Dockerfile ile Apache sunucusunu Ubuntu üzerinde arka plan uygulaması olarak çalıştırmak

24/01/2018 - DOCKER

Bu örneğimizde Apache sunucusunu Ubuntu üzerine kurup, ana sistemden iletişim kuracağız. Buradaki asıl amacımız Apache sunucusunu arka planda sürekli çalışır vaziyette bırakmaktır.

İmaj yaratma


ubuntu@xenial64:~$ docker build -t webserver_img .

Container yaratma


Container port 5000 üzerinden dışarıdan gelen isteklere açık vaziyette.


ubuntu@xenial64:~$ docker run -i -t -d -p 5000:80 --name=webserver_con webserver_img

Container durumu


ubuntu@xenial64:~$ docker ps
