Argo CD has become an essential deployment tool that engineers use to automate various infrastructure management use cases across hundreds of clusters. This presents a new challenge of managing Argo CD applications at scale. The Argo CD team has explored multiple approaches to solving this, resulting in the creation of ApplicationSet. Over time, ApplicationSet has gained many features, becoming sophisticated and quite complex to use. In this session, we will dive into advanced ApplicationSet features: orchestrating complex rollouts of ingress controllers across multiple clusters and accommodating snowflake clusters. We will enable the audience to answer these and many other questions about using ApplicationSet. Finally, we will demonstrate an effective way to debug ApplicationSet specifications without digging through logs and altering production Argo CD settings.
