Línea de trabajo

Start by reading the attached minion TCP log and tracing the TCP transport reconnect behavior for the reported recon_default, recon_max, and master_tries settings. Reproduce the master outage with the reported configuration, then identify why the minion stops retrying. Done means the minion reconnects after the master returns without restarting the service; the issue names no source files or tests.

Descripción

bug needs-triage severity-high
What happened?

We are trying salt (tcp transport) with master in Kubernetes cluster in AWS environment:

  • single master is a namespace 1 pod deployment with TCP ingress route to the master
  • an internal Network Load balancer in front of the cluster

With 3008.3, when there is an outage of the master:

  • salt-minion stop trying to reconnect to the master
  • only after restarting salt-minion service, then connection is re-established.
