podman-build:tldr:5dc24

The command "podman build --file ${Containerfile-different} ." is used to build a container image using Podman, a container engine alternative to Docker.

Here is a breakdown of the command:

• "podman build" is the main command that instructs Podman to build a new container image.

• "--file" specifies the path to the container file that contains instructions for building the image. In this case, the value is given as "${Containerfile-different}", which is a variable. The variable is not defined in this context, so it would typically be replaced with the actual path to the container file.

• The period (.) at the end of the command denotes the build context, which is the current directory. It tells Podman to build the image using the files and directories present in the current working directory.

In summary, this command uses Podman to build a container image using the instructions specified in the Containerfile at the path denoted by the variable "${Containerfile-different}". The build is performed using the files and directories in the current working directory.
