Image Support Only

The AWS Lambda deploy plugin only supports AWS Lambda deployments that utilize ECR images rather than .zip files.

We recommend that the docker build plugin is used to generate these images.

Below is a simple Dockerfile, handler code, and waypoint.hcl for building, deploying, and releasing using Waypoint.

handler.rb

require 'json'

def handler(event:, context:)
    qs = event.fetch("queryStringParameters", {})

    name = qs.fetch("name", "unknown user")

    STDERR.puts "Handling ALB request for #{name}"

    {
        "statusCode": 200,
        "statusDescription": "200 OK",
        "isBase64Encoded": false,
        "headers": {
            "Content-Type": "text/html"
        },
        "body": "<html><body><h1>Hello there #{name} from Lambda!</h1></body></html>"
    }
end

require 'json'

def handler(event:, context:)
    qs = event.fetch("queryStringParameters", {})

    name = qs.fetch("name", "unknown user")

    STDERR.puts "Handling ALB request for #{name}"

    {
        "statusCode": 200,
        "statusDescription": "200 OK",
        "isBase64Encoded": false,
        "headers": {
            "Content-Type": "text/html"
        },
        "body": "<html><body><h1>Hello there #{name} from Lambda!</h1></body></html>"
    }
end

docker (builder)

Build a Docker image from a Dockerfile.

If a Docker server is available (either locally or via environment variables such as "DOCKER_HOST"), then "docker build" will be used to build an image from a Dockerfile.

Dockerless Builds

Many hosted environments, such as Kubernetes clusters, don't provide access to a Docker server. In these cases, it is desirable to perform what is called a "dockerless" build: building a Docker image without access to a Docker daemon. Waypoint supports dockerless builds.

Waypoint performs Dockerless builds by leveraging Kaniko within on-demand launched runners. This should work in all supported Waypoint installation environments by default and you should not have to specify any additional configuration.

Interface

Output: docker.Image

Examples

build {
  use "docker" {
    buildkit    = false
    disable_entrypoint = false
  }
}

build {
  use "docker" {
    buildkit    = false
    disable_entrypoint = false
  }
}

Required Parameters

This plugin has no required parameters.

aws-ecr-pull (builder)
