The guide describes how to create and build a Docker image from a Dockerfile.

To work with Docker images, install and configure Docker.

CLI

Create a file named Dockerfile on your device and add the below lines to it:
```
FROM ubuntu:latest
CMD echo "Hi, I'm inside"
```
The described Docker image is based on Ubuntu and will execute one simple command.
Assemble the Docker image. For <registry_ID>, use the ID you got when creating the registry.
```
docker build . \
  -t registry.yandexcloud.net/<registry_ID>/ubuntu:hello
```
The -t flag assigns a URL to the Docker image in this format: registry.yandexcloud.net/<registry_ID>/<Docker_image_name>:<tag>. You can build Docker images without any tag. In this case, the Docker CLI will provide the default label: latest.

Once these commands are executed, a Docker image will be created in your repository with the hello tag and the full address of the repository, which includes:

Cloud Registry address: registry.yandexcloud.net.
Your registry ID: <registry_ID>.
Name of your ubuntu repository.
