How can I preinstall software on travis-ci?

We use travis-ci for continuous integration. I'm troubled by the fact that our build process takes too long (~30 minutes). We depend on several Ubuntu packages which we fetch using apt-get, among others python-pandas.

We also have some of our own debs which we fetch over HTTPS and dpkg install. Finally, we have several pip/pypi requirements, such as Django, Flask, Werkzeug, numpy, pycrypto, selenium.

It would be nice to be able to at least pre-package some of these requirements. Does travis support something like this? How can I prepackage some of these requirements? Is it possible to build a custom travis base VM and start the build from there (perhaps using docker)? Especially the apt-get requirements from the default Ubuntu precise repository as well as the pip requirements should be easy to include.

So while this question is already answered, it's doesn't actually provide a solution path. You can use cache directives in travis to cache your built packages for future travis runs.

cache:
  directories:
    - $HOME/.pip-cache/
    - $HOME/virtualenv/python2.7

install:
  - pip install -r requirements.txt --download-cache "$HOME/.pip-cache"

Now your package content is saved for your next travis build. You can similarly store slow-to-retrieve resources in other directories and cache them.

Currently Travis-CI doesn't support such a feature. There are related issues currently open though such as custom VMs, running Docker in an OpenVz container - (Spotify seems to have a somewhat working example links in this issue), using Linux Containers (LXC), using KVM.

Some of those have workarounds mentioned in the issues, I'd give those a try until something more substantial is supported by Travis-CI. I'd also suggest reaching out to Travis-CI support and see if they have any suggestions (maybe there's something coming out soon that could help).
