What is the command for building an image in Dockerfile?

The command for building an image using a Dockerfile is “docker build”. By running this command in the terminal and specifying the path to the Dockerfile, Docker will create a new image based on the instructions in the Dockerfile. The specific command format is as follows:

docker build [OPTIONS] PATH | URL | -

OPTIONS are optional build options, PATH | URL | – specifies the path, URL, or standard input of the Dockerfile. For example, to build an image with the Dockerfile located in the current directory, you can run the following command:

docker build .

This will build the image using the Dockerfile located in the current directory.
