Doug Cutting commented on AVRO-1537:
------------------------------------
On Linux docker requires sudo.
With the current patch, trying 'sudo ./build.sh docker' on Ubuntu 14.04 fails
for me with:
{code}
Step 2 : RUN useradd -g 0 -u 0 -k /root -m root
---> Running in 761a21dcc7fb
useradd: user 'root' already exists
{code}
I fixed this by setting $USER to $SUDO_USER on Linux in build.sh:
{code}
if [ "$(uname -s)" == "Linux" ]; then
USER=${SUDO_USER}
...
{code}
Then everything works great for me.

> It's currently quite tedious to set up an environment in which the Avro test
> suites for all supported languages can be run, and in which release
> candidates can be built. This is especially so when we need to test against
> several different versions of a programming language or VM (e.g.
> JDK6/JDK7/JDK8, Ruby 1.8.7/1.9.3/2.0/2.1).
> Our shared Hudson server isn't an ideal solution, because it only runs tests
> on changes that are already committed, and maintenance of the server can't
> easily be shared across the community.
> I think a Docker image might be a good solution, since it could be set up by
> one person, shared with all Avro developers, and maintained by the community
> on an ongoing basis. But other VM solutions (Vagrant, for example?) might
> work just as well. Suggestions welcome.
