The problem is docker login creds take password directly in command option which is insecure. Commands get logged in event log for process creation or powershell or bash can be configured to log all of the script text. This can lead to creds getting leaked. So My question is how can i pass the secret to docker login without passing it directly in command line. I can't find any option in docker login that takes a file which has creds.
cat ~/my_password.txt | docker login --username foo --password-stdin
In one of the latest Teamcity you can create connection where you specify password (which is then invisible) and then using Build features you can use this connection to login before build process begins.

I am trying to write a bash script to automatize the setup of a multi-containers environment.
Each container is built from images pulled from a private protected repository.
The problem is that when the script calls for docker-compose up for the first time, access to the repository is denied, like if it does not know I have properly done docker login before running the script.
If I docker pull an image manually, that very image is no longer a problem when the script tries to build its container. But when it has to docker pull on its own from a Dockerfile definition, it gets access denied.
Considering that I would like this script to be portable to other devs' environments, how can I get it to be able to access the repository using the credentials each dev will have already set on its computer with docker login?
You can do something like:
#!/bin/bash
cat ~/pwd.txt | docker login <servername> -u <username> --password-stdin
docker pull
This reads the password from pwd.txt and logs in to the specified server.
In case you have multiple servers you want to log in you can try:
#!/bin/bash
serverlist="server1.com server2.com"
for server in $serverlist; do
cat ~/${server}_pwd.txt | docker login $server -u <username> --password-stdin
done
docker pull
This reads the passwords from files like server1.com_pwd.txt.
This is my .travis.yml
sudo: required
services:
- docker
....
....
# login to docker
- echo "$DOCKER_PASSWORD" | docker login -u "$DOCKER_ID" --password--stdin
- docker push <username>/<image-name>
Instead of using my Docker Hub password, I generated an Access Token at https://hub.docker.com/settings/security and set then up in Travis CI like so.
Travis CI Environment Variables
However, I get the following output in my build.
denied: requested access to the resource is denied
Turns out this is possible. Docker just re-uses the "password" mechanics for the access token, which seems misleading and inconsistent with similar types of tools.
From the Docker documentation:
At the password prompt, enter the personal access token.
For Travis CI specifically, specify your username via the DOCKER_USERNAME environment variable and your access token via the DOCKER_PASSWORD environment variable.
I would like to push a built docker image in the central docker hub in an automatic build process. To be able to do that, I need to login first before doing the push then.
The relevant section of the .gitlab-ci.yml file is the following:
docker-deploy:
image: docker:latest
stage: deploy
before_script:
- echo $HUB_PW | docker login -u $HUB_USER --password-stdin
after_script:
- docker logout
script:
- docker push <mytag>:$CI_PIPELINE_ID
I get the following error in Gitlab CI
$ echo $HUB_PW | docker login -u $HUB_USER --password-stdin
Error response from daemon: Get https://registry-1.docker.io/v2/: unauthorized: incorrect username or password
The relevant environment variables $HUB_PW and $HUB_USER are set correctly.
I have tried to do the same in a linux bash, with docker available, with the same result.
However, I am able to login into docker 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: <myusername>
Password:
Login Succeeded
When I do a logout, I get
docker logout
Removing login credentials for https://index.docker.io/v1/
There is no way to do an interactive login in an automatic build. And I don't understand the difference in the hubs URL, depending on using the interactive login and the one with the password included.
Has anyone any idea how to get this setup working?
I had similar problem because of $USERNAME contained $ character. By using the name with escape character directly in .gitlab-ci.yml for docker login
example: robot\$myname
gitlab connected to docker hub as expected.
Gitlab variables with $ in them can be escaped with a double dollar sign e.g. robot$$pusher.
\$ didn't work for me on enterprise edition 13.6.7-ee, but as far as I can tell double dollar escape syntax has been around since at least community edition 11.0.3

Created username password on hub.docker.com but I still get authentication error when I run docker run hello-world, and even when I run "docker login" then enter my credentials ....but it shows a success message when I do
docker login -u <myusername> -p <mypassword> https://hub.docker.com
but even after that if I try to run
docker run hello-world
I get the same error:
"error response from daemon: login attempt to https://registry-1.docker.io/v2/ failed with status: 401 Unauthorized"
Try logging out first with docker logout
I often find that this will at least allow me to pull images when there is some authentication issue.
docker logout
docker login
DONOT put email address as “username” when login from CLI. Instead USE username of you account
A few things going wrong here. First the login command shouldn't specify a url. Instead you specify a registry. And for hub, you don't even include that:
docker login -u <myusername> -p <mypassword>
Next, the hello-world image doesn't require any authentication. If you have bad credentials setup, you can logout:
docker logout
If you still see issues after that, the most likely cause is a proxy on your network intercepting the request, and it's not docker Hub giving the 401 error, but instead it's the proxy server. You can configure docker to use a proxy by following both of the following:
Configure the client: https://docs.docker.com/network/proxy/
Configure the engine: https://docs.docker.com/config/daemon/systemd/#httphttps-proxy
Try this command first:
docker logout https://hub.docker.com
You should get an output like:
Removing login credentials...
Then try to login.
I had similar problem, in my case, my solution was, that I need to input the password via STDIN method as below:
first create a file with the content is your docker password, e.g. in ~/my_password.txt
Then login using this method:
cat ~/my_password.txt | docker login --username [your_username_here] --password-stdin
Remember, your username is not your email.
Test docker login With modify Docker General Config (macOS High Sierra 10.13.3 & Docker Engine:18.09.2)
1. With GUI Account login
1.1 With General -> Securely store Docker logins in macOS keychain (checked)
docker login failed
1.2 With General -> Securely store Docker logins in macOS keychain (unchecked)
docker login successed
it will Authenticating with existing credentials.
2. With GUI Account logout
2.1 With General -> Securely store Docker logins in macOS keychain (checked)
docker login failed
2.2 With General -> Securely store Docker logins in macOS keychain (unchecked)

SO,
unchecked General->Securely store Docker logins in macOS keychain, it solved my docker login failed problem
Hi i'm trying docker push
[docker-simple-httpserver]# docker push myregistry/simplehttpserver:latest
The push refers to a repository [myregistry/simplehttpserver] (len: 1)
Sending image list
FATA[0000] Error: Status 403 trying to push repository simplehttpserver: "{\"error\": \"Unauthorized updating repository images\"}"
is there a way for me to specify the username and password on docker push command?
I would think they keep passwords off the command line for security reasons.
The way to do it is to login first then push.
https://docs.docker.com/mac/step_six/
$ docker login --username=maryatdocker --email=mary#docker.com
Password:
WARNING: login credentials saved in C:\Users\sven\.docker\config.json
Login Succeeded
Then push
$ docker push maryatdocker/docker-whale
The push refers to a repository [maryatdocker/docker-whale] (len: 1)
7d9495d03763: Image already exists
c81071adeeb5: Image successfully pushed
Typically you would specify your password using the interactive docker login then do a docker push.
For a non-interactive login, you can use the -u and -p flags:
docker login -u="${DOCKER_USERNAME}" -p="${DOCKER_PASSWORD}"
The Travis CI docs for docker builds gives an example of how to automate a docker login.
See docker login for more details.
As far as I know you have to use docker login. The credentials will be stored in /home/user/.docker/config.json for following docker pushes.
If you are after automation the command expect will be interesting for you.
In case, one needs to login to the custom docker repo, use below:
docker login -u ${USERNAME} -p ${PASSWORD} ${DOCKER_REPOSITORY}
The accepted answer works perfectly fine! However, if you are trying to access a private registry, you may have to consider making the following change request.
docker login -u ${user_name} ${private_registry_domain}
Provide password, when it prompt for the same.
docker login --username=YOUR_DOCKERHUB_USERNAME
In this case your dockerhub password will be an access token.
Refer: https://docs.docker.com/docker-hub/access-tokens/#create-an-access-token
If you are tagging image with IP then login docker registry with IP, If you are tagging image with domain-name then login docker with domain-name, Somehow docker doesn't like mixing IP and domain and failing.
Not direct answer to the question, but you can first login and then do docker push.
docker login -unice-username
After which it will prompt for a password. After successful login you can do docker push.
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded
use "sudo docker login" not "docker login" as one uses the root account and the other uses your personal.
Personally I create the repo on dockers website prior to the upload.
