# Default Container Registry

> How to store container images

The Default container registry is a [container registry](/component-gallery/container-registries) flavor which comes built-in with ZenML and allows container registry URIs of any format.

### When to use it

You should use the Default container registry if you want to use a **local** container registry or when using a remote container registry that is not covered by other [container registry flavors](/component-gallery/container-registries#container-registry-flavors).

### Local registry URI format

To specify a URI for a local container registry, use the following format:

```
localhost:

# Examples:
localhost:5000
localhost:8000
localhost:9999
```

### How to use it

To use the Default container registry, we need:

* [Docker](https://www.docker.com) installed and running.

* The registry URI. If you're using a local container registry, check out

* the [previous section](/component-gallery/container-registries/default#local-registry-uri-format) on the URI format.

We can then register the container registry and use it in our active stack:

```
zenml container-registry register  \
    --flavor=default \
    --uri=

# Add the container registry to the active stack
zenml stack update -c 
```

For more information and a full list of configurable attributes of the Default container registry, check out the [API Docs](https://apidocs.zenml.io/latest/integration%5Fcode%5Fdocs/integrations-aws/#zenml.integrations.aws.container%5Fregistries.default%5Fcontainer%5Fregistry.DefaultContainerRegistry).
