Cant I use Amazon ECR registry the same was as I am creating private registry?
Whitelist the private registry by adding to daemon.json file and restart docker service
docker push <ecr/registry/ip>/<image_name>
docker pull <ecr/registry/ip>/<image_name>
we need to use aws cli, but I dont want to use the same and handle it via private registry method.
Any leads?
You will need to use aws cli,
aws ecr get-login --registry-ids 012345678910 023456789012
This command will output one or more docker login commands for you that includes a user, a password and the specific registry urls for the registries that you requested, then you can eval the output or run the command(s) manually, after that you can use docker pull and docker push.

I have created one ECR repository as public. Now, from my on-premises docker server, I build the image and I wanted to push the image in AWS ECR as public image. AWS has given option view push option but It did not work, getting below error while running the below command.
**docker login -u AWS -p $(aws ecr get-login-password --region ap-northeast-2)
public.ecr.aws/m8r0s3o9**
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: login attempt to https://public.ecr.aws/v2/ failed with status: 400 Bad Request
For private repository it works fine for me.
Any suggestion would be highly appreciable, do i need to add any role/policy to my aws user?
Thanks for your feedback guidance.
I found the issue, I was referring "view push command instructions" where respective region show in the command.
But for public repository need to run below command always.
aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws/<your repo name>
so in short, When authenticating to a public registry, always authenticate to the us-east-1 Region when using the AWS CLI.
It resolved my issue and i was able to push the docker images in ECR. Rest command are same.
I'm trying to log in to AWS ECR with the Docker login command. I can get a password with the AWS CLI with the command aws ecr get-login-password but when piping this into the docker login command I get the following error:
Error saving credentials: error storing credentials - err: exit status 1, out: `not implemented`
The command I am running is the one recommended in the AWS ECR documentation:
aws ecr get-login-password --region us-east-1 | docker login --username AWS --password-stdin account_id_redacted.dkr.ecr.us-east-1.amazonaws.com/blog-project
I'm running the latest version of AWS CLI as of this question, 2.0.57.
I'm running Docker version 2.4.0 on macOS 10.14.6
Has anyone else run into this issue, and if so have they found a solution?
I've definitely achieved this in the past, but I wonder if there is an issue between the latest versions of Docker and the AWS CLI...
I'm not 100% sure what the issue was here, but it was something to do with the Docker credentials helper.
I installed the Docker credentials helper for macOS, changed the credsStore parameter in ~/.docker/config.json to osxkeychain. That fixed the issues.
I had similar issue, seems like my ~/.docker/config.json was totally messed after work with multiple repos / hubs.
So I just wiped out all the content in this file leaving it empty and rerun aws ecr get-login-password | docker login ... which automatically populated config with appropriate values.
I had this issue on macOS from
.docker/config.json
remove
"credsStore" : "ecr-login"
This resolved the issue for me
if anybody has the same problem on windows then go to C:\Users folder and in the .docker folder remove the config.json file.
it might fix your problem
I believe this is the intended result (sorta). The point of using amazon-ecr-credential-helper is to not need to use docker login. You should instead configure the AWS CLI with your profile credentials (mine: myprofile). Then, you would just need to slightly modify your scripts.
For example, in ECR the AWS given steps to upload a docker image are:
Retrieve an authentication token and authenticate your Docker client
to your registry. Use the AWS CLI:
aws ecr get-login-password --region us-east-2 | docker login --username AWS --password-stdin XXXXXXXXX.dkr.ecr.us-east-2.amazonaws.com
Note: If you receive an error using the AWS CLI, make sure that you have the latest version of
the AWS CLI and Docker installed.
Build your Docker image using the
following command. For information on building a Docker file from
scratch see the instructions here . You can skip this step if your
image is already built:
docker build -t toy_project .
After the build completes, tag your
image so you can push the image to this repository:
docker tag toy_project:latest XXXXXXXXX.dkr.ecr.us-east-2.amazonaws.com/toy_project:latest
Run the following command to push this image to your newly created AWS
repository:
docker push XXXXXXXXX.dkr.ecr.us-east-2.amazonaws.com/toy_project:latest
However, you would want to skip step 1. The reason is that if you configured aws cli (i.e. aws configure --profile myprofile) then your credentials will be stored. So you can skip to step 2.
On the 4th step, you simply need to add AWS_PROFILE, just like below
AWS_PROFILE=myprofile docker push XXXXXXXXX.dkr.ecr.us-east-2.amazonaws.com/toy_project:latest`
With amazon-ecr-credential-helper, you no longer need to use docker login or worry about storing credentials, that is the point of amazon-ecr-credential-helper. However, this may not be the best solution for you if you need to actively use docker login in your scripts.
Note: my ~/.docker/config.json looks like
{
"credsStore": "ecr-login"
}
I was getting the same error while running this command on MacOS.
Error possibly occurred because that particular location didn't have the appropriate permissions for users read/write/execute.
Also while I was doing
% docker ps
It was giving an error as: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
What I did:
% sudo chmod 777 /var/run/docker.sock
This gave all the required permissions to that location.
Hope it would help!
I have an ECR and EC2 instance running docker. What I want to do is to pull images without doing docker login first.
Is it possible at all? If yes what kind of policy should I attach to EC2 instance and/or ECR repo? I did a lot of experiments, but did not succeed.
And please - no suggestions on how to use aws get-login. My aim is to get rid of it by using IAM policy/roles.
To use an EC2 Role without having to use docker login, https://github.com/awslabs/amazon-ecr-credential-helper can be used.
Place the docker-credential-ecr-login binary on your PATH and set the contents of your ~/.docker/config.json file to be:
{
"credsStore": "ecr-login"
}
Now commands such as docker pull or docker push will work transparently.
My aim is to get rid of it by using IAM policy/roles.
I don't see how this is possible since some form of authentication is required.
Can we pull images from AWS ECR Repository on an AWS EC2 instance running docker assigning AWS EC2 instance role/policy and AWS ECR Repository permission that provides access to ECR.
I have currently provided all permissions but the error I am getting is "unauthorized: authentication required".
Let me know if this is possible.
you can actually skip the docker login step, even aws ecr get-token which still did the docker login, using ecr credential helper.
with the helper, just config the docker:
{
"credHelpers": {
"aws_account_id.dkr.ecr.region.amazonaws.com": "ecr-login"
}
}
refer to: https://lwpro2.wordpress.com/2019/10/30/authenticating-amazon-ecr-repositories-for-docker-cli-with-credential-helper/
Run the below command in your cron and cron will refresh your login credentials.
COMMAND=`eval aws ecr get-login --region us-west-2`
echo `eval $COMMAND`
So you can avoid any login to ecr itself and access seamlessly all the time.
So I have a docker container running jenkins and an EC2 registry on AWS. I would like to have jenkins push containers back to the EC2 registry.
To do this, I would like to be able to automate the aws configure and get login steps on container startup. I figured that I would be able to
export AWS_ACCESS_KEY_ID=*
export AWS_SECRET_ACCESS_KEY=*
export AWS_DEFAULT_REGION=us-east-1
export AWS_DEFAULT_OUTPUT=json
Which I expected to cause aws configure to complete automatically, but that did not work. I then tried creating configs as per the AWS docs and repeating the process, which also did not work. I then tried using aws configure set also with no luck.
I'm going bonkers here, what am I doing wrong?
No real need to issue aws configure instead as long as you populate env vars
export AWS_ACCESS_KEY_ID=aaaa
export AWS_SECRET_ACCESS_KEY=bbbb
... also export zone and region
then issue
aws ecr get-login --region ${AWS_REGION}
you will achieve the same desired aws login status ... as far as troubleshooting I suggest you remote login into your running container instance using
docker exec -ti CONTAINER_ID_HERE bash
then manually issue above aws related commands interactively to confirm they run OK before putting same into your Dockerfile
