• The platform provides a centralized patching and deployment system for users who opt into the service
• For users who do not use the commercial update service, Core OS provides a package manager (Docker) to manage updates
• Core OS has made its updates available for free as a community service, and commercial products are used to sustain the effort
• Docker was initially used as a package manager and was a key component in building the Core OS system
• The platform has also developed a tool called etcd, a distributed key-value store, to enable sharing of configuration across servers and to make it easier to build distributed platforms.
• etcd's GitHub page and its maturity as an open-source project
• Docker's evolution from a tool to a platform and its divergence from the original containerization philosophy
• The reasons behind the creation of Rocket, a new tool for containerization, and its specifications
• The announcement and reception of Rocket, including the subsequent press frenzy and controversy
• The team's internal reaction to the launch of Rocket and the handling of external pressure and criticism
• The lack of an open standard for containerization was a major issue
• CoreOS decided to build their own solution, Rocket, instead of contributing to Docker
• Rocket aims to provide a more secure, composable, and Unix-like containerization solution
• CoreOS has invested in Rocket and it's coming along nicely
• The goal is to create a shared standard for containerization between Rocket and Docker
• Containers will be more widely adopted when there's a clear, open standard in place
• Multiple implementations of a standard exist and it's beneficial for everyone
• CoreOS is guiding the direction of containerization, but also wants to create a better Docker
• The focus is on creating a better containerization solution, not just duplicating Docker
• Docker and Rocket are compared and contrasted
• The interviewee sees Rocket as a container runtime, like the original concept of Docker, while Docker is a more comprehensive platform
• The interviewee believes that Rocket and Docker serve different purposes and are not redundant efforts
• The interviewee discusses the benefits of competition in the marketplace, citing Firefox and Chrome as an example
• The interviewee highlights security concerns with Docker's architecture and the need to refactor it to separate individual applications
• The interviewee notes that rewriting Docker's architecture would be necessary to address these security concerns.
• Discussion of Docker's security issues and the decision to refactor it into individual components
• Comparison of Docker to Chrome and Firefox, and the idea of making it more composable and interoperable
• Rocket's creation from scratch instead of forking Docker, due to differences in architecture and goals
• Docker's change of business model from Docker Cloud to a new model, and its impact on the containerization ecosystem
• Core OS's business model and approach to monetization through free updates and community services
• App Container specification, a community-driven effort to standardize containerization
• Review of the App Container specification, its components, and ownership.
• Runtime environment consistency and portability
• Container state and arguments (environment variables, config drive, metadata service)
• Identity for containers (signed version of data posted to metadata service)
• Image format, runtime, and image discovery specification
• Docker's tightly integrated hub and image discovery/download process
• Open source and interoperability with Rocket and Go programming language
• App container specification progress and involvement opportunities
• Rocket and CoreOS product transition and support for Docker
• Motivation for Rocket and containers is to treat them like a package manager, with always-up-to-date packages
• Desire to deliver updates quickly to Docker platform users, not just package managers
• CoreOS can run anywhere, including Amazon, Digital Ocean, Google, and on-prem
• Root file system is bit-for-bit identical, ensuring security and portability
• Quay plays a role in the future of CoreOS and app container standards
• Enterprise-ready on-prem Docker registry is available from Docker
• Features of Quay will support app container and Docker standards
• CoreOS will power development and bug fixing across the spectrum
• Open source and core OS development
• Security and auto-updating of OS
• App container standard and interoperability
• Need for third-party implementations of app container spec
• Contribution opportunities for listeners, including system programming and distributed database work
• App container spec available on GitHub as appc
• Core OS CEO discusses what they would be doing if they weren't working at Core OS.
• Desire to work more directly on products and technology.
• Enjoyment of outdoor activities, such as windsurfing and white water rafting.
• Mention of inflatable kayaks for river crossings.
• Appreciation for being part of Core OS team and having control over projects.
• Acknowledgement of sponsors, including Rackspace and CodeShip.
[0.00 --> 15.86] welcome back everyone this is the change log and i'm your host adam stekowiak this is episode 138
[15.86 --> 23.14] jared and i talked to alex pulvey the ceo of core os great conversation today talking about
[23.14 --> 28.78] containerization specifically their awesome new open source product called rocket a competitor
[28.78 --> 34.56] to docker specifically to standardize the app container spec great conversation around that as
[34.56 --> 41.04] well um alex great guy today going to have this conversation we have some awesome sponsors making
[41.04 --> 46.12] the show possible code ship top towel and for those who do not know what i'm saying when i say top towel
[46.12 --> 54.24] i'm saying t-o-p-t-a-l.com i'm assuming their their name i have never asked brendan this so this is

[65.32 --> 70.36] have the support of rack space we'll tell you a bit about those guys later in the show but code ship
[70.36 --> 75.64] is an awesome sponsor of ours uh in fact one cool thing i want to mention about code ship recently
[75.64 --> 81.02] they just listened to all sorts of feedback they got from their users uh and recently redesigned
[81.02 --> 85.48] their entire application not only does the new design look better but it also has tons of new
[85.48 --> 90.24] usability improvements to make things even easier than before you can set up continuous integration
[90.24 --> 95.06] for your app in just a few steps and to pull your code with all your tests to pass no matter what
[95.06 --> 98.00] language you use no matter what framework you use they have great support for lots of languages
[98.00 --> 103.84] and frameworks they integrate with github or bitbucket uh you can deploy to cloud services like
[103.84 --> 110.40] roku and aws setup takes just three minutes you can find code ship at code ship.com
[110.40 --> 117.04] slash the changelog make sure you go to that url use the offer code the changelog podcast to get a
