What is the difference between a Docker Hub repository and image?

A Docker repository is where you can store 1 or more versions of a specific Docker image. An image can have 1 or more versions (tags). It’s also worth pointing out that the Docker Hub and other third party repository hosting services are called “registries”. A registry stores a collection of repositories.

What is Docker image repository?

A container repository is a collection of related container images used to provide different versions of an application. An example of a container repository is a Docker Repository on Docker Hub, which dedicates a location to the storage and publication of Docker images labeled with different tags.

What is Docker image example?

An image is a combination of a file system and parameters. Let’s take an example of the following command in Docker. The run command is used to mention that we want to create an instance of an image, which is then called a container. Finally, “hello-world” represents the image from which the container is made.

What is container and container image?

A container image is an unchangeable, static file that includes executable code so it can run an isolated process on information technology (IT) infrastructure. The image shares the OS kernel of its host machine. A container image is compiled from file system layers built onto a parent or base image.

What is a image repository?

What does image repository mean?

@CharlieParker A repository is a vessel for multiple images. The image base name is the repository name. The image tag discriminates different “versions” of an image (and docker has no opinion what “version” should mean, versions can contain totally different images).

Can a docker repository have multiple images?

Repositories can contain multiple images, but Docker Hub defaults to pulling only one image (the latest) from a repository. You can pull all images from the repository if you add the -a or –all-tags option to your pull: docker pull -a python (or docker pull –all-tags python ; you may use either interchangeably).
