# Deployment


*Build action* process:
```
# copy database parameters
cp "$DPSETTINGSPATH" docroot/sites/default/settings.production.php

# fix chmods
chmod 644 docroot/sites/default/settings.production.php
chmod 644 docroot/sites/default/settings.php
chmod 644 docroot/sites/default/services.yml

# remove devel files
rm docroot/sites/default/settings.local.php
rm docroot/sites/development.services.yml

# create build folder and move all content into this
mkdir -p builds/${BUILD_ID}
find . ! -name . -prune ! -path ./builds \
     -exec mv {} builds/${BUILD_ID} \;
     
# move in
cd builds/${BUILD_ID}

# run it
#composer clearcache
composer install --no-dev

# download libraries
cd docroot/libraries
bower install
cd ../../

# hot fix - meta tag plugin:
mv docroot/modules/contrib/metatag/metatag_mobile/src/Plugin/metatag/Tag/MsapplicationStarturl.php docroot/modules/contrib/metatag/metatag_mobile/src/Plugin/metatag/Tag/MsapplicationStartUrl.php

# create archive
cd ../../
tar --exclude=".git" -pczf build.tar.gz builds
```

We have interesting folder structure for virtual hosts, because its useful.
In root must be foders:
- data (static files uploaded via admin), setup for symlink to the build folder
- builds
    - {number} - build number with repository state after composer install and theme deployment
- live - symlink to last active build, setup as virtual host root

Here are symlinks for *Post-build Actions* on destination server: 

```
cd ~/yourdomain.cz
tar -xzf build.tar.gz
rm build.tar.gz

# find active build
BUILD_ACTUAL=$(ls -l live | sed 's/^.* -> //')

# backup actual database
cd ${BUILD_ACTUAL}/docroot
drush config-export -y
drush sql-dump --skip-tables-list=cache,cache_* > ../tmp/private/dump-before-next-build.sql
cd ../../..

pwd

# make live actual build
LIVE=/home/hf/yourdomain.cz/live
if [ ! -L $LIVE ]; then
    ln -s builds/${BUILD_ID}/ $LIVE
else
    rm $LIVE
    ln -s builds/${BUILD_ID}/ $LIVE
fi

# remove auto-generated empty folder
rm -r /home/hf/yourdomain.cz/live/docroot/sites/default/files

# make symlink with data to actual build
ln -sT ../../../../../data/sites/default/files/ /home/hf/yourdomain.cz/live/docroot/sites/default/files

# go to root
cd builds/${BUILD_ID}/docroot

# maintenance
drush sset system.maintenance_mode 1

# clear drush cache
drush cache-clear drush

# run config/sync, database updates
drush config-import -y
drush updb -y
#drush entity-updates

# allow uglify
drush -y config-set system.performance css.preprocess 1
drush -y config-set system.performance js.preprocess 1

# clear cache
drush cr

# go live
drush sset system.maintenance_mode 0

# delete two oldest builds
BCOUNT=$(find . -mindepth 1 -maxdepth 1 -type d | wc -l);
FOLDERS=$(ls -t1 | tail -n2);
if [ $BCOUNT -gt "6" ]; then 
  echo "Deleting oldest builds:"; 
  echo $FOLDERS; 
  rm -rf $FOLDERS; 
fi
