How to connect to ECR from Fargate task in the VPC Build Docker image and push to ECR on Terraform apply

How to get current task ID/ARN from within the container?
Use Amazon ECS task metadata endpoint (Fargate). Response examples for Fargate here.
import requests

f"{os.environ['ECS_CONTAINER_METADATA_URI_V4']}/task"
).json()
logger.debug(f"Task metadata: {task_metadata}")
task_arn = task_metadata["TaskARN"]
logger.info(f"Enabling protection for task {task_arn}")
ecs_client.update_task_protection(
cluster=task_metadata["Cluster"],
tasks=[task_metadata["TaskARN"]],
protectionEnabled=True,
