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: openwhisk
custom:
  globalSchedule: cron(0 * * * *)

functions:
  hello:
      handler: handler.hello
      events:
        - schedule: ${self:custom.globalSchedule}
  world:
      handler: handler.world
      events:
        - schedule: ${self:custom.globalSchedule}

Using sls print will resolve the variables in the schedule blocks.

$ sls print
service: new-service
provider: openwhisk
custom:
  globalSchedule: cron(0 * * * *)

functions:
  hello:
      handler: handler.hello
      events:
        - schedule: cron(0 * * * *) # <-- Resolved
  world:
      handler: handler.world
      events:
        - schedule: cron(0 * * * *) # <-- 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
