IaSQL on SQL

In this tutorial, we will run SQL queries on an IaSQL database to deploy a Node.js HTTP server within a docker container on your AWS account using Fargate ECS, IAM, ECR, and ELB. The container image will be hosted as a private repository in ECR and deployed to ECS using Fargate.

Start managing an AWS account with a hosted IaSQL db

First, make sure you have an IAM user in AWS or create one with Programmatic access through the console/UI or CLI. Ensure that the IAM role has sufficient permissions to deploy and manage all your infrastructure resources.

There are two parts to each access key, which you’ll see in the IAM console/CLI after you create it, an id and a secret. Input these in the connect account modal:

If you use the AWS CLI, you can look at the credentials configured locally. In macOS and Linux this is as simple as:

$ cat ~/.aws/credentials
[default]
aws_access_key_id = <YOUR_ACCESS_KEY_ID>
aws_secret_access_key = <YOUR_SECRET_ACCESS_KEY>

You will be able to see your PostgreSQL connection information when you press Connect.

If you want to connect to the PostgreSQL database outside of the IaSQL dashboard SQL editor, make sure to copy the PostgreSQL connection string as you will not see it again.

Add the necessary cloud services to the hosted database

Use the iasql_install SQL function to install modules into the hosted database.

SELECT * from iasql_install(
'aws_ecs_simplified'
);

If the function call is successful, it will return a virtual table with a record for each new table in your database under created_table_name and the number of existing resources or records imported from the account under record_count.

       module_name        |      created_table_name       | record_count
--------------------------+-------------------------------+--------------
aws_cloudwatch | log_group | 0
aws_iam | role | 0
aws_ecr | public_repository | 0
aws_ecr | repository | 1
aws_ecr | repository_policy | 0
aws_security_group | security_group | 2
aws_security_group | security_group_rule | 0
aws_vpc | vpc | 1
aws_vpc | subnet | 3
aws_elb | load_balancer | 0
aws_elb | target_group | 0
aws_elb | listener | 0
aws_elb | load_balancer_security_groups | 0
aws_ecs_fargate | cluster | 0
aws_ecs_fargate | service | 0
aws_ecs_fargate | task_definition | 0
aws_ecs_fargate | container_definition | 0
aws_ecs_fargate | service_security_groups | 0
aws_ecs_simplified | ecs_simplified | 0
(17 rows)

Provision cloud resources in your AWS account

Insert a row into the ecs_simplified table and apply the changes described in the hosted db to your cloud account which will take a few minutes waiting for AWS

INSERT INTO ecs_simplified (app_name, app_port, public_ip, image_tag)
VALUES ('quickstart', 8088, true, 'latest');

SELECT * from iasql_apply();

If the function call is successful, it will return a virtual table with a record for each cloud resource that has been created, deleted, or updated. Login, build and push your code to the container registry

  1. Grab your new ECR URI from the hosted DB
SELECT repository_uri
FROM ecs_simplified
WHERE app_name = 'quickstart';
  1. Login to AWS ECR using the AWS CLI. Run the following command and use the correct <ECR-URI> and AWS <profile>
aws ecr get-login-password --region ${AWS_REGION} --profile <profile> | docker login --username AWS --password-stdin ${QUICKSTART_ECR_URI}
caution

Make sure the CLI is configured with the same credentials, via environment variables or ~/.aws/credentials, as the ones provided to IaSQL, or this will fail.

  1. Build your image locally
docker build -t quickstart-repository app
  1. Tag your image
docker tag quickstart-repository:latest ${QUICKSTART_ECR_URI}:latest
  1. Push your image
docker push ${QUICKSTART_ECR_URI}:latest
  1. Grab your load balancer DNS and access your service!
SELECT load_balancer_dns
FROM ecs_simplified
WHERE app_name = 'quickstart';
  1. Connect to your service!
curl ${QUICKSTART_LB_DNS}:8088/health

Delete managed cloud resources

danger

If you did not create a new account this section will delete all records managed by IaSQL, including the ones that previously existed in the account under any of the used modules. Run SELECT * FROM iasql_plan_apply() after SELECT delete_all_records(); and before SELECT iasql_apply(); to get a preview of what would get deleted. To undo SELECT delete_all_records();, simply run SELECT iasql_sync(); which will synchronize the database with the cloud's state.

  1. Delete all the docker images in the repository
aws ecr batch-delete-image \
--region ${AWS_REGION} \
--repository-name quickstart-repository \
--profile <profile> \
--image-ids imageTag=latest
caution

Make sure the CLI is configured with the same credentials, via environment variables or ~/.aws/credentials, as the ones provided to IaSQL, or this will fail.

  1. Delete all IaSQL records invoking the void delete_all_records function and apply the changes described in the hosted db to your cloud account
SELECT delete_all_records();
SELECT * from iasql_apply();

If the function call is successful, it will return a virtual table with a record for each cloud resource that has been created, deleted or updated.
