DevOps

DevOps notes — containers, cloud, observability, and how code becomes running systems. This map will grow as I add notes on the tools and patterns I actually use.

CI and Git

• GitLab — most of my day-to-day CI lives here. See the GitLab MOC.

Containers and orchestration

• Docker — images and local/prod containers.
• Kubernetes — cluster orchestration.

Observability

• LGTM stack — Loki, Grafana, Tempo, Mimir (Grafana’s bundled story).
• Grafana — dashboards and correlation UI.
• Prometheus — metrics and PromQL.
• Loki — log aggregation.
• Grafana Tempo — distributed tracing backend.
• Elasticsearch and Kibana — search, logs, and Elastic Stack UI.

Cloud providers

• AWS, Google Cloud Platform (GCP), Microsoft Azure.

Infrastructure as code

• Infrastructure as Code (IaC) — versioned, automated infra.
• Terraform — HCL-first declarative provisioning.
• Pulumi — IaC in TypeScript and other languages.
