Docker-AspNetCore

A simple Asp.NET Core application wrapped with docker. There are 2 web applications

• CoreApiContainer
• CoreWebContainer

CoreApiContainer is a simple RESTful web api. Call https://[Insert URL and port if necessary]/api/Values CoreWebContainer is a simple web UI using asp.net core and MVC. The home page does a basic print, call the api from the back then a Jquery AJAX call to the web api

The idea behind this architecture is the seperation between the Web UI and the Data access layer that call that accesses the database. This should allow easier updating to the Web UI and data layer and reuse of the data access layer such as a mobile application.

Future Updates

• Configurable ports aka not hard coded
• Environment variables configuration support for docker
• SSL Certificate support
• docker swarm support
• kubernetes support
• Attach database
• Attach InMemory database
• Encryption support
• DNS support

Getting Started

Download and install docker

Build the Docker image

Currently each of the projects have their own Dockerfile to be built independently of each other. Use the command

docker build -t=[tagName] [path]

Where

• [tagName] - the name of the tag to use
• [path] - the path to the code

Run the Docker image

use the command to run the docker image

docker run -p [port]:80 --name [name] [imageTag]

Where

• [port] - the port that the application should use. Currently the default is 80 for both projects which is a problem.
• [name] - name of the container
• [imageTag] - the image tag the application that will run

Issues

Windows 10

There may be a problem when trying to run the docker image if the port has been used previously. Check to see that the application using the port has been stopped and removed. If it has been removed then restart Docker which should clean up the port and allow the container to run. Sample of error

Error starting userland proxy

Other notes

testing some jenkins pipeline builds which were done using openshift.
