travis-base-ubuntu-386.Dockerfile

# vim:ft=Dockerfile
# Same as travis-base.Dockerfile, but without the test suite dependencies since
# we only build Debian packages on Ubuntu i386, we don’t run the tests.

# NOTE: I tried exclusively using gce_debian_mirror.storage.googleapis.com
# instead of httpredir.debian.org, but the results (Fetched 123 MB in 36s (3357
# kB/s)) are not any better than httpredir.debian.org (Fetched 123 MB in 34s
# (3608 kB/s)). Hence, let’s stick with httpredir.debian.org (default) for now.
