Registration procedure

Here's a summary of Pushing images to Amazon Elastic Container Registry It is what I did. There were times when I couldn't pass the command, so I've written about it.

Preparation

aws configure It is necessary to execute configure when using aws cli. If it has already been set, you can skip it. This is how to set up the AWS CLI and you will be prompted for the following four pieces of information.

--Access key ID --Secret access key --AWS Region --Output format

It is recommended to specify --profile as shown below when configuring. Here, I named it prf-name.

aws configure --profile prf-name

If you set this, when you use the aws command, if you specify the setting information created with --profile like the following, you can easily tell the command where you want to access. is.

aws s3 ls --profile prf-name

If you do not specify --profile, you will not be able to specify the authentication information as shown below, so be careful with aws configure first.

Unable to locate credentials. You can configure credentials by running "aws configure"

If you want to check the list of created profiles, execute the following. This is convenient when you forget the name you set.

aws configure list-profiles

Create an Amazon ECR repository

aws ecr create-repository --repository-name your-repository-name --region region --profile prf-name

your-repository-name: Favorite repository name region: Region (eg ap-northeast-1)

There is no description on the official website, but if you do not describe --profile, the authentication error message mentioned earlier will be displayed.

Tag the image and push it to Amazon ECR

1. Create an Amazon ECR repository

aws ecr create-repository --repository-name hello-repository --region region

hello-repository: repository name region: Region (eg ap-northeast-1) output:

{
    "repository": {
        "registryId": "aws_account_id",
        "repositoryName": "hello-repository",
        "repositoryArn": "arn:aws:ecr:region:aws_account_id:repository/hello-repository",
        "createdAt": 1505337806.0,
        "repositoryUri": "aws_account_id.dkr.ecr.region.amazonaws.com/hello-repository"
    }
}

1. Tag the hello-world image with the value of repositoryUri from the previous step.

docker tag hello-world aws_account_id.dkr.ecr.region.amazonaws.com/hello-repository

1. Run the aws ecr get-login-password command

aws ecr get-login-password --profile prf-name | docker login --username AWS --password-stdin aws_account_id.dkr.ecr.region.amazonaws.com

output:

Login Succeeded

Push the image to Amazon ECR using the value repositoryUri from the previous step.

docker push aws_account_id.dkr.ecr.region.amazonaws.com/hello-repository

Confirmation of pushed image Check the pushed images using list-images

aws ecr list-images --repository-name hello-repository --region region --profile prf-name
