Deploy Project

Jets Account

You will need a Jets account to deploy. You can sign up at www.rubyonjets.com. New users get a 14-day free trial period for their AWS account.

Deploy

Let’s deploy the project to AWS Lambda.

❯ jets deploy

The deploy command shows the stack that will be deploy and ask if you are sure.

❯ jets deploy
Will deploy sinatra-dev
Are you sure? (y/N) y

Type y and press enter to kick off the deploy.

How Jets Deployment Works

  1. Jets first creates a bootstrap stack to create an S3 bucket and CodeBuild project.
  2. It packages up your code to a zip file and uploads it S3 for deployment.
  3. The rest of the deploy runs on the CodeBuild Remote Runner. It analyzes your source code, uses Docker to build dependencies, and deploys with CloudFormation to your AWS account.

Serverless Resources like AWS Lambda Functions, CloudWatch Event Rules, CloudFront Distributions, SQS Job Queues are created based on what you’ve configured. At the end, you see an AWS Lambda Function URL that points to your deployed app.

Tip: For faster deploys, you can use a Remote Docker Daemon or CodeBuild Fleets. This speeds up the build times since Docker caches can be reused.

Release History

A release record is created at the end of the deployment. You can see the release history with:

❯ jets release:history
Releases for stack: sinatra-dev
+---------+-----------------+---------------+---------+
| Version |     Status      |  Released At  | Message |
+---------+-----------------+---------------+---------+
| 1       | UPDATE_COMPLETE | 8 minutes ago | Deploy  |
+---------+-----------------+---------------+---------+

For detailed information about each release you can also use jets release:info. You can also rollback to previous code and infrastructure with jets rollback if needed.

Next, we’ll review the deployed project.
