2. Set up the environment¶
This is part of the Charmed Apache Kafka Tutorial. Please refer to this page for more information and an overview of the content.
Setup the environment¶
Multipass is a quick and easy way to launch virtual machines running Ubuntu. It uses “
Let’s install Multipass from Snap and launch a new VM using “
sudo snap install multipass && \
multipass launch --cpus 4 --memory 8G --disk 50G --name my-vm charm-dev
Note: See all multipass launch parameters in the launch command documentation.
Multipass list of commands is short and self-explanatory, e.g. show all running VMs:
multipass list
As soon as the new VM starts, enter:
multipass shell my-vm
Note: if at any point you’d like to leave Multipass VM, use Ctrl+D or type exit.
All the parts have been pre-installed inside VM already, like MicroK8s, LXD and Juju (the files /var/log/cloud-init.log and /var/log/cloud-init-output.log contain all low-level installation details).
Also, the image already comes with two Juju controllers already setup, one for LXD and one for MicroK8s
$ juju list-controllers
Use --refresh option with this command to see the latest information.
Controller Model User Access Cloud/Region Models Nodes HA Version
lxd* tutorial admin superuser localhost/localhost 2 1 none 3.1.5
microk8s - admin superuser microk8s/localhost 1 1 - 3.1.5
Make sure that you use the controller bound to the MicroK8s cluster, e.g.:
juju switch microk8s
The Juju controller can work with different models; models host applications such as Charmed Apache Kafka K8s. Set up a specific model for Charmed Apache Kafka K8s named tutorial:
juju add-model tutorial
You can now view the model you created above by entering the command juju status into the command line. You should see the following:
Model Controller Cloud/Region Version SLA Timestamp
tutorial microk8s microk8s/localhost 3.1.5 unsupported 15:46:55+02:00
Model "admin/tutorial" is empty.
