5. Introducing Docker

6. What is Docker?
Docker là gì?

7. So what Docker is?
Docker allows you to package an application with
all of its dependencies into a standardized unit for
software development.
Docker containers wrap up a piece of software in a
complete filesystem 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.

9. What is a Container?
Container là gì??
is a set of processes which have been
isolated together by the Linux kernel

10. Why Docker?

15. Developer: Build Once, Run
Anywhere
●
A clean, safe, hygienic and portable runtime environment for your app.
●
No worries about missing dependencies, packages and other pain
points during subsequent deployments.
●
Run each app in its isolated container.
●
Automate testing, integration, packaging...anything you can script
●
Reduce/eliminate concerns about compatibility on different platforms,
either your own or your customers.
●
Install replay and reset of image snapshots.
●
Almost no overhead (think about VM).

16. DevOps: Configure Once, Run
Anything
●
Make the entire lifecycle more efficient, consistent, and repeatable.
●
Increase the quality of code produced by developers.
●
Eliminate inconsistencies between development, test, production,
and customer environments.
●
Support segregation of duties.
●
Significantly improves the speed and reliability of continuous
deployment and continuous integration systems.
●
Because the containers are so lightweight, address significant
performance, costs, deployment, and portability issues normally
associated with VMs.

18. Dockerfile
A Dockerfile is a text document that contains all the
commands a user could call on the command line to
assemble an image.

30. How to create Docker container?
Làm th nào đ t o ra Dockerế ể ạ
container?
$ docker run [IMAGE_ID]
$ docker run --name d7memcache -d [IMAGE_ID]
Where “d7memcache” is the name of the container and
“-d” is to tell Docker to run the “d7memcache” container in
background and “[IMAGE_ID]” is the Docker image that we
want to load in the container.

31. How to SSH in Docker container?

Where “db_d7_vietnam” is the name of the container and “123456” is root password and
“mysql:5.6” is the Docker image.
$ docker run --name web_apache2 --link db_d7_vietnam:db_d7_vietnam -d -p 49980:80 -v
/home/gerald/Web/drupal7/www:/var/www/html [WEB_IMAGE_ID]
Where “web_apache2” is the name of the web app and “49980” is the http port mapped to port 80
of the web container and “/home/gerald/Web/drupal7/www” is the location of Drupal project and
“/var/www/html” is the mount point inside Docker container and “[WEB_IMAGE_ID]” is the ID of
Docker image containing Apache and PHP stuff.

containers?
# To list running containers
$ docker ps
# To list all containers
$ docker ps -a
