Juju is a tool for deploying, configuring and operating complex software on public or private clouds. It can be installed with a snap:
sudo snap install juju --classicJuju has baked-in knowledge of many public clouds such as AWS, Azure and Google. You can see which ones are ready to use by running this command:
juju cloudsMost clouds require credentials so that the cloud knows which operations are authorised, so you will need to supply these for Juju. Other options are available here.
juju add-credential gcpThe Juju controller is used to manage the software deployed through Juju, from deployment to upgrades to day-two operations. One Juju controller can manage multiple projects or workspaces, which in Juju are known as ‘models’.
juju bootstrap gcp my-controllerThe model holds a specific deployment. It is a good idea to create a new one specifically for each deployment.
juju add-model k8sRemember that you can have multiple models on each controller, so you can deploy multiple Kubernetes clusters or other applications.
Deploy the Kubernetes bundle to the model. This will add instances to the model and deploy the required applications. This can take up to 20 minutes depending on your machine.
juju deploy charmed-kubernetesJuju is now busy creating instances, installing software and connecting the different parts of the cluster together, which can take several minutes. You can monitor what’s going on by running:
watch -c juju status --colorTo view the last twenty log messages for the “k8s” model:
juju debug-log -m k8s -n 20Congratulations! You have a Kubernetes cluster up and running - now let’s use it! The link below takes you to the operations guide, detailing some of the common things you’ll want to do next:
