I'm working on a Ubuntu Linux 20.04 Docker version is: Docker version 20.10.18, build b40c2f6
I have the following Dockerfile file

Then I run command:
docker build -t np1tshkodenko/api:8.1 .
I got the following output:

How can I fix this error to complete a build?
I've tried to execute docker build -t np1tshkodenko/api:8.1 . and I'm expecting to get a working container build.
You need to pass a value for the WWWGROUP variable when you build the image.
I don't know what a sensible value would be, but let's say that you want the value to be 'mygroup'. Then you'd do
docker build -t np1tshkodenko/api:8.1 --build-arg WWWGROUP=mygroup .
