The Juju UI team has been hard at work making it even easier for you to get started with Juju. We’ve got a new tool for everyone that is appropriately named Juju Quickstart and when you combine it with the power of Juju bundles you’re in for something special.
Quickstart is a Juju plugin that aims to help you get up and running with Juju faster than any set of commands you can copy and paste. First, to use Quickstart you need to install it. If you’re on the upcoming Ubuntu Trusty release it’s already there for you. If you’re on an older version of Ubuntu you need to get the Juju stable ppa
sudo add-apt-repository ppa:juju/stable
sudo apt-get update
Installing Quickstart is then just:
sudo apt-get install juju-quickstart
Once you’ve got Quickstart installed you are ready to use it to deploy Juju environments. Just run it with `juju-quickstart`. Quickstart will then open a window to help walk you through setting up your first cloud environment using Juju.
Quickstart can help you configure and setup clouds using LXC (for local environments), OpenStack (which is used for HP Cloud), Windows Azure, and Amazon EC2. It knows what configuration data is required for each cloud provider and provides hints on where to find the information you’ll need.
Once you’ve configured your cloud provider, Quickstart will bootstrap a Juju environment on it for you. This takes a while on live clouds as this is bringing up instances.
Quickstart does a couple of things to make the environment nicer than your typical bootstrap. First, it will automatically install the Juju GUI for you. It does this on the first machine brought up in the environment so that it’s co-located, which means it comes up much faster and does not incur the cost of a separate machine. Once the GUI is up and running, Quickstart will automatically launch your browser and log you into the GUI. This saves you from having to copy and paste your admin secret to log in.
If you would like to setup additional environments you can re-launch Quickstart at any time. Use juju-quickstart -i to get back to the guided setup.
Once the environment is up Quickstart still helps you out by providing a shortcut to get back to the Juju GUI running. It will auto launch your browser, find the right IP address of the GUI, and auto log you in. Come back the next day and Quickstart is still the fastest way to get back into your environment.
Finally, Quickstart works great with the new Juju charm bundles feature. A bundle is a set of services with a specific configuration and their corresponding relations that can be deployed together via a single step. Instead of deploying a single service, they can be used to deploy an entire workload, with working relations and configuration. The use of bundles allows for easy repeatability and for sharing of complex, multi-service deployments. Quickstart can accept a bundle and will deploy that bundle for you. If the environment is not bootstrapped it will bring up the environment, install the GUI, and then deploy the bundle.
For instance, here is the one command needed to deploy a bundle that we’ve created and shared:
If the environment is already bootstrapped and running then Quickstart will just deploy the bundle. The two features together work great for testing repeatable deployments. What’s great is that the power of Juju means you can test this deployment on multiple clouds effortlessly. For instance you can design and configure your bundle locally via LXC and, when satisfied, deploy it to a real environment, simply by changing the environment command-line option when launching Quickstart.
Try out Quickstart and bundles and let us know what you think. Feel free to hop into our irc channel #juju on Freenode if you’ve got any questions. We’re happy to help.
