‘Docker container’ concepts
Limitations and pitfalls
A short DEMO to start use Docker containers

What does microservice mean?
Microservice is a software architecture style
in which complex applications are composed of
small, independent processes communicating
with each other using language-agnostic APIs
These services are small, highly decoupled and
focus on doing a small task, facilitating a
modular approach to system-building.

Monolithic vs Microservices Architecture

What is the value of Docker containers?
Docker containers wrap up a piece of software
in a complete filesystem that contains everything
it needs to run: code, runtime, system tools,
system libraries – anything you can install on a
server. This guarantees that it will always run the
same, regardless of the environment it is running
in.*

How is this different from virtual machines?
Containers have similar resource isolation and allocation benefits as virtual machines but a
different architectural approach allows them to be much more portable and efficient.
Virtual Machines
Each virtual
machine includes
the application, the
necessary binaries
and libraries and
an entire guest
operating system -
all of which may
be tens of GBs in
size.
Containers
Containers include the
application and all of its
dependencies, but
share the kernel with
other containers.
They run as an isolated process in userspace on the
host operating system. They’re also not tied to any
specific infrastructure – Docker containers run on any
computer, on any infrastructure and in any cloud.

Docker is a system for running applications in lightweight containers that can be deployed across machines. It allows developers to package applications with all dependencies into standardized units for software development. Docker eliminates inconsistencies in environments and allows applications to be easily deployed on virtual machines, physical servers, public clouds, private clouds, and developer laptops through the use of containers.

Docker and containers : Disrupting the virtual machine(VM)Rama Krishna B

This document discusses Docker containers and how they are disrupting virtual machines. It begins with definitions of key terms like virtualization, virtual machines, and hypervisors. It then compares virtual machines to containers, noting that containers are more lightweight and efficient since they share the host operating system and resources, while still providing isolation. The document traces the evolution of containers from early technologies like chroot to modern implementations in Docker. It positions Docker as an open source tool that packages and runs applications in portable software containers. While containers increase efficiency over virtual machines, the document argues both technologies can coexist in cloud environments.

Docker 101 for "The Core of Microservice Architecture"enyert

Docker is a tool that allows applications to run in isolated containers to make them lightweight, portable and able to run anywhere. It uses containers as a method of operating system-level virtualization which isolate Linux systems from each other on a single host. The Docker architecture includes images, containers, the Docker engine and a registry. Containers are ephemeral and any persistent data needs to be mapped to external volumes. A hands-on demo is provided to illustrate Docker's use in launching microservices architectures with containers isolating individual services that can then be independently scaled.

Containers vs. VMs: It's All About the Apps!Steve Wilson

There has been much hype about whether Containers will replace Virtual Machines for use in Cloud architectures. We’ll look at the strengths of each technology and how they apply in real-world usage. By taking a top-down (Application-first) approach to requirements analysis, versus a bottoms-up (Infrastructure-first) approach, we can see how unique architectures will emerge that can balance the needs of Developers, DevOps and corporate IT.

Docker introductionGourav Varma

Docker is a platform for developing and running applications within containers. Containers allow applications to be packaged with all their dependencies and run consistently across different computing environments. The Docker platform includes Docker Engine for running containers, Docker images which are templates for containers, and Docker registries for storing images. When running, a container is isolated from other containers and the host machine. Docker uses a client-server architecture with Docker Engine running as a daemon process and CLI client for interacting with it.

Intro to Docker at the 2016 Evans Developer relations conferenceMano Marks

Building large scale apps traditionally has traditionally meant building large monolithic apps to handle everything. In the new age of the cloud and on premise data centers, increasingly the world is looking to containers and microservices. This allows flexibility and agility. Individual teams can choose the tools they need and be assured they'll work in the environment they want. And it also has implications for how we do developer relations, making it easier to deploy samples without worrying about environment. This session will look at microservices and how they are changing both the enterprise, and our work in developer relations.

DockerCodeister Technolgoies

Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package. By doing so, thanks to the container, the developer can rest assured that the application will run on any other Linux machine regardless of any customized settings that machine might have that could differ from the machine used for writing and testing the code. In a way, Docker is a bit like a virtual machine. But unlike a virtual machine, rather than creating a whole virtual operating system, Docker allows applications to use the same Linux kernel as the system that they’re running on and only requires applications be shipped with things not already running on the host computer. This gives a significant performance boost and reduces the size of the application.

ContainerizationGowtham Ventrapati

Containerization is a operating system virtualization in which application can run in isolated user spaces called containers. Everything an application needs is all its libraries , binaries ,resources , and its dependencies which are maintained by the containers. The Container itself is abstracted away from the host OS with only limited access to underlying resources - much like a lightweight virtual machine (VM)

Microservices Docker @Bonn AgileTimo Derstappen

The document discusses microservices and how Docker can be used with microservices. Some key points about microservices are that they are small, focused services that are highly decoupled and independent. Docker is well-suited for microservices because it allows for lightweight, fast containers that are composable. The document also covers how Docker can be used for development, testing, continuous delivery and production of microservices-based applications.

Dockerfile Jeffrey Ellin

The document discusses Dockerfiles, which are used to build Docker images. A Dockerfile contains instructions like FROM, RUN, COPY, and CMD to set the base image, install dependencies, add files, and define the main process. Images are read-only layers built using these instructions. Dockerfiles can be built locally into images and published to repositories for sharing. Volumes are used to persist data outside the container.

Micro services and ContainersRichard Harvey

Microservices involve breaking up monolithic applications into smaller, independent services that work together. This allows for increased efficiency through scaling individual services as needed, easier updates by updating smaller code bases, and improved stability if one service fails. Containers are well-suited for microservices due to their lightweight nature and ability to easily move workloads.

Microservices, Containers, Docker and a Cloud-Native Architecture in the Midd...Kai Wähner

Microservices are the next step after SOA: Services implement a limited set of functions. Services are developed, deployed and scaled independently. Continuous Integration and Continuous Delivery automate deployments. This way you get shorter time to results and increased flexibility. Containers improve these even more offering a very lightweight and flexible deployment option. In the middleware world, you use concepts and tools such as an Enterprise Service Bus (ESB), Complex Event Processing (CEP), Business Process Management (BPM) or API Gateways. Many people still think about complex, heavyweight central brokers here. However, Microservices and containers are relevant not just for custom self-developed applications, but they are also a key requirement to make the middleware world more flexible, agile and automated. This session discusses the requirements, best practices and challenges for creating a good Microservices architecture in the middleware world. A live demo with the open source PaaS framework CloudFoundry shows how technologies and frameworks such as Java, SOAP / REST Web Services, Jenkins and Docker are used to create an agile software development lifecycle to realize “Middleware Microservices”. It also discusses other modern cloud-native alternatives such as Kubernetes, Docker, Mesos, Mesosphere or Amazon ECS / AWS.

Attack graph generation for micro services architectureAbdul Qadir

Cyber crime is an evolving issue for global enterprises and individuals. Cyber criminals (i.e., attackers) are focusing more on valuable assets and critical infrastructures in a networked system (e.g., enterprise systems and cyber physical systems), which potentially has a high socioeconomic impact in an event of an attack. Security mechanisms (e.g., firewalls) may enhance the security, but the overall in-depth security of the networked system cannot be estimated without a security analysis (e.g., cannot identify security flaws and potential threats). Moreover, attackers may explore an attack surface of the networked system to find vulnerabilities, and exploit them to penetrate through. Therefore, it is important to reduce and continuously change the attack surface based on a security analysis. When remote command injection attacks succeed at the entry points of a cloud (servers exposed to the outside Internet), attackers targeting a specific asset in the cloud will pursue further exploration to find their targets. Attack targets, such as database servers, are often running on separate machines, forcing an extra step for a successful attack.

DockerNeeraj Wadhwa

Containers allow multiple isolated user space instances to run on a single host operating system. Containers are seen as less flexible than virtual machines since they generally can only run the same operating system as the host. Docker adds an application deployment engine on top of a container execution environment. Docker aims to provide a lightweight way to model applications and a fast development lifecycle by reducing the time between code writing and deployment. Docker has components like the client/server, images used to create containers, and public/private registries for storing images.

Building microservices with docker

1. Building Microservices with Docker Roman Melnyk

2. Content Introduction to microservices architecture ‘Docker container’ concepts Limitations and pitfalls A short DEMO to start use Docker containers

3. What does microservice mean? Microservice is a software architecture style in which complex applications are composed of small, independent processes communicating with each other using language-agnostic APIs These services are small, highly decoupled and focus on doing a small task, facilitating a modular approach to system-building.

4. Monolithic vs Microservices Architecture

5. What is the value of Docker containers? Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries – anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in.* _____ * https://www.docker.com/whatisdocker

6. How is this different from virtual machines? Containers have similar resource isolation and allocation benefits as virtual machines but a different architectural approach allows them to be much more portable and efficient. Virtual Machines Each virtual machine includes the application, the necessary binaries and libraries and an entire guest operating system - all of which may be tens of GBs in size. Containers Containers include the application and all of its dependencies, but share the kernel with other containers. They run as an isolated process in userspace on the host operating system. They’re also not tied to any specific infrastructure – Docker containers run on any computer, on any infrastructure and in any cloud.

7. Docker features ●Docker Engine ●Docker Hub ●Docker Trusted Registry ●Docker Machine ●Docker Swarm ●Docker Compose

8. Practical usage single-service stateless host* continuous development and integration for development or testing purposes ___ * stateful service aren’t recommended without attached volumes or volume plugins (Flocker, GlusterFS, Blockbridge)

9. Key concepts ●Images ●Containers ●Volumes

10. Limitations and pitfalls 1.Single process run 2.Performance 3.Natively works only on Linux 4.Security and safety usage base images 5.Client - Host incompatibility

11. Docker is native only to Linux Good news for MS lovers - https://blog.docker.com/2015/08/tp-docker-engine-windows-server-2016/

12. Nearest Future of Docker ●Windows Docker containers ●Hosting docker containers ●Security improvements ●(Who knows?) Support docker on CPU level like virtual machines

Editor's Notes

#4: Properties of microservices architecture: The services are easy to replace Services are organized around capabilities, e.g. user interface front-end, recommendation, logistics, billing, etc Services can be implemented using different programming languages, databases, hardware and software environment, depending on what fits best Architectures are symmetrical rather than hierarchical (producer - consumer) A microservices-based architecture lends itself to a continuous delivery software development process[citation needed] is distinct from a Service-oriented architecture (SOA) in that the latter aims at integrating various (business) applications whereas several microservices belong to one application only
#6: All about applications on backend Every machine uses only partly utilisations VM cluster uses utilisation better but every VM instance grabs part of utilisation for OS and sometimes still need license Containers are more lightweight - just isolated instance of OS
#8: Docker Engine or “Docker” creates and runs Docker containers Docker Hub is our hosted registry service for managing your images. Docker Trusted Registry(DTR) supplies a private dedicated image registry. Docker Registry provides open source Docker image distribution. Docker Machine automates container provisioning on your network or in the cloud. Docker Machine helps you get Docker Engines up and running quickly. Machine can set up hosts for Docker Engines on your computer, on cloud providers, and/or in your data center, and then configure your Docker client to securely talk to them. Docker Swarm is used to host clustering and container scheduling. Docker Swarm pools several Docker Engines together and exposes them as a single virtual Docker Engine. It serves the standard Docker API, so any tool that already works with Docker can now transparently scale up to multiple hosts. Docker Compose defines multi-container applications. Docker Compose allows you to define a application’s components – their containers, configuration, links and volumes – in a single file. Then a single command will set everything up and start your application running.
#10: Images by OOP analogy are classes Containers are instantiated classes Volumes are just mounted volumes on Linux or referenced resources
#11: only one process - make sense since it is microservice even on Linux - containers harms performance. On other OSs harm because it is used as VM Non-Linux application cannot be handled by containers (not yet at least) here is no backward compatibility (dunno why :) )
