Overview
Duration: 1:00
OpenStack is a very popular software stack for creating private and public clouds.
OpenStack is an advanced platform and deploying it manually may not be an easy task. Luckily, with conjure-up, it’s very simple and straightforward.
What you’ll learn
- How to install OpenStack on your machine with conjure-up
- How to install and configure LXD
What you’ll need
- A well-specced computer running Ubuntu 16.04 LTS with 16 gigabytes of RAM (SSD drive is strongly recommended)
- Some basic command-line knowledge
- An hour of your time

Installing and configuring LXD
Duration: 3:00
We’ll need to set up LXD to deploy OpenStack.
ⓘ LXD version
conjure-up requires that the minimum version of LXD be 2.18, so the version of LXD distributed through official repositories (which can be installed withsudo apt install lxd) is not compatible with conjure-up.
Installing LXD
The recommended LXD installation method is to use snaps. Don’t worry - the snap support is included with Ubuntu 16.04 LTS and above, so we don’t have to do anything.
To install LXD, open the terminal emulator and type:
sudo snap install lxd
Setting up LXD
Now, we have to initialize LXD. To do it, run the following:
sudo lxd init
We’ll be asked a few questions:
- Do you want to configure a new storage pool? - leave the default answer (“yes”)
- Name of the new storage pool - leave the default answer (“default”)
- Name of the storage backend to use - type “dir” (advanced users may choose another option)
- Would you like LXD to be available over the network? - leave the default answer (“no”)
- Would you like stale cached images to be updated automatically - leave the default answer (“yes”)
- Would you like to create a new network bridge? - leave the default answer (“yes”)
- What should the new bridge be called? - leave the default answer (“lxdbr0”)
- What IPv4 address should be used? - leave the default answer (“auto”)
- What IPv6 address should be used? - answer “none” (conjure-up doesn’t support IPv6)
Then, the following message should appear:
LXD has been successfully configured.
Now, we need to add ourselves to the “lxd” group. Execute the following commands:
sudo usermod -a -G lxd <username>
newgrp lxd
If you are using a proxy server, you might run into errors if you do not configure LXD specifically. To do so use the following commands:
lxc config set core.proxy_http <http proxy server>
lxc config set core.proxy_https <https proxy server>
lxc config set core.proxy_ignore_hosts <no_proxy hosts>
Installing OpenStack
Duration: 45:00
Now it’s time to install OpenStack. Firstly, install the conjure-up spell:
sudo snap install conjure-up --classic
Then, simply run:
conjure-up
We’ll see the “Spell selection” screen:
Choose “OpenStack with NovaLXD” and press Return.
Next, select “localhost” and again press Return:
On the next screen, leave the default values and click “Save”:
ⓘ Navigating inside conjure-up
To navigate between the main content and buttons located at the bottom of the screen, use Tab.
Then, leave the default SSH public key path and click “Next”:
After that, we’ll see the “Review and configure applications” screen. We can configure and deploy individual apps there. For the purpose of this tutorial we’ll deploy all of them, so choose “Deploy all 15 Remaining Applications”:
Now, the Juju controller will be initialized:
Then, the installation process will begin:
It may take several minutes for the deployment to finish. Please be patient.
Next, the post-deploy steps will be run:
Again, please be patient and wait for the post-deploy steps to finish.
After everything has completed, we’ll see the following screen:
Copy the Horizon URL to the clipboard or store it somewhere - we’ll need it in a while.
Checking if OpenStack is working
Duration: 1:00
Now, let’s check if everything is working.
Open a web browser and navigate to the Horizon using the URL we copied before. We will see the following login screen:
Use admin as a login and openstack as a password. After logging in, we should see something similar to this:
That’s all!

Congratulations, you have successfully installed OpenStack on your machine!
