Docker: Form Idea to Dev

Part 1 of 3 part series of webinars on Docker for CloudAcademy. You can read the summary (with link to video) on the CloudAcademy blog: http://cloudacademy.com/blog/docker-containers-how-they-work/

Transcript

1. Docker: From Idea to Dev cloudacademy.com
2. Plan My Goal: Familiarize you with Docker so you can start today Presentation & Demo ~10 minutes for Q & A. Please put your questions in the chat.
3. Hi! I’m Adam Hawkins • Site Reliability Engineering Team Lead at Saltside • Manages ~350 containers in production • 2+ years of Docker experience • “Introduction to Docker” course lecturer • @adman65 • http://blog.slashdeploy.com
4. Docker & Friends
5. ”Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries – anything that can be installed on a server. This guarantees that the software will always run the same, regardless of its environment.” Docker Inc. (2016)
6. Use Cases Build Ship & Run • Development Environment Automation • Managing Data Stores • Cross OS Development • Development & Production Parity
7. Use Cases Build Ship & Run • Infrastructure Standardization • CI Build Isolation • Testing New Software • Distributing New Software
8. Right, But what is it? • Built on top of Linux kernel features like control groups • Isolates process and their resources from others running on a single kernel • Not “light weight” virtualization as often described. This is inaccurate
9. Containers vs VMs Credit: docker.com
10. The Docker Flow
11. Build, Ship, Run $ docker build -t my_org/my_app . $ docker push my_org/my_app $ docker run my_org/my_app
13. The Official Registry & Library • Default place to push & pull images (customizable) • Tons of useful base images in the official library! • Covers 90% of common use cases • User contributed images cover the remaining 10% • Odds are there is a base image for your language (Python, Ruby, Node, Java, Go, and more) • Also images for data stores (Redis, MySQL, MongoDB, and more)
14. Docker Compose • Models multi container applications through a configuration file • Great for development and testing • Can even be used to deploy to staging/ production
15. Docker Machine • Creates Docker hosts • Can create local VMs • Can create cloud instances on AWS/Azures/ etc • Can even create Docker swarms
16. Demo Time! Build a docker image and start a container Play with docker compose Show off misc features/commands
