I figured a good way of kicking off this site would be writing how it’s set up. I have it deployed on linode using Hugo and the NGINX docker container. The idea being that when I’m experimenting, I can easily deploy containers with whatever services I’m building and use NGINX as a frontend.

Remote login and user setup.

After creating my linode, the first thing I did was setup a sudo user and disabled root login in ssh.

first things first:

root@ubuntu:~# adduser myuser
root@ubuntu:~# usermod -aG sudo myuser

At this point, I log out as root and log in as my new user. I then disabled root login in the sshd config:

# /etc/ssh/sshd_config
...
# Authentication:
LoginGraceTime 120
PermitRootLogin no
StrictModes yes
...

And restarted sshd:

myuser@ubuntu:~$ sudo /etc/init.d/ssh restart

I then went on to install docker:

myuser@ubuntu:~$ sudo apt-get install dmsetup && dmsetup mknodes
myuser@ubuntu:~$ sudo curl -sSL https://get.docker.com/ | sh

I also added my user to the docker group:

myuser@ubuntu:~$ sudo usermod -aG docker elfredpagan

and Installed docker compose:

myuser@ubuntu:~$ sudo apt install docker-compose

At this point I have a working docker and docker-compose installation. Now I installed Hugo.

myuser@ubuntu:~$ wget https://github.com/spf13/hugo/releases/download/v0.18.1/hugo_0.18.1-64bit.deb
myuser@ubuntu:~$ sudo dpkg -i hugo*.deb

And pulled my repository

myuser@ubuntu:~$ git clone $github_url:repository
myuser#ubuntu:~$ cd repository

My repository has a site folder that contains a Hugo site. Hugo builds your site in the public folder, so I have a docker-compose.yml file that looks as follows.

web:
  image: "nginx:alpine"
  ports:
    - "80:80"
    - "443:443"
  volumes:
    - "./site/public:/usr/share/nginx/html"

I then have a startup script that runs docker-compose up to start the http service.

That’s pretty much it for now, I have to setup a cron job to poll the github repository and rebuild the site as needed. I also expect to export the nginx configuration to a mapped volume as things get more complex.
