Nginx Container

To host my Hugo generated static site I’ll need a web server.

For this task I have chosen to use nginx.

The container image will actually be build during deployment using a pipeline. More on that in a later post.

Containerfile

Let’s first take a look at the containerfile. It’s not overly complicated as I don’t need anything special.

Basically I am taking a standard nginx (alpine based) image and copying my site files as well as a configuration file into the container image.

FROM nginx:alpine
COPY public /usr/share/nginx/html
COPY jenkins/default.conf /etc/nginx/conf.d/default.conf

nginx configuration

The configuration file for nginx is also quite simple.

server {
    listen       80;
    server_name  localhost;

    location / {
        add_header Content-Security-Policy "default-src 'self'; img-src *; style-src 'self' 'unsafe-inline';";
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

It listens on localhost port 80. Has the location for the files defined as well as some security headers.

The unsafe-inline parameter is necessary for the syntax highlighting to work.

Build

For completeness here is the build command.

docker build -t hugo-nginx:teknikuglen -f Containerfile .

Parting words

So that’s another image ready for deployment.
