Building the skill.
WHAT TO LEARN FIRST
What a container actually is: a process, isolated.
WHY THAT FIRST
Most confusion comes from imagining a virtual machine.
WHAT TO PRACTISE NEXT
Running images Building your own Mounting volumes Networking two containers together
WHAT TO BUILD
Something real: an application and its database, running together.
WHY REAL
It surfaces persistence, configuration and networking at once.
WHAT TO LEARN AFTER THAT
Compose, for several containers on one host.
WHAT TO DELAY
Orchestration, until you have the problems it solves.
WHY
Learning it first teaches machinery without context.
WHAT TO PRACTISE DELIBERATELY
Killing a container and watching what happens Filling a disk Exceeding a memory limit Breaking a probe
WHY FAILURE PRACTICE
Diagnosis is the skill, and it cannot be read.
WHAT TO LEARN TO READ
Events, before logs.
WHY
They explain scheduling and mounting failures logs never show.
WHAT SEPARATES COMPETENCE
Knowing what a container can and cannot do Knowing when not to use orchestration
WHAT TO AVOID
Copying manifests without understanding them.
WHAT TO DOCUMENT
What you had to look up twice.
