When you work in a team, the Dockerfile needs to be shared the same way as the project code. Once the image is ready, the next step is publishing it to Docker Hub so it can be reused, deployed, and integrated with other environments.
The idea is straightforward: create an account, create a repository, build the image locally, tag it and push it. From there, the container can be reused in other projects and in CI/CD pipelines.
The process starts with creating an account on Docker Hub and the repository that will hold the name of the image. Then you run the build command with the desired tag, verify that the image was generated correctly and log in to Docker Hub from the terminal.
With the login done, the image receives a specific tag, such as a release version or simply latest. Then the push command sends the image to the remote repository, where it becomes available for download in any environment that has access to the registry.
In short, the flow is: create account → create repository → build image → docker login → docker tag → docker push. That turns the image into a shareable and reusable artifact without relying on manual file copying or Dockerfile variations between projects.
