Tips for Troubleshooting Apps in Production with Docker Datacenter

If you have been using Docker for some time, after the initial phases of building Dockerfiles and running a container here and there, the real work begins in building, deploying and operating multi-container applications in a production environment.  Are you operationally ready to take your application to production? Docker Datacenter provides an integrated management framework for your Dockerized environment and applications and when coupled with clear strategies in approaching and resolving anomalies, IT ops teams can be assured in successfully operationalizing Docker. Let’s use a sports metaphor to approach troubleshooting: Pre-Game will cover the planning phase for your applications Game Time will cover troubleshooting tools available in Docker Datacenter Post-Game will discuss complementary tools to aid in ongoing insights Pre-Game Whether or not you are sports fan, you can appreciate the importance of the planning out any task. This is no different than what Continue reading…

What’s New in Docker Datacenter with Engine 1.12 – Demo Q&A

Last week we announced the latest release of Docker Datacenter (DDC) with Engine 1.12 integration, which includes Universal Control Plane (UCP) 2.0 and Docker Trusted Registry (DTR) 2.1. Now, IT operations teams can manage and secure their environment more effectively and developers can self-service select from an even more secure image base. Docker Datacenter with Engine 1.12 boasts improvements in orchestration and operations, end to end security (image signing, policy enforcement, mutual TLS encryption for clusters), enables Docker service deployments and includes an enhanced UI. Customers also have backwards compatibility for Swarm 1.x and Compose.   To showcase some of these new features we hosted a webinar where we provided an overview of Docker Datacenter, talked through some of the new features and showed a live demo of solution. Watch the recording of the webinar below:     We hosted Continue reading…

Kick the Tires on Docker Datacenter with DDC-In-A-Box!

Docker Datacenter (DDC) is a powerful solution for managing your containerized applications in a production environment. But what if you could kick the tires of DDC on your laptop with just a single script command? Welcome to DDC-In-A-Box! DDC-In-A-Box is an evaluation script that I wrote which creates a single virtual machine containing Docker Engine, Universal Control Plane (UCP) and Docker Trusted Registry (DTR). The products are licensed using your own license and integrated with each other so you can test out the push/pull integration between UCP and DTR.

Enabling Portability of Workloads And Fighting Lock-In, with Docker

Portability. This is perhaps one of the greatest characteristics of our Docker Containers-as-a-Service platform. After all, in some way it’s the reason why Docker has become as popular as it has today. In just 3 years, we have seen over 2 billion+ Docker Hub pulls, 400,000+ unique Docker Hub users, 200,000+ Dockerized applications and thousands of customers. A large part of the adoption hinges upon portability, making it clear that portability is a huge part of what our users are looking for. It provides the flexibility both developers and IT operations team need in order to succeed at their jobs. But what exactly is portability? At Docker, we define portability as the ability to move workloads across different infrastructure environments, maintaining consistency while enabling Hybrid Cloud and multi-cloud for the enterprise. Portability is the magic that allows enterprises to move Continue reading…

Configuring Load Balancing and Service Discovery with Docker Universal Control Plane

Modern applications are broken up into, and advertised as smaller, decoupled microservices that can be easily scaled across large compute clusters. The microservices approach emphasizes two key architectural considerations: service discovery and load balancing. As developers build their applications to scale, they need to consider and design how each service is being discovered by other services from within or outside the cluster. Additionally, as these services scale horizontally across the cluster, they should be equally utilized for maximum load distribution.

Docker Online Meetup #30: Docker Trusted Registry 1.4.1

We recently hosted a Docker Online Meetup that was all about Docker Trusted Registry. Software Engineer Tony Holdstock-Brown demoed DTR 1.4.1 and discussed the latest features including: – Image deletion and garbage collection – Set up, and manage user accounts, teams, organizations, and repositories from either APIs or through the Trusted Registry user interface – Search, browse, and discover images created by other users through either APIs or through the Trusted Registry UI – New APIs for accessing repositories, account management, indexing, searching, and reindexing – New experimental feature: Docker Trusted Registry now integrates with Docker Content Trust using Notary The recorded video and slide deck from the meetup are available below.

Docker Webinar Q&A: Intro To Docker Security

Today, security is one the biggest topics within the enterprise world and tops the list of enterprise IT initiatives.  As companies have begun to adopt containers within their environments, they have realized the security benefits that come with them as well. Enterprises can now use containers as a means of actually reducing risk within their organization. Containers are isolated from one another, using the same kernel, but are completely unaware that each other exists. This isolation acts a natural security mechanism, making it difficult for hackers to break into environments and gain control of enterprise applications.
