Docker: the standard of modern containerisation
Docker has become widely adopted of application containerisation and an essential foundation of the modern DevOps ecosystem. By packaging code, dependencies and configuration into portable images, Docker guarantees reproducibility of environments (from developer workstation to production cluster), accelerates delivery cycles and simplifies multi-cloud deployment. Docker containers are now present in almost all modern CI/CD chains (GitLab, GitHub Actions, Jenkins) and orchestration platforms (Kubernetes, Amazon ECS, Azure Container Apps, Google Cloud Run).
In French-speaking Switzerland, Geneva private banks, international organisations around Lake Geneva, scale-ups, IT service companies, telecom operators, cantonal administrations and pharmaceutical industries adopt Docker to containerise their applications and deploy on Kubernetes or managed cloud services. ITTA offers the Docker catalogue, with Docker strongly represented in our Open Source parent. Our Docker training is delivered by DevOps engineers active on Docker and Kubernetes platforms for Swiss and international clients.
Following a recognised Docker training opens access to highly valued roles: full-stack developer mastering their environment, DevOps engineer, platform engineer, cloud engineer, Site Reliability Engineer, cloud architect, Kubernetes administrator. The Docker Certified Associate (DCA) certification remains a reference for Docker skill validation, particularly valued for platform and administrator profiles.
Whether you are a developer seeking to master your local environment, a DevOps engineer ramping up, a Kubernetes administrator, a cloud engineer or a containerised application architect, our Docker training in Geneva and Lausanne covers the skills expected to build robust Docker images, orchestrate containers and prepare the Docker Associate certification.
ITTA Docker catalogue: containerisation and administration
Docker Fundamentals
The path starts with Docker Fundamentals, covering essential concepts: Docker architecture (daemon, client, registry), Docker images, containers, Dockerfile and build good practices, volume management, Docker networking, Docker Compose to orchestrate multiple containers in development. This training is the ideal entry for any developer and engineer seeking to start with Docker, from image build to local multi-container execution.
Docker Administration
The Docker Administration module deepens advanced Docker usage: private registry management (Docker Registry, Harbor), container security (image scanning, secrets, isolation, Linux capabilities), image optimisation (multi-stage builds, distroless, BuildKit), Docker Swarm for basic orchestration, container monitoring and logging (Prometheus, Grafana, ELK), deployment patterns and advanced troubleshooting. It is the target for DevOps engineers and platform administrators industrialising Docker usage.
Docker Associate (DCA) Certification
The Docker Associate (DCA) Certification Preparation path prepares for the official Docker Certified Associate exam. The programme covers all evaluated skills: orchestration (Docker Swarm), Kubernetes basics, images and registries, Docker installation and configuration, networking, security, storage and volume management. DCA remains a reference certification on the market, particularly recognised for platform profiles.
Docker for developers and good practices
Beyond the main modules, our Docker training integrates good practices of containerised development: Dockerfile organisation, image size minimisation, secrets and environment variables management, hot reload in development, testing in containers, debugging in remote environments. These cross-cutting skills are now expected on all full-stack developer and DevOps engineer positions.
Docker and the publisher ecosystem at ITTA
Docker fits into a broader containerisation ecosystem. The containerisation orchestration sub-domain regroups all our Docker, Kubernetes and cloud-native platform training. The Kubernetes publisher is the natural complement to Docker for orchestration at scale. The CI/CD versioning delivery sub-domain deepens GitLab CI/CD and GitHub Actions, deeply linked to Docker through image build pipelines. Automation and Infrastructure as Code covers Ansible and Terraform, often used in complement to provision Docker platforms. Observability and security delivery covers Prometheus, Grafana and container security.
Docker trends in 2026
Docker continues to evolve in 2026. Docker Desktop remains a widely used tool tool for local containerised development, with enriched features (Dev Environments, Docker Scout for security, Docker Build Cloud for accelerated remote builds). BuildKit imposes itself as the modern build engine. Distroless images gain ground to reduce attack surface. OCI (Open Container Initiative) standards consolidate the ecosystem beyond Docker. Kubernetes remains the dominant orchestrator for production loads, with Docker Swarm keeping niche use cases. Container security (continuous scanning, image signing, supply chain security) becomes a central issue. Our pedagogical content regularly integrates these evolutions to remain aligned with current practices.
Docker training in Geneva, Lausanne and online
All our Docker courses are available on-site in our Geneva and Lausanne centres, as well as in interactive virtual classroom with a DevOps engineer live. Our sessions are organised in 5-week cycles. Each session includes hands-on labs on Docker Desktop and dedicated Linux environments, end-to-end image builds, multi-container compositions with Docker Compose and concrete cases inspired by real DevOps projects. Customised corporate training is also possible at your premises, in Geneva, Lausanne, Vaud and across French-speaking Switzerland, with a programme adapted to your technical stack (Docker, Kubernetes, OpenShift, cloud services) and priority industrialisation cases.
Why train on Docker at ITTA
ITTA offers the Docker catalogue, with Docker strongly represented in our Open Source parent. Our Docker trainers are DevOps engineers and cloud architects active on Docker and Kubernetes platforms for Swiss and international clients, covering application development, cloud infrastructure, industrialisation and container security. The Docker catalogue regroups our courses covering Docker Fundamentals, Docker Administration and preparation for the Docker Associate (DCA) certification. Our pedagogical team supports you in choosing the right path, preparing the DCA exam and identifying funding solutions adapted to your professional situation.
Our pedagogical approach favours learning by doing, with containers to build from the first hours, Dockerfiles to write, multi-service compositions to orchestrate and concrete cases inspired by real DevOps projects (multi-stage image build, Kubernetes deployment, GitLab CI/CD integration, security scanning). Each session combines training time, applied exercises and exchanges with the trainer, allowing each participant to progress at their own pace and to leave with skills directly usable in their professional context.
Our training is aimed at varied audiences: developers seeking to master their local environment, DevOps engineers ramping up, system administrators evolving, platform engineers, cloud architects, Site Reliability Engineers, platform teams. Our pedagogical team adapts the content to the participants’ context.

FAQ
Which Docker course to choose to start?
Docker Fundamentals is the natural entry for any developer, DevOps engineer or administrator discovering Docker. The module covers the essentials to build and run containers autonomously. For profiles already comfortable with Docker in development and seeking to industrialise it, Docker Administration is the next target. Our pedagogical team guides you according to your profile.
Docker or Kubernetes: where to start?
Docker is the natural foundation to master before Kubernetes: Kubernetes orchestrates Docker containers. We therefore recommend Docker Fundamentals then Docker Administration, then only Kubernetes Fundamentals. Profiles jumping directly to Kubernetes without mastering Docker often face difficulties on image and Dockerfile concepts. Our pedagogical team guides you.
Is the DCA certification still relevant in 2026?
Yes, the Docker Certified Associate (DCA) remains a reference certification on the market, particularly valued for platform and administrator profiles. It validates technical skills on orchestration, images, networking, security and Docker storage. Our Docker Associate training specifically prepares for the exam. Our pedagogical team supports you on the modalities.
Are your Docker courses available for companies?
Yes, the entire Docker catalogue is available in-house, in Geneva, Lausanne and in virtual classroom, with a programme adapted to your technical stack, orchestration platform (Kubernetes, Docker Swarm, managed cloud services) and priority industrialisation cases. Our team builds the specifications with you and organises sessions according to your calendar.
