Docker is a tool that allows developers to package applications and dependencies into containers that can be run anywhere. The document discusses how Docker eliminates complexity by allowing developers to build, ship and run distributed applications using containers. It provides instructions on how to install Docker and create a simple "hello world" Docker container to demonstrate its basic functionality.

2. What is Docker?
Docker is a tool designed to make
it easier to create, deploy, and run
applications by using containers.
Containers allow a developer to
package up an application with all
of the parts it needs, such as
libraries and other dependencies,
and ship it all out as one package

• docker images # List all images on a Docker host
• docker run # Run an image
• docker ps # List all running and stopped instances
• docker stop # Stop a running instances
• docker rm # Remove an instance
• docker rmi # Remove an image

9. How to install Docker
● uname -r.
● sudo apt-get update
● sudo apt-get install apt-transport-https ca-certificates

12. Creating our first Docker container
● Docker info
● Docker run hello-world
● Docker ps -a
● Docker rm “id”
● Docker rmi “id”

13. Create your Dockerfile, image and
container
●
Nano Dockerfile
– FROM alpine
– CMD [“echo”, “Hello world”]
●
Docker build .
●
docker build -t test/myapp .
●
Docker run –name test “id”

14. Lanjutan, ubah ke dalam shell
script
● Nano Dockerfile
– FROM alpine
– COPY script.sh /script.sh
– CMD [“/script.sh”]
● Nano script.sh
– #! /bin/sc
– Echo Hello world
● Sudo chmod +x script.sh Dockerfile

15. Lanjutan
● Docker rm test
● Docker build .
● Docker run –name test “id”
