Consul with SMF on Solaris
Whilst setting up consul on SmartOS I noticed the packages distributed through pkgsrc were lagging behind a bit and the upstream “distribution” contains only the consul binary.
Running consul -dev
in a tmux window will get boring pretty quickly, so I came up with the following SMF manifest using manifold which supports start, stop and refresh (triggers a configuration reload):
<?xml version="1.0"?>
<!DOCTYPE service_bundle SYSTEM "/usr/share/lib/xml/dtd/service_bundle.dtd.1">
<!--

-->
<service_bundle type="manifest" name="consul">
<service name="site/consul" type="service" version="1">

<single_instance/>
<dependency name="network" grouping="require_all" restart_on="error" type="service">
<service_fmri value="svc:/milestone/network:default"/>
</dependency>
<dependency name="filesystem" grouping="require_all" restart_on="error" type="service">

</dependency>
<method_context>
<method_credential user="consul" group="consul"/>
</method_context>
<exec_method type="method" name="start" exec="/usr/local/bin/consul agent -config-dir %{config_dir}" timeout_seconds="60"/>
<exec_method type="method" name="stop" exec=":kill" timeout_seconds="60"/>
<exec_method type="method" name="refresh" exec=":kill -HUP" timeout_seconds="10"/>
<property_group name="startd" type="framework">
<propval name="duration" type="astring" value="child"/>
<propval name="ignore_error" type="astring" value="core,signal"/>
</property_group>
<property_group name="application" type="application">
<propval name="config_dir" type="astring" value="/etc/consul.d"/>
</property_group>
<stability value="Evolving"/>
<template>
<common_name>
<loctext xml:lang="C">
Consul service discovery
</loctext>
</common_name>
</template>
</service>
</service_bundle>
Now import the manifest and start consul:
svccfg import consul.xml
svcadm enable consul
This was tested on SmartOS though it should work just fine on Solaris 10/11 and other illumos distributions.
