Docker signals the end for the Puppet and Chef

Docker signals the end for the Puppet and Chef

DockerCon sailed through Seattle recently, leaving behind in its wake a new swath of rapid adopters plus a trail of related company and product announcements. Docker itself produced perhaps the most exciting

Docker’s rapid adoption and deep penetration signal the beginning of the end for the Puppet and Chef IT automation platform.

As Containers Catch On, So Do Concerns

As Containers Catch On, So Do Concerns

Persistent storage requirements have overtaken security as the top barrier to adoption of application containers in production, according to a new adoption survey.

The container market adoption survey released Thursday (June 16) by data management software vendor ClusterHQ

“The biggest challenges to container deployment include persistent storage, networking, security and data management”

Nine out of 10 developers are likely or very likely to boost their use of containerized applications in the coming year, according to a new survey of 300 developers byShippable.

“Companies are realizing the productivity and flexibility gains they were expecting, and use of container technology is clearly on the rise,” said Shippable CEO Avi Cavale

Houses are VMs, apartments are containers

Houses are VMs, apartments are containers

Nice analagy from Mike Coleman about the underlying architecture of Docker.

Houses (the VMs) are fully self-contained and offer protection from unwanted guests. They also each possess their own infrastructure – plumbing, heating, electrical, etc. Furthermore, in the vast majority of cases houses are all going to have at a minimum a bedroom, living area, bathroom, and kitchen. I’ve yet to ever find a “studio house” – even if I buy the smallest house I may end up buying more than I need because that’s just how houses are built.  (for the pedantic out there, yes I’m ignoring the new trend in micro houses because they break my analogy)

Apartments (the containers) also offer protection from unwanted guests, but they are built around shared infrastructure. The apartment building (Docker Host) shares plumbing, heating, electrical, etc. Additionally apartments are offered in all kinds of different sizes – studio to multi-bedroom penthouse. You’re only renting exactly what you need. Finally, just like houses, apartments have front doors that lock to keep out unwanted guests.

Announcing Docker Cloud

Announcing Docker Cloud

Another new feature and revenue generator for Docker.  This announcement officially integrates the features from Tutum (an acquisition made in Oct of 2015).  Tutum is a cloud service used by developers and sysadmins to deploy and manage Docker applications.

Docker Cloud is where developers and IT ops meet to build, ship and run any application, anywhere. Over the past few months our team has been hard at work expanding on the features of Tutum and building native integration with Docker Hub, Docker ID (the new shared account system across all Docker services), Docker official repositories, and commercially supported Docker Engine (CS Engine).

Start using Docker Cloud today by logging in to Docker Cloud using your Docker ID.

Scaling with Docker Part 1

Scaling with Docker Part 1

Good introductory read on scaling with Docker from Brandon Okert 

Feb 16, 2016

This is the first in a two part post about Scaling with Docker. In Part 1, we’ll focus on getting started with Docker from a scaling perspective. For the most part this will be an intro to Docker, so if you’re already experienced using mutli-container hosts, docker networks, volume containers, monitoring tools, and management scripts, feel free to skim this part. In Part 2, we’ll use the fundamentals from Part 1 to organize scalable multi-host systems, then show where to start to take that to very large scale applications.

Docker: 70,000% increase in job postings

Amazing stats posted by 

 

More than a 70,000% increase in job postings around the world. It’s safe to say that companies all over are investing heavily in Docker to transform their application lifecycles. That means it’s a great opportunity for developers and ops pros who already have hands on experience building, shipping and running Dockerized distributed applications. Docker is also an essential tool for any DevOps team and their CI/CD pipeline and will be an incredible asset as you look for jobs in the fast moving DevOps job market as well.
