This will be a POC for GKE.

Deploys ZoneMinder, a software-based network video recorder for live streams, using dlandon/zoneminder from DockerHub.

Uses Terraform to deploy a GKE Autopilot cluster.

Uses helm to deploy the ZoneMinder pod.

Developed on Ubuntu 18.04.

First run bash scripts/bootstrap.sh to install the needed tools

• gcloud (latest)
• helm (3.6.0)
• kubectl (latest)
• terraform (latest)

Now run gcloud init to authenticate & create a project. Copy down the project ID you're deploying to.

If you're using the GKE Free Tier, use the Project ID found in the console for the project that has the free tier credits

Set the parameters on your environment

TF_VAR_project_id is the GCP Project ID

TF_VAR_region is the region you're deploying to

ENV_NAME is the environment name for this deployment.

export TF_VAR_project_id=xyz-abc-12345678
export TF_VAR_region="us-central1"
export TF_VAR_env_name="zoneminder"

Create a service account to deploy the template: bash scripts/create-service-account.sh && mv gcloud.json terraform/

The GKE Cluster should be available after about 5 minutes.

cd terraform

Check that the template will deploy:

terraform init
terraform plan

Deploy when ready:

bash deploy.sh

cd ../

This should take about 6 minutes.

You may need to increase the limits in values.yaml as needed.

Make sure the environment variables you exported earlier are still available.

export init_delay_seconds=$(yq -r '.initialDelaySeconds' zoneminder/values.yaml)
helm install ${TF_VAR_env_name} zoneminder/ --values zoneminder/values.yaml --wait --timeout ${init_delay_seconds}s
external_ip=$(kubectl --namespace default get svc ${TF_VAR_env_name} -o json | jq -r '.status.loadBalancer.ingress[].ip')
echo "ZoneMinder should now be available at https://${external_ip}:8443/zm/"

At this point, ZoneMinder should be available & ready to go.

The ZoneMinder logs will indicate there were some events - Go ahead and clear these, they're leftover from the startup.

Make sure the environment variables you exported earlier are still available.

helm uninstall ${TF_VAR_env_name}

cd terraform/
terraform destroy -auto-approve
cd ../

bash scripts/destroy-service-account.sh

You can use ZoneMinder's FAQ to estimate your resource consumption.

The stack should cost about $33 USD per month, excluding traffic charges, with the default configuration.

By default, we request 1GB of RAM and .25 vCPU. The first GKE control plane is free, per the GKE free tier

We assume the deployment exists in us-central1

.25 vCPU @ 32.80/mo = 8.20/mo 1GB RAM @ 3.5934250/mo = 3.5934250/mo 1GB Ephemeral @ 0.0400040/mo = 0.0400040/mo

8.20 + 3.5934250 + 0.0400040 = 11.833429/mo

By default, we request 100Mi for the configuration PVC, and 10Gi for the data PVC, of type SSD. (Pricing Reference)[https://cloud.google.com/compute/disks-image-pricing#disk]

0.17/GB/Mo for SSD provisioned space

10.1 GB * 0.17/mo = 1.717/mo

We have two forwarding rules, one for 9000/tcp and one for 8443/tcp

The first 5 forwarding rules are a static 0.025/hr. This adds $18.25/month to the bill

Egress should be minimal, unless you're reviewing or downloading footage.

0.12/GB/mo for the first TB. I'll budget 10GB of data transfer per month. Is $1.20/month

11.83 + 18.25 + 1.717 + 1.20 ~= $33
