Knowledge sharing: Containers, Kubernetes, Openshift, F5 Container Connector, NGINX Ingress
For anyone interested about the free traning for "F5 Container Connector for Kubernetes" or "F5 OpenShift Container Integration" at "LearnF5". For NGINX being installed in Kubernetes there is enough info but for F5 Contaner Connector/Container Ingress Services there is not so much: https://docs.nginx.com/nginx-ingress-controller/f5-ingresslink/ https://www.nginx.com/products/nginx-ingress-controller/ https://community.f5.com/t5/technical-articles/better-together-f5-container-ingress-services-and-nginx-plus/ta-p/280471 F5 Devcentral also has youtube channel with usefull info: https://www.youtube.com/c/devcentral If you don't have good knowledge about containers and kubernetes then first check the links below. For Docker containers in youtube you will find a lot of good training for example: you need to learn Kubernetes RIGHT NOW!! - YouTube Docker Tutorial for Beginners [FULL COURSE in 3 Hours] - YouTube Docker overview | Docker Documentation The same is true for Kubernetes and they have a free test lab on their site: Learn Kubernetes Basics | Kubernetes you need to learn Docker RIGHT NOW!! // Docker Containers 101 - YouTube Red Hat has some free training and IBM provides some free labs for Containers, Kubernetes, Openshift etc.: Training and Certification (redhat.com) IBM CloudLabs: Free, Interactive Kubernetes Tutorials | IBM Red Hat OpenShift Tutorials | IBM
Issue with worker_connections limits in Nginx+
Hello Nginx Community, We are using Nginx+ for our Load Balancer and have encountered a problem where the current worker_connections limit is insufficient. I need our monitoring system to check the current value of worker_connections for each Nginx worker process to ensure that the active worker_connections are below the maximum allowed. The main issue is that I cannot determine the current number of connections for each Nginx worker process. In my test configuration, I set worker_connections to 28 (which is a small value used only for easily reproducing the issue). With 32 worker processes, the total capacity should be 32 * 28 = 896 connections. Using the /api/9/connections endpoint, we can see the total number of active connections: { "accepted": 2062055, "dropped": 4568, "active": 9, "idle": 28 } Despite the relatively low number of active connections, the log file continually reports that worker_connections are insufficient. Additionally, as of Nginx+ R30, there is an endpoint providing per-worker connection statistics (accepted, dropped, active, and idle connections, total and current requests). However, the reported values for active connections are much lower than 28: $ curl -s http://<some_ip>/api/9/workers | jq | grep active "active": 2, "active": 0, "active": 1, "active": 2, "active": 1, "active": 1, "active": 0, "active": 0, "active": 3, "active": 0, "active": 0, "active": 0, "active": 2, "active": 2, "active": 0, "active": 1, "active": 0, "active": 0, "active": 0, "active": 0, "active": 0, "active": 0, "active": 0, "active": 2, "active": 1, "active": 2, "active": 1, "active": 0, "active": 1, "active": 0, "active": 0, "active": 1, Could you please help us understand why the active connections are reported as lower than the limit, yet we receive logs indicating that worker_connections are not enough? Thank you for your assistance.
