Building images and pushing them to private registries

• Create a linux vm
• Install docker
• Install aws cli and authenticate
• INstall azure cli and authenicate
• Clone the repo

git clone https://github.com/Azure-Samples/aks-store-demo.git

Azure Container Registry

• Container Registry Creation
• In the docker compose file use the similar syntaxes as shown below

image: ${ACR_SERVICE}/learning/order-service:${IMAGE_TAG:-latest}

Elastic Container Registry

• Lets set the following variables

export AWS_REGION=ap-south-1
export AWS_ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)
export ECR_REGISTRY="${AWS_ACCOUNT_ID}.dkr.ecr.${AWS_REGION}.amazonaws.com"
export IMAGE_TAG=v1.0.0
echo $IMAGE_TAG
echo $ECR_REGISTRY

• We need to create repositories once

aws ecr create-repository \
  --repository-name learning/ai-service \
  --region "$AWS_REGION"

aws ecr create-repository \
  --repository-name learning/makeline-service \
  --region "$AWS_REGION"

aws ecr create-repository \
  --repository-name learning/order-service \
  --region "$AWS_REGION"

aws ecr create-repository \
  --repository-name learning/product-service \
  --region "$AWS_REGION"

aws ecr create-repository \
  --repository-name learning/store-admin \
  --region "$AWS_REGION"

aws ecr create-repository \
  --repository-name learning/store-front \
  --region "$AWS_REGION"

aws ecr create-repository \
  --repository-name learning/virtual-customer \
  --region "$AWS_REGION"

aws ecr create-repository \
  --repository-name learning/virtual-worker \
  --region "$AWS_REGION"
