Instalando o Docker

WIP

Hello World

Uma vez instalado o docker, execute o seguinte comando:

docker run hello-world

Você receberá o seguinte output:

Hello from Docker.
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker Hub account:
 https://hub.docker.com

# webserver
docker run -d -p 9000:9000 -v $PWD:/usr/src/myapp php:7 php -S 0.0.0.0:9000 -t /usr/src/myapp

Usando o PHP 7 com Dockerfile

docker build -t yourimage .
docker run yourimage

Rodando o MySQL

docker run --name db -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 -d mysql

Docker Compose

docker-compose.yml

web:
  build: .
  ports:
    - "80:80"
  volumes:
    - ./:/usr/src/myapp
  links:
    - db
db:
  image: mysql
  environment:
    - MYSQL_ROOT_PASSWORD=123456
