Docker push - Send the image to the Docker Hub

Navigation
2

Alright?

Can anyone help me with the following problem?

First I logged in to Docker by running the command: 

$ docker login

It includes the registered user and password, however I'm having problems sending an image to the Docker Hub. When I run the following command: 

$ docker push projetofinal2_web

The following error occurs: 

The push refers to a repository [docker.io/library/projetofinal2_web]

I have verified that the image finalfile2_web actually exists using the command: 

$ docker images

Following the documentation : p>

  

To push a repository to the Docker Hub, you need to name your local image using your Docker Hub username, and the repository name that you created in the previous step [...]

You need to create a tag for the image before uploading:

  • build : $ docker build -t <hub-user>/<repo-name>[:<tag>] or
  • Image already created: $ docker tag <existing-image> <hub-user>/<repo-name>[:<tag>]

And then to upload to the remote repository: 

$ docker push <hub-user>/<repo-name>:<tag>

Where:

  • hub-user : your user in DockerHub
  • repo-name : the name of the remote repository in DockerHub
  • existing-image : image already built
  • tag : tag for the image (eg v1.0)

And for your case, you would do so, for example:

  • Add the tag in your image:

    $ docker tag projetofinal2_web:latest <seu_usuario_dockerhub>/<seu_repo_dockerhub>:v1.0

  • And then do the push :

    $ docker push <seu_usuario-dockerhub>/<seu_repo_dockerhub:v0.1
