What other features are you missing from ECS?

Not the OP, but I'm missing in no particular order(and some of these may be on offer now): * Secret storage * Pet sets(coming along in k8s) * Leader election * Persistent volumes It looks like Blox can address some of this stuff, but kubernetes is providing this stuff OOTB.. It's also locked to vendor-specific service offerings. This isn't to say Kubernetes doesn't have room for improvement; its AWS integrations coul…

Hi - I do a lot of work on Kubernetes on AWS. We definitely have room for improvement - and not just in the glib "there's always room for improvement" way.

But: We don't support ALB yet because we haven't actually found a compelling use-case for it. Ingress on Kubernetes seems to do everything ALB can, but without the limitations. At least that's what we've thought so far, so if you have a use case do open an issue explaining it, and we can look at adding it :-)

GRPC requires http2 which is only supported by ALB and not ELB. Our services are mostly GRPC so lack of ALB means we can't use k8s out of ths box on AWS if that adds any fuel to the fire.

I'm not sure the last time the issue was looked at, but I could consolidate some of the benefits that have brought up here:

* Websockets support

* Http/2 support

* Layer 7 routing + Route to specific ports(stop sending all traffic to all nodes and preserve source ip)

* Request tracing(recently added to ALB)

I hope this doesn't sound too negative, and I KNOW you do a TON of work on this stuff, but there often seems a disconnect between the people working on the kubernetes integrations and the feedback coming through from people trying to run businesses on AWS. Which happens; it's tough to be in both roles if your business isn't infrastructure.

I am really glad to see this kind of thing. I built an important project on ECS at the beginning of this year, and it was an extremely frustrating uphill battle, and I consider myself a seven or eight out of ten with containers and container orchestration in general. I wanted so much to enjoy working with ECS, especially because it was the first major Docker project that particular client was working with, and I wanted to blow their minds. The choice to build on ECS was the client's (not mine), and ECS made their introduction to container orchestration lukewarm at best. Because of those obstacles, I have been recommending against using ECS. Seems like it's time for me to evaluate ECS once more to see how far it's come along.

As a heavy grpc user, I don't think ALB supports it due to a lack of trailer support. You're probably going to just use a TCP load balancer if you want grpc services behind a load balancer.

I am in the same boat: burned, early on, when playing with ECS. Given this announcement, and Netflix announcing they will contribute to the project, it's time to take a second look.

I also want GRPC for my own stuff; ELB will work fine (in TCP mode), but I also want it to work through ingress. My understanding is HTTP2/GRPC support is coming to ingress - that aledbf has already implemented it, and it will be coming to the "official" repo soon; ingress is becoming a top-level project and there's some reshuffling that has to happen, but then aledbf has some great stuff in the pipeline.

You can use ELB in TCP mode and use the nginx ingress controller (http2 works ootb) https://github.com/kubernetes/contrib/tree/master/ingress/co...

Please check the nginx ingress controller (you can use https://github.com/kubernetes/kops/blob/master/addons/ingres... in aws) The only missing piece is "Request tracing(recently added to ALB)"
