The NEMS Linux Docker Container is coming soon. It is currently in heavy testing. If you decide to try it, please do not do so in a production environment, and be sure to report any issues on our Discord server.

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

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:

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

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.

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

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

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
