Google Cloud Platform

Google Compute Engine

Just like other cloud providers Google allows for startup scripts. Once nice thing about GCE is you can easily restart your startup script for debugging reasons.

Login and run the following command to restart the startup script.

sudo google_metadata_script_runner --script-type startup --debug

This deployment will run Telegraf on Kubernetes. This will create a single pod configured to receive webhook events from configured repositories.

Dependencies:

• You must be running nginx ingress controller within your cluster.
• Your cluster should be running external dns with a configured domain and zone. This allows for DNS records to be created automatically.
• Certmanager should be used to handle creating TLS certificates.
• You should already or can create the required credentials for your Telegraf input and output endpoints.

Terraform + Github Actions

I struggled to get the right mix of github actions to lint my terraform modules within a monorepo. Here is the configuration I settled on which dynamically creates new jobs based on the data within the project.

I use a module naming pattern of provider-module_name, which becomes aws-kubernetes or gcp-gke. This information is important because the action executes the following command to create a list of modules.

$(printf '\"%s\"', gcp-* aws-* azure-* | sed 's/,$//')
