About the LogDNA Agent for Kubernetes and OpenShift

The LogDNA Agent for Kubernetes or Red Hat OpenShift is written in Rust, and uses the Linux kernel to monitor the log files and directories for changes, rather than having to poll these files constantly. This implementation frees up CPU utilization and improves stability.

Supported Platforms and OSes

For more information, refer to the LogDNA Agent Support Matrix.

• Kubernetes version 1.9 or later
• OpenShift version 4.5 or later

For more detailed information about the LogDNA Agent for Kubernetes and Openshift, refer to the documentation in our public GitHub repository.

Quick installation

For a quick installation, without cloning the GitHub repo, you can run three simple commands in your terminal to create a logdna-agent namespace with your ingestion key and then deploy the LogDNA Agent DaemonSet to your cluster.

kubectl apply -f https://assets.logdna.com/clients/agent-namespace.yaml
kubectl create secret generic logdna-agent-key -n logdna-agent --from-literal=logdna-agent-key=<your ingestion key> # this is your unique Ingestion Key
kubectl apply -f https://assets.logdna.com/clients/agent-resources.yaml
