Jenkins: deploy to AWS ECS with docker compose

I have some misunderstanding. I have Jenkins instance, ESC cluster and docker-compose config file to compose my images and link up containers.

After git push my Jenkins instance grabs all sources from all repos (webapp, api, lb) and makes a batch of operations like build, copy files and etc.

After that I have all folders with Dockerfiles in state "ready for compose".

And in this stage I cant get how I should ping my ESC cluster on AWS to grab all images from Jenkins and compose them with my docker-compose.yml config.

I would be glad of any useful information.

Thanks.

First, you need to push your images from the Jenkins server into ECR. Push every image individually to an independent repo.

Next, you have to create an ECS cluster. In this cluster, you create an ECS service that runs in the cluster. For this Service, you create and configure a Task Definition to run your linked containers. You don't need to use docker-compose for this: in ECS you define the links between containers in the configuration of the Task Definition. You can add several container definitions to the same Task Definition, and ECS will link them together.

You can automate all of this from your Jenkins server by attaching an Instance Profile to it that allows it to call the ECS API. In order to deploy new images, all you need to do is pushing them to their ECR repos, and create a new Task Definition pointing to them, and update the service that runs these task definitions. ECS will automatically trigger a blue-green deployment on your behalf.
