DockerCon 2020: The AWS Sessions

Last week we announced Docker and AWS created an integrated and frictionless experience for developers to leverage Docker Compose, Docker Desktop, and Docker Hub to deploy their apps on Amazon Elastic Container Service (Amazon ECS) and Amazon ECS on AWS Fargate. On the heels of that announcement, we continue the latest series of blog articles focusing on developer content that we are curating from DockerCon LIVE 2020, this time with a focus on AWS. If you are running your apps on AWS, bookmark this post for relevant insights for easy access in one place.

As more developers adopt and learn Docker, and as more organizations are jumping head-first into containerizing their applications, AWS continues to be the cloud of choice for deployment. Earlier this year Docker and AWS collaborated on open specification and as mentioned on the Docker blog by my colleague Chad Metcalf, deploying straight from Docker to AWS has never been easier. It’s just another step to constantly put ourselves in the shoes of you, our customer, the developer.

The replay of these three sessions on AWS is where you can learn more about container trends for developers, adopting microservices and building and deploying multi-container Continue reading

DockerCon 2020: The Microsoft Sessions

This is the second post of our series of blog articles focusing on the key developer content that we are curating from DockerCon LIVE 2020. Increasingly, we are seeing more and more developers targeting Microsoft architectures and Azure for their containerized application deployments. Microsoft has always had a rich set of developer tools including VS Code and GitHub that work with Docker tools. 

One of the biggest developments for developers using Windows 10 is the release of WSL 2 (Windows Subsystem for Linux). Instead of using a translation layer to convert Linux kernel calls into Windows calls, WSL 2 now offers its own isolated Linux kernel running on a thin version of the Hyper-V hypervisor. Check out Simon Ferquel’s session on WSL 2 as well as Paul Yuknewicz’s session on apps running in Azure. Be sure to check out these valuable sessions on using Docker with Microsoft tools and technologies.

DockerCon 2020: Top Rated Sessions – The Fundamentals

Of all the sessions from DockerCon LIVE 2020, the Best Practices + How To’s track sessions received the most live views and on-demand views. Not only were these sessions highly viewed, they were also highly rated. We thought this would be the case based on the fact that many developers are learning Docker for this first time as application containerization is experiencing broad adoption within IT shops. In the recently released 2020 Stack Overflow Developer Survey Docker ranked as the #1 most wanted platform. The data is clear…developers love Docker!

This post begins our series of blog articles focusing on the key developer content that we are curating from DockerCon. What better place to start than with the fundamentals. Developers are looking for the best content by the top experts to get started with Docker. These are the top sessions from the Best Practices + How To’s track.

Peter’s session was the top session based on views across all of the tracks. He does an excellent job focusing on the fundamentals of containers and how to go from code to cloud. This session covers getting Docker installed, writing Continue reading

Deploy Stateful Docker Containers with Amazon ECS and Amazon EFS

At Docker, we are always looking for ways to make developers’ lives easier either directly or by working with our partners. Improving developer productivity is a core benefit of using Docker products and recently one of our partners made an announcement that makes developing cloud-native apps easier.

AWS announced that its customers can now configure their Amazon Elastic Container Service (ECS) applications deployed in Amazon Elastic Compute Cloud (EC2) mode to access Amazon Elastic File Storage (EFS) file systems. This is good news for Docker developers who use Amazon ECS. It means that Amazon ECS now natively integrates with Amazon EFS to automatically mount shared file systems into Docker containers. This allows you to deploy workloads that require access to shared storage such as machine learning workloads, containerizing legacy apps, or internal DevOps workloads such as GitLab, Jenkins, or Elasticsearch. 

The beauty of containerizing your applications is to provide a better way to create, package, and deploy software across different computing environments in a predictable and easy-to-manage way. Containers were originally designed to be stateless and ephemeral (temporary). A stateless application is one that neither reads nor stores information about its state from one time that it is run Continue reading

Hack Week: How Docker Drives Innovation from the Inside

Since its founding, Docker’s mission has been to help developers bring their ideas to life by conquering the complexity of app development. With millions of Docker developers worldwide, Docker is the de facto standard for building and sharing containerized apps. 

So what is one source of ideas we use to simplify the lives of developers? It starts with being a company of software developers who builds products for software developers. One of the more creative ways Docker has been driving innovation internally is through hackathons. These hackathons have proven to be a great platform for Docker employees to showcase their talent and provide unique opportunities for teams across Docker’s business functions to come together. Our employees get to have fun while creating solutions to problems that simplify the lives of Docker developers.

At Docker, our engineers are always looking for ways to improve their own workflows so as to ship quality code faster. Hack Week gives us a chance to explore the boundaries of what’s possible, and the winning ‘hacks’ make their way into our products to benefit our global developer community.

-Scott Johnston, Docker CEO

With that context, let’s break down how Docker runs employee hackathons. Docker is Continue reading

AWS IoT Greengrass 1.10 Now Supports Docker Containers

On November 25, 2019, AWS announced the release of AWS IoT Greengrass 1.10 allowing developers to package applications into Docker container images and deploy these to edge devices. Deploying and running Docker containers on AWS IoT Greengrass devices enables application portability across development environments, edge locations, and the cloud. Docker images can easily be stored in Docker Hub, private container registries, or with Amazon Elastic Container Registry (Amazon ECR).

Docker is committed to working with cloud service provider partners such as AWS who offer Docker-compatible on-demand container infrastructure services for both individual containers as well as multi-container apps. To make it even easier for developers to benefit from the speed of these services but without giving up app portability and infrastructure choice, Docker Hub will seamlessly integrate developers’ “build” and “share” workflows with the cloud “run” services of their choosing.

“Docker and AWS are collaborating on our shared vision of how workloads can be more easily deployed to edge devices. Docker’s industry-leading container technology including Docker Desktop and Docker Hub are integral to advancing developer workflows for modern apps and IoT solutions. Our customers can now deploy and run Docker containers seamlessly on AWS IoT Greengrass devices, enabling development Continue reading

Momentum is building for edge computing

With the rise of the Internet of Things (IoT) combined with global rollout of 5G (Fifth-generation wireless network technology), a perfect storm is brewing that will see higher speeds, extreme lower latency, and greater network capacity that will deliver on the hype of IoT connectivity.

And industry experts are bullish on the future. For example, Arpit Joshipura, The Linux Foundation’s general manager of networking, predicts edge computing will overtake cloud computing by 2025. According to Santhosh Rao, senior research director at Gartner, around 10% of enterprise-generated data is created and processed outside a traditional centralized data center or cloud today. He predicts this will reach 75% by 2025.

Back in April 2019, Docker and Arm announced a strategic partnership enabling cloud developers to build applications for cloud, edge, and IoT environments seamlessly on the Arm® architecture. We carried the momentum with Arm from that announcement into DockerCon 2019 in our joint Techtalk, where we showcased cloud native development on Arm and how multi-architecture containers with Docker can be used to accelerate Arm development.

As part of our strategic partnership, Docker will Continue reading

Powering Docker App: Next Steps for Cloud Native Application Bundles (CNAB)

Last year at DockerCon and Microsoft Connect, we announced the Cloud Native Application Bundle (CNAB) specification in partnership with Microsoft, HashiCorp, and Bitnami. Since then the CNAB community has grown to include Pivotal, Intel, DataDog, and others, and we are all happy to announce that the CNAB core specification has reached 1.0.

We are also announcing the formation of the CNAB project under the Joint Development Foundation, a part of the Linux Foundation that’s chartered with driving adoption of open source and standards. The CNAB specification is available at Docker is working hard with our partners and friends in the open source community to improve software development and operations for everyone.

Docker’s Implementation of CNAB — Docker App

Docker was one of the first to implement the CNAB specification with Docker App, our reference implementation available on GitHub. Docker App can be used to both build CNAB bundles for Docker Compose (which can then be used with any other CNAB client), and also to install, upgrade, and uninstall any other CNAB bundle.

It also forms the underpinnings of application templates in Docker Desktop Enterprise. With Docker App, we are making CNAB-compliant applications as easy to use Continue reading
