The Complete Docker Developer Course

Provision a production server, install docker, create a deploy user, build and push a monolithic node app to docker hub, and redeploy with a simple deploy script.

Learn a local development workflow with docker, sharing project files as volumes, managing dependencies inside the container, and live watching with nodemon and gnomon, plus docker compose and port mapping.

Learn to integrate a local database into your docker-based development workflow, using docker compose to spin up web and MySQL services, and manage migrations and fixtures for a production-consistent schema.

Create and connect a production database, run migrations against it, and redeploy the web server on a dedicated docker network to enable container communication.

Learn to back up and restore production data in Docker containers using mysqldump, volume backups, and tarball restores, with automated backups to aws s3.

Learn to implement continuous testing with CircleCI by containerizing tests in Docker, running npm test inside the build, and validating PRs with green or failing builds.

Learn how to implement continuous deployment from the master branch to production using CircleCI, Docker Hub, and SSH, with a secure deployment script and environment variables.

Extend a docker-based deployment workflow by adding staging and qa environments, implement environment-specific dockerfiles and deploy scripts, and integrate CircleCI to auto deploy on branch changes.

Explore why docker supports microservices over monoliths, highlighting scalable deployments, fault isolation, and incremental testing, and learn how to implement service patterns for stable, maintainable apps.

Discover why Docker is the ideal fit for microservices, delivering fast container builds, instant starts, scalable deployment, simple Dockerfiles, and flexible local multi-service development with Docker Compose.

Learn how to design fast, decoupled microservices with quick builds, rapid start times, and lightweight images, while owning data for independent deployment and seamless continuous delivery.

Identify discrete data sets and decouple data to break a monolith into microservices, using synchronous and asynchronous communication, data duplication for stability, and starting with one service at a time.

Learn how service discovery enables disposable Docker infrastructure by registering containers in a registry, auto reconfiguring load balancers, and using overlay networks for direct container communication and seamless failover.

Explore service registration and discovery with etcd, a simple key-value store, including registering services, TTL-based expiration, and watching configurations via LCD control.

Explore consul's service registration and discovery through a practical, container-based demo. Register web services across multiple nodes, view the catalog, and manage keys and deregistration via the API.

Learn to deploy a multi-node docker swarm across six nodes, with two managers, two load balancers, two app nodes, a console registry, and overlay networking for high availability.

Create a swarm with managers for failover and public load balancers for internal app containers, then deploy across two nodes using an overlay network to enable hostname-based communication.

Add tags and constraints to Docker swarm nodes to target containers to specific app nodes, using labels like environment production or staging to guide scheduling by the swarm manager.

Strengthen docker security by enabling passwordless root access via SSH keys, restricting management ports 4000, 80, 500, and 2375 with iptables, and using private networks to protect the swarm.

Learn practical service discovery patterns with automatic registration and dynamic load balancing, from dns failover to registry-based approaches using sidekicks.

Set up a lightweight registry on an apps network to let apps register and load balancers query, capturing ports, upstreams, hostnames, and ssl settings via environment variables.

Register services from within a running app using the cd registry with a ttl of 10 seconds. Renew every 5 seconds to keep upstreams like web1 and web2 alive.

Explore sidekick service registration, a separate container that performs health checks and robust http requests to registered services, with optional affinity and diagnostics. Evaluate its extra maintenance against traditional self-registration.

Learn how an automatic registry container registers and deregisters Docker services across swarm nodes, using environment variables to declare service name, virtual host, and port.

Learn dynamic load balancing with an nginx-based load balancer, service registration and discovery, and easy scaling of API and web containers with DNS failover.

Walk through the docker-based setup for a simple nginx stack, including a dockerfile, a bash script, cloudwatch logging, and a reloadable config with upstreams and ssl.

Demonstrates configuring ssl termination with a dockerized engine X container, converting a self-signed certificate to a one-line env var, and weighing runtime versus dockerfile deployment for easy ssl offloading.

Pin specific docker image versions, avoid latest tags, respect semantic versioning, run one process per container, and enable independent deployments with automated, secure networking.

Execute rolling deployments with Docker Swarm to deploy multiple containers for a hello world app, achieving zero downtime through continuous deployment, build, push, and scalable container updates.

deploy a new version alongside the current one, share traffic, monitor metrics, and perform fast rollbacks to ensure stability in red-black deployments.

Master blue-green deployments by switching traffic between blue and green versions via the service registry and load balancer, enabling near instantaneous rollbacks.

Implement versioning with multiple running containers to host V-1 and V-2 behind nginx, routing /v-1 and /v-2 to respective containers, enabling isolated upgrades without downtime.

Master Docker to scale containerized architecture and build a real production application. Gain confidence applying Docker in real projects, and engage with the community forums for ongoing support.
