In this blog, we will explore how to redirect a domain to another domain using Amazon Route 53

Requirement

• You have a domain abc.com and DNS is configured on Route 53
• You have another domain abc.ca which needs to redirect to abc.com

Solution

For domain forwarding, you need to follow the below steps

1. Create S3 bucket with name abc.ca
2. Enable the static website hosting with redirect option
3. Create A record in Route53 for hosted zone abc.ca which will point to S3 bucket endpoint

NOTE: If you need www.abc.ca also redirects to abc.com …

To update a ECS service using script you can use the below command

Parameters required

• Cluster Name
• Service Name

aws ecs update-service --cluster ecsdeployment --service ecsdeployment-WebService-voWNHfK05HHq --force-new-deployment --region us-east-1

In some cases, this command didn’t update the service and if you need to run just one container for your service and you can have downtime then update your service as shown below :

Automation

You can easily automate this process from your pipeline. Create a shell script and run these commands

• You need to use the login command to push the images in ECR
• Build, tag and publish
• Update…

When you have multiple applications which are running inside an ECS cluster or anywhere else then how can you use just one loadbalancer for all the applications.

Using separate loadbalancer for each of the services/applications will be more expensive as each LB cost around $15/month and if you have 5 services then this would be $75/month.

Example:

You have an application which is listening on port 8080 and it requires SSL certificates.

• Application can listen on same or different port also

Solution

• Define the instance port in the Target Group
• configure the Target Group to use port 8080 or…

In this blog, we will deploy a container using docker-compose in ECS cluster.

You can follow this blog to deploy a docker container in ECS directly.

Prerequisite

1. Configure aws credential
2. Install aws cli version 2
3. Clone this git repo

Agenda:

1. Create new docker context
2. Run docker compose to create a new ECS cluster

To run it from your local workstation, first you need to set the docker context to use the ECS to run the docker commands

Create new docker context

docker context create ecs myecs
docker context ls
docker context use myecs

Create a docker-compose.yaml file and provide…

In this blog, we will deploy a docker container in Amazon ECS(Elastic Container Service) using ECR ( Elastic Container Registry)

Prerequisite

1. Configure aws credential
2. Install aws cli version 2
3. Clone this git repo
4. Local workstation ( I am using AWS EC2 instance)

Agenda:

1. Create and Push to ECR repository
2. Create a ECS cluster
3. Create a Task Definition
4. Run the task
5. Create a Service

Create a ECR repository

Go to AWS > ECR > Create a repository

Click on your repository

In this blog, we will be deploying this guestbook application using helm and add the Redis as a dependency.

Prerequisite

1. Kubernetes Cluster Setup
2. Clone this git repo

Setup a helm project

helm create guestbook
rm -rf guestbook/templates/tests

Adding a Redis Chart dependency

Chart dependencies are used to install other charts’ resources that a Helm chart may depend on.

In this example, we are using Redis as a database so we to need add this as a dependency.

First we can search the charts for redis

helm search hub redis

Now we will add the dependency section in the Charts.yaml…

In this blog, we will run a Demo of creating an AWS Lambda Function which will convert a csv file into a json file.

Prerequisite

1. Clone this git repo
2. Refer this blog for basic understanding of AWS Lambda

For this we will use S3 bucket as a source where we will store the csv file that will trigger the lambda function and convert the file in json and store it in another bucket.

We will be creating below resources. You can refer the git repo

1. Create source S3 bucket
2. Create target S3 bucket
3. Create a lambda function in python
4. …

In this blog we will learn about AWS Lambda and create a lambda function.

What is Serverless Compute ?

Serverless compute is a cloud computing execution model in which the AWS Cloud acts as the server and dynamically manages the allocation of machine resources.

• AWS Lambda is the AWS serverless compute platform that enables you to run code without provisioning or managing servers.
• With AWS Lambda, you can run code for nearly any type of application or backend service — with zero administration
• Only upload your code, and AWS Lambda performs all the tasks you require to run and scale your code with high…
