Changes: **Docker Compose Integration:** - Extended DockerComposeContext with grafana_config field and with_grafana() builder - Extended EnvContext with GrafanaServiceConfig and with_grafana() method - Added conditional Grafana service to docker-compose.yml.tera template - Image: grafana/grafana:11.4.0 - Port mapping: 3100:3000 - Named volume: grafana_data - Depends on: prometheus - Added Grafana environment variables to .env.tera template - GF_SECURITY_ADMIN_USER - GF_SECURITY_ADMIN_PASSWORD **Environment Model:** - Added grafana_config() getter methods to Environment and EnvironmentContext - Re-exported GrafanaConfig from domain::environment module **Rendering Step:** - Extended RenderDockerComposeTemplatesStep with apply_grafana_config() method - Extended with apply_grafana_env_context() to expose secrets for templates - Properly exposes Password secrets for Tera template rendering **Code Quality:** - Refactored long namespace paths to use proper imports at module top - All 1554 unit tests passing - E2E infrastructure and deployment tests passing **Issue Progress:** - Updated issue checklist marking Phase 1 and Phase 2 tasks complete - Phase 3 (Firewall & Testing) remains pending Phase 2 follows the established pattern from Prometheus slice implementation and maintains consistency with the project's architecture and conventions. --- .../246-grafana-slice-release-run-commands.md | 78 +++++++++---------- .../rendering/docker_compose_templates.rs | 28 +++++++ src/domain/environment/context.rs | 10 ++- src/domain/environment/mod.rs | 9 +++ src/domain/environment/testing.rs | 10 +-- .../docker_compose/context/builder.rs | 15 ++++ .../wrappers/docker_compose/context/mod.rs | 10 +++ .../template/wrappers/env/context.rs | 46 +++++++++++ templates/docker-compose/.env.tera | 11 +++ .../docker-compose/docker-compose.yml.tera | 31 +++++++- 10 files changed, 201 insertions(+), 47 deletions(-) diff --git a/docs/issues/246-grafana-slice-release-run-commands.md b/docs/issues/246-grafana-slice-release-run-commands.md index 2fedac6c..f2d0be12 100644 --- a/docs/issues/246-grafana-slice-release-run-commands.md +++ b/docs/issues/246-grafana-slice-release-run-commands.md @@ -507,37 +507,37 @@ fn create_environment_from_config(config: UserInputs) -> Result` field to `UserInputs` struct -

charset=UTF-8 Content-Transfer-Encoding: 8bit This commit implements firewall configuration for Grafana UI access (port 3100), completing Phase 3 of the Grafana slice implementation. The firewall configuration follows the same pattern as tracker firewall with conditional execution based on Grafana configuration presence. ## Key Changes ### 1. Firewall Playbook (NEW) - Created `templates/ansible/configure-grafana-firewall.yml` - Opens port 3100 for Grafana UI (container port 3000 β†’ host port 3100) - Unconditional execution when playbook runs (decision at step level) - Reloads UFW firewall after rule changes ### 2. Ansible Variables Context (UPDATED) - Added grafana_config parameter to `AnsibleVariablesContext::new()` - Marked as unused (`_grafana_config`) - for future use if needed - No grafana_enabled variable needed (conditional at step level) - Updated all call sites and tests (1555 tests passing) ### 3. Template Rendering (UPDATED) - Extended `RenderAnsibleTemplatesStep` with grafana_config field - Updated constructor and execute() to pass grafana_config to renderer - Updated `AnsibleProjectGenerator::render()` with grafana_config param - Updated `AnsibleTemplateService` to pass grafana from user_inputs ### 4. Ansible Project Generator (UPDATED) - Registered `configure-grafana-firewall.yml` in `copy_static_templates()` - Updated file count comment: 17 files (ansible.cfg + 16 playbooks) - Playbook placed after `configure-tracker-firewall.yml` in list ### 5. Configure Command (UPDATED) - Added `ConfigureGrafanaFirewall` variant to `ConfigureStep` enum - Created `ConfigureGrafanaFirewallStep` following tracker firewall pattern - Integrated in `ConfigureCommandHandler` after tracker firewall step - Conditional execution: - Skip if `TORRUST_TD_SKIP_FIREWALL_IN_CONTAINER=true` - Skip if Grafana not configured (check `context().user_inputs.grafana`) - Execute only when Grafana is enabled in environment ## Design Decisions ### Pattern Choice: Step-Level Conditional Execution Unlike tracker firewall (which uses variable-based conditionals for port arrays), Grafana firewall uses **step-level conditional execution** because: 1. Grafana UI port is fixed (3100), not variable like tracker ports 2. Simpler to check presence of Grafana config at step level 3. Follows same pattern as Prometheus (no public firewall exposure) 4. Playbook always opens port 3100 when executed - simple & clear ### Why No `grafana_enabled` Variable? Initial implementation added `grafana_enabled` to variables.yml.tera, but this was removed because: 1. Tracker uses `when: tracker_udp_ports is defined` for conditionals 2. Grafana doesn't need variable-based conditionals (port is fixed) 3. Decision happens at step level: don't execute playbook if Grafana disabled 4. Simpler pattern: playbook unconditionally opens port when run ## Security Note This public port exposure is **temporary** until HTTPS support with reverse proxy is implemented.
