I'm just getting started with docker. I'm following the instructions specified here https://docs.docker.com/windows/step_one/
I installed docker (1.10.2) on windows 10 & ran docker run hello-world . But, I'm getting an authentication error while the tutorial doesn't mentioned anything about it.
Here's the message I received.
$ docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Authentication is required: Get https://registry-1.docker.io/v2/library/hello-world/manifests/latest: unauthorized: incorrect username or password.
See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.
I searched google & here, but couldn't find anything similar to this error message.
Thanks!
Please run docker login at first time when you run any other docker commands.
You can log into any public or private repository for which you have credentials. When you log in, the command stores encoded credentials in $HOME/.docker/config.json on Linux or%USERPROFILE%/.docker/config.json on Windows.
If you login through your emailId it does not works.
On windows login using your docker hub id.
You can access by your username.
Probably it can happen if you were logged in before, by console or by kitematic.
You can try docker logout if you want use docker without auth.
In this case Authentication is required: shouldn't appear again.
I have solved this issue in macOS Mojave (version : 10.14.3)
docker login
Login with your username not email id then its working fine.
On macOS you need to login from the commandline using
docker login
Also you must use your username and not your email
on ubuntu:
docker login
so if you don't know your username password, you probably haven't created one.
what you should do, is go and create an id on docker
visit: official docker webpage
just like any other github accout ,they will ask you for the username, provide one and they will authenticate same as github, once done , put your email and password. verify it and you are now good to go.
ok! now coming to the point...
if you were facing the problem like the problem statement ,
just do
docker login
enter username and password, that you just provided .
you will be displayed ,"LOGIN succeeded"
now run this command
docker run hello-world
beware of the dash '-' sign , i myself stuck with this issue, and you are done.
thanks:)
run docker login to execute any other docker commands. or just logout if you want to use public hubs docker logout
For worked trying docker logout and then docker login with the proper credentials
For those who logged in via their email address associated with their account during the Docker desktop installation process - this problem seems to occur because the terminal has also stored those credentials, but for some reason it only accepts login's via your actual username.
If you go to DockerHub you should see it in the upper right corner.
Try running docker login with that username, and you should be all set!
docker login
# username from dockerhub
# the same password
Setting my vNAT for docker dns server to 8.8.8.8 resolved my issue on windows just try might help thanks

I'm trying to push an image to my gitlab registry which i previously built with success.
docker login registry.gitlab.com
I give the credentials and it returns me a "Login Succeeded"
Then, as always, i do a
docker push registry.gitlab.com/username/registry/base:latest
And it ends with
unauthorized: authentication required
i already tried to
docker logout registry.gitlab.com
and login again.
The process can be found here, it's pretty simple
link to github/gitlabhq
I'm used to do it like that, first time i face the issue, don't understand
Any help appreciated !
Ensure that your account has read/write access to the registry you are trying to access. What you might need to do is to create a new Access Token as there is a difference between API/Access tokens and your "normal" user password. Use this access token as described in the documentation (https://github.com/gitlabhq/gitlabhq/blob/master/doc/user/packages/container_registry/index.md#authenticate-with-the-container-registry)
docker login registry.example.com -u <username> -p <token>
The token can be created by going to Edit Profile -> Access Tokens -> Select Scopes -> Ticking off 'Read registry' & 'Write registry'
The Gitlab support told me this is due to a native limitation of the token duration.
You cannot customize this duration in Saas mode.
So pushing large image results in auto logout.
Recently got a new Mac, and now I am struggling to push docker containers to GCR - receiving the error:
unauthorized: You don't have the needed permissions to perform this operation, and you
may have invalid credentials. To authenticate your request, follow the steps in:
https://cloud.google.com/container-registry/docs/advanced-authentication
Commands that led to this error:
docker build -t our-node-container ./
docker tag our-node-container gcr.io/our-gcp-project/our-grc-images-directory
docker push gcr.io/our-gcp-project/our-grc-images-directory
Confirming that:
I have a GCP account with billing, have enabled the Container Registry API and installed Cloud SDK, and have Docker installed.
I have authenticated with gcloud auth login, which opened a window where I selected my email address associated with the GCP account. It led to this page.
and afterwards, I ran gcloud config set project our-gcp-project. I have closed my terminal window and attempted to docker push again, but continue to get this unauthorized error. How else can I troubleshoot this in an effort to solve the problem?
As is standard, we solved the issue just moments after posting the question. Rather than deleting the question, I'll post an answer incase anyone runs into same issue.
We simply missed the last step, which was to run gcloud auth configure-docker to update the config file in /home/.docker/config.json
I have set up gitlab locally on ubuntu laptop per some help from this post. My set up is 100% exact to per that post. When I ran docker-compose up and visited localhost:54321 I was shown a screen to 'update my password'. I entered a new password then got taken to the sign in page where I clicked to sign up with a new account. I entered my name, email and password and hit register. I then saw this message:
I'm confused since I'm hosting gitlab locally via docker.Who is my gitlab administrator?!
How can I register on a locally hosted gitlab instance via docker? My ultimate goal is just a hello world - I'd like to explore the gitlab interface and see what the tool is all about.
The initial admin user for the GitLab CE is root.
In the GitLab Docker container path /etc/gitlab, there will be a file called "initial_root_password". Cat the content and you can got the initial password of the user root
Steps:
Assume the docker container name is gitlab_web_1
Go to the Docker container: docker exec -ti gitlab_web_1 /bin/bash
List item: cat /etc/gitlab/initial_root_password
Once you login with the user root successfully, you can try to manage the user account, and you can also use your own account to login.
Based on This Page
https://forum.gitlab.com/t/after-gitlab-ce-installation-on-ubuntu/32896
Username and Password default Administrator after Install Gitlab-ce:
Username: root
Password: 5iveL!fe
When opening the web interface after first running the container, you are prompted to 'change password'. Enter a password then on the next page enter username 'root' and the password you just created. I had to rerun the container and first empty everything in the set up directories. Emptied everything in data/, logs/ and config/ and then docker-compose up. That allowed me to login
I'm trying to push my docker image to google container image registry but get an error which says I do not have the needed permission to perform this operation.
I have already tried gcloud auth configure-docker but it doesn't work for me.
I first build the image using:
docker build -t gcr.io/trynew/hello-world-image:v1 .
Then I'm trying to attach a tag and push it:
docker push gcr.io/trynew/hello-world-image:v1
This is my output :
The push refers to repository [gcr.io/trynew/hello-world-image]

To authenticate your request, follow the steps in:
https://cloud.google.com/container-registry/docs/advanced-authentication
Google cloud services have specific information how to grant permissions for docker push, this is the first thing you should have a look I think, https://cloud.google.com/container-registry/docs/access-control
After checking that you have sufficient permissions you should proceed with authentication with something like:
gcloud auth configure-docker
See more here: https://cloud.google.com/container-registry/docs/pushing-and-pulling
If you are running docker as root (i.e. with sudo docker), then make sure to configure the authentication as root. You can run for example:
sudo -s
gcloud auth login
gcloud auth configure-docker
...that will create (or update) a file under /root/.docker/config.json.
(Are there any security implications of gcloud auth login as root? Let me know in the comments.)
In order to be able to push images to the private registry you need two things: API Access Scopes and Authenticate your VM with the registry.
For the API Access Scopes (https://cloud.google.com/container-registry/docs/using-with-google-cloud-platform) we can read in the official documentation:
For GKE:
By default, new Google Kubernetes Engine clusters are created with
read-only permissions for Storage buckets. To set the read-write
storage scope when creating a Google Kubernetes Engine cluster, use
the --scopes option.
For GCE:
By default, a Compute Engine VM has the read-only access scope
configured for storage buckets. To push private Docker images, your
instance must have read-write storage access scope configured as
described in Access scopes.
So first, verify if your GKE cluster or GCE instance actually has the proper scopes set.
The next is to authenticate to the registry:
a) If you are using a Linux based image, you need to use "gcloud auth configure-docker" (https://cloud.google.com/container-registry/docs/advanced-authentication).
b) For Container-Optimized OS (COS), the command is “docker-credential-gcr configure-docker” (https://cloud.google.com/container-optimized-os/docs/how-to/run-container-instance#accessing_private_google_container_registry)
Windows / Powershell
I got this error on Windows when I was trying to run docker push from a normal powershell window after authenticating in the google cloud shell that had opened when I installed the SDK.
The solution was simple:
Start a new powershell window to run docker push after running the gcloud auth configure-docker command.
Make sure you've activated the registry too:
gcloud services enable containerregistry.googleapis.com
Also Google has a tendency to jump to a default account (maybe your personal gmail) which may or may not be the one you want (your business email). Make sure if you're opening any links in a browser that you're in the correct Google account.
I'm not exactly sure what's going on yet because I'm brand new to docker, but something got refreshed when starting a new Powershell instance.
as noted https://stackoverflow.com/a/59799035/26283371 there appears to be a bug in the Linux version of cloud sdk where authentication fails using the standard authentication method (gcloud auth configure-docker). Instead, create a JSON keyfile per this and that tends to work.
I still can't get the gcloud auth configure-docker helper to work. What did was authenticating with an access token, like so
gcloud auth print-access-token | docker login -u oauth2accesstoken --password-stdin https://HOSTNAME
where HOSTNAME is gcr.io, us.gcr.io, eu.gcr.io, or asia.gcr.io. (Be sure to include https://, otherwise it won't work).
You can view options for print-access-token here.
First thing, Make sure you covered all points listed in the following official documentation
https://cloud.google.com/container-registry/docs/advanced-authentication
This error occurs mostly due to docker config update, which you can check using command cat .docker/config.json
Now update with gcr with following command
gcloud auth configure-docker
Just in case anyone else is banging their head against a wall my PIA VPN caused this behavior.
"unauthorized: You don't have the needed permissions to perform this operation, and you may have invalid credentials. To authenticate your request, follow the steps in: https://cloud.google.com/container-registry/docs/advanced-authentication"
Turn my VPN off and it works fine. Turn it back on and it breaks again.
This is the only way that worked for me. I found it in a kubernetes/kompose Github issue.
Remove the credsStore key in ~/.docker/config.json
This will force docker to write the auth into the json when you use docker login. You can't untick Securely store Docker logins in macOS keychain in the docker desktop any more -- and the current credStore is no longer macOS keychain, it's desktop.
gcloud auth login Auth with gcloud (just to be explicit)
gcloud auth print-access-token | docker login -u oauth2accesstoken --password-stdin https://eu.gcr.io
You should see this:
WARNING! Your password will be stored unencrypted in /Users/andrew/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded
Source: https://github.com/kubernetes/kompose/issues/1043#issuecomment-609019141
The fix is as follows: run gcloud auth login (the browser will open and allow you to authenticate) then run gcloud auth configure-docker and select Y - then redo push. It should work like charm.
I also have the same issue in the Linux environment. So I just set the Docker to run as a non-root user, (https://docs.docker.com/engine/install/linux-postinstall/#manage-docker-as-a-non-root-user), and it works.
In my case DOCKER_CONFIG env variable was defined with an invalid value (not pointing to a docker config json).
I had the same issue, but for me, the problem was with internal users in my Linux system. I authenticated with gcloud my personal Linux user and when pushing, I was doing with root. So I had to authenticate my root user with gcloud as well:
sudo gcloud init
This issue happens to me when i switch service account which is pointing to different GCP Projects. Even though the service account has permission to push it says it does not have the permission. To resolve this by deleting config.json file which is present in .docker
Once this is done run the below commands and you should be able to push the image.
gcloud auth configure-docker
gcloud auth print-access-token | docker login -u oauth2accesstoken --password-stdin https://HOSTNAME
Where HOSTNAME= gcr.io , asia.gcr.io etc
Copy/pasting my username and password into the Docker Hub website works fine.
The password is long, but does not contain shell-breaking symbols.
Copy/pasting those same credentials into command-line docker login results in an incorrect username or password error. I have tried passing the credentials interactively (both copy/pasting and typing) and through command line args, same result:
# INTERACTIVE
$ docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username: my#email.com
Password: <REDACTED>
Error response from daemon: Get https://registry-1.docker.io/v2/: unauthorized: incorrect username or password
# COMMAND LINE
$ docker login -u my#email.com -p <REDACTED>
Error response from daemon: Get https://registry-1.docker.io/v2/: unauthorized: incorrect username or password
#mustaccio was correct.
The Docker Hub website allows you to login with either your username OR your email, and the website does not require a case-correct username.
docker login DOES require a case-correct username, and DOES NOT work with your email address.
When I signed up I chose a camel-cased username e.g.:
MyUsername
Docker forces this username to all lower case in practice. When you log in, you'll see your correct username in the upper right-hand corner of the website. In this example:
myusername
The website allows you to login with MyUsername or myusername.
docker login only allows myusername.
Same issue happens if you didn't logout and if you have put EMAIL address for login.
docker logout
docker login
DONOT PUT EMAIL ADDRESS, instead ENTER USERNAME
I used a password generator that put special characters in my password, I was able to login in my browser but not through the cli. I changed it to just letters and numbers and it worked.
Try this:
sudo chmod 666 /var/run/docker.sock
sudo docker login
I solved the problem by this way.
Go to https://hub.docker.com/settings/security and create a new token in my account.
To login use
docker login command
And type:
myusername in lowercase and
token (instead of password)
If You are using git bash on Windows then use following command:
winpty docker login --username <yourusername>
It will prompt for password. Enter your password. Message "Login Succeeded" displayed.
"yourusername" you can get on right top corner when logged in docker official site.
With your email it is not working.
If anyone is still experiencing this after ensuring your user and pass is correct, generate a token at account settings>security>new access token , I was struggling for an hour but using a token worked. Don't know why
On Windows:
Right click docker on the system tray and sign out. Then sign in but use your docker hub username not email address.
For logging into hub.docker.com, what worked for me was make sure you DO NOT specify 'hub.docker.com'!!! Different versions of API-DNS? All of this after I spent a good hour changing my password, changing my token, etc.
Just simply:
docker login --username=myusername <enter>
theToken <enter>
Adding special characters like # in password may mess-up login to docker from terminal , even if we use correct case and everything else correct . But it will work from website if we use a special char in password.
So basically use letters and number only in password , don't use special char for docker login
docker login
Do not use email id. Use your username in smallcase and then give password.
You should be successfully login.
please login with your DOCKER ID and password
this would work instantly
