Docker seems to be the big thing in the tech world right now. I started using it for some projects at work recently (not exactly how you're supposed to use Docker, but its working!) and I have loved it. Not only can I rebuild apps if they go down in an instant, but I am also savings tens of thousands of dollars PER MONTH! If you don't know what Docker is, is like a VM... But it isn't. Docker is all about putting apps in containers. You can have multiple containers per vm, all running apps with different dependencies. For example, say you have web apps. App one uses Apache tomcat , ruby 2x, java 7, and some other specific software versions. Web app two uses NGINX, java 8, ruby 1.9, and a in memory database. Normally, you would spin up two VMs, right? Well, not anymore. With Docker you can build these apps in a container, and have BOTH run at the same time on a single VM. The dependencies are in the container, and you don't have 'dependency hell'. So, thoughts on Docker? Anyone using it? BTW, if you are using Docker, I suggest looking at Packer to make you Docker Image. I use it, and I like it a LOT better than a Dockerfile. |

Interesting timing for this post. I was actually made aware of Docker when looking for something else that's kinda related... Though not sure what to think of the cost of the service itself given it's packaging mostly open source things. |

Also if you have any questions about Docker, feel free to ask. |

So you are looking at their paid service, but you dont HAVE to use it. Docker is open source and 'free'. It is licensed as open source with Apache. So software like this, that is open source and 'free', make money by offering a support service. https://www.docker.com/subscription-services However, you are able to download Docker and use it "About the Docker Project Our open source projects serve as a basis for our free and open Docker platform. In the last two years, over 450 million people worldwide have downloaded Docker’s open source software. This vibrant and ever-growing community of users and contributors represent the spirit the gave birth to, and fuels, Docker the company."-> https://www.docker.com/open-source tl:dr, you are legally allowed to use Docker as you wish for free. If you feel like hosting Docker on your own is too much, or you think you need advanced support and security, you can pay for the service. tl:dr2 - https://docs.docker.com/engine/faq/ Chef offers something similar, and even Jenkins offers a 'paid' service - https://wiki.jenkins-ci.org/display/JENKINS/Commercial+Support Download here for Mac btw -> https://docs.docker.com/engine/installation/mac/ |
