Install Gaia - Terraform UI on GKE using Helm

#gaia #terraform

Gaia: A GUI tool that makes managing infrastructure more simple for Terraform.

Some of the features include Visual editor, dependency visualisation, administration of variables and modules, and simplified workflow.

Infrastructure described in YAML and translated into Terraform code.

Gaia Features :

• Improved User Experience: Terraform infrastructure administration is made simpler with Gaia's visual interface.
• Workflow Simplified: Gaia streamlines routine Terraform operations and eliminates the need for manual command execution.
• Dependency Visualization: Gaia's visual representation of resource dependences makes it easier to build and manage infrastructure.
• Simplified Module and Variable Management: The GUI of Gaia has built-in capabilities for managing modules and variables.
• Collaboration and Teamwork: Gaia enables teamwork by giving various team members working on infrastructure setups a single interface.
• Faster Onboarding: The graphical design of Gaia makes it easier for novice users to comprehend and use Terraform setups.
• Code consistency and validation: Gaia checks configurations in real time to make sure they comply to best precises for Terraform and to avoid mistakes.

Gaia Requirements:

• A docker daemon (for running Terraform)?
• A MongoDb database (for storing data)

Installation steps:

Enable APIs required for GKE -

devops@cloudshell:~ (poc-project101)$ gcloud services enable container.googleapis.com????????????????????????????????????????????????????????????????

Operation "operations/acf.p2-955994325641-b314bad1-a553-4314-8814-247792f58487" finished successfully.?        

Create a Single Node GKE using gcloud -

devops@cloudshell:~ (poc-project101)$ gcloud container clusters create gke-cluster --num-nodes=1 --zone=us-east1-c

Create namespace gaia -

devops@cloudshell:~ (poc-project101)$ kubectl create namespace gaia
namespace/gaia created
devops@cloudshell:~ (poc-project101)$?        

Install Gaia helm chart -

devops@cloudshell:~ (poc-project101)$ helm install gaia https://github.com/gaia-app/chart/archive/refs/tags/v0.1.2.tar.gz --namespace gaia
NAME: gaia
LAST DEPLOYED: Mon Jun 12 17:21:36 2023
NAMESPACE: gaia
STATUS: deployed
REVISION: 1
NOTES:
1. Get the application URL by running these commands:
? ? ?NOTE: It may take a few minutes for the LoadBalancer IP to be available.
? ? ? ? ? ?You can watch the status of by running 'kubectl get --namespace gaia svc -w gaia'
? export SERVICE_IP=$(kubectl get svc --namespace gaia gaia --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}")
? echo https://$SERVICE_IP:80
devops@cloudshell:~ (poc-project101)$        

List helm chart -

devops@cloudshell:~ (poc-project101)$ helm ls -n gaia
