Git - why you shouldn't use long-lived feature branches

* Environment Branches may be one of the few exceptions but requires workflow discipline.

AWS Web Traffic Classic

Azure Active Directory Single Sign-On

I've administered Azure Active Directory at a couple of companies and integrated a variety of applications including GitHub Enterprise Cloud, AWS IAM Identity Center (formerly AWS SSO), Jenkins, ArgoCD, Keycloak, Hubspot etc using the typical OIDC or SAML integration mechanisms.

Jenkins CI/CD on Kubernetes

A production Jenkins on Kubernetes I built for a client with auto-spawning agents for horizontal scaling and integration with Docker, SonarQube, Clair, Grype and Trivy for code & container scanning.

OpenTSDB on Kubernetes and HBase

A high scale production OpenTSDB replatform I did to Kubernetes for a client, ingesting 9 billion data points per day and serving 3 million queries per day.

I also had to do advanced performance tuning of their production HBase cluster which was suffering from frequent outages at this scale due to being set up by a non-SME on the wrong hardware (I had to make do with the existing hardware of course).

This was the second client I did in-depth performance tuning of HBase for - I've published a selection of useful HBase tools - see hbase_*.py and opentsdb_*.py in HariSekhon/DevOps-Python-tools.

Devs Test in Production

Iirc I created and stuck this meme pic of The Most Interesting Man in the World on the wall of my tech dept back in 2011 while leading the infra team of an internet Ad Tech company doing several production releases a day. We literally did test in production using a small fraction of live internet traffic via canary deployments.

The Danger of Testing Ideas in Production

I may have gone overboard and done so many Diagrams-as-Code I'm starting to see life this way...

karl_marx_test_ideas_in_production.d2

Git - Environment Branches

At least they don't only test in Production!

Another internet facing client refused to use tagging because they didn't want to have to think up version or release numbers for their website releases.

Not everybody likes environment branches, but they worked in production for over 2 years and they are easy to use.

Also, contrary to some naysayers it's quite easy to diff environment branches as everything should be in Git, so you can get a very quick and easy difference between your environments in a single git diff command. It's also easy to automate backporting hotfixes to lower environments:

%%{ init: {
        "logLevel": "debug",
        "theme": "dark",
        "gitGraph": {
            "mainBranchName": "dev"
        },
        "themeVariables": {
            "git0": "red",
            "git1": "blue ",
            "git2": "green",
            "gitInv0": "#FFFFFF",
            "gitBranchLabel0": "#FFFFFF",
            "commitLabelColor": "#FFFFFF"

    checkout dev
    commit id: "commit 5"

    checkout staging
    commit id: "QA fix 3 "

    %% new MermaidJS comment format
    %% checkout production
    %% commit id: "commit 5  "

    checkout dev
    commit id: "commit 6"

    checkout staging

    checkout production
    merge staging id: "fast-forward merge 3 " tag: "v2023.3 Release (CI/CD)"

Note: I did eventually move this client to tagged releases using YYYY.NN release format, just incrementing NN which is a no brainer (githubNextRelease.groovy). It turns out the developers had eventually started using releases in Jira labelled as YYYY.NN to track which tickets were going into which production deployment, so when I pushed for this, it made sense to them finally as not being too great an inconvenience! It's also easy to automate by creating GitHub Releases in Jenkins (githubCreateRelease.groovy).

LucidChart - GCP Architecture

A sample architecture I did for a client for us to talk through, which was similar to what they had in mind (I won the gig).

This is the only diagram not as code (here for historical interest). I would embed the interactive live diagram but GitHub markdown doesn't allow HTML iframes so this is the png.

Build from Source

Install D2, Graphviz, Python3 and 'diagrams' pip module:

git clone https://github.com/HariSekhon/Diagrams-as-Code diagrams

cd diagrams

make install

Create all the .png and .svg diagrams in the images/ dir:

make

Generate only the D2 svg diagrams:

make d2

Generate only the Python png diagrams:

make py

Create any single D2 diagram by running the d2 script file:

./jenkins_kubernetes_docker.d2

Create any single Python diagram and have it open automatically by running the python script file:

./gcp_cloudflare_web_architecture_gke.py

Templates

The templates/diagram.d2 and templates/diagram.py show the basics of each language.

They are a good starting point for creating your own diagrams, and come pre-loaded with many useful icons, links to docs and links to icon sets.
