Docker Ep 5: Docker Compose for Local Microservices

Sun, 09 Aug 2026 16:40:00 +0000

Running 10 docker run commands manually with complex flags is tedious and error-prone. Docker Compose allows you to define and run your entire multi-container infrastructure declaratively in a single YAML file.

Docker Ep 4: Volumes & Data Persistence

Sun, 09 Aug 2026 16:35:00 +0000

By default, all files created inside a container are stored on a writable container layer. When that container is deleted, the data is destroyed. Docker Volumes solve this by storing data outside the container filesystem.

Docker Ep 3: Docker Networking Deep Dive

Sun, 09 Aug 2026 16:30:00 +0000

How do two containers on the same host talk to each other without exposing ports to the public internet? Docker uses Linux virtual network interfaces (veth pairs) connected to a software bridge.

Docker Ep 2: Writing Production Dockerfiles

Sun, 09 Aug 2026 16:25:00 +0000

Shipping a 1GB Docker image containing compilers, debuggers, and build tools to production is a security nightmare. Multi-Stage Builds allow you to separate the build environment from the tiny runtime container.

Docker Ep 1: Architecture & Container Primitives

Containers do not exist as physical entities inside the Linux kernel. A “container” is simply a standard Linux process isolated via Namespaces, throttled by cgroups, and mounted on an Overlay2 union filesystem.
