Hey so I'm working on spinning up a game server whereby a configmap defines one of the config files for it. And I have in the pod a second container that periodically checks for differences between the configmap-mounted file, and the file the game server is using. What I want to do is when the container checking periodically sees a difference (because I updated the configmap contents), copies the updated data over... I want it to trigger the pod as a whole to restart, which would logically result in the game server loading the updated config file (as it's on PV/PVC storage). What method would ..read more

Hey guys, I want to deploy my first backend application to a cloud environment (specifically gke) and I'm looking for resources to learn, I've been reading the gcp docs but I think I'm lacking some of the basics since it has been really difficult to grasp. For context I want to deploy a full model production application with a centralized authentication, possibly using an external idp such as keycloak, so my backend doesn't need to care about this details Does anyone have resource recommendations? Thanks! submitted by /u/RaphaS9 [visit reddit] [comments ..read more

Hi I have an EKS cluster with Nginx Ingress controller behind a Network Load Balancer, the TLS termination is at Ingress Controller (Nginx). The Network Load Balancer works in "ip" target mode. I also have AWS Load Balancer Controller installed and I see the configurations are propagated to the Network Load Balancer accordingly. I setup Nginx Ingress controller with the following Service annotations: ip internet-facing true "true" service.beta.kubernetes.io/aws-load-balancer-proxy-protocol: "*"service.beta.kubernetes.io/aws-load-balancer-nlb-target-type: ip internet-facing true "true" "*"se ..read more

Hey everyone, wondering what tools or approaches do you guys use for automatic remediation of common Kubernetes issues. Have been playing with Kured (for node remediation), Polaris, and we at Devtron has build Kubernetes Resource Watcher for remediating Kubernetes common issues like HPA Scaling MaX Out, OOM Killed, etc. Would love to hear if you did any POC around it, or have successfully implemented automatic remediation in your environments. What tools or process have you guys implemented?? submitted by /u/abhinavd26 [visit reddit] [comments ..read more

Hey there, I'm currently planning build some problem solving applications on top of Kubernetes. I had first planned to build a project for myself (but then decided to build something that solves a real problem). So what are the current problems faced by developers on Kubernetes? Also can they be solved by building an application on top of Kubernetes? Thanks for Suggestions!!! submitted by /u/Temporary_Ring4802 [visit reddit] [comments ..read more

In this podcast, I talked to Hannes Ullman from bifrost security, a probably still fairly unknown company with an amazing tool (or so I think). Bifrost builds some type of an application firewall (not only WAF) using AppArmor and profiles automatically created through training. Obviously supports Kubernetes ? I would be interested what you think about those tools? Only used WAFs before and found them a bit cumbersome (especially since most are cloud provider specific). If you're interested, you can find the episode (~25 minutes) on Youtube or an audio version (and links to Spotify and stuff ..read more

Hello all, I have nginx-ingress installed in my AWS cluster and so far nginx-ingress is "linked" with an AWS Network Load Balancer listening for TCP. This is the Helm values I use: controller: allowSnippetAnnotations: true service: annotations: service.beta.kubernetes.io/aws-load-balancer-type: elb service.beta.kubernetes.io/aws-load-balancer-name: ${lb_name} service.beta.kubernetes.io/aws-load-balancer-backend-protocol: tcp service.beta.kubernetes.io/aws-load-balancer-cross-zone-load-balancing-enabled: "true" service.beta.kubernetes.io/aws-load-balancer-scheme: internet-facing service.beta ..read more

I have noticed a strange networking performance issue on my cluster. It took some hunting but basicly if a call needs to go across nodes it gets about 500ms of aditional latency. The big tell for this is if you set up a nodeport service to a single pod, the node that pod is running on will not have the 500ms of aditonal latency. Stack is 3 node cluster + master 1.29.1 All nodes are running on the same VMware host on the same subnet Pod Network stack is Flanel 0.20.0 OS is ubuntu 22.04 Cluster was deployed with Kubeadm Flanel is a bit out of date but I know I saw this issue before my last flan ..read more
