It works on everyone’s machine. Docker eliminates the “but it worked on my laptop” problem. “I love docker because it takes environment specific issues out of the equation – making the developer’s life easier and improving productivity by reducing time wasted debugging issues that ultimately don’t add value to the application. Takes the pain out of CI/CD. If there is one thing developers hate, it is doing the same thing over and over. “Docker completely changed my life as a developer! I can spin up my project dependencies like databases for my application in a second in a clean state on any machine on our team! I can‘t not imagine the whole ci/cd-approach without docker. Automate all the stuff? Dockerize it!” Boosts your career. According to a recent Indeed report, in the last year, job postings listing Docker as a preferred skill have increased almost 50%. And the share of job searches per million including Docker has increased 9,538% since 2014. Makes cool tech access...

If you haven't already started exploring Docker then you will have no doubt heard and read about it. Docker containers are challenging VMs as a new favourite tool for devops and developers alike. In this article, we will take a look at the basics and what a Docker image vs container is all about. You are probably already well familiar with the typical virtual machine setup. In essence, you select your server configuration, such as memory, CPU and so on and then an operating system to run upon it. Underlying the virtual machine, somewhere in the stack, is some physical hardware and the resources are shared between virtual machines. The host hardware performs a balancing act of sharing resources between all the virtual machines, giving more computing power when required and shifting it around accordingly. This is the defacto offering for most hosting providers - you "own" the virtual machine and are entirely responsible for its running. In the VM scenario, all inst...

I run into this scenario a lot as a freelance developer. Companies will request that any code you write for their project will 100% belong to them. They want to own all of the IP (intellectual property) for every line of code and they’ll ask you to sign contracts to agree. A vast majority of companies just take existing contracts they have for their full time employees, tweak a few sentences to make it apply to contract work and then call it a day. So it’s no surprise that you’ll eventually get to the section of the contract on code ownership and you’ll get hit with a wall of text that says you forfeit the right to use, reuse, copy, talk about, write about or distribute any line of code outside the context of this project. Full Time Employment and Contracts Are Different The limitations imposed by the above contract are pretty strict but if you’re a full time employee and that’s the only code base you’ll be working on for the next few years, then it’s not totally out of the ...

We’ve talked a lot about how Docker Enterprise supports and simplifies Kubernetes. But how are organizations actually running Kubernetes on Docker Enterprise? What have they learned from their experiences? Here are three of their stories: McKesson Corporation When you visit the doctor’s office or hospital, there’s a very good chance McKesson’s solutions and systems are helping make quality healthcare possible. The company ranks number 6 in the Fortune 100 with $208 billion in revenue, and provides information systems, medical equipment and supplies to healthcare providers. The technology team built the McKesson Kubernetes Platform (MKP) on Docker Enterprise to give its developers a consistent ecosystem to build, share and run software in a secure and resilient fashion. The multi-tenant, multi-cloud platform runs across Microsoft Azure, Google Cloud Platform and on-premise systems supporting several use cases: Monolithic applications. The team is containerizing an existing ...

We recently Dockerized the main part of our event processing pipeline using the 1.12-rc4 release. It’s been awesome using Docker in Swarm mode, and we’ve been really impressed with the ease of setup and use of Swarm mode. Our event pipeline processes around 220 million application errors per day, approximately 150k per minute, and performs a massive variety of processing tasks — it’s a critical piece of our infrastructure. The new version of Docker Engine introduces native clustering capabilities, built directly into the daemon (as opposed to running a separate set of processes). This, in our opinion, positions Docker as a serious competitor in the container orchestration space (alongside giants like Kubernetes and Mesos), and will make building and operating large distributed applications easier for everyone. Docker Swarm mode A quick look at Bugsnag’s error processing architecture As you probably know, Bugsnag is an error monitoring platform. As part of this, we have to ac...
