Using @Docker in Skytap Cloud | @DevOpsSummit [#DevOps]

Skytap recently announced the availability of a Docker template in the Skytap Cloud Public Template Library

Skytap recently announced the availability of a Docker template in the Skytap Cloud Public Template Library.  Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. This new template allows you to easily experiment with or deploy Docker-based containers within Skytap Cloud.

To illustrate this, we’ll do the following:
1.Create a new Skytap Cloud environment or configuration that is based on this Docker template.
2.Deploy a Docker Ubuntu container and demonstrate a simple use case as described in the Docker User Guide.
3.Create a new Docker Ubuntu container and configure it to contain a MongoDB instance and then run it as described in the Docker Examples web page

Create a Skytap Cloud Environment Based on the Docker Template

Once you log into your Skytap Cloud account, navigate to the Template’s tab and search for “Docker” within the “Skytap” templates.


Next, select the drop-down menu associated with the template and choose “Deploy as New Configuration”:


Once the Docker configuration is deployed, start it, get a desktop and log in as user “skytap” to begin interacting with it.

Since our interaction with Docker will be via a command line, open a Terminal window:



Deploy a Docker Ubuntu Container and Say “Hello World”

Now we will use the “docker run” command to launch a Docker Ubuntu container and echo “Hello World”.  Note that the docker command must be run as a super user, so we will prefix the command with “sudo”, which will require an initial authentication step:


After authenticating, the “docker” command executes and, not finding the required specified image locally, pulls the Ubuntu 14.04 image from the “Docker Hub” public repository and runs it with the specified “/bin/echo ‘Hello World’” command.

Create and Run a MongoDB Docker Container

In this example, we will create a new Docker container that is configured with the MongoDB application and then we will run it and interact with MongoDB on the Docker container.
Creation of a Docker container can be automated using a “Dockerfile”.  While we could create the required Dockerfile for this exercise using a text editor, instead we will use the “wget” command to retrieve the example Dockerfile from the Docker Examples document repository.



Now we can issue the “docker build” command to build the MongoDB Docker image and save it in our local Docker repository:


Our MongoDB Docker container has been created and stored locally with the tag “mongodb-repo.

Prior to deploying and interacting with our MongoDB Docker container, we need to install the MongoDB client software on our working virtual machine:


We can deploy and use our newly created MongoDB Docker container with the “docker run –d –p 27017 –name mongo_01 mongodb-repo” command.


In this “docker run” command, the –d argument runs the container in the background as a daemon.  The –p argument maps the default MongoDB port 27017 to a port on our working virtual machine. The –name argument provides a name for the Docker container to be run.

We can determine the port on our working virtual machine to which the default mongodb port of 27017 has been mapped by issuing the “docker ps” command:


Here we can see that port 49153 on our working virtual machine has been mapped to port 27017 on our Docker “mongo_01” container.  With this information we can connect to the MongoDB instance running in our Docker container with the “mongo localhost:49153” command:


We can see that the mongo client on our working virtual machine has successfully connected to the MongoDB process on our Docker container.  Additionally we can successfully interact with our Dockerized MongoDB instance.

Summary
We’ve created a Docker environment in Skytap Cloud from the Docker template in the Skytap Cloud Public Template Library and then deployed a simple Docker “Hello World” application.  We then created a more complex Dockerized instance of MongoDB in our Skytap Cloud Docker environment and were able to run, connect to, and interact with it.

The principles demonstrated in these Docker exercises can easily be expanded further into more complex or interesting scenarios based on your requirements.

@DevOpsSummit Stories
All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the works because of misaligned incentives.
Join IBM November 2 at 19th Cloud Expo at the Santa Clara Convention Center in Santa Clara, CA, and learn how to go beyond multi-speed it to bring agility to traditional enterprise applications. Technology innovation is the driving force behind modern business and enterprises must respond by increasing the speed and efficiency of software delivery. The challenge is that existing enterprise applications are expensive to develop and difficult to modernize. This often results in what Gartner calls "Bimodal IT," where business struggle to apply modern tools and practices to traditional monolithic applications. But these existing assets can be modernized and made more efficient without having to be completely overhauled. By leveraging methodologies like DevOps and agile, alongside emerging technologies like cloud-native services and containerization, traditional applications and teams can be ...
Translating agile methodology into real-world best practices within the modern software factory has driven widespread DevOps adoption, yet much work remains to expand workflows and tooling across the enterprise.

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm.

In recent years, containers have taken the world by storm. Companies of all sizes and industries have realized the massive benefits of containers, such as unprecedented mobility, higher hardware utilization, and increased flexibility and agility; however, many containers today are non-persistent. Containers without persistence miss out on many benefits, and in many cases simply pass the responsibility of persistence onto other infrastructure, adding additional complexity.

New competitors, disruptive technologies, and growing expectations are pushing every business to both adopt and deliver new digital services. This ‘Digital Transformation’ demands rapid delivery and continuous iteration of new competitive services via multiple channels, which in turn demands new service delivery techniques – including DevOps. In this power panel at @DevOpsSummit 20th Cloud Expo, moderated by DevOps Conference Co-Chair Andi Mann, panelists will examine how DevOps helps to meet the demands of Digital Transformation – including accelerating application delivery, closing feedback loops, enabling multi-channel delivery, empowering collaborative decisions, improving user experience, and ultimately meeting (and exceeding) business goals.
DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the ‘digital exhaust’ from the delivery toolchain, "pervasive" and "cognitive" computing, APIs and services, mobile devices and applications, the Internet of Things, and now even blockchain.

The goal of Continuous Testing is to shift testing left to find defects earlier and release software faster. This can be achieved by integrating a set of open source functional and performance testing tools in the early stages of your software delivery lifecycle. There is one process that binds all application delivery stages together into one well-orchestrated machine: Continuous Testing. Continuous Testing is the conveyor belt between the Software Factory and production stages. Artifacts are moved from one stage to the next only after they have been tested and approved to continue. New code submitted to the repository is tested upon commit. When tests fail, the code is rejected. Subsystems are approved as part of periodic builds on their way to the delivery stage, where the system is being tested as production ready. The release process stops when tests fail. The key is to shift test ...
