Set a hugo blog on Kubernetes

Here are some steps to containerize a blog using hugo + docker + kubernetes + quay

Since last year I been trying to become an SRE (Site Reliability Engineer), so I been involved with some emerging technologies, like ansible, docker and on this time with kubernetes.

This time, I will try to explain how I containerized my blog using:


So, I take some ideas from here and I modify them and adapt the architecture described to my options.

The principal changes that I made are:

  • My Kubernetes cluster is running on 2 cloud server on Rackspace Public Cloud
  • The container registry that I’m using is Quay
  • Rackspace Public Cloud does not support a Kubernetes LoadBalancer service automatically, so I simulate that behavior adding a Cloud Load Balancer manually after the Kubernetes service provide me the port.


I use Hugo to deploy my blog, I used to do it as mentioned on this previous post (In Spanish).

Now, as a part of containerize the blog it make sense to me to create two stages as described here:

  • The first stage is a defined build environment containing all required build tools (hugo, pygments) and the source of the website (Git repository).
  • The second stage is the build artifact (HTML and assets), from the first stage and a webserver to serve the artifact over HTTP.


Here is the Dockerfile that containerize the blog:

FROM ubuntu:latest as STAGEONE

# install hugo
ADD${HUGO_VERSION}/hugo_${HUGO_VERSION}_Linux-64bit.tar.gz /tmp/
RUN tar -xf /tmp/hugo_${HUGO_VERSION}_Linux-64bit.tar.gz -C /usr/local/bin/

# install syntax highlighting
RUN apt-get update
RUN apt-get install -y python3-pygments

# build site
COPY source /source
RUN hugo --source=/source/ --destination=/public/

FROM nginx:stable-alpine
RUN apk --update add curl bash
RUN rm /etc/nginx/conf.d/default.conf
COPY modules/ /etc/nginx/conf.d/
COPY --from=STAGEONE /public/ /usr/share/nginx/html/
EXPOSE 80 443

First Stage

  • Fetch the lastest Ubuntu image and name as STAGEONE
  • Install the last available hugo version from source.
  • Install pygments library to use it for highlighting.
  • Build the site with hugo and the output is set on /public as a build artifact.

Second Stage

  • Fetch the lastest stable nginx alpine image.
  • Update the image and install some utilities.
  • Delete the default nginx configuration file.
  • Copy the configuration files needed from the repository root directory.
  • Copy the build artifact /public from the previous stage (STAGEONE)
