Docker allows packaging applications with dependencies into standardized units called containers. Containers share the operating system kernel and use layered filesystems, making them lightweight and efficient. Docker is based on open standards and supports all major operating systems, providing portability. Common tools include Docker Engine, Docker Client, Docker Compose, Docker Machine, and Docker Swarm for clustering. Docker simplifies development workflows by allowing applications to always run the same regardless of environment.

1. Build, Ship, Run

2. WHATISDOCKER?
Docker allows you to package an application with all of
its dependencies into a standardized unit for software
development.

4. WHATISDOCKER?
Docker containers wrap up a piece of software in a
complete lesystem 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.

5. LIGHTWEIGHT
Containers running on a single machine all share the
same operating system kernel so they start instantly and
make more e cient use of RAM. Images are constructed
from layered lesystems so they can share common les,
making disk usage and image downloads much more
e cient.

6. OPEN
Docker containers are based on open standards allowing
containers to run on all major Linux distributions and
Microsoft operating systems with support for every
infrastructure.

7. SECURE
Containers isolate applications from each other and the
underlying infrastructure while providing an added layer
of protection for the application.

SOFTWARE
When your app is in Docker containers, you don’t have to
worry about setting up and maintaining di erent
environments or di erent tooling for each language.
Focus on creating new features, xing issues and
shipping software.

15. STARTINGDEVELOPEXISTING
PROJECT
1. try to run the code
2. get an obscure error message
3. Google it
4. try random suggestions you nd on StackOver ow
5. go back to step 1
