Zero Downtime build script

[oyatek]

Hi guys,

If you deploy on your own server, and if you do build as described in the docs - the site goes off for a minute.

I wanted to share my zero-downtime build script.

Create a file build.sh in the root folder:

#zero downtime deployment docusaurus

echo "Deploy starting..."

# Clear changes. This in case some files were accidentally changed on the remote server - they will block the "git pull" action.
git stash push --include-untracked 

# Get updates
git pull

# Install new deps
npm install || exit

# Build into a "temp" directory in the root folder
npx docusaurus build --out-dir ./temp || exit 

# If "temp" folder couldn't be created - exit
if [ ! -d "temp" ]; then
  echo '\033[31m temp directory not exists!\033[0m'
  exit 1;
fi

# Rename current build folder to build_old
mv build build_old

# Rename new build folder to build
mv temp build

# Delete old build folder
rm -rf build_old

# Reload the server (if you use pm2)
pm2 reload your_process_name --update-env

echo "Deploy done."

Then when you need to build the project and restart the server - just go the root folder and do this:

sh build.sh
