Search by TAG for list of services (ECS)

Question

I have an ECS deployment where I need to re-deploy the services based on some configuration server (env from S3). The task definition or image does not change, so I am planning on using a lambda to list the containers that need to restart/redeploy and use aws cli for the same.

To list all the services that need to be re-started I maintain a manual dependency list. I am thinking of automating this with tags. Is it possible to list all services based on tag (say I need to re-start all services that has tag db-service when some db related env change (in S3) happens). Since search by tag is possible is there some way to do a get-by-tag.

The only way I saw is to describe all the resources and use the tags to narrow down for the necessary task. Is there a more efficient way? Or a better way for the use-case.

Answer

You can use Tag Editor to find resources to tag:

Answer

Besides using [Tag Editor](https://docs.aws.amazon.com/tag-editor/latest/userguide/find-resources-to-tag.html) to search for resources based on tag, there is also the option to use [AWS Resource Explorer](https://docs.aws.amazon.com/resource-explorer/latest/userguide/welcome.html) to search for tags. However, I believe what you want is to automate that deployment. For that you can use [AWS Systems Manager to remotely manage ECS instances.](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ec2-run-command.html). You can also leverage deploying via tag with [CodePipeline](https://repost.aws/questions/QUkA4bU0tUTBSKMTgz4DlyWw/how-to-perform-codepipeline-ecs-deployment-based-on-git-tag).
