NEMS Linux Docker Container

Note

The NEMS Linux Docker Container is not yet publicly available. It is coming soon.

NEMS Linux for Docker IS NOT YET AVAILBLE.

Install NEMS Linux for Docker

Basic Installation

This command will launch a new Docker container called nemslinux using default settings:

docker run --hostname nems --mount
type=tmpfs,destination=/tmp,tmpfs-mode=1777 --mount
type=tmpfs,destination=/var/www/html/backup/snapshot,tmpfs-mode=1770
--restart=unless-stopped --stop-timeout 120 --name nemslinux -d
baldnerd/nemslinux:1.6_build1

Install NEMS Linux Docker Container on a Physical Network

Docker is unlike a standard deployment since by default (with a basic install) only the host computer will have access to it. That of course is not ideal for a NEMS Linux server if you wish to be able to administer it from multiple systems, view dashboards, or use a NEMS Warning Light.

While NEMS Linux will function fine on a Docker network (eg., 172.17.0.2), if you wish to have full access to your NEMS Server just as you would with a physical appliance, you will need to connect it to your physical network.

The two most common options for specifying a network is to use either DHCP or a Static IP Address:

Using DHCP

docker run --network=multi-host-network --hostname nems --mount
type=tmpfs,destination=/tmp,tmpfs-mode=1777 --mount
type=tmpfs,destination=/var/www/html/backup/snapshot,tmpfs-mode=1770
--restart=unless-stopped --stop-timeout 120 --name nemslinux -d
baldnerd/nemslinux:1.6_build1

Using Static IP

Change the sample 10.0.0.105 IP address to suit your needs.

docker network connect --ip 10.0.0.105 multi-host-network run --hostname
nems --mount type=tmpfs,destination=/tmp,tmpfs-mode=1777 --mount
type=tmpfs,destination=/var/www/html/backup/snapshot,tmpfs-mode=1770
--restart=unless-stopped --stop-timeout 120 --name nemslinux -d
baldnerd/nemslinux:1.6_build1

Please see Docker’s Network Connections documentation for more help.

With USB Support

To connect a USB device such as temper to your Docker-based NEMS Server, first determine its /dev assignment on your host, and then run NEMS as follows, replacing ttyUSB0 with your actual USB device:

docker run --device=/dev/ttyUSB0 --hostname nems --mount
type=tmpfs,destination=/tmp,tmpfs-mode=1777 --mount
type=tmpfs,destination=/var/www/html/backup/snapshot,tmpfs-mode=1770
--restart=unless-stopped --stop-timeout 120 --name nemslinux -d
baldnerd/nemslinux:1.6_build1

Initialize Your Docker-Based NEMS Server

Initializing a NEMS Server within a Docker Container is different than all other platforms.

On the Docker host, simply run:

docker exec -it nemslinux nems-init

Access NEMS Linux CLI

Should you have need to access the NEMS Linux CLI, you may do so by launching bash in your container.

docker exec -it nemslinux bash
