Learn About Modern Apps with Docker at VMworld 2019

The Docker team will be on the show floor at VMworld the week of August 25. We’ll be talking about the state of modern application development, how to accelerate innovation efforts, and the role containerization and Docker play in powering these initiatives. 
Come by booth #1969 at VMworld to check out the latest developments in the Docker platform and learn why over 1.8 million developers build modern applications on Docker, and why over 800 enterprises rely on Docker Enterprise for production workloads. 
At VMworld, we’ll be talking about:

What’s New in Docker Enterprise 3.0

Docker Enterprise 3.0 shipped recently, making it the first and only desktop-to-cloud container platform in the market that lets you build and share any application and securely run them anywhere – from hybrid cloud to the edge. At VMworld, we’ll have demos that shows how Docker Enterprise 3.0 simplifies Kubernetes with the Docker Kubernetes Service (DKS) and enables companies to more easily build modern applications with Docker Desktop Enterprise and Docker Application.

Accelerating Your Journey to the Cloud

Everyone is talking about moving workloads to the cloud to drive efficiencies and simplify ops, but many existing applications that power Continue reading

IDG Contributor Network: IoT-enabled shipping containers sail the high seas improving global supply chains.

Global trade flows through shipping containers. Manufacturers depend on them to get raw materials in time and to ship finished products to market. IoT is being applied to monitor containers and make sure that their contents aren’t damaged or stolen.Inter-modal containers Containers have standardized dimensions, which lets transporters easily ship, stack and store them. There are over twenty million containers in motion right now. Containers are pre-filled which reduces the time that trucks need to get loaded. Their standard size allows them to be easily transferred between trucks, planes, ships and trains.Global supply chains based on containers enable manufacturers to minimize their costs with ‘just-in-time’ inventory. This makes it important to track containers’ location and the condition of their contents.To read this article in full, please click here

Reconstructing the Join Command for Kubeadm

If you’ve used kubeadm to bootstrap a Kubernetes cluster, you probably know that at the end of the kubeadm init command to bootstrap the first node in the cluster, kubeadm prints out a bunch of information: how to copy over the admin Kubeconfig file, and how to join both control plane nodes and worker nodes to the cluster you just created. But what if you didn’t write these values down after the first kubeadm init command? How does one go about reconstructing the proper kubeadm join command?

Fortunately, the values needed for a kubeadm join command are relatively easy to find or recreate. First, let’s look at the values that are needed.

Here’s the skeleton of a kubeadm join command for a control plane node:

kubeadm join <endpoint-ip-or-dns>:<port> \
--token <valid-bootstrap-token> \
--discovery-token-ca-cert-hash <ca-cert-sha256-hash> \
--control-plane \
--certificate-key <certificate-key>

And here’s the skeleton of a kubeadm join command for a worker node:

kubeadm join <endpoint-ip-or-dns>:<port> \
--token <valid-bootstrap-token> \
--discovery-token-ca-cert-hash <ca-cert-sha256-hash> \

As you can see, the information needed for the worker node is a subset of the information needed for a control plane node.

Here’s how to find or recreate all the various pieces of information you need:

Cloudflare Global Network Expands to 193 Cities

Cloudflare Global Network Expands to 193 Cities

Cloudflare’s global network currently spans 193 cities across 90+ countries. With over 20 million Internet properties on our network, we increase the security, performance, and reliability of large portions of the Internet every time we add a location.

Cloudflare Global Network Expands to 193 Cities

Expanding Network to New Cities

So far in 2019, we’ve added a score of new locations: Amman, Antananarivo*, Arica*, Asunción, Bengaluru, Buffalo, Casablanca, Córdoba*, Cork, Curitiba, Dakar*, Dar es Salaam, Fortaleza, Göteborg, Guatemala City, Hyderabad, Kigali, Kolkata, Male*, Maputo, Nagpur, Neuquén*, Nicosia, Nouméa, Ottawa, Port-au-Prince, Porto Alegre, Querétaro, Ramallah, and Thessaloniki.

Our Humble Beginnings

When Cloudflare launched in 2010, we focused on putting servers at the Internet’s crossroads: large data centers with key connections, like the Amsterdam Internet Exchange and Equinix Ashburn. This not only provided the most value to the most people at once but was also easier to manage by keeping our servers in the same buildings as all the local ISPs, server providers, and other people they needed to talk to streamline our services.

This is a great approach for bootstrapping a global network, but we’re obsessed with speed in general. There are over five hundred cities in the world with over one million inhabitants, but only a handful Continue reading

Developing Docker-Powered Applications on Windows with WSL 2

This is a guest post from Docker Captain Antonis Kalipetis, a Senior Software Engineer at e-food — the leading online food delivery service in Greece. He is a Python lover and developer and helps teams embrace containers and improve their development workflow. He loves automating stuff and sharing knowledge around all things containers, DevOps and developer workflows. You can follow him on Twitter @akalipetis. WSL 2 (or Windows Subsystem for Linux version 2) is Microsoft’s second take on shipping a Linux Kernel with Windows. The first version was awesome as it translated Linux system calls to the equivalent Windows NT call in real time. The second version includes a full fledged virtual machine It was only natural that Docker would embrace this change and ship a Docker Desktop for Windows version that runs on WSL 2 (WSL 1 had issues running the Docker daemon). This is still a Technical Preview, but after using it for a couple of days, I’ve completely switched my local development to take advantage of it and I’m pretty happy with it. In this blog, I’ll show you an example of how to develop Docker-powered applications using the Docker Desktop WSL 2 Tech Preview.
