docker image push does not work

[terrea]

I have created a new docker image with a

# docker build -t my-phpapache:7.4 .

Now, when I try to make

# docker image push

I'm logged in to a Docker hub in a browser. I see the errors:

$ docker image push --all-tags docker.io/library/my-phpapache
The push refers to repository [docker.io/library/my-phpapache]

To push, you need write access to the destination repository. With Docker Hub, those repositories must be under your userid, or in an organization where you have write access. The default path you see added, docker.io/library, is used by official images, which makes pulling official images easier. But since you aren't the author of docker official images, that won't work for pushing.

That means you need to:

docker build -t your-user/your-image:v1 .
docker push your-user/your-image:v1

Where your-user is the same user you used when running docker login.
