Question

Once you've worked with an image, how do you push it to docker hub?

Answer 1

To push an image to Docker Hub, follow these steps: create a Docker Hub account, tag the image with your Docker Hub username and repository name, login to Docker Hub, and push the tagged image.

Step-by-step explanation:

To push an image to Docker Hub, you need to follow a few steps:

1. First, make sure you have a Docker Hub account. If you don't, create one.
2. Next, tag your image with the Docker Hub username and repository name, using the following command: docker tag <image> <username>/<repository>.
3. Then, login to Docker Hub using the command: docker login and provide your Docker Hub credentials.
4. Push the tagged image to Docker Hub using the command: docker push <username>/<repository>.

For example, if your Docker Hub username is 'johnsmith' and repository name is 'myapp', you would use the following commands:

docker tag myimage johnsmith/myapp

docker login

docker push johnsmith/myapp
