This document discusses containers and Docker. It provides an overview of what Docker is, including that it allows packaging applications and dependencies into standardized units. Deployments with Docker are very fast, taking around 0.5 seconds. Docker containers are more lightweight and portable than virtual machines. The document lists some common Docker commands and provides examples of how companies use Docker for testing environments with multiple versions, microservices architectures, continuous integration with Gitlab and Jenkins, and complete websites deployed with containers.

1. The amazing things we can do with a

I am in a continuous evolution, never satisfied with yesterday, the current Knowledge is not enough… i am not living from the bubbles
emerging because of the courageous swimming man in the deep ocean of ideas; i need go deep, where only a open mind can be free.

2. What is Docker?
● It allow you to package an application with all of its
dependencies into a standardized unit for software
development(code, runtime, system tools, system
libraries – anything you can install on a server).
● Deploys are very fast, usually take 0,5s
● Cross Plataform (“No More! Work on my computer!”)
● Lightweight: containers running on a single machine all
share the same operating system kernel so they start
instantly and make more efficient use of RAM

3. 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.VM
CONTAINERS
Easy Migration/ Faster Deployment/ Faster Restart

4. Some important docker command line:
RUN: create and start a container running a comand inside
STATS: display a live stream of one or more containers' resource usage statistics
COMMIT: create a new image from a container's changes
CP: copy files/folders between a container and the local filesystem
EXEC: run a command in a running container
IMAGES: list images
RESTART: restart a container
START: start a container
STOP: stop a container
it is about 40 commands...
