Hi @dmarkey, would you possibly tell us what side-cars do you want to run today?

[dmarkey]

For example, a django app would routinely be deployed with 2 containers, one with uwsgi(application server) and one nginx(static assets). This is pretty common.

[toricls]

Thanks! I'm not a python guy but any reason that you don't use CF + S3 for static assets instead of returning them from containers?

[dmarkey]

This is just one example.. loads of use-cases for sidecars.

This is the same for PHP Laravel applications Nginx+PHP-FPM as two containers. We have a few clients who are doing this and would benefit from apprunner

1 - Integrations. It would be possible to connect apps with App Mesh (Envoy), X-Ray (daemon) and Secrets Manager (Dapr backend) without waiting for native integrations.

2 - Language agnostic composability. It would be possible to implement stuff like oath2 without touching code. I work in a polyglot shop and doing that with Fargate is a huge win for us. We solve our problems once, not for every language and framework.

3 - FOMO. Sidecars are becoming a common pattern with the emergence of K8s and using a platform without support for those might block us from using shiny new technologies.

The AWS OpenTelemetry Collector (https://hub.docker.com/r/amazon/aws-otel-collector) is another example usage. I can't see a secure way of using this right now as AppRunner doesn't support VPCs either. The key part is that it isn't just for convenience, a sidecar also allows private communication between the containers.

Like mentioned above, integration with OTEL collector, Datadog integrations, Fluentbit sidecar..
