Support Fargate Spot for Graviton for ECS/EKS

[melaraj2]

It was great to see that now Graviton2 is supported on Fargate, but we are still missing spot support. Is this coming soon?

I currently run most of my dev workloads in spot Fargate services, but I would love to switch to Graviton. However, without spot support, the cost would be much greater; it kind of beats the notion of better price-performance!

Any update on the progress here? Would be great to have this!!

Also interested in this, would be great to have the option to freely choose ARM vs. X86_64 for spot containers.

It will help a lot in cost reduction and temporary scalability.

Also looking forward to switch to Fargate Spot on ARM

[kastningj]

Looking forward to this. We use ARM64 across the board. It's sizeable lift to switch back to X64, but it would help a lot for cost reduction. Please make this a priority!

Would love to see a graviton spot

Apologies for being a bringer of bad news... but for those that are not aware and with high hopes of seeing this feature request implemented anytime soon (maybe?), someone working in the AWS containers team recently made this comment on a related Reddit thread:

I'm on the container services team at AWS. I can assure you that Fargate Spot + ARM64 is not a thing (yet). What will happen is in your service's event tab it will say that it was unable to find capacity to launch any tasks. The Spot market is basically for selling unused compute capacity (often powered by older generations of hardware) at a discount. Graviton and ARM64 instances are so new and so popular that we don't really have extra unused compute capacity to offer at a Spot discount.

If so, how he would explain that I'm perfectly using EC2 backed ECS with Spot C7G?

Because probably Fargate not use C7G.
The last time that I check, was using M5 and C5 for x86, probably the same happens with ARM64.

Today we added Graviron support for Amazon ECS / Fargate Spot compute:

Note, Fargate Spot is not available with Amazon EKS.

Great!! Already testing!

Marking this done- please create a separate one for EKS Fargate if still needed.
