Docker description
Docker is a tool that lets you package and run software in standardized units called "containers." Imagine a container ship, but for software! This makes it easy to move and deploy applications reliably across different environments, like your own servers or the cloud. Docker is especially popular with developers and IT teams at companies of all sizes because it simplifies software management and makes deployments smoother.
Who is using Docker?
Who is Docker best for
Docker simplifies how developers and IT teams manage applications. We find that its containerization technology is especially useful for ensuring environment consistency and effective dependency management. Users appreciate its wide range of features and integration with cloud environments, noting the extensive documentation and strong community support. We have observed that new users face a learning curve, and some report issues with memory consumption and networking, but overall Docker is a well-regarded solution.
-
Great for companies of any size, from startups to large enterprises, seeking streamlined software deployment.
-
Perfect for the Software, IT, and Telecommunications industries to simplify application management and deployment processes.

Docker reviews
We've summarised 758 Docker reviews (Docker GetApp reviews, Docker Capterra reviews and Docker G2 reviews) and summarised the main points below.
- Easy application deployment and environment consistency across platforms
- Effective dependency management and isolation of applications
- Wide variety of features and seamless integration with cloud environments
- Strong community support and extensive documentation
- Docker Hub provides a vast repository of pre-built images
- High memory consumption, especially the Docker daemon
- Occasional networking issues, particularly with Docker Swarm
- Lack of enterprise-level support for production environments
- Steep learning curve for beginners, especially with CLI
Docker pricing
The commentary is based on 43 reviews from Docker Capterra reviews and Docker G2 reviews.
We find that Docker's free tier is generally sufficient for personal use. However, some users feel the paid features, like unlimited image pulls and automated builds, are necessary for professional use and justify the cost. Others have expressed concerns about the pricing of private repositories and some previously free features.
