Step into the magical world of GitOps, where version control meets holiday cheer! In this festive session, we'll embark on a journey guided by the enchanting melodies of a GitOps carol. Join us as we unwrap the secrets of Flux and Terraform Controller, the holiday heroes orchestrating infrastructure magic.

Discover how these tools harmonize with Git to bring joy and efficiency to your deployments. With live demonstrations, we'll showcase the dance of automation, ensuring your infrastructure stays in tune with the melody of your code. Learn how Flux and Terraform Controller make your deployments merrier, just in time for the most wonderful time of the year.

Let's sing a GitOps carol together and make this holiday season a symphony of smooth deployments and infrastructure delights. 🎶🎄✨

Deploying the resources

Step 1: Connect to Azure and set the context. Replace subscriptionID with the subscription identifier.

Connect-AzAccount

Set-AzContext <subscriptionID>

Step 2: Create the storage account for the Terraform state. Copy the storage account name.

./scripts/Create-StorageAccount.ps1

Step 3: Set the variables. Replace storage_account with the storage account name.

export STORAGE_ACCOUNT=<storage_account>

export APP="jingle"
export LOCATION="northeurope"
export ENVIRONMENT="production"
export RESOURCE_GROUP="rg-tfstate-jingle-neu"

export TF_VAR_app=${APP}
export TF_VAR_location=${LOCATION}
export TF_VAR_environment=${ENVIRONMENT}
export TF_VAR_resource_group=${RESOURCE_GROUP}
export TF_VAR_storage_account=${STORAGE_ACCOUNT}

Step 4: Initialize Terraform for each section.

cd terraform/shared && \
terraform init \
  -backend-config="storage_account_name=${STORAGE_ACCOUNT}" \
  -backend-config="resource_group_name=${RESOURCE_GROUP}" \
  -backend-config="key=${LOCATION}.tfstate"

cd ../environment && \
terraform init \
  -backend-config="storage_account_name=${STORAGE_ACCOUNT}" \
  -backend-config="resource_group_name=${RESOURCE_GROUP}" \
  -backend-config="key=${ENVIRONMENT}.${LOCATION}.tfstate"

Step 5: Deploy the resources for each section.

cd ../shared && \
terraform apply -auto-approve

cd ../environment && \
terraform apply -auto-approve

Step 6: Connect to the cluster.

Step 7: Install the Flux CLI.

brew install fluxcd/tap/flux

Step 8: Create a GitHub personal access token with the repo scope.

Step 9: Set the variable. Replace gh_token with the personal access token.

export GITHUB_TOKEN=<gh_token>

Step 10: Bootstrap Flux.

flux bootstrap github \
  --owner=smorenburg \
  --repository=jingle-ops-source \
  --branch=main \
  --path=clusters/production \
  --personal \
  --private=false

Destroying the resources

Step 1: Destroy the resources for each section.

cd terraform/environment && \
terraform destroy -auto-approve

cd ../shared && \
terraform destroy -auto-approve
