Docker: How to authenticate for docker push?

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?

Solution

  • 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 protected]
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)
