docker: Build a docker image using the Dockerfile in the current directory.
$ docker build .
try on your machine
The command "docker build ." is used to build a Docker image from the Dockerfile present in the current directory.
Explanation of the command components:
- "docker build" is the command to instruct Docker to build an image.
- The dot (.) indicates the build context, which specifies the location of the Dockerfile and any files referenced inside it. In this case, it represents the current directory as the build context.
- The Dockerfile is a text file that contains instructions to build an image. It defines the dependencies, environment variables, and other configurations for creating the image.
When you execute the "docker build ." command, Docker searches for a Dockerfile in the current directory and uses it to create an image. Docker reads the instructions in the Dockerfile, downloads the necessary dependencies, and performs all the defined steps, such as copying files, running commands, or setting environment variables. Once the build process is complete, Docker produces a new image that can be used to run containers.

never run a command you are not sure if it is safe.
