Hello everyone,

we have problems building docker images on Fiware instance. The problem is, that from within a docker container, we can't download any data from internet. Commands like wget, composer, apt-get don't work. Strangely ping to any live address works fine from within containers.

My Dockerfile starts like this:

FROM php:7.0.4-apache
RUN apt-get update && apt-get install -y zlib1g-dev libicu-dev g++
...
ADD entrypoint.sh /
RUN chmod +x /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]


but the build fails...

Same problems occurred when we uploaded existing container that works on different machines (Linode) to Fiware instance.

Internet connection from Instance itself works, just not from within a docker container.

Has anyone had the same issues with connectivity?

Thank you
