Tutorial: Docker 101

This is a quick Docker 101 course with tasks. The Live folder is just a live demo i made to present before making the students perform the tasks

/Live is Java with dropwizared in docker /SimpleNancy is C# in docker /nodedock is node in docker /springboot is Java with springboot in docker

---

Stuff needed:

1. OSX/Windows: download docker-toolbox https://www.docker.com/docker-toolbox (docker, docker-compose, virtualbox)
2. Install node,java,.net, or a language you would like to work with

---

Tasks:

Download code: git clone https://github.com/Roykk/dockerdag

Create a docker machine

	docker-machine create --driver virtualbox myDocker
	docker-machine env myDocker
	eval $(docker-machine env myDocker)

run docker-machine ip and note your ip-address!

Task 1:

#####Get to know docker: Create a dockerfile, build a docker imageand start a container.

3 different webapps is created in different languages, dockerize as many as you can. All of them has a solutions folder, this is a dockerfile which can be used in futher in task2.

1. Springboot (Java)

    cd springboot
    mvn install
    java -jar  -Djava.security.egd=file:/dev/./urandom target/springboot-1.0-SNAPSHOT.jar
    curl mot localhost:8081/ping  (or use your browser browser)
   

2. NodeDock (Node)

    cd nodeDock
    npm install
    node nodeapp.js
    curl localhost:8082/ping (or use your browser browser)
   

3. SimpleNancy (.NET , created just as showcase, to show .net in docker and linux)

    Build and run it the .net way
    curl localhost:8082/ping
   

all web appliacations has a solutions folder. Please take a peak there if you are stuck

Task 2

Get to know docker-compose: Make services talk together! Java --> Node --> MongoDB

	Go to /dockerdag, and look at docker-compose.yml
	docker-compose up
	curl localhost:8081/count (or use your browser browser)

Try to complete the docker-compose.yml!

(PS. please use dockerfile in solutions, if you have not completed them yourself)

Task 3

Challenge yourself, play around with Docker

	DO you have your own project you want to dockerize??
	Do you want to test you docker in the cloud?
	Play with docker!
