Local Image Builder

How to build container images locally
The local image builder is an image builder flavor which comes built-in with ZenML and uses the local Docker installation on your client machine to build container images.
ZenML uses the official Docker Python library to build and push your images. This library loads its authentication credentials to push images from the default config location: $HOME/.docker/config.json. If your Docker configuration is stored in a different directory, you can use the environment variable DOCKER_CONFIG to override this behavior:
export DOCKER_CONFIG=/path/to/config_dir
The directory that you specify here must contain your Docker configuration in a file called config.json.

When to use it

You should use the local image builder if:
  • you're able to install and use Docker on your client machine.
  • you want to use remote components that require containerization without the additional hassle of configuring infrastructure for an additional component.

How to deploy it

The local image builder comes with ZenML and works without any additional setup.

How to use it

To use the Local image builder, we need:
  • Docker installed and running.
  • The Docker client authenticated to push to the container registry that you intend to use in the same stack.
We can then register the image builder and use it to create a new stack:
zenml image-builder register <NAME> --flavor=local
# Register and activate a stack with the new image builder
zenml stack register <STACK_NAME> -i <NAME> ... --set
