Helm real time logs Plugin

Overview:

rt-logs is a Helm plugin designed for CI/CD pipelines, enabling real-time log collection from Kubernetes resources without direct cluster access. It's tailored for scenarios requiring post-release log analysis in restricted-access environments.

Prerequisite

• Helm client with rt-logs plugin installed on the same system
• Access to the cluster(s) that Helm manages. This access is similar to kubectl access using kubeconfig files. The --kubeconfig, --kube-context and --namespace flags can be used to set the kubeconfig path, kube context and namespace context to override the environment configuration.

Install

Based on the version in plugin.yaml, release binary will be downloaded from GitHub:

$ helm plugin install https://github.com/noperformance/helm-rt-logs
Downloading and installing helm-rt-logs v0.1.0 ...
https://github.com/noperformance/helm-rt-logs/releases/download/v0.1.0/helm-rt-logs_0.1.0_darwin_amd64.tar.gz
Installed plugin: rt-logs

For Windows (using WSL)

Helm's plugin install hook system relies on /bin/sh, regardless of the operating system present. Windows users can work around this by using Helm under WSL.

$ wget https://get.helm.sh/helm-v3.0.0-linux-amd64.tar.gz
$ tar xzf helm-v3.0.0-linux-amd64.tar.gz
$ ./linux-amd64/helm plugin install https://github.com/noperformance/helm-rt-logs
