    Correctness

    alias-must-be-unique

    Image aliases must have a unique name, and ‘REF′isusedtwice.Useanothernamefor′REF' is used twice. Use another name for 'REF′isusedtwice.Useanothernamefor′REF’.

    multiple-cmd-instructions

    Multiple CMD instructions were found. Only the last one will take effect.

    copy-from-own-alias

    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′aliasisusedbeforeswitchingtoanewimage.Ifyoumeanttoswitchtoanewimage,includeanew′FROM′statement.Otherwise,removethe′−−from=REF’ from the COPY statement.
