Docker 1.12: Now with Built-in Orchestration!
Three years ago, Docker made an esoteric Linux kernel technology called containerization simple and accessible to everyone. Today, we are doing the same for container orchestration.
Container orchestration is what is needed to transition from deploying containers individually on a single host, to deploying complex multi-container apps on many machines. It requires a distributed platform, independent from infrastructure, that stays online through the entire lifetime of your application, surviving hardware failure and software updates. Orchestration is at the same stage today as containerization was 3 years ago. There are two options: either you need an army of technology experts to cobble together a complex ad hoc system, or you have to rely on a company with a lot of experts to take care of everything for you as long as you buy all hardware, services, support, software from them. There is a word for that, it’s called lock-in.
Docker users have been sharing with us that neither option is acceptable. Instead, you need a platform that makes orchestration usable by everyone, without locking you in. Container orchestration would be easier to implement, more portable, secure, resilient, and faster if it was built into the platform.
Starting with Docker 1.12, Continue reading
