ContainerDefinition
A container definition is used in a task definition to describe the containers that are launched as part of a task.
Example
ts
declare const taskDefinition: ecs.TaskDefinition;
declare const cluster: ecs.Cluster;
// Add a container to the task definition
const specificContainer = taskDefinition.addContainer('Container', {
image: ecs.ContainerImage.fromRegistry('/aws/aws-example-app'),
memoryLimitMiB: 2048,
});
// Add a port mapping
specificContainer.addPortMappings({
containerPort: 7600,
protocol: ecs.Protocol.TCP,
});
new ecs.Ec2Service(this, 'Service', {

taskDefinition,

notes
If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, then its failure does not affect the rest of the containers in a task. All tasks must have at least one essential container.
If this parameter is omitted, a container is assumed to be essential.

notes
When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first.
At least one of memoryLimitMiB and memoryReservationMiB is required for non-Fargate services.

This property can't be used if enableRestartPolicy is set to false.
You can set a minimum restartAttemptPeriod of 60 seconds and a maximum restartAttemptPeriod of 1800 seconds.

notes · 1 parameter · returns
Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.
Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.
Parameters
xxxxX— Any object.
Returns: true if x is an object created from a class which extends Construct.
