal if you run your own private registry but don't want to add it to the registries list in Portainer.
From the menu select Images then select Advanced mode. Next, enter the registry, port and image in the Image box. On a multi-node environment, select the node to deploy to.
