This is a test.

This project will create a new app from a docker image using a user-provided ECRurl via AWS's ECS service. The app created will be automatically load-balanced and auto-scaled on EC2 instances. All underlying infrastructure, including a vpc, subnets, security groups, ECS clusters, load-balancers, autoscaling group for your EC2 instances, listeners, listener rules and target groups, will be automatically provisioned for you when you deploy.

This project runs on Pulumi, a free open-source CloudFormation platform similar to Terraform, Ansible, and the AWS-CDK. We chose Pulumi because it is cloud agnostic, more intuitive than Terraform and Ansible, and takes fewer lines of code to create complex infrastructure than other platforms.

The first time this project is set up and deployed it should take you 20 minutes or less, depending on comfort working with AWS and scripts. The initial setup only happens once, and from there every new app afterward only uses Step 3 (from below) and then the command make deploy. That means that every new app that needs to be launched will take less than 5 minutes to get deployed.

Before the Getting Started section, make sure you have made a new image and pushed it to AWS ECR. You will need to copy the ECRUrl from the image into the index.ts file. You also need to create a free Pulumi account early on as new accounts can take a few hours to validate.

Below is a quick outline of the steps needed to deploy your first app using this Pulumi template.

Do all 5 steps the first time you set up an app.

Only do Step 3 and the command make deploy.

• Create a certificate for your domain and a new standard-string parameter for the following value: '/aiAPI/certArn'.
• '/aiAPI/certArn' should be a verified AWS Certificate Manager certificate, to enable HTTPS traffic through your load balancer.
• Request a certificate and validate it through EMAIL or DNS. Once it is validated, copy the ARN of the certificate and go to AWS Systems Manager. Create a new standard-string parameter called '/aiAPI/certArn' (spelling and capitalization is important). Paste the arn you copied into the value field and create the parameter.

• Create a new Pulumi stack in the Pulumi dashboard.
• Create a new acecss token and copy it (you will only see it once) into the makefile.
• You also need to update the Pulumi owner field and the stack name field to yourself and the name of the new stack you just created, respectively.

• Go to the index.ts file and update the following fields: domainName, region, instanceType, ebsVolumeSize, and all the parameters under the apps variable.

make prepare

This command will install Pulumi and all the dependencies this app needs to run

make login

This command will log you in to Pulumi using the account name and access token you provided in a previous step.

make deploy

This command will deploy your app and all the necessary AWS resources.

• Create a subdomain (in AWS Route53 if that is what you use) and point it at the load-balancer that was just created. To do this in AWS Route53, go to your Hosted Zones and create a new record set. Check "Yes" for Alias and in the drop down list the name of your load-balancer should appear.
• Lastly, create an autoscaling policy for your ECS tasks. Pulumi does not have functionality to autoscale ECS tasks, so this step must be done manually.

Optional things you can do later with this project: -Parameterizing tokens -Moving to spotinst -Automating with a bitbucket pipeline, circleci, etc. -Multiple environments
