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 you would do for your applications. Health checks are a great way to provide a deeper level of insight into how your application is performing. Since Docker 1.12 there is a new HEALTHCHECK directive. We can use this directive to signal to the Docker Engine whether or not the application is healthy.

There are a two ways to implement the HEALTHCHECK Continue reading

Why CISOs succeed and why they leave

Earlier this year, ESG and the Information Systems Security Association (ISSA) published a research report titled, The State of Cyber Security Careers. The report was based on a survey of 437 cybersecurity professionals, the clear majority of which were ISSA members.Two-thirds of these cybersecurity professionals worked at an organization that employed a CSO or CISO. These individuals were then asked to identify the most important qualities that make a successful CISO. Here is a sample of the results: 50% of respondents said strong leadership skills were most important 47% of respondents said strong communication skills were most important 30% of respondents said a strong relationship with business executives was most important 29% of respondents said a strong relationship with the CIO and other members of the IT leadership team was most important 23% of respondents said strong management skills were most important Based upon this list, it’s clear that successful CISOs need to be strong business people who can work with business and IT executives. This is an important consideration since many security professionals are deeply rooted in the technology rather than the business aspects of infosec.To read this article in full or to leave a comment, please Continue reading

Learn Docker with More Hands-On Labs

Docker Labs is a rich resource for technical folks from any background to learn Docker. Since the last update on the Docker Blog, three new labs have been published covering Ruby, SQL Server and running a Registry on Windows. The self-paced, hands-on labs are a popular way for people to learn how to use Docker for specific scenarios, and it’s a resource which is growing with the help of the community.

Docker hands-on labs

New Labs

  • Ruby FAQ. You can Dockerize Ruby and Ruby on Rails apps, but there are considerations around versioning, dependency management and the server runtimes. The Ruby FAQ walks through some of the challenges in moving Ruby apps to Docker and proposes solutions. This lab is just beginning, we would love to have your contributions.
  • SQL Server Lab. Microsoft maintain a SQL Server Express image on Docker Hub that runs in a Windows container. That image lets you attach an existing database to the container, but this lab walks you through a full development and deployment process, building a Docker image that packages your own database schema into an image.
  • Registry Windows Lab. Docker Registry is an open-source registry server for storing Docker images, which you can run Continue reading

IDG Contributor Network: Digital transformation: Not your grandfather’s bank

Changes in the way we do business with banks are rarely initiated by banks themselves. Instead, banks are often forced to adapt because of technological advancements that are shifting social culture and customer expectations.

Yet all too often, banks do not act on those insights and pass up the opportunity to create a great customer experience.To read this article in full or to leave a comment, please click here

Petcube Play: An in-home camera for watching your pets do stuff

Most people enjoy pets. Some enjoy them enough where they want to do things with them when they’re away from their house. That’s the idea behind the Petcube Play, an in-home camera that connects to your Wi-Fi network so you can watch your pets while you’re at work or not at home. In addition to the live camera feed, it includes a two-way audio speaker for speaking to your pet (“Max! Get off the couch!”) and a red laser-pointer that you can move around by pointing to locations on your smartphone’s display and hope that the cat or dog starts to chase it – hilarity ensues.The Petcube itself is a cube – it’s about the size of a slightly larger Rubik’s Cube puzzle game. It doesn’t have a battery, so the first thing you need to figure out when placing the Petcube Play is to make sure it’s close enough to a power adapter. The instructions warn about making sure your pet doesn’t chew the power cable. It also comes with a small tripod attachment that you can screw into the bottom of the Petcube if you’re looking to place it higher than a table or desk. Continue reading
