wandb server start

Start a local W&B Server instance in a Docker container.

Pull and run the wandb/local Docker image. Map the specified host port to port 8080 in the container and mount a persistent Docker volume named “wandb” to store data.

Configure the “base_url” setting to point to the local server so that subsequent W&B client calls use it. Prompt for login if no API key is found.

Requires Docker to be installed and running on the host machine.

This command starts only the W&B Models UI. It is provided only for local testing. In production, the W&B Kubernetes Operator is the recommended way to deploy W&B Server. See https://docs.wandb.ai/platform/hosting/self-managed/operator.

For example, to start a local W&B server on the default port (8080):

$ wandb server start

To start the server on port 9090:

$ wandb server start -p 9090

To start the server in the foreground:

$ wandb server start --no-daemon
