NAME

       ocf_heartbeat_varnish - Manage a Varnish instance

SYNOPSIS

       varnish [start | stop | status | monitor | meta-data | validate-all]

DESCRIPTION

       The Varnish Resource Agent can manage several varnishd instances
       throughout the cluster. It does so by creating a unique PID file and
       requires a unique listen address and name for each instance.

SUPPORTED PARAMETERS

       config
           The VCL configuration file that varnish should manage, for example
           "/etc/varnish/default.vcl".

           (unique, required, string, no default)

       name
           Override the name of the instance that should be given to varnish
           (defaults to the resource identifier).

           (unique, optional, string, default "default")

       pid
           Write the process's PID to the specified file. The default will
           include the specified name, ie.: "/var/run/varnish_production.pid".
           Unlike what this help message shows. It is most likely not
           necessary to change this parameter.

           (unique, optional, string, default "/var/run/varnishd_default.pid")

       listen_address
           Listen on this address:port, for example "192.168.1.1:80"

           (unique, optional, string, default "0.0.0.0:80")

       mgmt_address
           Provide a management interface, for example "127.0.0.1:2222"

           (unique, required, string, no default)

       ttl
           Specifies a hard minimum time to live for cached documents.

           (optional, integer, default 600)

       varnish_user
           Specifies the name of an unprivileged user to which the child
           process should switch before it starts accepting connections.

           (optional, string, default "varnish")

       varnish_group
           Specifies the name of an unprivileged group to which the child
           process should switch before it starts accepting connections.

           (optional, string, default "varnish")

       backend_type
           Use the specified storage backend. Valid options are 'malloc' for
           memory and 'file' for a file backend.

           (optional, string, default "malloc")

       backend_size
           Specify the size of the backend. For example "1G".

           (optional, string, default "1G")

       backend_file
           Specify the backend filename if you use backend_type file. For
           example /var/lib/varnish/mybackend.bin

           (unique, optional, string, default "/var/lib/varnish/default.bin")

       worker_threads
           Start at least min but no more than max worker threads with the
           specified idle timeout.

           Syntax: min[,max[,timeout]] For example: 100,3000,120

           (optional, string, default "100,3000,120")

       client_binary
           This is used to control varnish via a CLI. It's currently only used
           to check the status of the running child process.

           (optional, string, default "varnishadm")

SUPPORTED ACTIONS

       This resource agent supports the following actions (operations):

       start
           Starts the resource. Suggested minimum timeout: 20.

       stop
           Stops the resource. Suggested minimum timeout: 20.

       monitor
           Performs a detailed status check. Suggested minimum timeout: 20.
           Suggested interval: 10.

       status
           Performs a status check. Suggested minimum timeout: 20.

       meta-data
           Retrieves resource agent metadata (internal use only). Suggested
           minimum timeout: 5.

       validate-all
           Performs a validation of the resource configuration. Suggested
           minimum timeout: 20.

EXAMPLE

       The following is an example configuration for a varnish resource using
       the crm(8) shell:

           primitive p_varnish ocf:heartbeat:varnish \
             params \
               config=string \
               mgmt_address=string \
             op monitor timeout="20" interval="10" depth="0"
