What are the steps after writing a Dockerfile when building a container?

After writing the Dockerfile, the main steps to build a container are:

1. Build the image — the docker build command reads the Dockerfile and executes instructions sequentially to create a container image.

docker build -t image_name .

   The dot `.` indicates the current directory where the Dockerfile is located.

2. **Run the container** — after successfully building the image, you can run a container based on this image:
   ```bash
docker run -d --name container_name image_name

3. Testing and debugging — verify that the container works as expected.

4. Publishing (optional) — you can upload the image to a remote registry (e.g., Docker Hub) for sharing:

docker push image_name

Thus, after writing the Dockerfile, you create an image, run a container, and if needed, distribute the image.
