Docker Birthday #4: Thank you Docker Community!

Pақмет сізге, tak, धन्यवाद, cảm ơn bạn, شكرا, mulțumesc, gracias, merci, danke, obrigado, ευχαριστώ, köszönöm, thank you #Docker community! From Des Moines to Santiago de Cuba, Budapest to Tel Aviv and Sydney to Cairo, it was so awesome to see the energy from the community coming together to celebrate and learn about Docker!

We originally planned for 50 Docker Birthday #4 celebrations worldwide with 2,500 attendees. But over 9,000 people registered to attend one of the 152 celebrations across 5 continents! A huge thank you to all the Docker meetup organizers who worked hard to make these celebrations happen and offered Docker beginners the  opportunity to participate in hands on Docker labs.
Join in on the fun!
In case you missed it last week, check out the pics from all of the #DockerBday celebrations including the awesome birthday cakes! Check out the Facebook photo album too! Up for a little more reading? Check out these blog posts from Docker Captains Jonas Rosland and Alex Ellis about their experience mentoring at their local event.
None of this would have been possible without the support (and expertise!) of the 500+ advanced Docker users who signed up as mentors to help attendees learn about Docker by working through the labs we have available.
Here are some of our favorite tweets from the meetups:

In case you weren’t able to attend a local event, all the labs are now available to everyone online here: http://birthday.play-with-docker.com/
About play-with-docker
Play-with-docker (PWD) is a site made by Docker captains Marcos Nils and Jonathan Leibiusky. PWD is a Docker playground which allows you to run Docker commands in a matter of seconds. It gives you the experience of having a free Alpine Linux Virtual Machine in your browser, where you can build and run Docker containers and even create clusters in Docker Swarm Mode. Under the hood DIND or Docker-in-Docker is used to give the effect of multiple VMs/PCs.
Share Your Experience
If you were able to attend a local event, please take a moment to let us know how it went. Here is the participant survey and the mentor survey.
Contribute to Docker Labs
The material used for the Bday 4 meetups was pulled from https://github.com/docker/labs and contains Docker labs and tutorials authored by Docker, and by members of the community.

Learn Docker with our DockerCon 2017 Hands-On Labs

We’re excited to announce that #DockerCon 2017 will feature a comprehensive set of hands-on labs. We first introduced hands-on labs at DockerCon EU in 2015, and they were also part of DockerCon 2016 last year in Seattle. This year we’re offering a broader range of topics that cover the interests of both developers and operations personnel on both Windows and Linux (see below for a full list)
These hands-on labs are designed to be self-paced, and are run on the attendee’s laptop. But, don’t worry, all the infrastructure will be hosted again this year on Microsoft Azure. So, all you will need is a laptop capable of instantiating a remote session over SSH (for Linux) or RDP (for Windows).

We’ll have a nice space set up in between the ecosystem expo and breakout rooms for you to work on the labs. There will be tables and stools along with power and wireless Internet access as well as lab proctors to answer questions. But, because of the way the labs are set up, you could also stop by, sign up, and take your laptop to a quiet spot and work on your own.
As you can tell, we’re pretty stoked on the labs, and we think you will be to.
See you in Austin!
DockerCon 2017 Hands-on Labs

Title

Abstract

#Docker Orchestration

In this lab you can play around with the container orchestration features of Docker. You will deploy a Dockerized application to a single host and test the application. You will then configure Docker Swarm Mode and deploy the same application across multiple hosts. You will then see how to scale the application and move the workload across different hosts easily.

Docker Networking

In this lab you will learn about key Docker Networking concepts. You will get your hands dirty by going through examples of a few basic concepts, learn about Bridge and Overlay networking, and finally learning about the Swarm Routing Mesh.

Modernize .NET Apps – for Devs.

A developer’s guide to app migration, showing how the Docker platform lets you update a monolithic application without doing a full rebuild. You’ll start with a sample app and see how to break components out into separate units, plumbing the units together with the Docker platform and the tried-and-trusted applications available on Docker Hub.

Modernize .NET Apps &8211; for Ops.

An admin guide to migrating .NET apps to Docker images, showing how the build, ship, run workflow makes application maintenance fast and risk-free. You’ll start by migrating a sample app to Docker, and then learn how to upgrade the application, patch the Windows version the app uses, and patch the Windows version on the host &8211; all with zero downtime.

Getting Started with Docker on Windows Server 2016

Get started with Docker on Windows, and learn why the world is moving to containers. You’ll start by exploring the Windows Docker images from Microsoft, then you’ll run some simple applications, and learn how to scale apps across multiple servers running Docker in swarm mode

Building a CI / CD Pipeline in Docker Cloud

In this lab you will construct a CI / CD pipeline using Docker Cloud. You’ll connect your GitHub account to Docker Cloud, and set up triggers so that when a change is pushed to GitHub, a new version of your Docker container is built.

Discovering and Deploying Certified Content with Docker Store

In this lab you will learn how to locate certified containers and plugins on docker store. You&8217;ll then deploy both a certified Docker image, as well as a certified Docker plugin.

Deploying Applications with Docker EE (Docker DataCenter)

In this lab you will deploy an application that takes advantage of some of the latest features of Docker EE (Docker Datacenter). The tutorial will lead you through building a compose file that can deploy a full application on UCP in one click. Capabilities that you will use in this application deployment include:

Docker services
Application scaling and failure mitigation
Layer 7 load balancing
Overlay networking
Application secrets
Application health checks
RBAC-based control and visibility with teams

Vulnerability Detection and Remediation with Docker EE (Docker Datacenter)

Application vulnerabilities are a continuous threat and must be continuously managed. In this tutorial we will show you how Docker Trusted Registry (DTR) can detect known vulnerabilities through image security scanning. You will detect a vulnerability in a running app, patch the app, and then apply a rolling update to gradually deploy the update across your cluster without causing any application downtime.

Docker for Windows Server and Image2Docker

In December we had a live webinar focused on #Windows Server Docker containers. We covered a lot of ground and we had some great feedback – thanks to all the folks who joined us. This is a brief recap of the session, which also gives answers to the questions we didn’t get round to.
Webinar Recording
You can view the webinar on YouTube:

The recording clocks in at just under an hour. Here’s what we covered:

00:00 Introduction
02:00 Docker on Windows Server 2016
05:30 Windows Server 2016 technical details
10:30 Hyper-V and Windows Server Containers
13:00 Docker for Windows Demo &8211; ASP.NET Core app with SQL Server
25:30 Additional Partnerships between Docker, Inc. and Microsoft
27:30 Introduction to Image2Docker
30:00 Demo &8211; Extracting ASP.NET Apps from a VM using Image2Docker
52:00 Next steps and resources for learning Docker on Windows

Q&A
Can these [Windows] containers be hosted on a Linux host?
No. Docker containers use the underlying operating system kernel to run processes, so you can’t mix and match kernels. You can only run Windows Docker images on Windows, and Linux Docker images on Linux.
However, with an upcoming release to the Windows network stack, you will be able to run a hybrid Docker Swarm &8211; a single cluster containing a mixture of Linux and Windows hosts. Then you can run distributed apps with Linux containers and Windows containers communicating in the same Docker Swarm, using Docker’s networking layer.
Is this only for ASP.NET Core apps?
No. You can package pretty much any Windows application into a Docker image, provided it can be installed and run without a UI.
The first demo in the Webinar showed an ASP.NET Core app running in Docker. The advantage with .NET Core is that it’s cross-platform so the same app can run in Linux or Windows containers, and on Windows you can use the lightweight Nano Server option.
In the second demo we showed ASP.NET WebForms and ASP.NET MVC apps running in Docker. Full .NET Framework apps need to use the WIndows Server Core base image, but that gives you access to the whole feature set of Windows Server 2016.
If you have existing ASP.NET applications running in VMs, you can use the Image2Docker tool to port them across to Docker images. Image2Docker works on any Windows Server VM, from Server 2003 to Server 2016.

How does licensing work?
For production, licensing is at the host level, i.e. each machine or VM which is running Docker. Your Windows licence on the host allows you to run any number of Windows Docker containers on that host. With Windows Server 2016 you get the commercially supported version of Docker included in the licence costs, with support from Microsoft and Docker, Inc.
For development, Docker for Windows runs on Windows 10 and is free, open-source software. Docker for Windows can also run a Linux VM on your machine, so you can use both Linux and Windows containers in development. Like the server version, your Windows 10 licence allows you to run any number of Windows Docker containers.
Windows admins will want a unified platform for managing images and containers. That’s Docker Datacenter which is separately licensed, and will be available for Windows soon.
What about Windows updates for the containers?
Docker containers have a different life cycle from full VMs or bare-metal servers. You wouldn’t deploy an app update or a Windows update inside a running container &8211; instead you update the image that packages your app, then just kill the container and start a new container from the updated image.
Microsoft are supporting that workflow with the two Windows base images on Docker Hub &8211; for Windows Server Core and Nano Server. They are following a monthly release cycle, and each release adds an incremental update with new patches and security updates.
For your own applications, you would aim to have the same deployment schedule &8211; after a new release of the Windows base image, you would rebuild your application images and deploy new containers. All this can be automated, so it’s much faster and more reliable than manual patching. Docker Captain Stefan Scherer has a great blog post on keeping your Windows containers up to date.

New Year’s Resolution: Learn Docker

Remember last year when I said the market for Docker jobs was blowing up? Well, it’s more than doubled in the last year. And Swarm is also rising quickly, growing 12829%, almost all of that in the last year. We expect that with our partnership with Microsoft and Windows Docker containers, that this will grow even faster in the next year as .NET developers start to containerize their applications and Windows IT Professionals start porting their infrastructure to Docker. Take a look at this trendline from indeed.com.

So what are you doing to increase your Docker skills? Want a few suggestions?
Whether you’re a developer or more an ops person, a great place to start is the Docker Labs repository, which has currently 28 labs for you to choose from. They range from beginner tutorials, to orchestration workshops, security and networking tutorials, and guides for using different programming languages and developer tools.
Of course there’s also the Docker Documentation, which has a rich set of resources.
At Dockercon 2017 in April, there will be rich set of material for beginners and experts alike, and you will get to meet people from all over the world who are using Docker in their daily lives. Here are just a few things attendees can do at DockerCon:

Learn about Docker from getting started to deep dives into Docker internals from Docker Captains
Take hands-on, self-paced labs that give you practical skills
Learn about the ecosystem of companies that build on Docker in our Expo Hall.
And if you are really passionate about Docker, our recruiting team will have a booth there too, so check out our careers page

You can also take a training course. We have instructor lead trainings all over the world, or you can do a self-paced course.
Or connect with the Docker Community by attending a Docker Event including meetups and webinars. There’s also a Docker Community list you can join that will give you access to a Docker Slack Channel, where you can go for support and discussion.
