Are there tables of wastage rates for different fruit and veg? Using kaniko to build your containers and Jenkins to orchestrate build pipelines, you can operate your entire CD infrastructure without any EC2 instances. I've already tested deploying onto EC2 and fronting with an ALB, that works great but our team uses ECS so heavily that I've been requested to do this in ECS since it would be good experience for future projects. Now, lets list the resources we need to run our application: Now, without further ado, lets jump into the stack. Its not obvious from the docs where this NetworkConfiguration section gets specified, but it doesnt go in the Task Definition json, it gets passed when you create the Service using the Task Definition.
