Day 38: Deploying Containerized Applications with Amazon ECS

[Varaprasad1384]

Application is not accessible.

Though I am able to access the application, challenge 38 reports " Application is not accessible." Where is the issue ??

First, make sure you’re naming everything appropriately. When I ran the task, these were as follows; I’m working from this guide to do this.

1. Create a Private ECR Repository:

• Create a private ECR repository named datacenter-ecr to store Docker images.

2. Build and Push Docker Image:

• Use the Dockerfile located at /root/pyapp on the aws-client host.
• Build a Docker image using this Dockerfile.
• Tag the image with latest tag.
• Push the Docker image to the datacenter-ecr repository.

3. Create and Configure ECS cluster:

• Create an ECS cluster named datacenter-cluster using the Fargate launch type.

4. Create an ECS Task Definition:

• Define a task named datacenter-taskdefinition using the Docker image from the datacenter-ecr ECR repository.
• Specify necessary CPU and memory resources.

5. Deploy the Application Using ECS Service:

• Create a service named datacenter-service on the datacenter-cluster to run the task.
• Ensure the service runs at least one task.

I set these using a vars.sh file, as so:

export ECR_REPO="datacenter-ecr"
export ECS_CLUSTER="datacenter-cluster"
export ECS_SERVICE="datacenter-service"
export TASK_DEF="datacenter-taskdefinition"

This validates off a private FARGATE address; so I’m not sure you’ve configured the service correctly, even though you appear successful setting up the image – the service won’t have a public IP endpoint if you did it per spec.

Thank you @rob_kodekloud … The service is accessible using public IP as shown in my second picture. However, I didnt set the variables in vars.sh (kind of) … Really confused if we need to complete the task with only steps what KodeKloud defines (without any deviation )

Some of the tasks are “tweaky” and are hard to get right. It’s not that you have to do them one way; it’s just that there are a lot more ways “to get it wrong” This task in particular is more tweaky than most.
