LTP Magazine - The Future Is Docker

Docker && CentOS && Apache

These are the commands that are outlined in the article on how to build, manage, and destroy Docker images and containers.

Build

Copy the sources down and do the build:

$ cd DockerDemo/
$ docker build --rm -t hquinn/dockerdemo .

Images

View images currently on your system:

$ docker images | grep hquinn

Run

Change directory and run container:

$ cd ../CodeProjects/DaveBeingSassy/

$ docker run -d -p 80 --name Project1 --mount type=bind,source="$(pwd)"/app/,target=/var/www/html/ hquinn/dockerdemo

Browse

We need to find the port we want to navigate to:

$ docker ps -a | grep Project1

$ curl http://localhost:<port>

Alternatively, direct your browser to: http://localhost:\

Exec

Enter a shell session in a container:

$ docker exec -it Project1 /bin/bash

Cleanup

Stop a container, delete the container, delete the base image:

# If you're  still in the container's shell:
$ exit

# Otherwise:
$ docker stop Project1

$ docker rm Project1

$ docker rmi hquinn/dockerdemo
