The Linux Foundation has recently published a whitepaper by Armijn Hemel that seeks to uncover the complexities of open source licensing implications when distributing and deploying Docker containers - it can be downloaded here. This blog post is a summary of the general findings. Docker containers hide many of the implementation details, and developers might end up unknowingly shipping all kinds of software without knowing the license compliance issues that occur as a result. For example, using containers makes it easier for developers to deploy software, but it also makes it easier to deploy (sometimes inadvertently) the wrong thing. Containers allow services to be isolated from each other and require far fewer resources from a virtual machine, so they are becoming extremely popular in extremely dense multi-tenant hosting environments run by hyper-scale cloud providers, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud.ĭocker has had a significant impact on the popularity of containers and has made it much simpler on the technological side of things, but on the legal side, there are potentially increased complexities.
A few years ago, a person had to install a Linux based OS distribution with the necessary software and dependencies - these days, it is now much more common to “spin up a Docker container” and run a service.Ī container is basically nothing more than one or more applications with all dependencies, data, and configuration in a single isolated environment that can be deployed without the need to buy a new system or create a virtual machine.
Deployment, distribution, and execution of software and especially services have significantly changed in the last few years.
