Keep in mind COPY and RUN command create same size of images layer twice. For this case if COPY created 118MB layer then RUN command will be created another same size of layer. It's means another 118MB layer will be added in your image. We should avoid COPY command rather we should use CURL inside RUN command to copy jar file from maven repository. That will reduce another 118MB from your image. Example: present image size => 105MB [FROM] + 118MB [COPY] + 118MB [RUN] => 340MB reduced image size => 105MB [FROM] + 0MB [COPY] + 119MB [RUN] => 224MB
