Static Pods are managed by kubelet on specific minion. As they are not associated with any controller, APIServer has no control over it. One of the use case for static pod might be for storage like gluster on each minion or maybe for os level debugging on OS like atomic host. For testing it, I referred kelseyhightower’s standalone kubelet guide. To install kubelet, we can either download kubelet binary and set it up manually or we can get it from kubernetes-node package,...

Example Use Cases When might you want to use a multi-stage build? It allows you to do an entire pipeline within a single build, rather than having to script the pipeline externally. Here’s a few examples… Java apps using WAR files First stage uses a container with Maven to compile, test, and build the war file Second stage copies the built war file into an image with the app server (Wildfly, Tomcat, Jetty, etc....

May times, We have to create demos for projects for which we use various desktop screen recorders along with normal earphones with mic for audio. But, It causes a lot of white/background noise in the video results into degraded video quality. Another case, where we record demos, talks from meetups. In this cases, we are not equipped with smart gadgets but only normal mic or mobile phone due to which lots of white noise occurs in a video....

It was beautiful Saturday morning and we were at yet another chapter of kubernetes Pune meetup. Meetup had a good turnaround of about 30 people, even it was the weekend. Harshal Shah started the Session on “Lifecycle of a Pod”, where he explained in detail about various states of pods, liveness and readiness probes as well as restart policies. That was really helpful as we get to know what actually happens to pod while deploying and undeploying the application....

I found some of them useful for me, so are they listed below. static check applies tons of static analysis checks. it needs go 1.6 or later, go get honnef.co/go/tools/cmd/staticcheck syntax is: $ statickcheck [pkg] or [directory] I tried it for kompose with some extra hacks: $ for pkg in $(go list -f '{{ join ....

Yesterday, I was working one of the Kompose issue, and I was working on map of string to struct, while iterating over a map I wanted to change elements of struct, so I tried similar to this, package main import "fmt" type Animal struct { count int } func main() { m := map[string]Animal{"cat": Animal{2}, "dog": Animal{3}, "mouse": Animal{5}} fmt.Println(m) m["dog"].count = 4 fmt.Println(m) } so I got this error,...
