Updating docker version

nextushka · December 19, 2019, 2:29pm

Hi. I’m using docker-compose version of Nextcloud with the named volume:
volumes:
- nextcloud:/var/www/html

Am I right that trying to update the image with “docker-compose pull” will not update my Nextcloud as it picks /var/www/html folder from my host disk using that volume?
What is the correct way to update in such case?
Or I’m missing something?

no. you are wrong.

the entrypoint.sh of the image will check if your version in /var/www/html is lower then the version in the image and will perform an update on first startup.

              installed_version="$(php -r 'require "/var/www/html/version.php"; echo implode(".", $OC_Version);')"
          fi
          # shellcheck disable=SC2016
          image_version="$(php -r 'require "/usr/src/nextcloud/version.php"; echo implode(".", $OC_Version);')"
          
          if version_greater "$installed_version" "$image_version"; then
              echo "Can't start Nextcloud because the version of the data ($installed_version) is higher than the docker image version ($image_version) and downgrading is not supported. Are you sure you have pulled the newest image version?"
              exit 1
          fi
          
          if version_greater "$image_version" "$installed_version"; then
              echo "Initializing nextcloud $image_version ..."
              if [ "$installed_version" != "0.0.0.0" ]; then
                  echo "Upgrading nextcloud from $installed_version ..."
                  run_as 'php /var/www/html/occ app:list' | sed -n "/Enabled:/,/Disabled:/p" > /tmp/list_before
              fi
              if [ "$(id -u)" = 0 ]; then
                  rsync_options="-rlDog --chown www-data:root"
              else
                  rsync_options="-rlD"
              fi

docker stop, docker rm, docker-compose up
