Amazon Elastic Container Registry
Amazon Elastic Container Registry is used to store docker images in Amazon AWS cloud.
To create a repository using awscli command line tool, run
|
1 |
aws ecr create-repository --repository-name sok-repository --region ap-southeast-1 |
In Amazon AWS console, you can see the newly created repository by going to “Elastic Container Registry” page in the region where you created the repository.
https://ap-southeast-1.console.aws.amazon.com/ecr/repositories?region=ap-southeast-1
To see the details from command line, run
|
1 |
aws ecr describe-repositories --region ap-southeast-1 |
From the command, you will see repositoryUri, this is used to push your docker images.
I have following docker images
