ECS run_task in fargate mode

[shubozhang]

Is there a way to mock ecs run_task in fargate mode? Currently, I only find EC2 mode. Thanks !

Thanks for opening.

Not today, but I am going to set this as a feature request.

Seconding this!

It's been a while since this request, just wondering if it's still on the roadmap? Thanks!

Hi @mracette, moto is really a community-driven project, so there's no roadmap as such. Features just get added by people who want to contribute/really need that specific feature. So if somebody feels like developing this - PR's are always welcome!

There's been quite some improvements to ECS since this was raised, including in #3584, and we do have internal tests that call run_task(launchType="FARGATE"), so I'm going to assume that this now works as intended.

I'll close this, but do let us know if there are still issues with our current implementation.

@bblommers Unfortunately, it still doesn't work, I just faced the issue in 3.1.4 release.

The internal test calling run_task(launchType="FARGATE") actually registers instance before, so simulates EC2 launch type, not the Fargate launch. If you drop client.register_container_instance from the test, it will stop to work, as run_task assumes EC2 run. I think I can contribute a fix for this case.

Hi @szczeles, thanks for letting us know. A PR would be very welcome - let me know if you need any help around this!
