This repository was created solely to demonstrate existing problems and THE CODE IN IT SHOULD NOT BE USED FOR PRODUCTION PURPOSES:
The container assembly code is taken from the original repository: https://github.com/nginx/unit/blob/master/pkg/docker/Dockerfile.minimal
Changes and final goal:
The assembly commands are supplemented with the necessary commands to demonstrate the problem and find its subsequent solution.
To run a project with Docker installed on the computer:
- run the following command in the working folder of the project:
./test.sh; - view the current
STDOUTof theaaiu-testcontainer in the local Docker repository.
Docker "aaiu-test" containter STDOUT:
