Install a sensor in a Docker container

Docker is the approved software for a container installation on Nozomi Networks Operating System (N2OS). Do this procedure to run a Nozomi Networks sensor in a Docker environment.

To run the image, enter a command such as:

docker run --hostname=nozomi-sga --name=nozomi-sga \
--volume=<path_to_data_folder>:/data --network=host \
--mount type=tmpfs,destination=/var/sandbox,tmpfs-size=400M \
--mount type=tmpfs,destination=/var/tmp_sandbox,tmpfs-size=100M \
--mount type=tmpfs,destination=/var/pipes,tmpfs-size=10M \
--mount type=tmpfs,destination=/var/traces,tmpfs-size=400M \
--mount type=tmpfs,destination=/var/checksums,tmpfs-size=25M \
-d n2os

Note: <path_to_data_folder> is the path to a volume where the sensor's data will be stored, and saved for future runs.

The sensor will monitor all network interfaces available to the container. Use the --network=host option to give the container full access to all network interfaces of the host computer.
