How to define Hugo version?

9

I have a slightly updated version of what @John_B posted above. This works for me. However, I am not sure how long the build cache stays around. If it stays around until you manually clear build cache and trigger a manual deploy, then it’s likely that the Hugo version will be whatever was last installed. I think this is a great starting point, though.

#!/bin/bash

# In your Render dashboard, set the HUGO_VERSION env var for your static site. You'll get the same experience as, say, Netlify.

TAR_NAME="hugo_extended_${HUGO_VERSION}_Linux-64bit.tar.gz"

hugo version # Output the OLD version
if [[ ! -f $XDG_CACHE_HOME/hugo ]]; then 
  echo "...Downloading HUGO" 
  mkdir -p ~/tmp 
  wget -P ~/tmp https://github.com/gohugoio/hugo/releases/download/v${HUGO_VERSION}/${TAR_NAME} 
  cd ~/tmp
  echo "...Extracting HUGO" 
  tar -xzvf ${TAR_NAME}
  echo "...Moving HUGO"
  mv hugo $XDG_CACHE_HOME/hugo  
  # Make sure we return to where we were.
  cd $HOME/project/src
else 
  echo "...Using HUGO from build cache"
fi

$XDG_CACHE_HOME/hugo version

# Render sets IS_PULL_REQUEST to true for PR previews.
if [ "${IS_PULL_REQUEST:-}" = "true" ]; then
    $XDG_CACHE_HOME/hugo --gc -e preview
else
    $XDG_CACHE_HOME/hugo --gc --minify
fi
