add headers to embed nextcloud in frame on external site

This introduces new env variables to configure nextloud to be embedded via
iframe on an external site.
Setting X_FRAME_OPTIONS_ENABLED=1 will configure nginx and nextcloud to
set X-Frame-Options and CSP headers to allow the domain configured in
X_FRAME_OPTIONS_ALLOW_FROM.

 # Nextcloud
 
-Wiki Cafe's configuration for a Nextcloud deployment. Originally slimmed down from an `abra` [recipe](https://git.coopcloud.tech/coop-cloud/nextcloud) by [Co-op Cloud](https://coopcloud.tech/).
+[![Build Status](https://drone.autonomic.zone/api/badges/coop-cloud/nextcloud/status.svg)](https://drone.autonomic.zone/coop-cloud/nextcloud)
 
+Fully automated luxury Nextcloud via docker-swarm.
 
-This setup works in conjunction with [Caddy reverse proxy](https://git.coopcloud.tech/coop-cloud/caddy), handling TLS certificates via Let's Encrypt. This setup also includes labels for optional integration with [backupbot](https://git.coopcloud.tech/coop-cloud/backup-bot-two) for automated backups.
+<!-- metadata -->
+* **Category**: Apps
+* **Status**: 2, beta
+* **Image**: [`nextcloud`](https://hub.docker.com/_/nextcloud), 4, upstream
+* **Healthcheck**: Yes
+* **Backups**: No
+* **Email**: 3
+* **Tests**: 2
+* **SSO**: 1 (OAuth)
+<!-- endmetadata -->
 
+## Basic usage
 
-## Deploying the app with Docker Swarm
+1. Set up Docker Swarm and [`abra`]
+2. Deploy [`coop-cloud/traefik`]
+3. `abra app new nextcloud --secrets` (optionally with `--pass` if you'd like
+   to save secrets in `pass`)
+4. `abra app YOURAPPDOMAIN config` - be sure to change `$DOMAIN` to something that resolves to
+   your Docker swarm box
+5. `abra app YOURAPPDOMAIN deploy`
 
-Create a new file `.env` in this directory with the following contents, adjusting as necessary:
+## How do I customise the default home page when logging in?
+
+- Delete the dashboard app since it is so corporate
+- Follow [these docs](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/default_files_configuration.html) to set the default files list for each user in the Files app
+- Configure a `defaultapp` in your `config.php` or use [apporder](https://apps.nextcloud.com/apps/apporder)
+
+## Running `occ`
+
+`abra app run --user www-data YOURAPPDOMAIN app occ user:list --help`
+
+## Upgrading Nextcloud apps
+
+`abra app run --user www-data YOURAPPDOMAIN app occ app:update --all`
+
+## How do I fix a Nextcloud version snafu?
+
+`Exception: Updates between multiple major versions and downgrades are unsupported.`
+
+Solution:
+
+- Look at log files to determine the old Nextcloud version
+- Change your local `~/.abra/recipes/nextcloud/compose.yml` to the highest minor
+    version in the old version -- e.g. choose `22.2.5` for `22`, if you're
+    upgrading to `23`.
+- Then, do one of (both bad):
+  1. `abra app deploy --chaos ...`, then `app run` to go in and manually lower the version number in PHP (shell in, `apt install vim-core && vi version.php`), then try `php ./occ upgrade`
+  2. `abra app undeploy ...`, `abra volume rm`, CAREFULLY only choose the volume
+     ENDING `_nextcloud`, then `abra app deploy --chaos ...`, then edit the
+     `compose.yml` to add `entrypoint: ['tail', '-f', '/dev/null']` to `app`,
+     then `app deploy --chaos` again, then `app run --user=www-data ... app bash` to get in and run `./occ maintenance:repair`, and `./occ upgrade`. 
+- Change `compose.yml` to the new version number; `git checkout compose.yml`
+- `abra app deploy --force`
+- This wasn't even multiplle major versions was it 😾
+
+## How do I integrate with Keycloak SSO?
+
+Use [this plugin](https://github.com/pulsejet/nextcloud-oidc-login). Unlike the plugin it's forked from, there is no configuration UI, so you'll need to edit `/var/www/html/config/config.php`:
 
 ```
-STACK_NAME=nextcloud
-DOMAIN=nextcloud.example.com
-## Domain aliases
-#EXTRA_DOMAINS=', `www.nextcloud.example.com`'
-LETS_ENCRYPT_ENV=production
-
-ADMIN_USER=admin
-
-EXTRA_VOLUME=/dev/null:/tmp/.dummy
-
-PHP_MEMORY_LIMIT=1G
-# fpm-tune, see: https://spot13.com/pmcalculator/
-FPM_MAX_CHILDREN=128
-FPM_START_SERVERS=32
-FPM_MIN_SPARE_SERVERS=32
-FPM_MAX_SPARE_SERVERS=64
-
-DEFAULT_QUOTA="500 MB"
-
-# X_FRAME_OPTIONS_ENABLED=1
-# X_FRAME_OPTIONS_ALLOW_FROM=embedding-site.example.org
-
-# SMTP Config
-# See https://github.com/nextcloud/docker#auto-configuration-via-environment-variables for default values
-SMTP_AUTHTYPE=LOGIN
-SMTP_HOST=mail.example.com
-SMTP_SECURE=tls
-SMTP_NAME=mail@example.com
-SMTP_PORT=587
-MAIL_FROM_ADDRESS=cloud
-MAIL_DOMAIN=example.com
-
-# Database tuning variables
-INNODB_BUFFER_POOL_SIZE=1G
-MAX_DB_CONNECTIONS=256
+  'oidc_login_client_id' => 'nextcloud',
+  'oidc_login_client_secret' => 'mysecret',
+  'oidc_login_provider_url' => 'https://example.com/auth/realms/myrealm',
+  'oidc_login_disable_registration' => false,
+  'oidc_login_hide_password_form' => true,
+  'oidc_login_button_text' => 'Log in with your myssodomain',
+  'oidc_login_default_group' => 'mygroup',
+  'oidc_login_attributes' =>
+  array (
+    'id' => 'sub',
+    'name' => 'name',
+    'mail' => 'email',
+  ),
+  'oidc_create_groups' => true,
 ```
 
-Set the environment variables from the .env file during the shell session:
+You can use [this trick](https://janikvonrotz.ch/2020/10/20/openid-connect-with-nextcloud-and-keycloak/) (see "Cryptic Usernames" work-around) to get proper usernames.
+
+If you ever need to change the realm, you'll need to reset the cache with:
 
 ```
-set -a && source .env && set +a
+docker exec -u www-data <container-id> php occ config:app:delete oidc_login last_updated_well_known
+docker exec -u www-data <container-id> php occ config:app:delete oidc_login last_updated_jwks
 ```
 
-### Creating Secrets
+## How do I enable multiple SSO login buttons?
 
-Set the secrets. The usual way to create a secret is:
+We've been able to get this setup by using the [social login](https://apps.nextcloud.com/apps/sociallogin) plugin.
 
-```
-printf "SECRET_HERE" | docker secret create SECRET_NAME -
+If using Keycloak, you'll want to do [this trick](https://janikvonrotz.ch/2020/10/20/openid-connect-with-nextcloud-and-keycloak/) also.
+
+## How can I customise the CSS?
+
+There is some basic stuff in the admin settings.
+
+To go a little deeper, you can use [this handy app](https://apps.nextcloud.com/apps/theming_customcss).
+
+Here is an example CSS config which hides the local login and makes space for a central image:
+
+```css
+#body-login .wrapper main form[name="login"],
+#body-login .wrapper main form[name="login"] ~ a {
+  display: none;
+}
+
+#body-login .logo {
+  visibility: hidden;
+}
+
+#body-login #alternative-logins a.button[href*="oidc"] {
+  background: #233b4a;
+  color: #fff;
+  transition: all 0.2s ease-in-out;
+}
+#body-login #alternative-logins a.button[href*="oidc"]:hover {
+  background: linear-gradient(-35deg, #233b4a 40%, #486c83 100%);
+}
+
+#body-login #alternative-logins a.button[href*="/sociallogin/oauth/google"] {
+  border: 0;
+  color: #db4437 !important;
+  background-color: #fff;
+}
+
+#body-login
+  #alternative-logins
+  a.button[href*="/sociallogin/oauth/google"]::before {
+  width: 25px;
+  background-color: #db4437;
+  border-radius: 100%;
+  background-size: 60%;
+  background-position: center;
+  height: 25px;
+  vertical-align: middle;
+  margin-right: 4px;
+}
+
+#body-login main {
+  padding: 50vh 0 0 0;
+}
+
+#body-login a[href*="#body-login"] {
+  visibility: hidden;
+}
+
+#body-login footer a,
+#body-login footer p {
+  color: #233b4a;
+}
+
+#body-login footer a:hover {
+  color: #fff;
+}
+
+#body-login footer p.info {
+  text-shadow: none;
+}
 ```
 
-The required secrets are:
+[nextcloud-docker]: https://hub.docker.com/_/nextcloud/
+[`abra`]: https://git.autonomic.zone/autonomic-cooperative/abra
+[`coop-cloud/traefik`]: https://git.autonomic.zone/coop-cloud/traefik
 
-- `db_password`: The MariaDB database password for the `nextcloud` user.
-- `admin_password`: The Nextcloud admin user's password.
-- `smtp_password`: The SMTP password for sending emails.
-- `elasticsearch_password`: The Elasticsearch password.
-- `db_root_password`: The MariaDB root user password.
+## Using [`previewgenerator`](https://github.com/nextcloud/previewgenerator) app
 
-We can generate these secrets using `openssl rand -base64 32` or similar.
+> Beware, this appp has been known to not work...
+
+After you install, enable etc. then you need to run the generation (**warning**: it can take a long time!):
 
 ```
-openssl rand -base64 32 | docker secret create db_password -
-openssl rand -base64 32 | docker secret create admin_password -
-openssl rand -base64 32 | docker secret create smtp_password -
-openssl rand -base64 32 | docker secret create elasticsearch_password -
-openssl rand -base64 32 | docker secret create db_root_password -
+abra app run <domain> app bash -u www-data
+./occ preview:generate-all
 ```
 
-### Deploying the App
-
-Deploy using the `-c` flag to specify one or multiple compose files.
+To set up the cron to run again, there is [no clear solution in the context of
+containers](https://github.com/nextcloud/previewgenerator/issues/1). So, a
+pretty dodgy hack is to run it from the system directly:
 
 ```
-docker stack deploy nextcloud --detach=true -c compose.yaml -c compose.mariadb.yaml -c compose.smtp.yaml -c compose.fulltextsearch.yaml
+root@foo.com /etc/cron.hourly $ cat foo-com-preview-generate 
+#!/bin/bash
+
+docker exec -u www-data $(docker ps -f name=foo_com_app -q) ./occ preview:pre-generate
 ```
 
-### Enabling Full Text Search
-
-To enable full text search, we first set up some environment variables for running commands inside the app and database containers:
-
-```
-export NC_APP="docker exec -u www-data -it $(docker ps --filter name=${STACK_NAME}_app --format '{{.ID}}' | head -n 1)"
-export NC_DB="docker exec -it $(docker ps --filter name=${STACK_NAME}_db --format '{{.ID}}' | head -n 1)"
-```
-
-Next, run the following commands to install and configure the necessary Nextcloud apps for full text search with Elasticsearch:
-
-```
-$NC_APP php /var/www/html/occ app:install fulltextsearch
-$NC_APP php /var/www/html/occ app:install fulltextsearch_elasticsearch
-$NC_APP php /var/www/html/occ app:install files_fulltextsearch
-
-$NC_APP php /var/www/html/occ config:app:set fulltextsearch search_platform --value="OCA\\FullTextSearch_Elasticsearch\\Platform\\ElasticSearchPlatform"
-$NC_APP php /var/www/html/occ config:app:set fulltextsearch_elasticsearch elastic_host --value="http://elastic:$(cat /run/secrets/elasticsearch_password)@elasticsearch:9200/"
-$NC_APP php /var/www/html/occ config:app:set fulltextsearch_elasticsearch elastic_index --value="nextcloud"
-$NC_APP php /var/www/html/occ config:app:set files_fulltextsearch files_local --value="1"
-```
-
-Verify the setup by running:
-
-```
-$NC_APP php /var/www/html/occ config:list files_fulltextsearch
-```
-
-Then, check for connectivity with Elasticsearch:
-
-```
-$NC_APP php /var/www/html/occ fulltextsearch:test
-```
-
-Manually build the search index:
-
-```
-$NC_APP php /var/www/html/occ fulltextsearch:index
-```
-
-If you get “Index is already running”, clear the ticker table in the database:
-
-```
-$NC_DB sh -c 'echo "delete from oc_fulltextsearch_ticks;" | mariadb -u root -p$(cat /run/secrets/db_root_password) nextcloud'
-```
+This app will improve performance of image browsing at the cost of storage space.
