How to install Landscape Server with Juju

You can deploy Landscape in a scalable way with Juju. This document provides a very high-level overview.

For detailed instructions on deploying Landscape with Juju in a high-availability environment, see how to install and configure Landscape for high-availability deployments.

Install Juju

Install Juju as a snap with this command:

sudo snap install juju --classic

To learn more about Juju and to bootstrap a Juju controller, check out their getting started page.

Deploy self-hosted Landscape Server

When deploying with Juju, you will use a Juju bundle. A bundle is an encapsulation of all of the parts needed to deploy the required services as well as associated relations and configurations that the deployment requires.

landscape-scalable bundle

See also: Landscape-scalable bundle on Charmhub

In the landscape-scalable bundle configuration, each service gets its own machine. Currently that means you will need 4 machines for Landscape, and one for the controller node. Test it out using:

juju deploy landscape-scalable

For more detailed instructions on deploying the Landscape server with the bundle, refer to the Landscape Juju high availability installation guide.

Other bundles

The Landscape Scalable bundle is the only bundle currently supported. Previously, there were two additional bundles: landscape-dense and landscape-dense-maas. These bundles are now deprecated.

Access self-hosted Landscape

Once the deployment has finished, get the address of the first haproxy unit and access it with your browser:

juju status haproxy

Hi Yanisa,

I’m curious if it’s possible to add more units for the services in Juju deployment. Currently, each service is only scaled to one unit.

Is it possible to add units using the juju add-unit command? Alternatively, could I add units by modifying the Juju charm scripts that rebooting won’t erase the modification?

Additionally, is it possible to modify the hardware settings for each unit, such as increasing CPU cores or memory?

I would appreciate any advice you can offer. Thank you!

Hey @hillpig! I’m not quite sure on these questions - perhaps another community member can chime in and provide more insight? :slight_smile: You can also consider posting a new topic to the community on Landscape or Juju’s Discourse forums if you’re able.

  1. You can add units with juju add-unit. Here’s a link to Juju’s documentation for add-unit.
  2. I’m not sure if you can add units by modifying the Juju charm script. It might be possible, but I would expect using add-unit is more common for that.
  3. I think it’s possible to modify the hardware settings, but I’m not familiar with the Juju commands for that. Here’s a link to the Juju Docs. Their commands are well documented. (You might be looking for the command set-constraints?)
