The text discusses the challenges and solutions for utilizing Buildkite, a CI/CD tool, across various cloud platforms, particularly beyond AWS, where it is most seamlessly integrated. The author introduces the agent-stack-k8s, a method to deploy Buildkite agents using Kubernetes (k8s), which allows users to set up autoscaling CI/CD agents on any cloud platform, including Google Cloud Platform (GCP) and Azure, by leveraging Kubernetes clusters. The text guides users on setting up k8s clusters in multiple cloud environments, including AWS Elastic Kubernetes Service (EKS), Azure Kubernetes Service (AKS), and Google Kubernetes Engine (GKE), and provides insights into configuring these clusters with the necessary secrets and installing the Buildkite agent-stack-k8s using Helm charts. The author also emphasizes the importance of best practices such as version pinning and the use of specific queue tags for different workloads, while humorously advising readers to clean up their resources post-experimentation to avoid unnecessary cloud expenses.
