Introduction to Docker
1:13:17 Container and Docker Concepts |
||
|
This section describes container- and Docker basics, contains a few simple demos to spark your interest in Docker containers, and concludes with a brief overview of Linux OS-level virtualization including namespaces, cgroups, and containers. |
||
| Container Concepts | 16:35 | 2020-09-07 |
| What Is Docker | 16:11 | 2020-09-07 |
| Demo: Running Simple Containers | 16:06 | 2020-09-07 |
The Docker commands used in this demo are described in the Basic Docker Commands section. The volume mapping used in Perl and Ansible examples are described in Docker Volumes part of Linux Namespaces section. The complete demo script is here. If you want to recreate the demos or set up your own lab, clone our Docker Examples GitHub repository, install VirtualBox and Vagrant, and execute vagrant up. |
||
| Demo: Running Services in Docker Containers | 12:45 | 2020-09-07 |
The Docker commands used in this demo are described in details in the Basic Docker Commands and Infrastructure-as-Code with Docker Compose sections. The complete demo script is here |

| History of Operating System Virtualization | 11:40 | 2020-09-07 |
This video describes Unix jails and Linux namespaces. For a wider description of compute virtualization technologies watch the Server Virtualization part of Data Center Infrastructure for Networking Engineers webinar. |
||
23:36 Basic Docker Commands |
||
|
In this section you'll learn how to start and kill a Docker container, attach to it, inspect its logs, execute extra commands in parallel with the regular container tasks, and map host directories in container directories. |
||
| Starting, Stopping and Removing Containers | 12:05 | 2020-09-07 |
We used this script when recording this demo. |
||
| Mapping Host Directories into Containers | 5:07 | 2020-09-07 |
We used this script when recording this demo. The container/volume cleanup script is here. |

19:43 Infrastructure-as-Code with Docker Compose |
||
|
Docker Compose is a tool that takes an application infrastructure definition file (in YAML format), and uses Docker API to build or create the required images, networks, and containers. This section provides an overview of Docker Compose and a typical usage scenario. |

||
|
In this section you'll learn the basics of Docker Swarm from the user-facing perspective (creating a swarm, starting container services, and using Docker Stack). Networking aspects of Docker Swarm are covered in Docker Networking webinar. |
