Free Docker first contact
Build the first Docker mental model, read engine evidence, run a named container, inspect it, read logs, and clean up.
No credit card required. The chapter includes 9 focused lessons.
Before you start
No Docker experience is required. Basic command-line familiarity is helpful.
The chapter begins inside the same reading and practice format used by the paid course. It is not a shortened product tour.
How it works
Read the system. Do the work. Prove the result.
The lesson stays beside the workspace so the explanation and the evidence remain connected.
- 1
Investigate
Read the symptoms, vocabulary, and exact question before making a change.
- 2
Repair
Run a command, edit a file, or inspect state in an isolated practice workspace.
- 3
Understand
Clear a proof checkpoint and connect the evidence to the decision that worked.
Ready to practice
Open the chapter and produce the first proof.
The workspace explains the requested result, lets you act, and marks the checkpoint only after the relevant evidence is present.
