Deploy MongoDB
Deploying a Charmed MongoDB K8s replica set is a quite straightforward operation with Juju. In this page, you will learn how to deploy and track the charm’s status as Juju sets it up in the background.
Summary
Deploy a replica set
Deploy MongoDB with the following command:
juju deploy mongodb-k8s --trust
The
--trustflag is necessary to grant the application access to the Kubernetes cluster
Juju will fetch the charm from Charmhub and begin deploying it to the MicroK8s cloud. This process can take several minutes depending on how provisioned (RAM, CPU, etc) your machine is.
Track deployment status
You can check the status of your deployment by running:
juju status --watch 1s --relations
This will display a table with an overview of all the status info of the elements in your juju model, like IP addresses, ports, state, and other useful data. The --watch 1s flag means that it will update every 1s.
For this tutorial, it is recommended to have a separate terminal permanently set to juju status --watch 1s --relations so that you can see what is happening every time you make changes to your juju model. The --relations flag will display additional information regarding integrations (previously known as “relations”), which will be useful later on.
When your MongoDB application is ready, juju status --watch 1s will show something similar to sample output below:
Model Controller Cloud/Region Version SLA Timestamp
tutorial overlord microk8s/localhost 3.1.6 unsupported 15:33:40Z
App Version Status Scale Charm Channel Rev Address Exposed Message
mongodb-k8s active 1 mongodb-k8s 6/stable 81 10.152.183.20 no
Unit Workload Agent Address Ports Message
mongodb-k8s/0* active idle 10.1.42.137
To exit the screen with
juju status --watch 1s, enterCtrl + C.
