MODWRKFLOW-66: Utilize relatively new Docker feature to change mode on COPY.#156
Merged
Conversation
…n COPY. This avoids relying on user space within the container to explicitly run `chmod`. This reduces the security burden if/when a `chmod` has some exploit and needs updating. This also reduces the extra duplication that Docker creates for every change. A separate `RUN chmod` command would result in a duplication of the entire JAR file and possibly other files within the image. Using `COPY --chmod=` avoids this. Be warned that this is a new feature and older **Docker** clients may have problems building this.
