Buildind docker image:/bin/sh: 1: ./build: Permission denied

Hello all
i am building a docker image containing spark 2.0, but for some reason when i get to the last command
of the file i am getting this exception

emoving intermediate container a723f9c1fadb
Step 32 : WORKDIR /spark
—> Running in 2936d1e72af3
—> 429b0eb79cba
Removing intermediate container 2936d1e72af3
Step 33 : RUN chmod -R 700 /bin/sh

Removing intermediate container ab908293b5fa
Step 34 : RUN ./build mvn -Pyarn -Phadoop-2.4 -Dhadoop.version=2.4.0 -DskipTests clean package
—> Running in 8c2aa6d59842
/bin/sh: 1: ./build: Permission denied
The command ‘/bin/sh -c ./build mvn -Pyarn -Phadoop-2.4 -Dhadoop.version=2.4.0 -DskipTests clean package’ returned a non-zero code: 126

Which is bizarre to me as

  • i am running as root
  • in the previous statement i did a chmod 700 to /bin/sh

Could anyone advise on what might be wrong?
pls find at the end of this file the last 10 lines of my docker image

kind regards
marco
