flytectl demo start#

Starts the Flyte demo cluster.

Synopsis#

Flyte demo is a fully standalone minimal environment for running Flyte. It provides a simplified way of running Flyte demo as a single Docker container locally.

Starts the demo cluster without any source code:

flytectl demo start

Mounts your source code repository inside the demo cluster:

flytectl demo start --source=$HOME/flyteorg/flytesnacks

Specify a Flyte demo compliant image with the registry. This is useful in case you want to use an image from your registry.

flytectl demo start --image docker.io/my-override:latest

Note: If image flag is passed then Flytectl will ignore version and pre flags.

Specify a Flyte demo image pull policy. Possible pull policy values are Always, IfNotPresent, or Never:

flytectl demo start --image docker.io/my-override:latest --imagePullPolicy Always

Runs a specific version of Flyte. Flytectl demo only supports Flyte version available in the Github release, https://github.com/flyteorg/flyte/tags.

flytectl demo start --version=v0.14.0

Note

Flytectl demo is only supported for Flyte versions >= v1.0.0

Runs the latest pre release of Flyte.

flytectl demo start --pre

Start demo cluster passing environment variables. This can be used to pass docker specific env variables or flyte specific env variables. eg : for passing timeout value in secs for the demo container use the following.

flytectl demo start --env FLYTE_TIMEOUT=700

The DURATION can be a positive integer or a floating-point number, followed by an optional unit suffix:: s - seconds (default) m - minutes h - hours d - days When no unit is used, it defaults to seconds. If the duration is set to zero, the associated timeout is disabled.

eg : for passing multiple environment variables

flytectl demo start --env USER=foo --env PASSWORD=bar

Usage

flytectl demo start [flags]
