After restarting my blog, I wanted a way to automate my workflow. I currently work for AWS, and want to use the features of the cloud to manage and deploy my blog, but for as little cost as possible. The lowest cost for a static site like mine is Amazon S3, which offers to host the objects in the bucket as a static website.
This starts by adopting a solid framework for building static sites. After trying a few, I selected Hugo. I had been using mkdocs for training/tutorials but felt it lacked a good native layout engine and wasn’t a good fit for a blog.
FROM centos:latest as builder RUN yum -y update RUN curl -sL -o hugo.tar.gz https://github.com/gohugoio/hugo/releases/download/v0.46/hugo_0.46_Linux-64bit.tar.gz && tar zxf hugo.tar.gz hugo FROM scratch COPY --from=builder /hugo . VOLUME /host WORKDIR /host EXPOSE 1313 ENTRYPOINT ["/hugo"]
While a simple example, it does combine some newer Docker features. I used a multi-stage build to download the actual binary, then a scratch image for the actual deployment. The README highlights the syntax I use for the command, and an alias for being able to run
hugo new posts/docker-hugo.md with all of my environment variables already plugged in. This can also be adapted for a future CI/CD process.
