    The vpc discovery plugin takes the given vpc name, subnet tag key/value, and security group tag key/value or names in the serverless file to setup the vpc configuration for the lambda.

    Basically we use this config:

    vpcDiscovery:
        vpcName: '<vpc_name>'
        subnets:
          - tagKey: <tag_name>
            tagValues:
              - '<tag_vale>'
        securityGroups:
          - tagKey: <tag_name>
            tagValues:
              - '<tag_value>'
    

    To generate this config:

    vpc:
        subnetIds:
            - subnet-123456789
            ...
        securityGroupIds:
            - sg-123456789
            ...
    

    For each lambda function.

    Note: The core serverless provider.vpc settings will be used, if they are set, instead of vpcDiscovery. You can use also mix settings. For example you may set provider.vpc.subnetIds while using vpcDiscovery to set the securityGroupIds. Take a look at official documentation.

    Getting Started

    Prerequisites

    Make sure you have the following installed before starting:

    Also allow the lambda to have the following IAM permissions:

    • ec2:CreateNetworkInterface
    • ec2:DescribeNetworkInterfaces
    • ec2:DeleteNetworkInterface

    Installation

    Run:

    # From npm (recommended)
    npm install serverless-vpc-discovery
    
    # From github
    npm install https://github.com/amplify-education/serverless-vpc-discovery.git
    

    Then make the following edits to your serverless.yaml file:

    plugins:
      - serverless-vpc-discovery
    
    # Optional: Either set `custom.vpcDiscovery` or `functions.<function name>.vpcDiscovery`
    custom:
      vpcDiscovery:
        vpcName: '<vpc_name>'
        
        # optional if `securityGroups` option is specified
        # list of tag key and values 
        subnets:
          - tagKey: <tag_name>
            
            # an array of values
            tagValues:
              - '<tag_value>'
    
        # optional if `subnets` option is specified
        # list of tag key and value or names
        securityGroups:
          - tagKey: <tag_name>
            
            # an array of values
            tagValues:
              - '<tag_value>'
          
          # optional if `tagKey` and `tagValues` are specified
          # an array of values
          - names:
            - '<security_group_name>'
    
    # Optional: Either set `custom.vpcDiscovery` or `functions.<function name>.vpcDiscovery`
    functions:
      example:
        handler: handler.example
        # inherit `custom.vpcDiscovery` config in case `custom.vpcDiscovery` is specified
      
      example2:
        handler: handler.example
        
        # skip vpc configuration for the current function
        vpcDiscovery: false
        
      example3:
        handler: handler.example
        
        # inherit `custom.vpcDiscovery` config in case `custom.vpcDiscovery` is specified and override security group names
        vpcDiscovery:
          vpcName: '<vpc_name>'
          securityGroups:
            - tagKey: <tag_name>
              
              # an array of values
              tagValues:
                - '<tag_value>'
      
      example4:
        handler: handler.example
        # override or set basic subnets and security groups items
        vpcDiscovery:
          vpcName: '<vpc_name>'
          
          # optional if `custom.vpcDiscovery.securityGroups` option is specified
          subnets: 
            - tagKey: <tag_name>
              
              # an array of values
              tagValues:
                - '<tag_value>'
    
          # optional if `custom.vpcDiscovery.subnets` option is specified
          securityGroups: 
            
            # optional if `names` option is specified
            - tagKey: <tag_name>
              
              # an array of values
              tagValues:
                - '<tag_value>'
            
            # optional if `tagKey` and `tagValues` are specified
            # an array of values
            - names: 
              - '<security_group_name>'

    Running Tests

    To run the test:

    npm test
    

    All tests should pass.

    If there is an error update the node_module inside the serverless-vpc-discovery folder:

    npm install
    

    To run integration tests, set an environment variable TEST_VPC_NAME to the VPC you will be testing for. Then,

    export AWS_PROFILE=your_profile
    export TEST_VPC_NAME=vpc_name
    npm run integration-test
    

    Deploying with the plugin

    When deploying run:

    serverless deploy --env 'VPC Name'
    

    And that should be it! Good Luck!

    How it Works

    The vpc, subnets, and security groups are found by filtering based on a specified tag name. Vpc and subnets are found under the tag name tag:Name. Security groups are found by the name of the group under group-name.

    The vpc is found first as it is used to find the subnets and security groups. Once all of the subnets and security groups are found the serverless service provider creates a vpc object and stores the subnets and security groups.
