Ah that’s a super nice feature. I’m mostly familiar with AWS who don’t have a neat way of doing this, you end up with a bespoke solution either with lambdas pushing to shared volumes or just polling s3 for updates.
If you are using kubernetes, you can mount the secret/ConfigMap as a volume and it will be updated automatically when changes occur. Then your application merely watches the file for updates.
Being on AWS, using EKS feels like overkill when you're talking $75/month just for having it managed by AWS. This doesn't work with ECS, unfortunately, or if you're just running docker on EC2.
AWS has a native service for this called AppConfig and has agents that can pull and cache flag values so your services only need to make localhost requests.
