This repository contains the source code for the this tutorial: Creating a notification system with Scaleway SNS and Instances.
To complete the actions presented below, you must have:
- A Scaleway account logged into the console
- Set up authentication for the Terraform provider
- An SSH key
- Set up the Scaleway CLI
This example shows you how to set up a Notification System with Terraform across Instances using Scaleway's products, through a simulated CPU monitoring example.
Once you have cloned this repository, export your public SSH key to a TF_VAR_public_ssh_key environement variable:
export TF_VAR_public_ssh_key=$(cat ~/.ssh/id_ed25519.pub)
Then you can run these commands:
cd terraform
terraform init
terraform plan
terraform apply- Connect to the subscriber Instance with this URL
http://<your_subscriber_ip_address>:8081(you can find the address on the Console Instances page) - Click on
Confirm subscription. If you get an error because the URL hasn't been received, you can reload the page, it should take less than 30s to appear. You will see a AWS xml page. - Go back to the home page, and click on
Notifications. The notifications received will be displayed here. - Then connect to the publisher Instance with that URL
http://<your_subscriber_ip_address>:8081 - Go to the home page of your publisher server:
http://<your_publisher_ip_address>:8081 - Click on a CPU behavior, and check the notification page of your subscriber server. A notification about the behavior should have appeared.
- Once you're done testing, you can apply
terraform destroyto clean and remove the project.
