#Print

Print your serverless.yml config file with all variables resolved.

If you're using Serverless Variables in your serverless.yml, it can be difficult to know if your syntax is correct or if the variables are resolving as you expect.

With this command, it will print the fully-resolved config to your console.

serverless print

#Options

• format Print configuration in given format ("yaml", "json", "text"). Default: yaml
• path Period-separated path to print a sub-value (eg: "provider.name")
• transform Transform-function to apply to the value (currently only "keys" is supported)

#Examples:

Assuming you have the following config file:

service: new-service
provider: google

custom:
  resource: projects/*/topics/my-topic

functions:
  first:
    handler: firstPubSub
    events:
      - event:
          eventType: providers/cloud.pubsub/eventTypes/topics.publish
          resource: ${self:custom.resource}
  second:
    handler: secondPubSub
    events:
      - event:
          eventType: providers/cloud.pubsub/eventTypes/topics.publish
          resource: ${self:custom.resource}

Using sls print will resolve the variables in the resource blocks:

$ sls print
service: new-service
provider: google

custom:
  resource: projects/*/topics/my-topic

functions:
  first:
    handler: firstPubSub
    events:
      - event:
          eventType: providers/cloud.pubsub/eventTypes/topics.publish
          resource: projects/*/topics/my-topic # <-- Resolved.
  second:
    handler: secondPubSub
    events:
      - event:
          eventType: providers/cloud.pubsub/eventTypes/topics.publish
          resource: projects/*/topics/my-topic # <-- Resolved.

This prints the provider name:

sls print --path provider --format text

And this prints all function names:

sls print --path functions --transform keys --format text
