Common Docker errors and how to fix them
A quick reference to the Docker and Docker Compose errors you meet most often on a VPS, what each one means and the command that fixes it.
Deploy a Self-Hosted App with Docker Compose from Scratch
Write a compose.yaml, keep your secrets in.env, start the stack with docker compose up -d, then verify it and update it later without losing data.
Docker Compose depends_on and healthchecks: get startup order right
Use depends_on with condition: service_healthy so your app waits until the database accepts connections, and learn how to tune healthcheck timing without slowing every start.
Install Docker and Docker Compose on a Linux VPS
Install Docker Engine and the Compose plugin from Docker's own repository, run a first Compose project, cap log size and avoid exposing ports by accident.
Install Portainer to manage Docker containers from a web UI
Run Portainer CE on your Docker VPS, secure it with HTTPS and use it to start, stop, update and inspect containers, stacks, volumes and networks.
Monitor Docker containers with Prometheus, cAdvisor and Grafana
Run cAdvisor, Prometheus and Grafana in Docker Compose on a Linux VPS and get per-container CPU, memory, network and disk graphs in one dashboard.
Run a Node.js app with Docker Compose behind Nginx
Containerise a Node.js app with a small Dockerfile, run it with Docker Compose next to an Nginx reverse proxy, and add logs, restarts and HTTPS.
Self-host Nextcloud with Docker Compose, MariaDB and Redis
Run Nextcloud, MariaDB and Redis as containers on one Linux VPS. Build the compose file, set trusted domains and verify the stack end to end.
Update self-hosted containers safely with Watchtower
Watchtower pulls new images and restarts your containers on a schedule. This guide covers monitor-only runs, allowlists, notifications and settings that keep updates reversible.
Zero-downtime deploys with Docker Compose and a reverse proxy
Run blue-green container swaps behind Nginx so every deploy keeps serving traffic. Health checks gate the switch, and a reload moves traffic without dropping connections.
