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, i.e.: "/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
           Specify a hard minimum time to live for cached documents.

           (optional, integer, default 600)

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

           (optional, string, default "varnish")

       varnish_group
           Specify 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")

       maxfiles
           Maximum number of open files (for ulimit -n)

           (optional, string, default "131072")

       max_locked_memory
           Locked shared memory limit (for ulimit -l)

           (optional, string, default "82000")

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 CRM SHELL

       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"

EXAMPLE PCS

       The following is an example configuration for a varnish resource using pcs(8)

           pcs resource create p_varnish ocf:heartbeat:varnish \
             config=string \
             mgmt_address=string \
