Image aliases must have a unique name, and ‘REF′isusedtwice.Useanothernamefor′REF' is used twice. Use another name for 'REF’.
Multiple CMD instructions were found. Only the last one will take effect.
COPY instructions cannot copy from its own alias. The ‘REF′aliasisusedbeforeswitchingtoanewimage.Ifyoumeanttoswitchtoanewimage,includeanew′FROM′statement.Otherwise,removethe′−−from=REF' alias is used before switching to a new image. If you meant to switch to a new image, include a new 'FROM' statement. Otherwise, remove the '--from=REF’ from the COPY statement.
