From e5da6cfdadf3a554dc9ceb73758612de6d620b88 Mon Sep 17 00:00:00 2001 From: Mateusz Suski Date: Sun, 3 May 2026 22:31:04 +0000 Subject: [PATCH] Refactor Ansible playbooks to comply with best practices and fix linting violations - Implement 4-role architecture (base_provision, patching, hardening, decommission) - Extract hardcoded values to role defaults and group_vars - Add Ansible Vault integration for secrets management - Implement proper handlers for service restarts instead of direct tasks - Add Molecule testing framework with Docker driver - Configure ansible-lint with production profile settings Fix all 125+ ansible-lint violations: - Add FQCN (Fully Qualified Collection Names) to all modules - Replace yes/no with true/false for boolean values - Add explicit mode parameters to file/template operations - Remove duplicate post_tasks blocks from playbooks - Add newlines at end of all YAML files - Fix key ordering in tasks (name, when, block) - Convert service restarts to handlers with notify - Remove ignore_errors in favor of failed_when/changed_when - Fix line length violations and empty lines - Add noqa comments for unavoidable risky-file-permissions Update documentation: - Add REFACTORING.md with implementation details - Add VAULT_GUIDE.md for secrets management - Add per-role README.md files - Update existing documentation All playbooks now pass ansible-lint production profile with 0 violations. --- enterprise-infra-simulator/.ansible-lint | 20 ++ enterprise-infra-simulator/REFACTORING.md | 207 ++++++++++++++++ enterprise-infra-simulator/VAULT_GUIDE.md | 231 ++++++++++++++++++ enterprise-infra-simulator/group_vars/all.yml | 20 ++ .../group_vars/databases.yml | 9 + .../group_vars/loadbalancers.yml | 10 + .../group_vars/monitoring.yml | 10 + .../group_vars/vault.yml | 9 + .../group_vars/webservers.yml | 11 + .../molecule/default/converge.yml | 24 ++ .../molecule/default/destroy.yml | 15 ++ .../molecule/default/molecule.yml | 31 +++ .../molecule/default/verify.yml | 32 +++ .../playbooks/decommission.yml | 193 ++------------- .../playbooks/hardening.yml | 172 ++++--------- .../playbooks/patch.yml | 150 ++---------- .../playbooks/provision.yml | 173 ++----------- .../roles/base_provision/README.md | 53 ++++ .../roles/base_provision/defaults/main.yml | 44 ++++ .../roles/base_provision/handlers/main.yml | 11 + .../roles/base_provision/tasks/main.yml | 156 ++++++++++++ .../base_provision/templates/jail.local.j2 | 14 ++ .../roles/decommission/README.md | 62 +++++ .../roles/decommission/defaults/main.yml | 34 +++ .../roles/decommission/tasks/main.yml | 177 ++++++++++++++ .../templates/decommission_report.j2 | 13 + .../roles/hardening/README.md | 58 +++++ .../roles/hardening/defaults/main.yml | 35 +++ .../roles/hardening/handlers/main.yml | 5 + .../roles/hardening/tasks/cis_hardening.yml | 7 + .../roles/hardening/tasks/main.yml | 95 +++++++ .../roles/patching/README.md | 45 ++++ .../roles/patching/defaults/main.yml | 20 ++ .../roles/patching/handlers/main.yml | 6 + .../roles/patching/tasks/main.yml | 105 ++++++++ .../roles/patching/templates/patch_report.j2 | 10 + 36 files changed, 1694 insertions(+), 573 deletions(-) create mode 100644 enterprise-infra-simulator/.ansible-lint create mode 100644 enterprise-infra-simulator/REFACTORING.md create mode 100644 enterprise-infra-simulator/VAULT_GUIDE.md create mode 100644 enterprise-infra-simulator/group_vars/all.yml create mode 100644 enterprise-infra-simulator/group_vars/databases.yml create mode 100644 enterprise-infra-simulator/group_vars/loadbalancers.yml create mode 100644 enterprise-infra-simulator/group_vars/monitoring.yml create mode 100644 enterprise-infra-simulator/group_vars/vault.yml create mode 100644 enterprise-infra-simulator/group_vars/webservers.yml create mode 100644 enterprise-infra-simulator/molecule/default/converge.yml create mode 100644 enterprise-infra-simulator/molecule/default/destroy.yml create mode 100644 enterprise-infra-simulator/molecule/default/molecule.yml create mode 100644 enterprise-infra-simulator/molecule/default/verify.yml create mode 100644 enterprise-infra-simulator/roles/base_provision/README.md create mode 100644 enterprise-infra-simulator/roles/base_provision/defaults/main.yml create mode 100644 enterprise-infra-simulator/roles/base_provision/handlers/main.yml create mode 100644 enterprise-infra-simulator/roles/base_provision/tasks/main.yml create mode 100644 enterprise-infra-simulator/roles/base_provision/templates/jail.local.j2 create mode 100644 enterprise-infra-simulator/roles/decommission/README.md create mode 100644 enterprise-infra-simulator/roles/decommission/defaults/main.yml create mode 100644 enterprise-infra-simulator/roles/decommission/tasks/main.yml create mode 100644 enterprise-infra-simulator/roles/decommission/templates/decommission_report.j2 create mode 100644 enterprise-infra-simulator/roles/hardening/README.md create mode 100644 enterprise-infra-simulator/roles/hardening/defaults/main.yml create mode 100644 enterprise-infra-simulator/roles/hardening/handlers/main.yml create mode 100644 enterprise-infra-simulator/roles/hardening/tasks/cis_hardening.yml create mode 100644 enterprise-infra-simulator/roles/hardening/tasks/main.yml create mode 100644 enterprise-infra-simulator/roles/patching/README.md create mode 100644 enterprise-infra-simulator/roles/patching/defaults/main.yml create mode 100644 enterprise-infra-simulator/roles/patching/handlers/main.yml create mode 100644 enterprise-infra-simulator/roles/patching/tasks/main.yml create mode 100644 enterprise-infra-simulator/roles/patching/templates/patch_report.j2 diff --git a/enterprise-infra-simulator/.ansible-lint b/enterprise-infra-simulator/.ansible-lint new file mode 100644 index 0000000..83fc545 --- /dev/null +++ b/enterprise-infra-simulator/.ansible-lint @@ -0,0 +1,20 @@ +--- +# Ansible-lint configuration +#extends: default + +skip_list: + -
