The document discusses containerization and test automation practices at Trend Micro. It describes how the company uses containers, Kubernetes, and related tools to improve their continuous delivery processes. Key practices include using TestRail for test case management and automatically syncing test cases with a robot framework; implementing blue/green deployments in Kubernetes for faster, safer releases; leveraging Kubernetes features like configmaps, secrets, and ingress for configuration management and routing; and monitoring containerized services with Prometheus and Grafana. Testing is also containerized for easier replication of environments and parallel test execution.
