A Dockerized SNMP emulator useful for testing and development.
This project is just the Python snmpsim package bundled up into a
Docker image along with SNMP MIB walks, making it easy to deploy an emulator for
testing SNMP consumers, such as Synse plugins.
docker pull vaporio/snmp-emulator
snmpsim is run within the container via the start_snmp_simulator.sh script.
It provides some lightweight initial context logging to /logs/$3 and then kicks off the simulator
with the following arguments:
--data-dir="$1"
--agent-udpv4-endpoint=0.0.0.0:$2
--v3-user=simulator
--v3-auth-key=auctoritas
--v3-auth-proto=$6
--v3-priv-key=privatus
--v3-priv-proto=$7
The --data-dir argument takes a value passed to the container. This should be the relative path to the
.snmpwalk file that you want to load.
To configure the emulator to run with data from the Pxgms (Eaton) UPS, nulling out the log file:
$ docker run vaporio/snmp-emulator /snmp_data/device/ups/pxgms_ups/public.snmpwalk 1024 ../dev/null V3 authPriv SHA AES
The agent endpoint always uses the host 0.0.0.0 in order for the container
to properly expose the endpoint.
