Step 1 : Containerising a bun app

https://github.com/RitikaxG/ecr-ecs-bun-app

• Create simple bun app with bun init
• Expose 2 endpoint / /health
• Create Dockerfile
• Build multi-arch docker image

docker buildx build --platform=linux/arm64,linux/amd64 -t ecr-node-app .

• Load mac arch docker image

docker buildx build --platform=linux/arm64 -t ecr-node-app --load .

• Check by running the image locally

docker run -p 3001:3001 ecr-node-app

Step 2 : Login to AWS

#1. create fresh ecr repository ( ritikaxg/ecr-ecs-nodeapp )
#2. create new user in aws with AmazonEC2ContainerRegistryFullAccess permission ( ecr-ecs-nodeuser )
#3. Installed AWS CLI locally
#4. Run command `aws configure` and put in freshly created user's access key & secret
#5. docker build
#6. docker push

• Install AWS CLI locally

  Installing or updating to the latest version of the AWS CLI - AWS Command Line Interface

• Create IAM USER & give amazonEC2ContainerRegistryFullAccess

  

• Create security credentials for that user
