Docker vs IBM Containers: What are the differences?
Developers describe Docker as "Enterprise Container Platform for High-Velocity Innovation". The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere. On the other hand, IBM Containers is detailed as "Fully managed Kubernetes Offering by IBM". Managed Kubernetes offering to deliver powerful tools, an intuitive user experience, and built-in security and isolation to enable rapid delivery of applications all while leveraging Services including Watson, Weather, IoT, etc.
Docker can be classified as a tool in the "Virtual Machine Platforms & Containers" category, while IBM Containers is grouped under "Containers as a Service".
Some of the features offered by Docker are:
- Integrated developer tools
- open, portable images
- shareable, reusable apps
On the other hand, IBM Containers provides the following key features:
- Managed Kubernetes with simplified cluster management from IBM
- Cluster isolation choice (virtual - shared or dedicated compute and bare metal)
- Vulnerability Advisor introspects every layer in each image for known vulnerabilities and configuration weaknesses, as well as live container scanning
Docker is an open source tool with 54K GitHub stars and 15.6K GitHub forks. Here's a link to Docker's open source repository on GitHub.
lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.
