Update Feature Flag

How to update a feature flag.

Description

Update an existing feature flag within the specified namespace (or the "default" namespace if unspecified). A feature flag is a group of one or more feature subgraphs. Each feature subgraph represents a replacement of a specific base subgraph that composes a federated graph.

Minimum Requirements

Package	Minimum version
wgc	0.58.0
router	0.95.0

Usage

wgc feature-flag update my-flag --feature-subgraphs fs1 fs2

The alias for feature-flag is ff.

Note that unless specified by the --namespace parameter, the namespace will be automatically passed as "default".

If either the base composition (the federated graph with the original subgraphs) or the feature flag composition fail, the router execution configuration will not be updated with the feature flag configuration.

Parameters

• <name>: The name of the existing feature flag to update. Returns an error if the feature flag does not exist in the specified (otherwise "default") namespace.

Options

• --fs, --feature-subgraphs: A list of names of the feature subgraphs that compose the feature flag. At least one feature subgraph name must be included, and multiple names are space delimited. Including a non-feature subgraph or a feature subgraph that does not exist in the specified (otherwise "default") namespace will produce an error. Including this option will overwrite the existing list.

• -n, --namespace : The namespace of the feature flag (defaults to "default"). Returns an error if the feature flag does not exist in that namespace.

• --label [labels...]:The labels to apply to the feature flag. The labels are passed in the format key=value, and multiple values are space delimited. Including this option will overwrite the existing list.

• --unsetlabels: Removes all existing labels. If the --label parameter is also provided, it will be ignored.

• -j, --json : Output the information in JSON format.

Example

Update the existing feature flag "my-flag" in the namespace "prod" with multiple feature subgraphs and the labels team=A and team=B:

wgc feature-flag update my-flag \
    --feature-subgraphs my-graph my-other-graph \
    -n prod
    --label team=A team=B
