How to Run a Docker Container on Your Local Machine

I have been working on a hobby project, a nutrition tracking app, to practice the latest continuous integration tools. This post is about dockerizing an angular2 app on your local machine. I skipped the basic definitions about docker, containers, and ci for the sake of simplicity.

Docker Commands

Frequently used docker commands:

Build Docker image:

docker build -t image-name

Run Docker image:

docker run -p 80:80 -it image-name

Stop all docker containers:

docker stop $(docker ps -a -q)

Remove all docker containers:

docker rm $(docker ps -a -q)

Remove all docker images:

docker rmi $(docker images -q)

Port bindings of a specific container :

docker inspect [container-id]

Dockerfile

A dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image. Here's a simple dockerfile that copies the "dist" folder to  /usr/share/nginx/html: 

from nginx
copy dist /usr/share/nginx/html
expose 80

Project Structure

The dockerfile should be located in the root of the project. Here is an example from my project:

How To Run the Docker Container on Your Local Machine

Build 

docker build -t angular-webpack .

Run 

docker run -p 9000:80 -t angular-webpack

This will create a container with the image "angular-webpack" and bind the container’s port 80 to the host machine’s port 9000. After the "docker run -p 9000:80 -it angular-webpack" command, the docker container runs on a linux virtual machine. So we can't run docker natively on windows or a mac. the following properties must be set:

 set environment properties 

set userprofile = c:\users\xxx  --> set your user proile 

set docker_cert_path=%userprofile%\.docker\machine\machines\default

set docker_host=tcp://192.168.99.100 --> find this ip in docker quick start terminal

set docker_machine_name=default

set docker_tls_verify=1

Test: http://192.168.99.100:9000/index.html
