Ubuntu 22.04 LTS With Boot-Time Mounted F2FS Root Partition

Put "/" at the end for src. and dest. directory for "rsync" to do proper copy!

Original partition structure

"/dev/nvme0n1p1" => /boot/efi (fat32)

"/dev/nvme0n1p2" => /boot (ext4)

"/dev/nvme0n1p3/" => / (f2fs)

The issue

It happened after secrets file was lost during GitLab upgrade.

The case described in documentation When the secrets file is lost

But not completely clear.

From log file /var/log/gitlab/gitlab-rails/production.log:

GKE ingress in a nutshell

https://medium.com/google-cloud/ingress-in-google-kubernetes-products-f22ded21f4ed

Solution #1 (ManagedCertificate CRD in GKE)

GKE with Google-managed SSL certificates
- Use ManagedCertificate CRD to create a object.
- Associate the ManagedCertificate object to an Ingress by adding an annotation networking.gke.io/managed-certificates to the Ingress. This annotation is a comma-separated list of ManagedCertificate resources, cert1,cert2,cert3 for example.

Solution #2 (Google Cloud SSL Certificate)

– Filtering AWS resources with Boto3

This post will be updated frequently when as I learn more about how to filter AWS resources using Boto3 library.

Filtering VPCs by tags

README

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

	# Client configs, 16.04,
	script-security 2
	up /etc/openvpn/update-resolv-conf
	down /etc/openvpn/update-resolv-conf

	# network manager, 16.04, install below package to enable import openvpn client configs
	sudo apt install network-manager-openvpn-gnome


	# Client configs, 18.04/18.10

	#!/bin/bash

	# This script cleans all cache for Microsoft Teams on Linux
	# Tested on Ubuntu-like, Debian by @necrifede, Arch Linux by @lucas-dclrcq and Manjaro with flatpak by @danie1k. Feel free to test/use in other distributions.
	# Tested Teams via snap package.
	# Tested Teams via flatpak package.
	#
	# How to use in terminal:
	# ./clear_cache_MS_Teams.sh ( deb-stable \| deb-insider \| snap \| flatpak )
	# or
