UPDATE_LOCAL_IMAGE

DESCRIPTION

This project was created to keep the images that are in the AWS ECR (Amazon Elastic Container Registry) updated with the official images.

MOTIVATIONS

We were working on a way to centralize the images in our ECR repository, to implement a security lock to prevent external image downloads. We ran into a problem, we would have to manually update these images in our repository on a regular basis or they would get out of date. Thus came the idea of the UPDATE-LOCAL-IMAGE project.

FUNCTIONALITIES

• Connections:
  • AWS ECR Login: The module logs in to AWS ECR with the proper credentials.
  • AWS ECR logout: The module logout at the end of execution.
• Download images: Downloads ECR and external images.
  • Image hash comparison: The module extracts the hash of the image that is in the AWS ECR and in the external image and compares them.
• Preparation of images:
  • Creating a list of repositories: The module creates a list with all the repositories that contain the name "base/image".
  • Creation of a list of tags: The module creates a list of all the tags that exist within each repository.
  • Image TAG: Tag creation.
  • Image Push: Sends the image to AWS ECR.
• Send notifications: Send message with execution summary to discord
