FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8)

NAME

fence_docker - Fence agent for Docker

DESCRIPTION

fence_docker is I/O fencing agent which can be used with the Docker Engine containers. You can use this fence-agent without any authentication, or you can use TLS authentication (use --ssl option, more info about TLS authentication in docker: http://docs.docker.com/examples/https/).

fence_docker accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_docker can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.

Vendor URL: www.docker.io

PARAMETERS

Fencing action (Default Value: reboot)
IP address or hostname of fencing device This parameter is always required.
TCP/UDP port to use for connection with device (Default Value: 80)
Method to fence (onoff|cycle) (Default Value: onoff)
Physical plug number on device, UUID or identification of machine This parameter is always required.
Use SSL connection with verifying certificate
Use SSL connection without verifying certificate
Use SSL connection with verifying certificate
Version of Docker Remote API (default: 1.11) (Default Value: 1.11)
Path to CA certificate (PEM format) for TLS authentication. Required if --ssl option is used.
Path to client certificate (PEM format) for TLS authentication. Required if --ssl option is used.
Path to client key (PEM format) for TLS authentication. Required if --ssl option is used.
Disable logging to stderr. Does not affect --verbose or --debug-file or logging to syslog.
Verbose mode. Multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity.
Level of debugging detail in output. Defaults to the number of --verbose flags specified on the command line, or to 1 if verbose=1 in a stonith device configuration (i.e., on stdin).
Write debug information to given file
Display version information and exit
Display help and exit
Separator for CSV created by 'list' operation (Default Value: ,)
Wait X seconds before fencing is started (Default Value: 0)
Disable timeout (true/false) (default: true when run from Pacemaker 2.0+)
Wait X seconds for cmd prompt after login (Default Value: 5)
Test X seconds for status change after ON/OFF (Default Value: 20)
Wait X seconds after issuing ON/OFF (Default Value: 0)
Wait X seconds for cmd prompt after issuing command (Default Value: 3)
Sleep X seconds between status calls during a STONITH action (Default Value: 1)
Count of attempts to retry power on (Default Value: 1)
Path to gnutls-cli binary (Default Value: /usr/bin/gnutls-cli)

ACTIONS

Power on machine.
Power off machine.
Reboot machine.
This returns the status of the plug/virtual machine.
List available plugs with aliases/virtual machines if there is support for more then one device. Returns N/A otherwise.
List available plugs with aliases/virtual machines and their power state if it can be obtained without additional commands.
Check the health of fence device
Display the XML metadata describing this resource.

The operational behavior of this is not known.
Validate if all required parameters are entered.
