10
12 The Varnish Resource Agent can manage several varnishd instances
13 throughout the cluster. It does so by creating a unique PID file and
14 requires a unique listen address and name for each instance.
15
17 config
18 The VCL configuration file that Varnish should manage, for example
19 "/etc/varnish/default.vcl".
20
21 (unique, required, string, no default)
22
23 name
24 Override the name of the instance that should be given to Varnish
25 (defaults to the resource identifier).
26
27 (unique, optional, string, default "RESOURCE_ID")
28
29 pid
30 Write the process's PID to the specified file. The default will
31 include the specified name, i.e.:
32 "/var/run/varnish_production.pid". Unlike what this help message
33 shows, it is most likely not necessary to change this parameter.
34
35 (unique, optional, string, default
36 "/var/run/varnishd_RESOURCE_ID.pid")
37
38 listen_address
39 Listen on this address:port, for example "192.168.1.1:80"
40
41 (unique, optional, string, default "0.0.0.0:80")
42
43 mgmt_address
44 Provide a management interface, for example "127.0.0.1:2222"
45
46 (unique, required, string, no default)
47
48 ttl
49 Specify a hard minimum time to live for cached documents.
50
51 (optional, integer, default 600)
52
53 varnish_user
54 Specify the name of an unprivileged user to which the child process
55 should switch before it starts accepting connections.
56
57 (optional, string, default "varnish")
58
59 varnish_group
60 Specify the name of an unprivileged group to which the child
61 process should switch before it starts accepting connections.
62
63 (optional, string, default "varnish")
64

67 memory and 'file' for a file backend.
68
69 (optional, string, default "malloc")
70
71 backend_size
72 Specify the size of the backend. For example "1G".
73

78 example /var/lib/varnish/mybackend.bin
79
80 (unique, optional, string, default

131 This resource agent supports the following actions (operations):
132
133 start
134 Starts the resource. Suggested minimum timeout: 20s.
135
136 stop
137 Stops the resource. Suggested minimum timeout: 20s.
138
139 monitor
140 Performs a detailed status check. Suggested minimum timeout: 20s.
141 Suggested interval: 10s.
142
143 status
144 Performs a status check. Suggested minimum timeout: 20s.
145
