# Docker registry

A docker registry is a repository of docker images that implement your custom implementation of pluggable modules like a featurizer, attribute(metadata) generator etc enabling you to build your own pipelines. Please refer to [Pipelines and Dockers](/data-explorer/docs/pipelines-and-dockers) for more details.

## Register a docker registry

1. The prerequisites for registration of a docker registry are
  1. A docker registry URL pointing to a docker registry in DockerHub or AWS ECR (Elastic Container Registry).
  2. If the docker registry needs credentials to pull images, then a Secret must be registered on the [Secrets](/data-explorer/docs/secrets) page. The type of secret needed for DockerHub hosted repo is 'Basic Auth', and that for AWS ECR is 'AWS'.
2. Navigate to the docker registry page under **Data > Processing Options > Docker Registries** on the left navigation panel.
