.TH FENCE_AGENT 8 2009-10-20 "fence_gce (Fence Agent)" .SH NAME fence_gce - Fence agent for GCE (Google Cloud Engine) .SH DESCRIPTION .P fence_gce is an I/O Fencing agent for GCE (Google Cloud Engine). It uses the googleapiclient library to connect to GCE. googleapiclient can be configured with Google SDK CLI or by executing 'gcloud auth application-default login'. For instructions see: https://cloud.google.com/compute/docs/tutorials/python-guide .P fence_gce accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_gce can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
