Molecule for Testing Network Automation Ansible Projects
summary
Molecule runs Ansible playbooks against ephemeral targets: this demo boots a Cisco IOS container as a mock router, uses the delegated driver to SSH into it, parses "show ip interface brief" with TextFSM parsing, and indexes results into Elasticsearch. Molecule linting catches syntax errors, the idempotence check replays tasks, and the verify step asserts documents exist (an intentional mismatch fails). It works end-to-end but consumes significant CPU and disk.
