Deploying & Caveats

App Definition File

This is the hard part (kinda, not really). The application definition file (which we will call appdef.json) is a JSON file which specifies the following details about how to run your application:

• Docker images running
• Environment variables
• Links between containers
• Physical -> virtual port mappings
• Data volumes and their physical mount points (hard drives, can share between containers)
• CPU and RAM on the physical EC2 instance

You can create an appdef.json by running clusternator app:new > appdef.json. More information about the parameters can be found at http://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html

Developing Clusternator

yay contributions!

All code is in src/. The CLI entry point is bin/clusternatorCli.js, but includes from lib/ (the compile destination).

bin/clusternatorCli-es5.js is ultimately what gets run as the CLI from bin/clusternator.sh.

There are unit tests, and e2e tests. Unit tests can be done by running npm test, assuming the project has been npm install'd. This is an alias to gulp test-unit

The e2e tests require AWS credentials, and can be run directly from gulp with gulp test-e2e

The gulp test task will run both the unit, and e2e tests.

Code coverage can be found after tests are run, and is located in the (generated) coverage folder. Coverage includes lcov, json, and html.

Compile ES6

npm run build will transform your ES6 source into ES5

gulp transpile will transpile src/**/*.js to lib/**/*.js

gulp watch will look at src/**/*.js, and transpile them to lib/**/*.js

Running the clusternator CLI

Run ./bin/clusternator.sh from the root directory.

Project Init

Requires the Current Working Directory to be a git repository, or a subfolder within a git repository. The command will interactively create a .clusternator file in the project's root directory, and will provision the networking infrastructure for a project on AWS. This currently requires an existing VPC, and Route (AWS bootstrapping coming soon!),
