- 3-4 messages for Cornelias section: We continue to push the bar on PAS We bring k8s to PAS We are bringing proven capabilities to k8s (example of build service, and routing service We have been serving you in this build layer for the last 4-6 years Taking it to the next level with PAS 2.7 Taking what the industry has known about CI/CD and is upping the ante for CD (we’ve long conflated CI and CD) We’re exposing those in our flagship product The other thing we’re turning up the dial on is Kubernetes You know we built PAS on the best abstractions we had at the time (VMs, virtual storage… virtual networking was in it’s infancy) Now we have K8s, and that will let us deliver even greater outcomes PAS on K8s But that still for PAS, which is optimized for cloud-native workloads What are some capabilities in PAS and bringing those capabilities that over to k8s Last theme, implementation of those things that we bring over are a distributed system So how do you manage all of these services? We leverage k8s itself Most people know k8s as being really good at orchestrating containers… but that’s jsut the first implementation Beyond container scheduling being implemented on k8s… Beginning to be these examples in the community Build service and ingress service are examples of this.. K8s is fundamentally a platform for installing infinite loops… within that you can do whatever you want Example: k8s has a “replication set” and a controller that runs infinitely that checks how many you want and works when actual drifts… Routing tables also needs to be kept up to date… on an infinite loop, k8s can check if the number of routes in a routing table It’s an infitine loop that controls something other than containers Infinite loops are essential for distributed
- Native rolling application deployments Instead of requiring two apps and client orchestration, developers to perform this scenario natively with each app in PAS. API is GA; corresponding cli is beta Offers near-zero downtime push & restarts Launched as a beta in PAS 2.4 Previously exposed as cf v3-zdt-push cf v3-zdt-restart Now exposed via the v7 cli beta cf push --strategy rolling
- We’re also bringing PAS to Kubernetes. This is in alpha today. For PAS for Kubernetes, you can currently you can do cf push and cf log Alana Install Ops Manager on vSphere Deploy PKS tile Create a K8s cluster with PKS Configure pas-k8s to accept Eirini workloads Configure PAS for K8s tile Deploy PAS for K8s tile
