Archipelago-deployment-live: upgrading Drupal 8 to Drupal 9 (1.0.0-RC2 to 1.0.0-RC3)

What is this documentation for?

If you already have a well-set-up and well-loved Archipelago (RC2 or your own custom version) running Drupal 8 (D8), this documentation will allow you to update to Drupal 9 (D9) without major issues.

D8 is no longer supported as of the end of November 2021. D9 has been around for a little while and even if every module is not supported yet, what you need and want for Archipelago has long been D9-ready.

Requirements

  • An archipelago-deployment-live instance 1.0.0-RC2 (working, tested) deployed using provided instructions via Docker and running Drupal 8.
  • Basic knowledge and instincts (+ courage) on how to run Terminal Commands, composer and drush.
  • Patience. You can't skip steps here.
  • For Shell Commands documented here please copy line by line—not the whole block.

Backing up and preparing for the upgrade

Backups are always going to be your best friends. Archipelago's code, database and settings are mostly self-contained in your current archipelago-deployment-live repo folder, and backing up is simple because of that.

Step 1:

Shut down your docker-compose ensemble. Move to your archipelago-deployment-live folder and run this:

cd deploy/ec2-docker
docker-compose down

Step 2:

Verify that all containers are actually down. The following command should return an empty listing. If anything is still running, wait a little longer, and run the following comman again.

docker ps

Step 3:

Now let's tar.gz the whole ensemble with data and configs. As an example we will save this into your $HOME folder. As a good practice we append the current date (YEAR-MONTH-DAY) to the filename. Here we assume today is December 1st of 2021.

sudo tar -czvpf $HOME/archipelago-deployment-live-backup-20211201.tar.gz ../../../archipelago-deployment-live

The process may take a few minutes. Now let's verify that all is there and that the tar.gz is not corrupt.

tar -tvvf $HOME/archipelago-deployment-live-backup-20211201.tar.gz

You will see a listing of files. If corrupt (Do you have enough space? Did your ssh connection drop?) you will see the following:

tar: Unrecognized archive format

Step 4:

Restart your docker-compose ensemble, and wait a little while for all to start.

docker-compose up -d

Step 5:

Export/backup all of your live Archipelago configurations (this allows you to compare/come back in case you lose something custom during the upgrade).

docker exec esmero-php mkdir config/backup
docker exec esmero-php drush cex --destination=/var/www/html/config/backup

Good. Now it's safe to begin the upgrade.

Upgrading to 1.0.0-RC3

Step 1:

First we are going to disable modules that are not part of 1.0.0-RC3 or are not yet compatible with D9. Run the following command:

docker exec esmero-php drush pm-uninstall module_missing_message_fixer markdown webprofiler key_value webform_views

From inside your archipelago-deployment-live repo folder we are going to open up the file permissions for some of your most protected Drupal files.

cd ../../
sudo chmod 777 drupal/web/sites/default
sudo chmod 666 drupal/web/sites/default/*settings.php
sudo chmod 666 drupal/web/sites/default/*services.yml

Step 2:

Time to fetch the 1.0.0-RC3 branch and update our docker-compose and composer dependencies. We are also going to stop the current docker ensemble to update all containers to newer versions:

cd deploy/ec2-docker
docker-compose down
git checkout 1.0.0-RC3

Then copy the appropriate docker-compose file for your architecture:

??? info "OSX (macOS)/x86-64"

```shell
cp docker-compose-osx.yml docker-compose.yml
```

??? info "Linux/x86-64/AMD64"

```shell
cp docker-compose-linux.yml docker-compose.yml
```

??? info "OSX (macOS)/Linux/ARM64"

```shell
cp docker-compose-arm64.yml docker-compose.yml
```

Finally, pull the images, and bring up the ensemble:

docker compose pull
docker compose up -d

Give all a little time to start. The latest min.io adds a new console, and your Solr core and Database need to be upgraded. Please be patient. To ensure all is well, run (more than once if necessary) the following:

docker ps

You should see something like this:

CONTAINER ID   IMAGE                                    COMMAND                  CREATED          STATUS          PORTS                                                           NAMES

Important here is the STATUS column. It needs to be a number that goes up in time every time you run docker ps again (and again).

Step 3:

Now we are going to tell composer to actually fetch the new code and dependencies using the 1.0.0-RC3 provided composer.lock and update the whole Drupal/PHP/JS environment.

docker exec -ti esmero-php bash -c "composer install"

This will fail (sorry!) for a few packages but no worries, they need to be patched and composer is not that smart. So simply run it again:

docker exec -ti esmero-php bash -c "composer install"

Well done! If you see no issues and all ends in a Green colored message all is good! Jump to Step 4

What if not all is OK and I see red and a lot of dependency explanations?

If you have manually installed packages via composer in the past that are NO longer Drupal 9 compatible you may see errors. In that case you need to check each package website's (normally https://www.drupal.org/project/the_module_name) and check if there is a Drupal 9 compatible version.

If so run:

docker exec -ti esmero-php bash -c "composer require 'drupal/the_module_name:^VERSION_NUMBER_THAT_WORKS_ON_DRUPAL9_' --update-with-dependencies --no-update" and run **Step 3 ** again (and again until all is cleared)

If not: try to find a replacement module that does something simular, but in any case you may end having to remove before proceding. Give us a ping/slack/google group/open a github ISSUE if you find yourself uncertain about this.

docker exec -ti esmero-php bash -c "composer remove drupal/the_module_name --no-update"
docker exec -ti esmero-php bash -c " drush pm-uninstall the_module_name"

Step 4:

We will now ask Drupal to update some internal configs and databases. They will bring you up to date with RC3 settings and D9 particularities.

docker exec -ti esmero-php bash -c 'scripts/archipelago/setup.sh'
docker exec -ti esmero-php bash -c 'drush urol administrator "admin"'
docker exec -ti esmero-php bash -c "drush updatedb"

Step 5:

Previously D8 installations had a "module/profile" driven installation. Those are no longer used or even exist as part of core, but a profile can't be changed once installed so you have to do the following to avoid Drupal complaining about our new and simpler way of doing things (a small roll back):

docker exec -ti esmero-php bash -c "sed -i 's/minimal: 1000/standard: 1000/g' config/sync/core.extension.yml"
docker exec -ti esmero-php bash -c "sed -i 's/profile: minimal/profile: standard/g' config/sync/core.extension.yml"

Step 6:

Now you can Sync your new Archipelago 1.0.0-RC3 and bring all the new configs and settings in. For this you have two options (no worries, remember you made a backup!):

A Partial Sync, which will bring new configs and update existing ones but will not remove ones that only exist in your custom setup, e.g. new Webforms or View Modes.

docker exec esmero-php drush cim -y --partial

A Complete Sync, which will bring new configs and update existing ones but will also remove all the ones that are not part of RC3. It's a like clean factory reset.

docker exec esmero-php drush cim -y

If all goes well here and you see no errors it's time to reindex Solr because there are new Fields. Run the following:

docker exec esmero-php drush search-api-reindex
docker exec esmero-php drush search-api-index

You might see some warnings related to modules dealing with previously non-existent data—no worries, just ignore those.

If you made it this far you are done with code/devops (are we ever ready?), and that means you should be able to (hopefully) stay in the Drupal 9 realm for a few years!

Step 7: Update (or not) your Metadata Display Entities and Menu items.

Recommended: If you want to add new templates and menu items 1.0.0-RC3 provides, run this:

docker exec -ti esmero-php bash -c 'scripts/archipelago/deploy.sh'

Once that is done, you can choose to update all Metadata Displays (Twig templates) we ship with new 1.0.0-RC3 versions (heavily fixed IIIF manifest, Markdown to HTML for Metadata, better Object descriptions). But before you do this, we really recommend that you first make sure to manually (copy/paste) backup any Twig templates you have modified. If unusure, do not run the command that comes after this warning! You can always manually copy the new templates from the d8content/metadatadisplays folder which contains text versions (again, copy/paste) of each shipped template you can pick and use when you feel ready.

If you are sure (like really?) you want to overwrite the ones you modified (sure, just checking?), then you can run this:

docker exec -ti esmero-php bash -c 'scripts/archipelago/update_deployed.sh'

Done! (For realz now)

Please log into your Archipelago and test/check all is working! Enjoy 1.0.0-RC3 and Drupal 9. Thanks!
