We use Helm as a package manager to more easily install other tools on Kubernetes.. kail from the top answer is Linux and macOS only, but Stern also works on Windows.. When deploying anything you need to have good visibility to what’s going on and logs are a first view into the inner workings of your application.

However, there's still a place for tail where you need to quickly debug something or perhaps you don't have persistent logging set up yet (such as when developing an app in Minikube). Stern is open source and available on GitHub, we'd love your contributions or ideas. stern envvars --context staging --container gateway Tail the staging namespace excluding logs from istio-proxy container. stern ". Awesome K8s Resources. 513. stern -n staging --exclude-container istio-proxy . They're very similar to the ones built into kubectl so if you're familiar with that you should feel right at home. On minikube ; Install stern . Author: Richard Li (Datawire) Kubernetes makes it easy to deploy applications that consist of many microservices, but one of the key challenges with this type of architecture is dynamically routing ingress traffic to each of these services. There are a number of reasons why I prefer Stern over Kail: The output coloring is much better; You can easily format the output (read: remove the stuff you don't want to see) It shows the names of the pods which are stopped and the ones which are starting; In my case, I'm for example only interested in seeing the pod name: For internal services we can talk directly to the gRPC endpoint while our website communicates using standard REST to the gateway. Tail the gateway container running inside of the envvars pod on staging, Show auth activity from 15min ago with timestamps, Follow the development of some-new-feature in minikube. api_server = 'https://kubernetes.example.com:8443' If the Kubernetes apiserver is using a self-signed SSL certificate, specify the CA certificate to verify against: However, normally when people talk about either Kubernetes or K8s, they are talking about the original upstream project, designed as a really highly available and hugely scalable platform by Google. Let's say we have a pod called service with 3 replicas. *" --tail 0 … To follow ALL pods without printing any prior logs from the default namespace you would run e.g.:. There was a hint of a smile on his usually rather stern face. When deploying anything you need to have good visibility to what’s going on and logs are a first view into the inner workings of your application.

However, I'd like to show an example above for a similar solution of printing since a certain time.

Editor’s note: today’s post is by Antti Kupila, Software Engineer, at Wercker, about building a tool to tail multiple pods and containers on Kubernetes. Some times people will join the Kubernetes community and get confused on what the “k8s” is all about. Allow DNS ; Create a test pod with curl ; Run minikube cluster ; Weave Net . Here's what that would look like: We're heavy users gRPC for internal services and expose the gRPC endpoints over REST using gRPC Gateway.
