GitHub.com: GIT Directory-Based Configs

About

So, you are a proud OpenSource developer and work for a company using GitHub.com for GIT repository hosting?

While SSH auth to GitHub.com is based on public keys and it automatically chooses the right account you have to take care when you quickly clone a repository, change something and whoops your company has your private email address or hacker pseudo within their repository.

The scenario we are speaking about looks like following:

# SSH to AWS EC2 instances using peco and awless
#
# - Generate a cache of AWS instances 
# - Open peco to select one or more server and either open ssh or tmux-css
# - Does not use `awless ssh` since prefererence on ‘security by obscurity’

Snowflake Reconnaissance

About

This page will assist you in retrieving important information from so called Snowflake Server which exist in your infrastructure unversioned and with unknown status. The basic idea is that system files in a modern system are under packages control, which enables us to do following:

• verify files and look for changed and missing files and other diversions
• identify files that do not belong to the system
• enable you to do a proper backup of the important (changed) files only
• and effectively transform a snowflake to become part of your fleet (IaC)

Myth about associative arrays in BASH

To be clear: It's possible to pass associative arrays in BASH.

TL;DR you probably didn't RTFM so please njoy following session!

Pass an associative array the correct-BASH way

-- This is a sample custom writer for pandoc.  It produces output
-- that is very similar to that of pandoc's HTML writer.
-- There is one new feature: code blocks marked with class 'dot'
-- are piped through graphviz and images are included in the HTML
-- output using 'data:' URLs.

-- Invoke with: pandoc -t sample.lua

In response to: https://blog.codecentric.de/en/2021/03/github-actions-nextgen-cicd/

GitLab CI has templates you could use. Only bad thing is they did is they way they launch their job containers (defaulting to BASH/SH interpreter and preprocessing script section). This is a bit limiting in using custom containers for integration. But you can do as well.

GitHub actions do have their action params which make them nice for for validation, also they focused more on the API but I do see actions also as way of monetizing integration which is the cloud's OpenSource business model.

And here we are with Tekton or even AWS CodePipeline which could be more seen as CloudPipeline. The questions is how a CICD becomes cloud native? And one part of the answer is integration with Cloud and Services API. That's more about the paradigm shift of the "third" wave.

Also a simple CICD became now a build platform that integrate into the layers of the cloud, mainly orchestrators and solve the problems of how artifacts and data fl
