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.
$ docker login --username=maryatdocker --email=
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)

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}
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.
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:
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
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.
