Docker "Unknown flag"

[jacopo-chevallard]

Hi, I'm getting a Docker error

Step 5 : FROM scratch
 ---> 
Step 6 : COPY --from=0 /container.beagle/ /
Unknown flag: from

when running this build https://app.shippable.com/github/jacopo-chevallard/BEAGLE/runs/263/1/console, and I was getting an error also when using the

FROM foo as bar

syntax. I tried to update Docker within the container that I boot, but apparently this is not the right way to have an updated Docker version (#4468).

If I run inside my build_ci section

docker --version
Docker version 1.9.1, build a34a1d5

Is this the expected available version? Am I missing something? thanks !

The runtime version your build is running on is a deprecated version. Please go to https://app.shippable.com/subs/github/jacopo-chevallard/nodePools > Click on Edit. In the Runtime Version section, you should be able to update the runtime version of your node pool to a newer version, which have the newer docker releases installed on the on-demand node brought up to run your builds.

Thanks so much for the super quick answer ! I didn't know users were responsible for manually updating the node version, but I guess this is necessary to prevent breaking build with automatic updates ! I'm re-running the build, I will then update here

Updating the node version solved the problem, closing
