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

1) Install WeKan exactly like this

Use all settings and config files at this page and subdirectories.

2) Backup your previous WeKan server

See backup scripts etc, mongodump and files directory

3) Restore to your new WeKan install

Use restore scripts to mongorestore and restore files (attachments and avatars)

4) Move all files from MongoDB to filesystem

This will speed up loading attachments a lot.

1. Admin Panel / Attachments
2. Default Storage: Filesystem
3. Move Files: From MongoDB CollectionFS to Filesystem
4. Move Files: From MongoDB Meteor-Files to Filesystem
5. MongoDB GridFS Storage: Compact Database (this will make MongoDB disk usage smaller)

Migrating from Snap to Docker

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

  |==> Sandstorm, many websites with WordPress and Hackers CMS

  |==> PHP/MySQL Hesk Helpdesk (example)
  |==> PHP/MySQL Kanboard      (example)
  |==> Static websites         (example)

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

1. 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

2. 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

3. Restore database

./3restoredb.sh username

4. Transfer attachments and avatars from Snap server to Docker server:

./4files.sh username

5. Restart Docker container:

cd restore/username/

docker compose stop

docker compose start

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

./update-wekan-version.sh 9.10 9.11
