Vespene Logo


Thanks for the interest in setting up Vespene!

To start, Vespene is a Python application. It is implemented using the Django web-framework on the frontend, and supervisord and python worker daemons on the backend. Both layers share a PostgreSQL database.

You will not need to know anything about Django to run the application, but if you do know Django, the following instructions should be a bit familiar to you.

If you don’t know Django, the provided shell scripts will automate nearly everything, and we’ll explain them as we go. Setup is supposed to be pretty easy - we’ve grown to dislike tools that take a long time to install, learn, and understand.

Some of your choices will come down to how you configure the plugins, but largely most Vespene installs should feel like any other Vespene install. That’s very important to us.

Vespene ships with a fair number of plugins, which will grow over time. We follow a “batteries included” approach to plugins, so as plugins are developed, you won’t have to hunt for what plugins work and don’t work, and their particular needs and requirements.

If you find the Vespene install instructions confusing or incomplete, please open a ticket on GitHub - it’s important to us that we make this go as smoothly as we possibly can, and suggestions to make this more understandable are very welcome.

Ready to start trying out Vespene?

You are encouraged to read the scripts before you run them (please do!), as they are very simple and short, and include some comments. As you read them, you’ll understand more about Vespene’s architecture and which files are important to it.

Vespene likes to put files in the following places:


If you like, you can skip our setup scripts and configure everything by hand (once you see what they do), or adapt them to use your favorite install automation - that is your choice. However, for the first time, we recommend trying the setup scripts.

Is My Platform Supported?

Vespene aims to be compatible with all Linux or Unix distributions.

The program already supports these, and where your favorite distros are not supported in the install scripts, we absolutely take patches to add them.

The setup scripts currently support:

  • Ubuntu Bionic Beaver (18.04)
  • Amazon Linux 2
  • CentOS 7 (using Software Collections)
  • Arch Linux
  • openSUSE
  • OS X (using Homebrew)

If you are unsure of what platform to use or do not have a preference, Ubuntu Bionic Beaver (for production or development) and OS X (for trying things out or development) are suggested.

All setup processes except OS X will run under the ‘vespene’ account, except OS X, which will run as the user who installed it. You can either use an existing PostgreSQL server or one of the install scripts can help you install a new one.

The only thing we clearly don’t run on yet is Windows. Windows worker support and automation will likely come in the possibly near future. If you are interested in working on Windows support, please let us know!

Once you have the app running in production mode, you may wish to know how to work on it as a developer.

For developer setup instructions, see Development Setup, which includes OS X developer tips. If you regularly develop on a Mac, skipping the install instructions and using the development instructions may be something you would like to do.

Where To Run What

The simplest possible Vespene installation uses one machine, running the web application, one or more worker processes, and the database. This is what you should start with as you explore Vespene for the first time.

The configuration for a larger installation is exactly the same - just run the same steps everywhere, possibly only changing the worker configuration from box to box - you can run multiple web nodes and multiple worker boxes, without any special effort. You of course will also only install one database, and then configure the workers to connect to that database using the Python settings files.

The workers communicate through a common database using lightweight database polling to avoid an extra message bus dependency (for now, anyway), so as long as they have the same database configuration, life is good. This means there isn’t an extra message bus or leader election system to keep up with.

You would run the setup scripts on each node in the soon-to-be Vespene cluster.


We’ll start by checking out Vespene into a temporary directory:

git clone ./vespene
cd ./vespene/setup

If your Linux/Unix operating system isn’t in the list of example installation scripts, you can probably read the setup scripts and adapt instructions accordingly without too much trouble.

Common Settings

We need to adjust some settings. If you read through there are explanations of a lot of choices to make, which result in configurations (ultimately) in /etc/vespene. If you ignore most of this file, be positive you pick a unique database password and don’t just use the default, but the other settings are pretty good starting choices:

$ vim

Note the database address you chose in this file. If you plan to use an external database, name that hostname now, and keep that in mind when you get to the database setup step a bit later on. Otherwise, you’ll install it as part of this setup process. You could also choose to use an external database, such as PostgreSQL on Amazon RDS.

The configuration you are editing now is just for the quick setup script, normally Vespene configuration lives in /etc/vespene. These setup scripts will be configuring some settings in /etc/vespene with your choices.

There are some defaults that ship with the application (like Plugins) that are completely skipped by this setup process, and you’ll want to read up on those later once you have things working. You’ll get Vespene with a minimal plugin configuration that should work for learning the tool, but that you might want to customize later.

Unless you wish to re-run these scripts, you won’t be editing this setup script again.

Software Dependency Setup

It’s time to install some dependencies.

This step will install Python 3 (if needed) and then install Python dependencies.

Once installed, Vespene will reside in /opt/vespene and settings will be in /etc/vespene/.

Run the requirements setup script as follows:

$ bash

Run these under a user account that has sudo access, as the install scripts will invoke sudo.

Database Setup

We’ve mentioned this already when talking about settings, but decide where you want to run the Vespene database.

In the simplest possible configuration where you have only one machine running Vespene to start, installing a database on this server is quite reasonable.

To run the script to install the database:

$ bash

If you are intending to deploy a multi-node environment, setup is on your own, just make a database available at the server address and username/password you selected in “Step 0”.

Application Setup

This next step will configure the application to point at the Vespene database and run any database migrations that may be required during an upgrade:

$ bash

This step will have generated some secrets in /etc/vespene/settings.d/ IMPORTANT: If you are performing a multi-site install, you will need to copy this file to all machines in the Vespene cluster prior to starting those nodes in step 6. In particular, secrets in this file are used to encrypt some data in the database and protect the Django installation against some hijinks. If these files are not consistent across the cluster, decoding of secrets (like logins and SSH keys) won’t work correctly. This is further explained in Security Guide.


Once and only once per cluster, you need to run the superuser configuration step:

$ bash

This will interactively prompt you for a username and password for the superuser account. This is the account you will use to to login to Vespene for the very first time, so remember what password you chose.

Creating Tutorial Objects

This step is optional.

Vespene is now mostly installed, but if you were to log in, there’s not a lot configured. We find that initially seeing a blank screen might not give users the best initial experience, so the next command will create some basic objects for learning Vespene:

$ bash

Service Configuration

The final step will configure the Vespene service to start automatically on boot, using a systemd unit file that starts a series of supervisor processes configured in /etc/vespene/supervisord.conf.

You will automatically get a copy of the webserver and also any worker processes configured in will also be added to the supervisor config.

$ bash

If you ever want to change how many worker processes run on each node (and which ones), you can just edit the common configuration and rerun this step on that particular node:

$ vi
$ bash

You could of course also edit the supervisor config directly in /etc/supervisord and then restart the “vespene.service” systemd service.

Once started, Vespene will serve the UI on port 8000, which should be enough for most production deployments. You could choose to proxy it with NGINX or Apache if you wanted, for instance to add an SSL cert.

You can also choose to use something other than supervisor to run the worker processes if you wish. Nothing in Vespene itself checks for these to be managed by supervisor, so if you start them some other way, that is acceptable.

One minor gotcha is that we didn’t know in advance if you wanted to install the database server on the same box as the Vespene services, so the Vespene services don’t normally have a startup dependency on the database. You can add this by editing the systemd unit file.

If the service is not operational on reboot because PostgreSQL was not ready, just restart “vespene.service” using “systemctl restart vespene.service”.

Developers can learn about starting workers and the web process in Development Setup and many systems administrators will also benefit from understanding this as well. In short, supervisord runs and watches over commands that are not far off from the development testing commands, and all systemd really does is launch supervisord.


Visit your webserver on “/” (port 8000) to see if everything is operational.

Login Prompt

Once ready, you can hop on over to the Tutorial.

Configuration Updates

As a reminder, all configuration resides in /etc/vespene/settings.d

After making any changes there, you will need to bounce the service:

systemctl restart vespene.service


Should you wish to study them, logs are all sent to /var/log/vespene/

Using Configuration Management Systems

If you would like to create Vespene content for your automation system rather than using these scripts, that’s fine. You should probably still take a look at these scripts for reference.

The nice thing about doing them in bash was that it’s easy for someone to understand regardless of what automation system they know.

Upgrades & Maintenance

You don’t have to do it now, but you should probably read Upgrades and CLI (for cleanup commands) before you get too far along. They talk about the update step for database migrations, backups, and managing clutter from build artifacts. In all, there’s not a lot of associated maintenance activity to worry about.

Thanks for trying out Vespene and have fun!
