The Rancher v2.x Linux log collector script

This document (000020191) is provided subject to the disclaimer at the end of this document.

Situation

Rancher v2.x Linux log collector

Note:

This command requires curl or wget to be installed, and internet access from the node.

This script is intended to collect logs from Rancher Kubernetes Engine (RKE) CLI provisioned clusters, K3s clusters, RKE2 clusters, Rancher provisioned Custom, and Node Driver clusters.

This script may not collect all necessary information when run on nodes in Hosted Kubernetes Provider clusters.

Logs can be collected from a Linux node using the Rancher v2.x log collector script.

The script needs to be downloaded and run directly on the node, using the root user or sudo.

Output will be written to /tmp as a tar.gz archive named <hostname>-<date>.tar.gz, the default output directory can be changed with the -d flag.
