You can specify additional configurations a
lambdaEdgePreExistingCloudFront value in the custom section of your serverless.yml file. A
validStages value allows you to specify valid stage names for deploy Lambda@Edge.
lambdaEdgePreExistingCloudFront: validStages: - staging - production
This plugin will first check for
validStages property defined in the
custom section. If
validStages is used, then all the
preExistingCloudFront events are only possible to be updated at the
validStages. If not used, all the
preExistingCloudFront events are possible to be updated at any stage.
Then at all valid stages, the plugin checks - for each
preExistingCloudFront event - if the provider’s stage is the same as the
stage property defined for each
preExistingCloudFront event. If they match, then that particular
preExistingCloudFront event will be updated.
stage is not used for a
preExistingCloudFront event, then that event will be updated at all
validStages or all stages if
validStages is not used.
