Ubuntu is a Debian-based Linux operating system based on free software.
Ubuntu announced their minimal images a little while ago. Since then the default latest tag on Docker Hub for Ubuntu has pulled a minimal image. This is only 31mb compressed and 81mb on disk. You get access to a full CVE database but this time you get 5 years patch support and the option of paying for commercial support.
This is definitely a good choice for free base image. Read our comparison blog to see how it compares to the others.
