Deploy a multi-container Docker Compose app on Ubuntu 24.04 with Node.js, PostgreSQL, Redis, secrets, health checks, private networking, backups, and persistence.
Install Docker on Ubuntu 24.04 from Docker’s official APT repository. Add Docker Engine, Compose and Buildx, verify hello-world, and avoid common UFW exposure mistakes.
Compare buildpacks and Dockerfiles for app deployment: control, portability, system packages, build reproducibility, health checks, secrets, and persistent state.
Run Docker on a cloud VM with a clear production model for security, networking, storage, monitoring, and recovery.
Compare serverless vs containers across architecture, scaling, cost, portability, runtime control, serverless containers, Kubernetes, and common use cases.
Learn how to scale beyond one Docker Compose host with role separation, multiple app VMs, load balancing, shared state, Swarm, and a clean path to orchestration.
Back up and restore a Docker Compose stack by protecting configuration, secrets, persistent data, databases, images, and a tested clean-host recovery path.
Design Docker Compose networking for production with deliberate port publishing, private services, service-name DNS, network segmentation, and safer host exposure.
Use this Docker host security checklist to harden production VMs across daemon access, privileges, networking, images, secrets, updates, and recovery.
Control Docker CPU, memory, logs, and disk growth on production VMs with clear limits, rotation, monitoring, and safe cleanup policies.
Choose Docker, Compose, K3s, or managed Kubernetes based on ownership, multi-host needs, scaling, and recovery.
Use Docker Compose in production with practical best practices for configuration, security, health checks, releases, storage, backups, monitoring, recovery, and single-host limits.
Compare Docker vs virtual machines across isolation, performance, security, portability, Docker on a VM, and when an app platform is simpler than managing a server.
Learn when block storage fits databases, Docker containers, and stateful app data, including independent scaling, persistence, backups, recovery, and when object storage or managed databases are a better fit.
Compare cloud block storage vs local disk by lifecycle, databases, containers, scaling, performance, backups, and when a separate persistent volume is worth using.
Compare KVM VPS vs OpenVZ containers across kernel control, Windows and Docker support, isolation, performance, resource guarantees, recovery, and workload fit.
Learn when Docker VPS hosting fits production apps, how to size a Docker host, manage Compose, volumes, networking, backups, security, and when to move to Kubernetes.
Compare container images vs VM images for deployment, security, updates, rollback, portability, and small-team infrastructure decisions.
Compare Podman vs Docker for small teams: rootless security, Docker compatibility, Compose vs Quadlet, migration risks, and when to switch runtimes.
Compare Docker volume vs bind mount for production: persistence, host paths, Compose behavior, permissions, down -v, backups, and when to use each.
Docker Compose vs Kubernetes for small teams: compare production fit, migration triggers, operational cost, readiness, and a staged Raff infrastructure path.
