Question

How do you create a Docker image from a Dockerfile in the current directory, naming the image 'myimage:v1'?

A) docker build -t myimage:v1 .
B) docker create -t myimage:v1 .
C) docker image create -t myimage:v1 .
D) docker build -i myimage:v1 .

Answer 1

To create a Docker image named 'myimage:v1' from a Dockerfile, the correct command is 'docker build -t myimage:v1 .', where 'docker build' initiates the build process, '-t' tags the image, and the '.' points to the current directory.

Step-by-step explanation:

To create a Docker image from a Dockerfile in the current directory and name the image 'myimage:v1', you would use the command:

A) docker build -t myimage:v1 .

This command utilizes the docker build command with the -t flag to tag the image with the name 'myimage' and version 'v1'. The period at the end of the command specifies that Docker should look for the Dockerfile in the current directory to build the image.
