Containers uses templates to provision containers.
About this task
A template is a reusable configuration for provisioning a container or a suite of containers. In a template, you can define a multi-tier application that consists of linked services.
A service is defined as one or more containers of the same type or image.
You can create a custom container template based on an existing template on the Templates page or import a properly formatted YAML file. You can also provision a container template or image.
