This example demonstrates the automated, scalable deployment of multiple Immers virtual spaces on DigitalOcean, orchestrated through shell scripts and cloud-init configuration. The visualization maps the creation of three named droplets (`immers1`, `immers2`, `immers3`) on Ubuntu, each pre-configured via cloud-init to run the Immers app in Docker with customized environment variables. The script shows how to dynamically create DNS A records for each server's subdomain, notify the host via a small Node.js/Express server when each instance is ready, and includes a simulation mode for dry runs. The description highlights the interplay between cloud provisioning, DNS setup, and the notification webhook, making the scaling process transparent and auditable.

This visualization shows the deployment steps of a cloud-init configuration for setting up a Hetzner server with Docker services. It maps the sequence of shell commands, package installations, and Docker Compose operations that migrate existing web applications (Peertube, Jitsi, Dockprom) from a remote source. The code demonstrates Docker CLI usage, docker-compose for service orchestration, and SSH key management for automated transfers. The visualization likely uses a flowchart or timeline representation to display the command order, with plain text annotations highlighting long-running steps and networking setup like custom bridge networks.

This example shows a shell script that automates the deployment of a Dockerized application on a fresh Ubuntu server. The script installs Docker and Docker Compose, creates a project directory, and copies a `docker-compose.yml` file into it. It then sets up a systemd service to run the compose file on boot and starts the application. The code uses `curl` to fetch remote files, `usermod` for user permissions, and `systemctl` to enable the service, with the actual container orchestration handled by `docker-compose` and `docker` commands.

docker-swarm

This example demonstrates a Docker Swarm deployment of a PHP application behind an Nginx load balancer, using a Compose file to define the service topology. The visualization shows the network layer with an overlay network bridging the webapp replicas and the manager-node proxy, while the Nginx configuration references an upstream cluster with multiple server IPs. The PHP container serves a simple script that echoes the container’s hostname and IP, illustrating dynamic scaling behavior. The code relies on Docker Compose’s `deploy` keys for replica counts, update parallelism, and placement constraints.

traefik docker swarm

This example illustrates a live topology of a Docker Swarm cluster, mapping the deployment of a replicated web service and its routing through a Traefik load balancer. The visualization is generated with `dockersamples/visualizer`, reading the Docker engine’s socket (`/var/run/docker.sock`) to render nodes and connections. It shows three replicas of the `emilevauge/whoami` service behind Traefik, which is configured via Docker labels to handle the `hello.docker.localhost` host rule. The code also exposes a separate visualizer port (8081) and manager-node placement constraints.

Gist 3d7ff1d83fb2177cedceded587ff4aca

This example presents a setup guide for a Docker-based Node.js workshop, illustrating how to launch a project from a Bitbucket-hosted configuration. It shows the command sequence, starting with copying a `docker-compose.yml` file from the provided URL and then running `docker compose up --build` to construct and start the container image. The visualization focuses on the workflow steps, highlighting the use of Docker Compose for service orchestration and image building. The interface displays the copied configuration link alongside the terminal command, making the process explicit for users. No additional data or rendering occurs beyond these instructional elements.

A Packer template for building a Docker container host on an AWS EC2 instance.

This example shows a Packer template that automates the creation of an Amazon EC2 instance preconfigured as a Docker container host. The code defines an Amazon EBS builder using the `amazon-ebs` type, specifying an Ubuntu AMI and an `m3.xlarge` instance type. Provisioners run shell commands to install Docker Engine, add the `ubuntu` user to the `docker` group, and configure DNS via `DOCKER_OPTS`. The template also includes a `shell-local` provisioner to wait for a reboot, and uses variables for AWS credentials. The rendering approach is code-as-infrastructure, with no visual data involved.

Omeka-S on Debian w/Docker Compose

This example shows a complete setup for running Omeka-S, a digital-archive platform, on Debian using Docker Compose. The code first installs Docker and Docker Compose, then clones the `omeka-s-docker` repository and launches the containerized application with `sudo docker-compose up -d`. It relies on the Docker command-line interface and the Docker Compose tool, specifically using `docker-compose` to orchestrate the service. The gist does not include a data visualization; instead, it documents a server-deployment workflow, with the visible render being the terminal output from the install script and container startup. No charting or data-rendering libraries appear in this code.

Work-at-home Challenge for Blue Bottle Coffee DevOps Engineer

This example visualizes the DevOps challenge workflow for a Blue Bottle Coffee engineering role, showing the sequential stages of S3 bucket manipulation, directory-tree microservice generation, monitoring, containerization, and deployment. The code uses the AWS SDK for JavaScript to interact with S3 buckets and Redis for key-value storage, while the visualization maps the tree command output and JSON file handling steps. It highlights the integration of SNS/SQS for upload monitoring and Terraform for infrastructure provisioning, with Docker and ECS for virtualized state persistence. The rendering approach relies on d3.js to illustrate the branching logic and data flow across the pipeline.
