Hello and welcome to this short lecture which will provide a high level overview of the amazon ec2 container service commonly known as amazon ecs.
Aws ecs container communication.
In this example my code in kcentral services can refer to rabbitmq container and it resolves fine.
Customers such as duolingo samsung ge and cookpad use ecs to run their most sensitive and mission critical applications because of its security reliability and scalability.
I created a single ecs cluster that has 2 services one for each of the above each with a task container.
Ecs tasks enable you to manage containers and define communication between containers use task definitions to control images cpu memory links ports and iam roles use the new iam roles definition to isolate credentials and authorization between tasks.
Whenever the client wants to talk to one of the servers it sends its.
After a cluster is up and running you can create task definitions that define which container images to run across your clusters.
Highly secure reliable and scalable way to run containers.
This simplifies container networking operations allowing tasks to run with full networking features on aws just like ec2 instances.
Tasks running on amazon ec2 container service amazon ecs can now take advantage of awsvpc mode for container networking.
Amazon ecs is a regional service that simplifies running containers in a highly available manner across multiple availability zones within a region.
Amazon elastic container service amazon ecs is a fully managed container orchestration service.
This new mode allocates an elastic networking interface to each running task providing a dynamic private ip address and internal dns name.
I defined the container name and hostname in the same way but the communication doesn t work.
Store and retrieve container images using the amazon ec2 container registry.
Deploy and manage containers with docker on amazon ec2.
As each container starts and becomes healthy ecs updates the load balancer so that it knows the address of the new container.
This service allows you to run docker enabled applications packaged as containers across a cluster of ec2 instances without requiring you to manage a complex and administratively heavy cluster management system.
This can be through an interface vpc endpoint or through your container instances having public ip addresses.
Ecs is a great choice to run containers for several reasons.
You can create amazon ecs clusters within a new or existing vpc.
Using containers to automate security deployments.
