A tool to automate some tasks in ECS/ECR.

Work in progress...

Prerequisites

• awscli
• working aws credentials
• environment AWS_REGION exported

How to install

Get a binary from https://github.com/edsoncelio/severinoctl/releases

Features

• Check if a tag exists in a ECR repository
• List task definition ARN revisions to a family
• Create a task definition revision to a new image version

Usage

To check if a specific image tag exists in a specific ECR repository:

severinoctl checkTag --registry my-ecr-registry --tag 1.0

If the tag exists, you will receive the following message:

✅ Tag '1.0' found! digest: <IMAGE DIGEST HERE> and repository: my-ecr-registry

Otherwise:

❌ Tag '1.0' not found, reason: <REASON> - try again!

To list all the revisions related to a specific task definition:

severinoctl listTask --name sample-app

And the output:

TaskDefinition ARN to revision 0: arn:aws:ecs:us-east-1:<AWS ACCOUNT>:task-definition/sample-app:1
TaskDefinition ARN to revision 1: arn:aws:ecs:us-east-1:<AWS ACCOUNT>:task-definition/sample-app:2
...

To create a new task definition revision to a specific image:

severinoctl updateTask --family sample-app --image myimage:v1.0.0

If the image and tag already exists in the task definition:
⚠️ The image is already registered

Otherwise:

🔍 Actual image found: myimage:v1.0.0 - New image to use: 'myimage:v2.0.0'
⌛  Creating the new revision...
🎉 Revision 'arn:aws:ecs:us-east-1:<AWS ACCOUNT>:task-definition/sample-app:19' created!

TODO

• Add tests
• Use aws sdk instead of aws cli
• Configure goreleaser
• Add option to create a ECS task definition revision (and show a diff) - partial done
