💡 Hint

Common Mistakes

Using EC2 launch type instead of Fargate

Confusing Lambda with Fargate

The launch type FARGATE tells ECS to run the container without managing servers.

💡 Hint

Common Mistakes

Using bridge or host network mode which are for EC2 launch type

Setting network mode to none

Fargate requires the awsvpc network mode to assign each task its own elastic network interface.

Fix the error in the task definition to specify CPU units for a Fargate task.

AWS

"cpu": "[1]"

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using CPU values not supported by Fargate

Using values too large or invalid strings

Fargate CPU values must be one of the allowed values like 256, 512, 1024, etc. 256 is the smallest valid CPU unit.

Fill both blanks to define memory and CPU for a Fargate task in the task definition.

AWS

"memory": "[1]",
"cpu": "[2]"

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing incompatible CPU and memory values

Using memory less than 512 MB

Memory and CPU must be valid Fargate values. Here, 512 MB memory and 256 CPU units are a valid combination.

hard

Fill all three blanks to configure container port mapping and protocol for a Fargate service.

AWS

"portMappings": [{
  "containerPort": [1],
  "hostPort": [2],
  "protocol": "[3]"
}]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Setting hostPort equal to containerPort in Fargate

Using UDP protocol for HTTP services

For Fargate, hostPort must be 0 to allow dynamic assignment. Container port 80 is common for HTTP. Protocol is usually TCP.
