If you have a github repository with Dockerfile, you can use this module to build an ECS that can be accessed from a custom domain.
Mainly works as follows:
- This module arranges CodePipeline using github as a hook and resources provisioned to it.
- The deployment destination of CodePipeline is Fargate in ECS.
- And ECS is linked to Load Balancer, enable access via its own domain.
You can publish the github source by customizing the four values.
- Application Name.
- Vpc and subnets to use.
- Port to Use(Internal and public).
- Github repository to use.
provider "aws" {
region = "ap-northeast-1"
}
locals {
# 1. Your app name.
application_name = "simple-go-ping-api"
application_name_lower = replace(lower(local.application_name), "/[^a-z0-9]/", "")
}
module "ecs-deployline" {
source = "ispec-inc/ecs-deployline/aws"
version = "0.4.3"
# 2. Your vpc and subnets id.
vpc_id = "vpc-0000000"
public_subnets = ["subnet-1112", "subnet-2222"]
cluster_name = local.application_name
app_repository_name = local.application_name
container_name = local.application_name
# 3. Port to use
alb_port = "8005"
container_port = "8005"
helth_check_path = "/ping"
# 4. Your github repository.
git_repository = {
owner = "murawakimitsuhiro"
name = "go-simple-RESTful-api"
branch = "feature/only-ping"
}
}warning
- Dockerfile should be placed at the root of the git repository to be used, and be ready to build.
- In this simple sample, we do not link the domain or use SSL.
