About
Docker is the platform that popularized containerization — packaging applications and all their dependencies into lightweight, portable containers that run identically on any machine. dotCMS provides official Docker images and Docker Compose configurations, making it straightforward to spin up local development instances, run CI/CD pipelines, or deploy production environments. Containers eliminate the "it works on my machine" problem by ensuring that dotCMS, its Java runtime, Elasticsearch/OpenSearch, and supporting services all behave the same way regardless of the underlying infrastructure.
For development teams, Docker means faster onboarding, reproducible builds, and a clean path from local testing to cloud deployment — whether running on AWS, Azure, GCP, or self-hosted infrastructure.
