Hugo docker

An alpine docker image with hugo, openssh and git. Used in my CI pipelines.

It comes without the hugo entrypoint.

Usage

To build your hugo site in the default public directory:

docker run -v "${PWD}:/site" alombarte/hugo hugo

Use a different hugo version

Available versions are here. To add another version just build the image passing the desired version, e.g.:

export VERSION=0.55.6 && docker build -t alombarte/hugo:${VERSION} --build-arg VERSION=${VERSION} .

Integration on Gitlab and Github

The following file is an example on how to build a hugo site hosetd on a private repo (Gitlab) and deploy it into a public Github repo (the generated HTML). Yes, you could the whole thing on Gitlab :)

Make sure to set the variables in the configuration:

• $USERNAME
• $REPOSITORY
• $EMAIL
• $GH_TOKEN (the token provided by github so you can push without your password)
