Dynamically Changing docker compose service image?-CodePudding

We have a docker-compose file with service like

services:
    utils-microservice:
        container_name: utils-microservice
        image: <Masked>.dkr.ecr.ap-south-1.amazonaws.com/utils-microservice:<Some Tag>
        ports:
        - '1024:1024'
        env_file:
        - './envs/utils-microservice.env'

Now, what we want to do?

Once CI Pushes a new TAG to ECR, We can run a shell script to achieve the following

1 Stop the container
2 Replace the utils-microservice:<Some Tag> to utils-microservice:<Some New Tag>
3 Restart the service with new tag!

Is it achievable? we are not looking to complicate using docker swarm or k8's!

It’s possible to use environment variables in your shell to populate values inside a Compose file:

web: image: "webapp:${TAG}"
