What we're about

The Manchester Java Community is a group for Java professionals interested in gathering and sharing knowledge in the industry.

It's open to beginners to experts, developers to managers, geek to professionals.

Membership is restricted to Java developers (or those hoping to train in Java).

Membership will not be granted to those involved in the recruitment industry.

Meetings are to be held monthly in the Manchester, UK, area and are free to attend.

A Hitchhiker's Tour to Containerising a Java application - Nicolas Frankel

While a plain Dockerfile gets the job done, there are actually many more ways to containerize your Java app. They come with a couple of pros, and some cons. As “the Cloud” becomes more and more widespread, now is a good time to assess how you can containerize your Java application. I assume you’re able to write a a Dockerfile around the generated JAR. However, each time the application’s code will change, the whole image will need to be rebuilt. If you’re deploying to a local Kubernetes cluster environment, this increases that much the length of the feedback loop. In this demo-based talk, I’ll present different ways to get your Java app in a container: Dockerfile, Jib, and Cloud Native Buildpacks. We will also have a look at what kind of Docker image they generate, how they layer the images, whether those images are compatible with skaffold, etc. Speaker: Nicolas Frankel Developer Advocate with 15+ years experience consulting for many different customers, in a wide range of contexts (such as telecoms, banking, insurances, large retail and public sector). Usually working on Java/Java EE and Spring technologies, but with focused interests like Rich Internet Applications, Testing, CI/CD and DevOps. Currently working for Hazelcast. Also double as a trainer and triples as a book author. If you've any ideas or feedback for the group then you can either join us at the meetup or contact us via email ([masked]) or on Twitter (https://twitter.com/mcrjava).

DevOps for developers (or maybe against them?!) - Baruch Sadogursky

"DevOps" is the operations people’s crafty plan to make developers do other people's work, but we are smart enough to see right through this naive rebranding trick! Baruch suggests you think about it: we, the developers, have written all the code. It passes all the tests; it obviously works, and works well (Are we a little proud? We are!); so we are DONE. Now, out of the blue, a bunch of "thought leaders" (all with an operations background, mind you!) are trying to tell us that we have to learn YAML, Docker, Kubernetes and Terraform to deploy our software because suddenly it is our concern?! In this talk, we'll discuss why developers do or don’t need DevOps. We'll consider arguments made by DevOps visionaries and see whether they hold water. Hopefully, by the end of the talk, we'll understand whether DevOps really helps developers to deploy better code to production more often, or if it is just another scam made up by marketing and evangelists. This is a fun and provocative talk. I am starting with claiming that developers have no incentives to do any DevOps and will work my way to explain why although there is some truth in that, it doesn't' really matter. The business must commit to DevOps and once the business committed, everyone has to be on-board. Speaker: Baruch Sadogursky Baruch Sadogursky (a.k.a JBaruch) is the Head of DevOps Advocacy and a Developer Advocate at JFrog. His passion is speaking about technology. Well, speaking in general, but doing it about technology makes him look smart, and 19 years of hi-tech experience sure helps. When he’s not on stage (or on a plane to get there), he learns about technology, people and how they work, or more precisely, don’t work together. He is a co-author of the Liquid Software book, a CNCF ambassador and a passionate conference speaker on DevOps, DevSecOps, digital transformation, containers and cloud-native, artifact management and other topics, and is a regular at the industry’s most prestigious events including KubeCon, DockerCon, Devoxx, DevOps Days, OSCON, Qcon, JavaOne and many others. You can see some of his talks at jfrog.com/shownotes --- If you've any ideas or feedback for the group then you can either join us at the meetup or contact us via email ([masked]) or on Twitter (https://twitter.com/mcrjava).
