Updating farmOS


New versions of farmOS are released on a regular basis, and it's important to stay up-to-date so that you can receive new features, bug fixes, and security patches when they become available. Find the latest farmOS version on the GitHub release page.

Update procedure

  1. Backup your database and files! Always do this before updating. Be ready and able to roll-back in the event that something goes wrong. Typically this can be done by creating a database dump and a tarball of your web/sites directory. If you are using Docker, be sure you can roll back to the previous image version. If you are using packaged releases, be sure you also keep a copy of the old farmOS codebase before updating.
  2. Update the farmOS codebase. This will depend on how you have deployed farmOS. See Updating via Docker or Updating via packaged releases below for specific instructions. If you are building a custom farmOS codebase with Composer see Updating dependencies.
  3. Run automated updates. Navigate to https://[hostname]/update.php in your browser and follow the steps to run automated updates. It is important to do this before using the new version of farmOS to ensure that any necessary changes to the database or configuration are made.
  4. Clear caches. farmOS caches can be cleared by going to https://[hostname]/admin/config/development/performance in your browser and clicking "Clear all caches", or via the command line with Drush: drush cr. Cache clearing is only necessary if no updates are performed during update.php, otherwise they will be cleared automatically.

Updating via Docker

If you have deployed farmOS via Docker you can update to a new version of farmOS by pulling the new Docker image version:

docker pull farmos/farmos:[version]

This can also be done by updating your docker-compose.yml file if you are using Docker Compose and restarting your containers.

Assuming that /opt/drupal/web/sites is the only directory persisted outside of the container, this will update the farmOS codebase, which is located in /opt/drupal within the container. See Persistence for more information.

Updating via packaged releases

If you have deployed farmOS via packaged releases you can update to a new version of farmOS by downloading the new release tarball and unpacking it in place of the old codebase, replacing everything except the web/sites directory. Be sure to replace (not merge) all files and directories.

Do not overwrite the web/sites directory, because it contains all your site-specific settings and uploaded files.

Maintenance mode

Optionally, you may put farmOS into "maintenance mode" to prevent users from accessing it during the update process. Navigate to https://[hostname]/admin/config/development/maintenance in your browser, enable maintenance mode, perform the update, confirm the new version works, then disable maintenance mode. If you are the only user of farmOS then this is not necessary, but be sure to run update.php before using the new version.


An alternative to running the automated updates by visiting update.php in your browser is to use the command-line tool Drush.

The Drush command for running updates is:

drush updb

If you are running farmOS in Docker with the standard Docker Compose configuration, you can run this command inside the container with:

docker compose exec www drush updb

Security releases

When there are security updates released for farmOS dependency modules, you may see the following message:

There is a security update available for your version of Drupal. To ensure the security of your server, you should update immediately! See the available updates page for more information.

The farmOS maintainers will update these dependencies in the development branch of farmOS as soon as possible, and if the vulnerabilities affect farmOS directly a new version will be tagged and released. Many vulnerabilities are mitigated by the fact that farmOS is only accessible to users with a login. In those cases the maintainers may deem a release unnecessary. This message can be disabled by uninstalling the "Update Manager" module.
