Learn Docker with a visual, interactive playground.
Inspired by the tactile clarity of LearnGitBranching. Run real container commands, bridge virtual networks, build immutable image layers, and solve break-fix puzzles — entirely in your browser.
Deterministic AST parser and state machine executes container commands in 0ms without virtualization lag.
Understand DNS 127.0.0.11 routing, bridge isolation, and port forwarding through live interactive diagrams.
Tackle realistic production failure modes: crash loops, port collisions, and orphaned networks.
