Mongodb-k8s Terraform Module

This mongodb-k8s Terraform module aims to deploy the mongodb-k8s charm via Terraform.

Getting Started

Install requirements

The following software and tools needs to be installed and should be running in the local environment.

• microk8s
• juju 3.x
• terrafom

Install Microk8s and enable storage add-on:

sudo snap install microk8s --channel=1.27-strict/stable
sudo usermod -a -G snap_microk8s $USER
newgrp snap_microk8s
sudo microk8s enable hostpath-storage

Install Juju:

sudo snap install juju --channel=3.1/stable

Install Terraform:

sudo snap install --classic terraform

Bootstrap the Juju using Microk8s and create a model to deploy Terraform module

Bootstrap Juju Controller:

juju bootstrap microk8s

Add Juju model named test:

juju add model test

Deploy Mongodb-k8s using Terraform

Initialise the provider:

terraform init

Customize the configuration inputs under terraform.tfvars file according to requirement. Make sure that given model-name exists.

Sample contents of terraform.tfvars file:

model_name  ="test"

Run Terraform Plan by providing var-file:

terraform plan -var-file="terraform.tfvars" 

Deploy the resources, skip the approval

terraform apply -auto-approve 

Check the Output

Run juju switch <juju model> to switch to the target Juju model and observe the status of the application.

juju status

The output should be similar to the following:
