Guide to User-Centric CRUD using Express & Mongoose

Intro

Typically, logged in users interact with an application that results in data being created, updated and deleted.

In almost every case, the application's code will need to ensure that the logged in user can only update/delete data created by them, not the data of other users.

Start-of-Day Reflections

I am grateful for...

What would make today great?

Rancher cluster on k3os

Goal

Install rancher on k3os with centralized datastore on mysql cluster.

Environment

Host: Ubuntu 18.04.4 Desktop (32gb ram 4 cpu)
Virtualisation: kvm/qemu (virtual machine manager)
Local network: 192.168.0.0/16
- Gateway: 192.168.0.1

Proxmox PVE Host Config Backup Script

This script can be used to backup essential configuration files from the Proxmox Virtual Enivronment (PVE) host.

The script will create backups using tar with specified backup prefix and date and time stamp in the file name. Script will also delete backups that are older then number of days specified.

Create backup script file

To create backup script that will be executed every day we can create backup script in /etc/cron.daily/ folder. We need to make it writeable by root (creator) only, but readable and executable by everyone:

touch /etc/cron.daily/pvehost-backup

Install Proxmox and a RancherOS VM with Portainer to manage docker containers

WARNING MAY BE INCORRECT AND INCOMPLETE, USE AT YOUR OWN RISK

I have tried this setup and although it works and may be good for ceratin circumstances I would advise using ubuntu as the base with docker, docker-compose, and portainer. https://gist.github.com/mow4cash/626275e095f7f90898944a85d66b3be6
