With the rise in popularity of microservices, Docker has gained popularity and has become the standard for containerization. Its ease of use in software delivery using containers has put it ahead of other containerization technologies such as rkt and LXD. I’ve lost count of the times I’ve come across popular official Docker images that were bloated and riddled with bugs and known vulnerabilities. This causes many developers to shun them in favor of building their own alternate images, causing duplication of effort, developer time and storage space and costs.
