Docker was introduced in 2013 and quickly became an important technology in modern software development and infrastructure management. Its container-based architecture builds on earlier operating-system virtualization concepts while providing a practical way to run isolated workloads without the overhead of traditional virtual machines. The Docker Engine, container images, registries, networks, and volumes form the core components of the Docker ecosystem, allowing developers and system administrators to build, distribute, deploy, and maintain applications efficiently.

Today, Docker is used across a broad range of workloads, including web applications, APIs, databases, development environments, automation platforms, and self-hosted services. Containers can be created, stopped, updated, connected through virtual networks, and managed independently, making Docker particularly useful for environments where applications need predictable deployment and flexible resource management. When deployed on a VPS, Docker can provide a practical foundation for running multiple isolated services on the same server while retaining control over the underlying operating system and infrastructure.

For users looking to run Docker on GhostVPS infrastructure, the available options vary by VPS provider and operating system. The Application selection is available with selected plans across supported providers, allowing users to first choose the VPS infrastructure and resources that fit their workload and then select Docker together with an available operating system during server deployment.
