Serverless plugin to enable custom AWS resource names
Install the plugin to your project:
npm install serverless-aws-resource-names --save
Add the plugin and its configuration to your serverless project:
plugins:
- serverless-aws-resource-names
custom:
serverless-aws-resource-names:
source: mapping.json
Create the mapping.json file in your project and modify the names to your hearts desire!
{
"template": {
"compiled": "cloudformation-template-update-stack.json",
"core": "cloudformation-template-create-stack.json"
},
"stack": "$service-$stage",
"role": {
"Fn::Join": [
"-", [
"$service",
"$stage",
"$region",
"lambdaRole"
]
]
},
"policy": {
"Fn::Join": [
"-", [
"$stage",
"$service",
"lambda"
]
]
},
"apiGateway": "$stage-$service",
"lambda": "$service-$stage-$lambda",
"logGroup": "/aws/lambda/$service-$stage-$lambda"
}
- $service - Refers to the service attribute in your serverless.yml
- $stage - Refers to the stage which you deploy to via serverless e.g. sls deploy -s dev
- $region - Refers to the AWS region that you are deploying to. This is configured in your serverless.yml under the provider.region attribute or by your AWS CLI configuration.
- $lambda - Refers to the name of your lambda function, defined in your serverless.yml under the functions attribute.
- $rand - Globally replaces all instances with a random UUID.
You can define custom variables in your serverless.yml file:
plugins:
- serverless-aws-resource-names
custom:
serverless-aws-resource-names:
source: mapping.json
variables:
functionSuffix: func
And then use these custom variables in your mapping.json file:
{
"lambda": "$service-$stage-$lambda-$functionSuffix",
}
Here we've defined a custom variable functionSuffix and assigned it the value 'func'.
This will append the string 'func' to all of your Lambda function names.
