Serverless Whitelisting

Create a whitelist for IP addresses, CIDR for a serverless application, using serverless resource policies.

This plugin requires serverless 3.18 or higher.

Private and Public Stages

IP addresses, CIDR are whitelisted by stages and publicPaths.

• privateStages: Private to whitelisted CIDR and IP addresses. In the example below, staging and production stages are privateStages, so only those CIDR and IP addresses can access staging and production.
• publicStages: No whitelisting necessary. These stages are public to all CIDR and IP addresses.
• publicPaths: No whitelisting necessary regardless stages.

How to Use

1. Install in your serverless application: npm install --save serverless-whitelisting
2. In your serverless.yml file, add the serverless-whitelisting to plugins, for example:

   plugins:
   - serverless-whitelisting

3. Within the provider block, add a stage variable:

   provider:
     stage: ${opt:stage, 'dev'}

4. Within a custom block, add:

   custom:
     serverless-whitelisting:
       stage: ${self:provider.stage}
       privateStages:
         - staging
         - production
       publicStages:
         - test
       netblocks:
         - 212.204.161.60/24
         - 68.159.185.46
       publicPaths:
         - oauth
         - oauth-test

The netblocks object will contain the list of whitelisted IPs.
