Containerization technologies are one of the trendiest topics in the cloud economy and the IT ecosystem. The container ecosystem can be confusing at times, this post may help you understand some confusing concepts about Docker and containers. We are also going to see how the containerization ecosystem evolved and the state of containerization in 2019. Put on your swimming suit, because this is a deep dive. 🏊‍♀️🏊

Today containerd graduated within the CNCF to join the ranks of Kubernetes, Prometheus, Envoy, and CoreDNS as a “graduated” project in the CNCF. From Michael Crosby on the Docker blog: We are happy to announce that as of today, containerd, an industry-standard runtime for building container solutions, graduates within the CNCF. From Docker’s initial announcement that it was spinning out its core runtime to its donation to the CNCF in March 2017, the containerd project has experienced significant growth and progress over the last two years. The primary goal of Docker’s donation was to foster further innovation in the container ecosystem by providing a core container runtime that could be leveraged by container system vendors and orchestration projects such as Kubernetes, Swarm, etc.

The adoption of application container technology is increasing at a remarkable rate and is expected to grow by a further 40% in 2020, according to 451 Research. It is common for system libraries to be available in many docker images, as these rely on a parent image that is commonly using a Linux distribution as a base. In many cases, remediation is as simple as rebuilding the image or swapping out the base image, but it’s not always that easy. Click through for more analysis and advice.

Testing code that talks to the database can be slow. Fakes are fast but unrealistic. What to do? With a little help from Docker, you can write tests that run fast, use the real database, are easy to write and run. I tried Itamar’s technique on changelog.com’s test suite and the 679 tests complete in ~17 seconds. The same tests run directly against Postgres complete in ~12 seconds. A net loss for me, but that may have something to do with how Docker for Mac works? I’d love to hear other people’s experiences.

750 downvotes and counting on the comment below from Joao Fernandes, the Docs Lead for Docker Enterprise Edition. I know that this can feel like a nuisance, but we’ve made this change to make sure we can improve the Docker for Mac and Windows experience for users moving forward. As far as I can tell, the docs don’t need changes, so I’ll close this issue, but feel free to comment. Lots of comments are stacking up on Hacker News too.

Is Netflix Titus open source yet? Yes. Titus powers critical aspects of the Netflix business, from video streaming, recommendations and machine learning, big data, content encoding, studio technology, internal engineering tools, and other Netflix workloads So, why is Netflix open sourcing Titus? …we’ve been asked over and over again, “When will you open source Titus?” It was clear that we were discussing ideas, problems, and solutions that resonated with those at a variety of companies, both large and small. We hope that by sharing Titus we are able to help accelerate like-minded teams, and to bring the lessons we’ve learned forward in the container management community. The question is, is it too late for Titus to gain traction in a world where Kubernetes has seemingly already won?

I found this section of the announcement insightful: Most ideas never materialize. Most software goes unused. Most businesses fail in their first year. Yet here we are, one of the largest open-source communities ever assembled, collectively building software that will run on millions of computers around the world. To know that your work was meaningful, and that a vibrant community of people will continue building upon it…. can any founder ask for anything more? Best of luck to you, Solomon. We’ll be waiting to see what you hack together next!
