Create an User
Go to IAM and create a User:
Add those two roles:
Download the secret csv and keep it.
Create an ECR (Repository for images)
This time let´s use aws cli, you can do the same things you do on console with the AWS CLI. For more information on how to configure AWS CLI: https://aws.amazon.com/pt/cli/
Execute aws configure and set the credentials of the IAM user:
aws configureAWS Access Key ID [****************.com]: AKIAAsaWASDEULNQAWS Secret Access Key [None]: jPms2dFasfssdcweYsdsfwq+Default region name [None]: us-east-2Default output format [None]: json |
Command to create the repository:
| aws ecr create-repository –repository-name rest-with-spring-boot |
List the repository and get the URI value:
| aws ecr describe-repositories |
Build the image:
| docker-compose build –t rest-with-spring-boot |
Now, we can check the commands to push in console, go to ECR and “View push commands”:
Execute the steps 1, 3 and 4. Because we already built the application. Example:
| aws ecr get-login-password –region us-east-2 | docker login –username AWS –password-stdi 9999999999.dkr.ecr.us-east-2.amazonaws.com docker tag project:latest 9999999.dkr.ecr.us-east-2.amazonaws.com/project:latest docker push 999999.dkr.ecr.us-east-2.amazonaws.com/project:latest |
Now, that we have the image in our repository:
Create ECS Cluster
Next
Create a Key-pair if you don´t have it yet.
Let´s fill out the Networking session, and edit the security group
Click to edit the rules, for tests purposes we will allow everything like below:
Create cluster
Click on View Cluster:
After a few minutes, we have an instance running inside the cluster:
Creating the task
A Task is the same thing as a Pod in Kubernetes, it can hold one or more containers. Usually a task contains only one container.
Let’s go back to ECS:
Set a name:
Specify the memory and CPU:
Click on “Add Container”
you can check the image with the command “Docker images”, and then set it to the image field:
You can put 80 in the first field if you want.
And then create the task:
Creating the service
Now, we will create a Service, to manage the scaling the application. Select the task and go to “Create Service”.
Go Next until Create Service button.
Service created:
Now you can access the app with the address of the EC2 instance:
