Meteor 3 WeKan: Hosting many WeKan kanban, websites, etc

Note: Only Oplog sockjs works with multitenancy, see multitenancy.md.

Migrating from Parallel Snap setup, because snap set wekan root-url=... etc commands are slow to run, and did not get Parallel Snap working properly yet.

caddy proxy: Let's Encrypt and CloudFlare TLS to localhost http ports

  |==> Many Parallel WeKan Snap Containers at different ports,
  |    each Container with it's own Node.js/MongoDB
  |==> Sandstorm, many websites with WordPress and Hackers CMS
  |==> PHP/MySQL WordPress     (example)
  |==> PHP/MySQL Hesk Helpdesk (example)
  |==> PHP/MySQL Kanboard      (example)
  |==> Static websites         (example)

To this Docker setup:

caddy proxy: Let's Encrypt and CloudFlare TLS to localhost http ports
  |
  |==> Many Docker Meteor 3 WeKan Node.js Containers,
  |    Uses changeStreams and DDP_TRANSPORT=uws
  |     |
  |     |=> One MongoDB without container,
  |         always requires password to login,
  |         for admin and each other users,
  |         each user has it's own database, username and password

Save all Parallel Snap container settings with:

snap-save-settings.sh

For setting up MongoDB etc, use examples at apt directory.

MongoDB config /etc/mongod.conf is at mongo directory.

Create MongoDB key:

./keys.sh

Adding new user, it saves MongoDB connection string to username.txt:

./1createdb.sh username

Same username.txt is used when login to database, backup, restore, files transfer, etc.

You can connect to database:

./sh.sh username

Or sometime make Backup to backup/username/YYYY-MM-DD_HH-MM-SS/

./backup.sh username

Create docker-compose.yml to restore/username/

./2docker.sh username

Edit docker-compose.yml and start Docker container:

cd restore/username/

nano docker-compose.yml

docker compose up -d

Restore database

./3restoredb.sh username

Transfer attachments and avatars from Snap server to Docker server:

./4files.sh username

Restart Docker container:

cd restore/username/

docker compose stop

docker compose start

Upgrade WeKan from old version to new version, for example:

./update-wekan-version.sh 9.10 9.11"
