The document discusses Docker containers and provides instructions for building and running Docker containers. It introduces common Docker concepts like images, containers, Dockerfiles and commands. It explains how to build an image using a Dockerfile, run a container from an image, and lists some important Docker commands like docker pull, docker build, docker run, docker ps. It also provides some best practices for Docker like running as non-root user, having one task per container, and only one foreground process.

1. Docker
Fun with containers & co
Jannis Kirschner

2. ContainerWHAT?

3. But Docker on Windows also works with Linux???

4. One Installation Please!

5. The tiny little problem with VMware….

6. The party’s over at dockerhub

7. Building your own very super duper cool
Docker Container

8. Dockerfile
FROM <os>:<latest> ; Specifies Base Image
MAINTAINER <name> ; Represents Author
RUN <command> ; Executes Command During Build
COPY <src> <dst> ; Copies Files From Host To Container
EXPOSE <port> ; Makes Container Listen On This Port
CMD <command> ; Executes Command After Build
ENV <variablename> <content>; Sets Environment Variables
USER <username> ; Sets Userid/Username

9. Whaletastic commands
# Get container from dockerhub
docker pull <publishername>/<containername>
# Build dockerimage from dockerfile in current directory
docker build –t <imagename>:<version> .
# Run container from dockerimage
docker run --name <containername> <imagename>:<version>
# Show docker processes
docker ps
# Stop docker container
docker stop <containername>
# Remove docker container
docker rm <containername>
# Attach to docker container
docker attach <containername>

10. Most Important takeoffs
Don’t run as root
Containers are volatile
One task - one container
One foreground proccess per container
