A systems administrator needs to create a Docker image from a Dockerfile located in the current directory. The image should include the tag 'webserver:v1'. Which of the following commands will successfully create the required Docker image?
The docker build command is used to build a Docker image from a Dockerfile. The -t option allows the user to specify a repository and tag in the 'name:tag' format for the image. Hence, docker build -t webserver:v1 . is the correct command, where '.' specifies the build context - in this case, the current directory containing the Dockerfile.
