Multi Stage Docker Builds

  • Hi,

    I am trying to do a multi stage docker build as my current docker image is too large but it seems that it is not possible with my current dockerfile.
    I start with

    FROM arm64v8/ubuntu:latest as BUILDER

    and it is unable to pull the image from docker.

    I also tried just
    FROM arm64v8/ubuntu:latest
    then when i need to copy the compiled file over in the next part using -
    COPY --from=0
    (0 being the first build)
    and i am returned with an error stating the --from parameter doesnt exist in voxl-docker.

    Does voxl-docker support multi stage deployment and if so how would i go about it ? or any useful tips ?

    Best regards

    Some folks have used the SD Card, though it's really slow. The recommended approach would be to build it off target, compress it, then copy it over to target

    I didn't know Docker had this feature, so thanks for that tip!

    Docker built on VOXL is running at version 1.9.0 and from some articles I read it looks like multistage build started in 17.06 (

    So I don't believe this is supported.
