First, credit is due. This is completely stolen from Greg ( (a.k.a. the wizard of everything).

Docker Inside Vagrant VM Using External Storage

Here is the scenario:

You are:

  • using Docker inside Vagrant-managed VM
  • using a Vagrant host computer with limited storage (e.g. MacBook Pro with SSD storage)
  • creating very large Docker images (>20Gb)

This creates an issue. Docker does not have enough space to store all your containers.

If you maintain an open-source Python package, you probably want to register it there since it makes the package distribution and installation very simple (easy_install <pckg> or pip install <pckg>).

Virtualenvs are essential to working with any package-dependent Python applications (which are all...). Virtualenvs are great however managing them and constantly doing source /vent_path/bin/activate becomes cumbersome very fast. To deal with some of the usability shortcomings of the virtualenv, the de facto solution is to use virtualenvwrapper. It adds many cool tricks to the developer toolbox and below are some of my favorites:

  • manages all virtualenvs within user ...
