       - db_data:"C:\\repository\\docker\\wordpress\\data"
     restart: always      
     environment:

How to Solve Error Message failed to solve with frontend dockerfile.v0: failed to create LLB definition: the Dockerfile cannot be empty

This is the part for explaining how to solve error message. Actually, the solution is very simple and the information for solving the error message is also exist as part of it. In the error message, there is information which is hinting the solution. That part is in ‘the Dockerfile cannot be empty’. Well, it obvious since in the previous article in this link, the solution is just to create a file with the name of ‘Dockerfile’. So, continue on to get the solution for the problem, just add a line in the empty Dockerfile. In this case, the line is just one simple line for pulling an image from the public docker image repository. The following is the content of the file : 

FROM mysql:5.7

The above line is just enough to solve the problem handling the error message. But in the context for solving the previous article in this link, where it actually there is two services where each of them need a different image, just add another one as follows : 

FROM mysql:5.7
FROM wordpress

After finishing on editing the Dockerfile above, just run the ‘docker-compose build’ once more. If there is no further error appear, the docker will be available. Just list it by executing the following command : 

C:\repository\docker\wordpress\build>docker image list --all
REPOSITORY TAG    IMAGE ID     CREATED    SIZE
mysql      5.7    4fd19a131d40 3 days ago 609MB
wordpress  latest 4fd19a131d40 3 days ago 609MB

C:\repository\docker\wordpress\build>
