Tested on Ubuntu Xenial

Using this docker container:
https://hub.docker.com/r/edacoreinfra/meetbot/
https://github.com/edacore-infra/docker-meetbot

Take a very small VM dedicated for this:

{{{
sudo su
mkdir -p /root/docker-meetbot/conf
mkdir -p /root/docker-meetbot/logs
mkdir -p /root/docker-meetbot/data
echo "deb http://apt.dockerproject.org/repo ubuntu-xenial main" > /etc/apt/sources.list.d/docker.list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F76221572C52609D
sudo apt-get update
sudo apt-get install docker-engine
docker run --name="meetbot-running" -d --network=host \
          --env NICK="meetbot-ninux" \
          --env IRC_SERVERS="irc.freenode.net:6667" \
          --env IRC_CHANNELS="#ninux.org" \
          --env URL_INFO="http://meetbot.ninux.org" \
          --env LOG_URL_PREFIX="http://meetbot.ninux.org" \
          --env LOG_DIR="/data/public_html/" \
          --env LOG_PATTERN="%(meetingname)s/%%Y/%(meetingname)s.%%F-%%H.%%M" \
          -v /root/docker-meetbot/conf:/conf \
          -v /root/docker-meetbot/data:/data \
          -v /root/docker-meetbot/logs:/logs edacoreinfra/meetbot
}}}

Use a small web server to serve /root/docker-meetbot/data

{{{
docker run --network=host --name some-nginx \
       -v /root/docker-meetbot/data/public_html/:/usr/share/nginx/html:ro \
       -v /root/default.conf:/etc/nginx/conf.d/default.conf \
       -d nginx
}}}
