Is there a fast way to comment out multiple lines in a Dockerfile?
I know that I can add # at the beginning of each line. But if there are many lines this is too much work. In some languages there are multiline comments such as /* ... */, which makes commenting out large parts of a file very fast.

Any modern IDE will allow you to select lines with mouse and do a simple control + / to comment all of them

Some community editions of JetBrains' IDE do not recognize Dockerfiles. To still be able to use the control + / shortcut, create a new file type, set "Line comment" to "#" and associate your Dockerfile with the newly created file type.

As of today, no.
According to Dockerfile reference documentation:
Docker treats lines that begin with # as a comment, unless the line is
a valid parser directive. A # marker anywhere else in a line is
treated as an argument.:
There is no further details on how to comment lines.
As said by some comments already, most IDE will allow you to perform multiline comments easily (such as CTRL + / on IntelliJ)
