Docker updates focus on simplifying containerization for developers

Over the last five years, Docker has become synonymous with software containers, but that doesn’t mean every developer understands the technical details of building, managing and deploying them. At DockerCon this week, the company’s customer conference taking place in San Francisco, it announced new tools that have been designed to make it easier for developers, who might not be Docker experts, to work with containers.

As the technology has matured, the company has seen the market broaden, but in order to take advantage of that, it needs to provide a set of tools that make it easier to work with. “We’ve found that customers typically have a small cadre of Docker experts, but there are hundreds, if not thousands, of developers who also want to use Docker. And we reasoned, how can we help them get productive very, very quickly, without them having to become Docker experts,” Scott Johnston, chief product officer at Docker told TechCrunch.

To that end, it announced a Beta of Docker Enterprise 3.0, which includes several key components. For starters, Docker Desktop Enterprise lets IT set up a Docker environment with the kind of security and deployment templates that make sense for each customer. The developers can then pick the templates that make sense for their implementations, while conforming with compliance and governance rules in the company.

“These templates already have IT-approved container images, and have IT-approved configuration settings. And what that means is that IT can provide these templates through these visual tools that allow developers to move fast and choose the ones they want without having go back for approval,” Johnston explained.

The idea is to let the developers concentrate on building applications, and the templates provide all the Docker tooling pre-built and ready to go, so they don’t have to worry about all of that.

Another piece of this is Docker Applications, which allows developers to build complex containerized applications as a single package and deploy them to any infrastructure they wish — on-prem or in the cloud. Five years ago when Docker really got started with containers, they were a simpler idea, often involving just a single one, but as developers broke down those larger applications into microservices, it created a new level of difficulty, especially for operations who had to deploy these increasingly large sets of application containers.

“Operations can now programmatically change the parameters for the containers, depending on the environments without having to go in and change the application. So you can imagine that ability lowers the friction of having to manage all these files in the first place,” he said.

The final piece of that is the orchestration layer and the popular way to handle that today is with Kubernetes. Docker has created its own flavor of Kubernetes, based on the open source tool. Johnston says, as with the other two pieces, the goal here is to take a powerful tool like Kubernetes and reduce the overall complexity associated with running it, while making it fully compatible with a Docker environment.

For that, Docker announced Docker Kubernetes Service (DKS), which has been designed with Docker users in mind including support for Docker Compose, a scripting tool that has been popular with Docker users. While you are free to use any flavor of Kubernetes you wish, Docker is offering DKE as a Docker-friendly version for developers.

All of these components have one thing in common besides being part of Docker Enterprise 3.0. They are trying to reduce the complexity associated with deploying and managing containers and to abstract away the most difficult parts, so that developers can concentrate on developing without having to worry about connecting to the technical underpinnings of building and deploying containers. At the same time, Docker is trying to make it easier for the operations team to manage it all. That is the goal, at least. In the end, DevOps teams will be the final judges on how well Docker has done, once these tools become generally available later this year.

The Docker Enterprise 3.0 Beta will be available later this quarter.

Docker has raised $92 million in new funding

Uber co-founder Garrett Camp steps back from board director role

Uber co-founder Garrett Camp is relinquishing his role as a board director and switching to board observer — where he says he’ll focus on product strategy for the ride hailing giant. Camp made the announcement in a short Medium post in which he writes of his decade at Uber: “I’ve learned a lot, and realized that I’m most helpful when focused on product strategy & design, and this is where I’d like to focus going forward.” “I will continue to work with Dara [Khosrowshahi, Uber CEO] and the product and technology leadership teams to brainstorm new ideas, iterate on plans and designs, and continue to innovate at scale,” he adds. “We have a strong and diverse team in place, and I’m confident everyone will navigate well during these turbulent times.” The Canadian billionaire entrepreneur signs off by saying he’s looking forward to helping Uber “brainstorm the next big idea”. Camp hasn’t been short of ideas over his career in tech. He’s the co-founder of the web 2.0 recommendatio...

Drone crash near kids leads Swiss Post and Matternet to suspend autonomous deliveries

A serious crash by a delivery drone in Switzerland have grounded the fleet and put a partnership on ice. Within a stone’s throw of a school, the incident raised grim possibilities for the possibilities of catastrophic failure of payload-bearing autonomous aerial vehicles. The drones were operated by Matternet as part of a partnership with the Swiss Post (i.e. the postal service), which was using the craft to dispatch lab samples from one medical center for priority cases. As far as potential applications of drone delivery, it’s a home run — but twice now the craft have crashed, first with a soft landing and the second time a very hard one. The first incident, in January, was the result of a GPS hardware error; the drone entered a planned failback state and deployed its emergency parachute, falling slowly to the ground. Measures were taken to improve the GPS systems. The second failure in May, however, led to the drone attempting to deploy its parachute again, only to sever the line...

How the world’s largest cannabis dispensary avoids social media restrictions

Planet 13 is the world’s largest cannabis dispensary. Located in Las Vegas, blocks off the Strip, the facility is the size of a small Walmart. By design, it’s hard to miss. Planet 13 is upending the dispensary model. It’s big, loud and visitors are encouraged to photograph everything. As part of the cannabis industry, Planet 13 is heavily restricted on the type of content it can publish on Instagram, Facebook and other social media platforms. It’s not allowed to post pictures of buds or vapes on some sites. It can’t talk about pricing or product selection on others.   View this post on Instagram   A post shared by Morgan Celeste SF Blogger (@bayareabeautyblogger) on Jan 25, 2020 at 7:54pm PST Instead, Planet 13 encourages its thousands of visitors to take photos and videos. Starting with the entrance, the facility is full of surprises tailored for the ‘gram. As a business, Planet 13’s social media content is heavily restricted a...
