Posted on by Jay Jo

Install awscli (Mac)

brew install awscli
aws --version

aws configure
AWS Access Key ID: ${Access key ID}
AWS Secret Access Key: ${Secret access key}
Default region name: ${region} // ap-northeast-2(seoul)
Default output format: json

Create ECR

1. go to https://console.aws.amazon.com/ecr/
2. choose to get started.
3. choose tag immutability
4. scan on push

Login ECR with awscli

After you have installed and configured the AWS CLI, authenticate the Docker CLI to your default registry. That way, the docker command can push and pull images with Amazon ECR. The AWS CLI provides a get-login-password command to simplify the authentication process.
To authenticate Docker to an Amazon ECR registry with get-login-password, run the aws ecr get-login-password command. When passing the authentication token to the docker login command, use the value AWS for the username and specify the Amazon ECR registry URI you want to authenticate to. If authenticating to multiple registries, you must repeat the command for each registry.

Get-login-pawword

aws ecr get-login-password --region ap-northeast-2 | docker login --username AWS --password-stdin 713814976737.dkr.ecr.ap-northeast-2.amazonaws.com

Create a Repository

repository name: k8s-board-fe, k8s-board-api

aws ecr create-repository \ --repository-name k8s-board-fe \ --image-scanning-configuration scanOnPush=true \ --region ap-northeast-2
aws ecr create-repository \ --repository-name k8s-board-api \ --image-scanning-configuration scanOnPush=true \ --region ap-northeast-2
  • Seoul: ap-northeast-2

Docker Push

docker build -t 713814976737.dkr.ecr.ap-northeast-2.amazonaws.com/k8s-board-fe:v1 .
docker push 713814976737.dkr.ecr.ap-northeast-2.amazonaws.com/k8s-board-fe:v1

docker build -t 713814976737.dkr.ecr.ap-northeast-2.amazonaws.com/k8s-board-api:v1 .
