Principles of Adult Behavior

  1. Be patient. No matter what.
  2. Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
  3. Never assume the motives of others are, to them, less noble than yours are to you.
  4. Expand your sense of the possible.
  5. Don’t trouble yourself with matters you truly cannot change.
  6. Expect no more of anyone than you can deliver yourself.
  7. Tolerate ambiguity.
  8. Laugh at yourself frequently.

Laravel - Eloquent: Cascading delete, forceDelete and restore

If you want to delete a model with related models you can use Laravel model events. There is also a special case if your models cascade.

Lets say you have Folder and File Eloquent models that are related and use SoftDeletes trait and when you delete a folder you also want to delete files in folder and all subfolders with files.

In the boot method or Folder model you catch delete and restore events (actually deleting and restoring events that trigger before restoring or deleting happens). You can delete/restore all files in folder you're deleting/restoring with $folder->files()->delete(); and $folder->files()->withTrashed()->restore();.

Folders on the other hand cascade (folder in a folder in a folder) and because events do not trigger if you don't pull the models (->get() method), the model events won't trigger for subfolders. That's why you need to pull the folders and iterate trough them (->each() method) and delete/restore them.

You could use database CASCADE feature but that does

#!/bin/bash
# This is a script to send a notification from OTRS to Mattermost.
# Create a new Generic Agent and select "TicketCreate" under event based events.
# Finally, put in the path to the script into the command box.
# Of course you could use it for different notifications, but OTRS is only giving the ticket number and id to the script.

Provisioning and usage of unprivileged LXC containers via indirect login or script #blog

Provisioning and usage of unprivileged LXC containers via indirect login or script

As I've discovered, managing LXC containers is fairly straightforward, but when building out a system for provisioning out user maintained instances of NodeBB, it was imperative that unprivileged LXC containers were used, so that in the event of shell breakout from NodeBB followed by privilege escalation of the saas user, the root user in the LXC container would only be an unprivileged user on the host machine.

During the course of development, I ran into numerous blockers when it came to managing LXC containers in unexpected circumstances. Namely:

  • Using LXC in a subshell is not directly supported. This usually happens under one of the following two circumstances:
    • After switching users via su or executing lxc-* commands as another user via sudo
    • Executing lxc-* commands via a program, application, or script. In my case, a Node.js application.
