@hungrymonkey Did you manage to deploy Rocket.Chat?

I'm getting an error when executing MongoDb replica Set:

{"msg": "The conditional check '('ok' in (replSet_result.stdout | from_json))' failed. The error was: No JSON object could be decoded"}

I gave up and deployed the snap releases. This ansible does not seem to be maintained. You can peak at the effort to deploy the snapd below

Rocket Chat Server

Home server URL

rocketchat.domain.com

Install

1. Start Ubuntu AWS VM with Open Ports
   • 80 (TCP HTTP)
   • 443 (TCP HTTPS)
2. Install Rocket Snap
   • sudo snap install rocketchat-server --channel=3.x/stable
3. Setup Lets Encrypt
   • sudo snap set rocketchat-server caddy-url=https://rocketchat.domain.com
   • sudo snap set rocketchat-server caddy=enable
   • sudo snap set rocketchat-server https=enable
   • sudo snap run rocketchat-server.initcaddy
4. Start Server
   • sudo systemctl restart snap.rocketchat-server.rocketchat-server.service
   • sudo systemctl restart snap.rocketchat-server.rocketchat-caddy.service
5. Check Status
   • sudo service snap.rocketchat-server.rocketchat-server status
   • sudo service snap.rocketchat-server.rocketchat-mongo status
   • sudo service snap.rocketchat-server.rocketchat-caddy status

Deploy Automated Backups

1. Move systemd/myrocketchat-backup.timer and systemd/myrocketchat-backup.service to /etc/systemd/system/
   • /etc/systemd/system/myrocketchat-backup.timer
   • /etc/systemd/system/myrocketchat-backup.service
2. Enable the timer
   • sudo systemctl enable myrocketchat-backup.timer
3. Start the timer
   • sudo systemctl start myrocketchat-backup.timer

Helpful tips

1. View Logs

sudo journalctl -f -u snap.rocketchat-server.rocketchat-server
sudo journalctl -f -u snap.rocketchat-server.rocketchat-mongo
sudo journalctl -f -u snap.rocketchat-server.rocketchat-caddy

Common Errors

1. Google Oauth2 - redirect_uri_mismatch

• In the Authorized redirect URIs field, add both urls

  ```
  https://rocketchat.domain.com/_oauth/google
  https://rocketchat.domain.com/_oauth/google?close
  ```

## Issue 1
## Snap has to be run with sudo
## permanently dropping privilege did not work: File exists

## Issue 2
## rm glob * become expanded when the service starts
## /var/snap/rocketchat-server/common/backup/ will be empty
## Moved the command to exec start so the glob will be
## populated properly
