public class ContainerDefinition
extends Construct

A container definition is used in a task definition to describe the containers that are launched as part of a task.

Example:

 TaskDefinition taskDefinition;
 Cluster cluster;
 // Add a container to the task definition
 ContainerDefinition specificContainer = taskDefinition.addContainer("Container", ContainerDefinitionOptions.builder()
         .image(ContainerImage.fromRegistry("/aws/aws-example-app"))
         .memoryLimitMiB(2048)
         .build());
 // Add a port mapping
 specificContainer.addPortMappings(PortMapping.builder()
         .containerPort(7600)
         .protocol(Protocol.TCP)
         .build());
 Ec2Service.Builder.create(this, "Service")
         .cluster(cluster)
         .taskDefinition(taskDefinition)
         .cloudMapOptions(CloudMapOptions.builder()
                 // Create SRV records - useful for bridge networking
                 .dnsRecordType(DnsRecordType.SRV)
                 // Targets port TCP port 7600 `specificContainer`
                 .container(specificContainer)
                 .containerPort(7600)
                 .build())
         .build();
