Installing the whole development toolchain for Colour roughly means deploying:
... and too many things I just don't remember!
I decided to see how I could make that setup a bit more portable and easier to deploy.
The following guide assume that you have that you have PyCharm installed and are using macOS, although it should pretty much be platform agnostic.
Development Workspace Creation
On your local filesystem, in your development workspace, create a directory
Clone the colour-vagrant repository:
You should now have a
colour-vagrantdirectory nested into the
Let's open the
colour-vagrantdirectory into PyCharm.
We will loosely follow Jetbrain's PyCharm Documentation.
Install Fabric, this is the provider needed for the colour-vagrant environment. Initially, I was provisioning with Puppet. It was cumbersome to use, so I decided to go for Fabric and the vagrant-fabric plugin:
VirtualBox directories syncing performance degrades quickly with large number of files.
As a result the directories syncing is done with NFS.
You will however be asked for your macOS password at each virtual machine spin up because Vagrant needs to modify configuration files on the macOS host.
In order to avoid that and following the Vagrant Documentation, you can edit your macOS
/etc/sudoersfile and append the following content:
Cmnd_Alias VAGRANT_EXPORTS_ADD = /usr/bin/tee -a /etc/exports Cmnd_Alias VAGRANT_NFSD = /sbin/nfsd restart Cmnd_Alias VAGRANT_EXPORTS_REMOVE = /usr/bin/sed -E -e /*/ d -ibak /etc/exports %admin ALL=(root) NOPASSWD: VAGRANT_EXPORTS_ADD, VAGRANT_NFSD, VAGRANT_EXPORTS_REMOVE
PyCharm Vagrant Configuration
The canonical way is to use Vagrant from the command line as described in Vagrant Documentation, but here we will leverage the PyCharm integration.
Vagrant Executablefield to your Vagrant executable, e.g.
/usr/local/bin/vagrant. This should not be required as
vagrantshould be enough, but I encountered issues lately.
Instance Folderfield to your
Your configuration screen should be approximately as follows:
With everything setup, hit the
PyCharm --> Tools --> Vagrant --> Up
menu item to spin up the virtual machine.
You can go grab a coffee, the initial provisioning will take roughly 25-30 minutes.
If the provisioning ended smoothly, you should have the following elements available:
colour, colour-notebooks and colour-science.org repositories cloned into the
colour-sciencedirectory right next to the
Remote Python environments installed into the virtual machine at the following location with all the dependencies needed:
$ cd /home/vagrant/miniconda/envs/ $ ls -l total 16 drwxrwxr-x 4 vagrant vagrant 4096 Apr 29 03:12 ./ drwxrwxr-x 13 vagrant vagrant 4096 Apr 29 03:02 ../ drwxrwxr-x 20 vagrant vagrant 4096 Apr 29 03:09 python2.7/ drwxrwxr-x 20 vagrant vagrant 4096 Apr 29 03:30 python3.5/
The colour-science.org website served from the virtual machine at the following address: http://localhost:8080/
PyCharm Environment Configuration
Add the paths mappings from the macOS host to the virtual machine in the
Defaultsconfigurations, in my case the mappings are as follows:
/Users/KelSolaar/Documents/Development/colour-science = /colour-science
Your Run/Debug configuration screen should be approximately looking like that:
SSH Connection & Display
Accessing the virtual machine is done by using
PyCharm --> Tools Start SSH session... menu item.
However if you want to be able to export the display and see the figures you
will have to manually
ssh into the virtual machine:
You will also need to add the virtual machine to the X11 hosts by issuing the following command on the macOS host:
The Jupyter Notebooks server is started as follows:
Then you can access it on the macOS host at the following url: http://localhost:8888/
