k8s-log-proxy

Simply HTTP interface for fetching Kubernetes pod/container logs.

It exposes a single HTTP GET endpoint /logs/<:namespace>/<:pod_name> under port 8080, which returns the most recent 8192 log lines from the specified pod.

Usage

Helm must be installed to use the chart. Please refer to Helm's documentation to get started.

Once Helm has been set up correctly, add the repo as follows:

helm repo add k8s-log-proxy https://adrianokf.github.io/k8s-log-proxy

If you had already added this repo earlier, run helm repo update to retrieve the latest versions of the packages. You can then run helm search repo k8s-log-proxy to see the charts.

To install the k8s-log-proxy chart:

helm install logproxy k8s-log-proxy/k8s-log-proxy

To uninstall the chart:

helm delete logproxy

Development

Skaffold

If you have access to a running Kubernetes cluster, you can use Skaffold for rapid development.

Skaffold handles the workflow for building, pushing and deploying the application, by simply invoking the following command in the root folder of the repository:

$ skaffold dev

The deploy/ folder contains all necessary Kubernetes resources for deployment, including a service account with appropriate role bindings to read all container logs.

Notes

This tool is a very quick solution, with no consideration of security or privacy concerns. Any user with access to the HTTP interface can access the logs of any pod in the cluster.

Proceed with caution!
