Dockerized Glass - ISC DHCP Server Interface
I have a ISC DHCP server which provides my lab environment with IP addreses and I was curious if there was a GUI that would allow one to view leases and other information. As it happens it does. I found the Glass project on github.
However it had the requirement of running nodejs on my precious DHCP server. I was sceptical but gave it a try. I did enjoy the Glass application and decided that running docker on my server was somewhat better than installing nodejs.
This is how I dockerized Glass.
mkdir glass && cd glass
FROM node:8-slim MAINTAINER dodgydudes RUN apt-get update && apt-get -y --no-install-recommends install git && git clone https://github.com/Akkadius/glass-isc-dhcp.git /opt/glass WORKDIR /opt/glass RUN mkdir logs && chmod u+x ./bin/ -R && chmod u+x *.sh && npm install VOLUME /var/lib/dhcp/dhcpd.leases /var/log/dhcp.log /etc/dhcp/dhcpd.conf /opt/glass/config EXPOSE 3000 ENTRYPOINT ["npm", "start"]
Build the image.
docker build -t glass .
Create a volume to store the Glass configuration file.
docker volume create glass-config
Find where your
dhcpd.conf are located, you need to bind mount them to the docker container. Below you can see where they were on my CentOS 7 system.
docker run --name glass --hostname dhcp -tid \ -v /var/lib/dhcpd/dhcpd.leases:/var/lib/dhcp/dhcpd.leases:ro \ -v /var/log/dhcp.log:/var/log/dhcp.log:ro \ -v /etc/dhcp/dhcpd.conf:/etc/dhcp/dhcpd.conf:ro \ -v glass-config:/opt/glass/config -p 3000:3000 glass:latest
