Kamal2 AWS ECR docker registry/repository

AWS CLI profile in my laptop .aws/credentials is named moments configured in eu-west-1

aws ecr create-repository --repository-name mysupercoolappdockerrepo  --region eu-west-1 --profile moments

# .kamal/secrets
KAMAL_REGISTRY_PASSWORD=$(aws ecr get-login-password --region eu-west-1 --profile moments)
RAILS_MASTER_KEY=$(cat config/master.key)

# config/deploy.yml
# Name of your application. Used to uniquely configure containers.
service: mysupercoolappdockerrepo

image: mysupercoolappdockerrepo
registry:
  server: 123456789012.dkr.ecr.eu-west-1.amazonaws.com
  username: AWS
  password:
    - KAMAL_REGISTRY_PASSWORD
      
  

Sidenote (optional)

if you have volume in config/deploy.yml e.g.:

volumes:
  - "/var/apps/mysupercoolappdockerrepo:/rails/storage"
  
  

Make sure folder /var/apps/mysupercoolappdockerrepo and all files and folders in it have user 1000:1000

chown -R 1000:1000 /var/apps/mysupercoolappdockerrepo

Why ? because docker is built with 1000:1000 user group (check your Dockerfile if this is the case)
