The Default container registry is a container registry 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.

​
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 installed and running.
  • The registry URI. If you’re using a local container registry, check out
  • the previous section 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
