# Configuration file for varnish
#
# /etc/init.d/varnish expects the variables $DAEMON_OPTS, $NFILES and $MEMLOCK
# to be set from this shell script fragment.
#
# Note: If systemd is installed, this file is obsolete and ignored.  Please see
# /usr/share/doc/varnish/examples/varnish.systemd-drop-in.conf

# Should we start varnishd at boot?  Set to "no" to disable.
START=yes

# Maximum number of open files (for ulimit -n)
NFILES=131072

# Maximum locked memory size (for ulimit -l)
# Used for locking the shared memory log in memory.  If you increase log size,
# you need to increase this number as well
MEMLOCK=82000

# Default varnish instance name is the local nodename.  Can be overridden with
# the -n switch, to have more instances on a single server.
# You may need to uncomment this variable for alternatives 1 and 3 below.
# INSTANCE=$(uname -n)

# This file contains 4 alternatives, please use only one.

## Alternative 1, Minimal configuration, no VCL
#
# Listen on port 6081, administration on localhost:6082, and forward to
# content server on localhost:8080.  Use a 1GB fixed-size cache file.
#
# This example uses the INSTANCE variable above, which you need to uncomment.
#
# DAEMON_OPTS="-a :6081
#              -T localhost:6082
#        -b localhost:8080
#        -u varnish -g varnish
#            -S /etc/varnish/secret
#        -s file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G"


## Alternative 2, Configuration with VCL
#
# Listen on port 6081, administration on localhost:6082, and forward to
# one content server selected by the vcl file, based on the request.
#
DAEMON_OPTS="-a :80
             -T localhost:6082
             -f /etc/varnish/default.vcl
             -S /etc/varnish/secret
             -s malloc,256m"


## Alternative 3, Advanced configuration
