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 "RESOURCE_ID")

       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_RESOURCE_ID.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/RESOURCE_ID.bin")

       threads_pools
           Number of worker thread pools. Each pool has the minimum, maximum and timeout values
           configured in the thread_pool_min, thread_pool_max and thread_pool_timeout parameters

           (optional, string, default "2")

       thread_pool_min
           Start at least min but no more than max worker threads with the specified idle timeout
           in each pool.

           (optional, string, default "100")

       thread_pool_max
           Start at least min but no more than max worker threads with the specified idle timeout
           in each pool.

           (optional, string, default "3000")

       thread_pool_timeout
           Start at least min but no more than max worker threads with the specified idle timeout
           in each pool.

           (optional, string, default "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")

       secret
           Path to a file containing a secret used for authorizing access to the management port.

           (optional, string, default "/etc/varnish/secret")
