Stacktape


Next.js SSR website

Next.js SSR website

  • This project deploys a simple Server-side rendered NextJS application.
  • The project uses a Container workload to run the Next app.

Pricing

  • Fixed price resources:

    • Container workload (~$0.012/hour, ~$9/month)
  • There are also other resources that might incur costs (with pay-per-use pricing). If your load won't get high, these costs will be close to $0.

Prerequisites

If you're deploying from your local machine (not from a CI/CD pipeline), you need the following prerequisites:

1. Generate your project

The command below will bootstrap the project with pre-built application code and pre-configured stacktape.yml config file.

Copy

stp init --projectId nextjs-ssr-website

2. Deploy your stack

  • To provision all the required infrastructure and to deploy your application to the cloud, all you need is a single command.
  • The deployment will take ~5-15 minutes. Subsequent deploys will be significantly faster.

Copy

stp deploy --stage <<stage>> --region <<region>>

stage is an arbitrary name of your environment (for example staging, production or dev-john)

region is the AWS region, where your stack will be deployed to. All the available regions are listed below.


Region name & Locationcode
Europe (Ireland)eu-west-1
Europe (London)eu-west-2
Europe (Frankfurt)eu-central-1
Europe (Milan)eu-south-1
Europe (Paris)eu-west-3
Europe (Stockholm)eu-north-1
US East (Ohio)us-east-2
US East (N. Virginia)us-east-1
US West (N. California)us-west-1
US West (Oregon)us-west-2
Canada (Central)ca-central-1
Africa (Cape Town)af-south-1
Asia Pacific (Hong Kong)ap-east-1
Asia Pacific (Mumbai)ap-south-1
Asia Pacific (Osaka-Local)ap-northeast-3
Asia Pacific (Seoul)ap-northeast-2
Asia Pacific (Singapore)ap-southeast-1
Asia Pacific (Sydney)ap-southeast-2
Asia Pacific (Tokyo)ap-northeast-1
China (Beijing)cn-north-1
China (Ningxia)cn-northwest-1
Middle East (Bahrain)me-south-1
South America (São Paulo)sa-east-1

3. Test your application

After a successful deployment, some information about the stack will be printed to the console (URLs of the deployed services, links to logs, metrics, etc.).

  • Explore your application at mainApiGateway -> url. The URL was printed to the console.

4. Run the application in development mode

To run a container in the development mode (locally on your machine), you can use the dev command.

Copy

stp dev --region <<your-region>> --stage <<stage>> --resourceName nextJsApp --container next-container

Stacktape runs the container as closely to the deployed version as possible:

  • Maps all of the container ports specified in the events section to the host machine.
  • Injects parameters referenced in the environment variables by $ResourceParam and $Secret directives to the running container.
  • Injects credentials of the assumed role to the container. This means that your locally running container will have the exact same IAM permissions as the deployed version.
  • Pretty-prints logs (stdout/stderr) produced by the container to the terminal.

The container is rebuilt and restarted, when you either:

  • type rs + enter to the terminal
  • use the --watch option and one of your source code files changes

5. Hotswap deploys

  • Stacktape deployments use AWS CloudFormation under the hood. It brings a lot of guarantees and convenience, but can be slow for certain use-cases.

  • To speed up the deployment, you can use the --hotSwap flag that avoids Cloudformation.

  • Hotswap deployments work only for source code changes (for lambda function, containers and batch jobs) and for content uploads to buckets.

  • If the update deployment is not hot-swappable, Stacktape will automatically fall back to using a Cloudformation deployment.

Copy

stacktape deploy --hotSwap --stage <<stage>> --region <<region>>

6. Delete your stack

  • If you no longer want to use your stack, you can delete it.
  • Stacktape will automatically delete every infrastructure resource and deployment artifact associated with your stack.

Copy

stp delete --stage <<stage>> --region <<region>>

Stack description

Stacktape uses a simple stacktape.yml configuration file to describe infrastructure resources, packaging, deployment pipeline and other aspects of your services.

You can deploy your services to multiple environments (stages) - for example production, staging or dev-john. A stack is a running instance of a service. It consists of your application code (if any) and the infrastructure resources required to run it.

The configuration for this service is described below.

1. Service name

You can choose an arbitrary name for your service. The name of the stack will be constructed as {service-name}-{stage}.

Copy

serviceName: nextjs-ssr-website

2. Resources

  • Every resource must have an arbitrary, alphanumeric name (A-z0-9).
  • Stacktape resources consist of multiple (sometimes more than 15) underlying AWS or 3rd party resources.

2.1 HTTP API Gateway

API Gateway receives requests and routes them to the container.

For convenience, it has CORS allowed.

Copy

resources:
mainApiGateway:
type: http-api-gateway
properties:
cors:
enabled: true

2.2 Container workload

Application code runs inside a container workload with a single container. The workload is configured as follows:

  • Container. This container workload uses only a single container: next-container. The container is configured as follows:
    • Packaging - determines how the Docker container image is built. In this example, we are using the Next.js Docker starter. This starter already comes with Dockerfile which we are using. Stacktape builds the Docker image, and pushes it to a pre-created image repository on AWS. You can also use other types of packaging.
    • We are configuring events(requests) that can reach the container. By configuring the path to /{proxy+}, the method to '*' and the containerPort to 3000, the event integration routes all requests (no matter the method or path) coming to the HTTP API Gateway to port 3000 of the container.
  • Resources. Resources are shared between containers of container workload (in this case, we only have one container). The cheapest available resource configuration is 0.25 of virtual CPU and 512 MB of RAM.

You can also configure scaling. New (parallel) container workload instance can be added when (for example) the utilization of your CPU or RAM gets larger than 80%. The HTTP API Gateway will evenly distribute the traffic to all container workloads.
