I Wrote a Docker Book — Here's Why

I never got through most technical books. Too much theory. Too many words. Not enough action.

So I wrote the book I wished existed — practical, concise, and straight to the point. Just enough explanation to get things done.

Why This Book?

Over the past 5 years, I've worked with Docker in training rooms, client environments, and real production deployments in Singapore — teaching engineers, advising on architecture, and rolling it out on actual infrastructure.

Docker comes up everywhere, and so does the same question: where do I start?

The problem isn't capability. It's always the same thing: people get lost in the theory before they ever run a single container. They read about namespaces and cgroups and layer caches, and by the time they get to an actual command, they've lost the thread.

So I started keeping notes — just the practical bits. The commands that actually matter. The patterns that show up again and again in real deployments.

During Chinese New Year 2026, I finally sat down and turned those notes into this book.

What's Inside

"Levelling Up with Docker: A Practical Guide to Containers" covers:

  • Rootless Docker installation (Ubuntu, RHEL, SLES)
  • Running containers and managing images
  • Container networking (bridge, host, overlay)
  • Volumes and persistent data
  • Docker Compose for multi-service applications
  • Private container registry setup
  • Troubleshooting playbook

14 chapters. Answer sheet included. About 2-3 hours to complete.

Who This Book Is For

This book is for you if:

  • You're a Linux admin who needs to learn Docker fast
  • You prefer hands-on over theory
  • You want to deploy containers with confidence
  • You're tired of tutorials that skip the "why"

This book is NOT for you if:

  • You want deep dives into container internals
  • You're looking for Kubernetes orchestration (that's a different book)
  • You prefer lengthy explanations and background theory

How to Get It

The book is available on Amazon Kindle now:

📚 Get "Levelling Up with Docker" on Amazon

The paperback edition is pending approval and will be available soon.

What's Next

This is the first Docker-related post on FOSSTECH NOTES. I'll be sharing more Docker tutorials, tips, and troubleshooting guides in the coming weeks.

If you have questions about the book or Docker in general, feel free to reach out via LinkedIn or X/Twitter.

SLES 15 LVM + XFS Without Separate /boot Partition

Image
GRUB2 allow booting from LVM partition, however I haven't see any documentation on how to setup SLES 15 using LVM + XFS root partition without separate /boot partition. You can even put /boot as one of the logical volume. When separate /boot partition is not created, we will need to create small partition with BIOS boot flag and once this BIOS boot partition is created, you can setup the remaining disk as LVM partition and setup your volume group and logical volumes as usual.    During the installation, choose "Expert Partitioner" > "Start with Existing Partitions". Select your disk and "Create New Partition Table" > "GPT" Select "Partitions" tab and choose "Add Partition" Choose "Custom Size" then enter "8 MiB" as the size. The Role of this partition should be "Raw Volume (unformatted)" Select BIOS Boot as Partition ID Create another partition as LVM pa...

pfSense and scp

pfSense and scp doesn't play nice. When you try to scp to admin@pfsense.hostname you will likely encounter the error " Illegal option -[X] " The solution to this is rather simple too, when running scp to pfSense, just use the root account.  Cheers

ldapsearch over ssl (ldaps) to Active Directory

In order for Linux to perform ldapsearch over ssl, you need to import Active Directory CA certificate. On ActiveDirectory run the following command: > certutil -ca.cert adca.der Copy adca.der into the Linux server and convert the cert into Linux friendly cert #  openssl x509 -inform DER -in adca.der -out adca.crt Move the file into the default ca-trust directory # cp adca.crt /etc/pki/ca-trust/source/anchors/ # update-ca-trust You are ready to run ldapsearch over ssl to Active Directory Assuming you ad server is adsvr.fosstech.biz for fosstech.biz domain, you can run ldapsearch as follow # ldapsearch -x -W -H ldaps://adsvr.fosstech.biz  -D "administrator@fosstech.biz" -b "dc=fosstech,dc=biz" * Cheers!!! 📚 Want to Learn Docker?
