Hapiest-lambda-deploy is designed to make it super-simple to deploy one or more lambda functions in a repository.

Setup

1. Create a deploy config folder with the following files:

   i. deployConfig.json (see example below)

   {
     "lambdaFunctions": [{
       "functionName": "hapiestLambdaDeployTest",
       "zipContents": [
         "index.js",
         "lib"
       ],
       "environments": [
         {
           "envName": "env1",
           "nodeEnvValue": "environment1",
           "liveAliasName": "LIVE"
         }, {
           "envName": "env2",
           "nodeEnvValue": "environment2",
           "liveAliasName": "LIVE"
         }
       ]
     }]
   }

   ii. deployCredentials.json (see example below)

   {
     "awsCredentials": {
       "accessKeyId": "someIAMAccessKeyId",
       "secretAccessKey": "someIAMSecretAccessKey",
       "region": "us-east-1"
     }
   }

2. Create a "bin" .js file similar to the one below

   const Promise = require('bluebird');
   const Path = require('path');
   const NodeConfig = require('config');
   const serviceLocator = require('../../services/serviceLocatorFactory').getServiceLocatorSingleton(NodeConfig);
   const logger = serviceLocator.getLogger();
      
   /** @type {DeployLambdaServiceFactoryFolders} */
   const folders = {
       config: Path.resolve(__dirname, '../config'),
       projectRoot: Path.resolve(__dirname, '../..')
   };
   const DeployServiceFactory = require('hapiest-lambda-deploy');
   const deployService = DeployServiceFactory.create(folders, logger);
      
   deployService.deployFromCommandLineArguments(process.argv)
   .then(() => process.exit())
   .catch(err => logger.error('Deploy failed', err));

3. Update package.json to make it easy to deploy using "npm run ..."

   {
       "scripts": {
           "git:ensureClean": "test -z \"$(git status --porcelain)\" || (echo \"Dirty working directory - aborting\" && test -n \"\")",
           "deploy:env1": "npm run git:ensureClean && node deploy/bin/deploy.js -f hapiestLambdaDeployTest -e env1 -c $(git rev-parse HEAD)"
       }
   }

   Note, you want to ensure that you have a clean directory so that you don't accidentally deploy code that hasn't been tested / check in. You can optionally remove git:ensureClean step if you like playing Russian Roulette.

4. Deploy the Lambda function by running

   npm run deploy:env1

Running the tests

Currently there's only a single integration test. I plan to add unit tests at some later point in time. To get the integration test up and running, you should:

1. Create test/helper/integration/config/deployCredentials.json file with valid credentials from Setup step 1

2. Create an AWS Lambda function with the name hapiestLambdaDeployTest_env1 and a corresponding alias named LIVE

3. Check that the test runs using npm run test:integration
