WAR[0009] ONBUILD is not supported for OCI image format, COPY will be ignored. Must use docker forma

[VictoriaSexmer1]

I already have a Containerfile to create a container image. The file includes the following instruction:

....

ONBUILD COPY src/ /var/www/html 

....

However, when I execute this instruction, I receive the following warning message:

WAR[0009] ONBUILD is not supported for OCI image format, COPY src/ /var/www/html/ will be ignored. Must use docker format.

I am unsure how to resolve this issue, as one of the requirements is to allow copying the child’s files and overwriting the parent’s files.

Could somebody please help me?"
