ECS task definitions should not share the host's process namespace¶

This control checks if AWS ECS task definitions are configured to share a host's process namespace with its containers. The control fails if the task definition shares the host's process namespace with the containers running on it.

How to fix¶

Attribute pid_mode of aws_ecs_task_definition must satisfy condition: not_equals.

Implementation options¶

Choose the option that matches how you manage Terraform. All options satisfy this control.

Option 1: Terraform AWS provider resources¶

If you manage resources directly, configure the relevant Terraform AWS provider resources to meet this control. See docs for the resources involved: aws_ecs_task_definition.

resource "aws_ecs_task_definition" "this" {
  container_definitions    = jsonencode([{ name = "app", image = "nginx:latest", essential = true, portMappings = [{ containerPort = 80 }] }])
  cpu                      = "256"
  family                   = "pofix-example"
  memory                   = "512"
  network_mode             = "awsvpc"
  requires_compatibilities = ["FARGATE"]
}
