After that we define the lob group and the actual ECS cluster. this code vork fine in Terraform v0.9.2 A container then is a running instance of that image. On a first glance, the only thing that I needed was to specify on the task definition the version of Fargate to 1.4.0, but since I never worked with EFS before, and the Terraform docs forget to mention that you need to implement others resources to work with EFS properly, I suffered a little bit to figure out what I needed to get done.
