How to run HUGO under Docker

It is convenient to run such tool like Hugo (and many many others) under Docker, without installing it to a local machine. Here I will show you how to run Hugo under Docker, create new posts for the blog, generate static content - i.e. all basic operations that allow to add new and edit existing posts to the blog.

What docker image for Hugo to take

A lot of Hugo images are available on Docker Hub, let’s just take the most starred one: jojomi/hugo. One nice thing for this image is that it is updated on time and all versions of Hugo are available, starting from 0.15. I will show you how to run Hugo 0.19, but you can easily apply this knowledge to run Hugo of more late versions.

How to run hugo from docker

First, let’s have two folders:

  • src - for sources of our site
  • output - for generated output

Then, let’s do following:

  • create some simple site (let it be blog) structure
  • download theme
  • run site on localhost
  • then generate html from out content

Create simple site structure

Inside our src folder we have following content:

  • config.toml - file with config
  • content - folder with blog content
  • static - folder with static assets (images/css/scripts/etc)
  • themes - folder which contain one or more theme we want to employ for our website

To see example of initial folder, see it on github: https://github.com/iryndin/hugoblog

Folder themes should contain Hugo theme which we are going to use. For this example, let it be hugo-redlounge.

Now, let’s run Hugo docker image to run a webserver on localhost, so that we would be able to look at our website in browser:

docker run --rm --name "hugo1" -p 1313:1313 -v $(pwd)/src:/src -v $(pwd)/output:/output -e HUGO_THEME="hugo-redlounge" -e HUGO_WATCH="true" jojomi/hugo:0.26

Now we will be able to see our website in browser at http://localhost:1313

Creating new post

To create new post, run following command:

docker exec -it hugo1 hugo new post/example3.md

New file for this post will be created, and you can immediately start editing it.

Generate static content

Now let’s generate static content for our site. To generate static content in output2 folder you need to run command similar to what we used to run webserver on localhost, but without HUGO_WATCH variable and without necessity to map ports. Also, you should run it under another name, if you do not want to shutdown container named hugo1 (that used in this example to run local webserver).

docker run --rm --name "hugo2" -v $(pwd)/src:/src -v $(pwd)/output2:/output -e HUGO_THEME="hugo-redlounge" jojomi/hugo:0.26

And you will have your static site in output2 folder.
