In a Mac computer download and install all prerequisites below:
* Dotnet Core SDK
* Visual Studio Code
* Node / Angular 
* Git
* Docker

== Starting a new Project ==
=== Creating a new dotnet core web api project ===
 dotnet new webapi -o StaffFinder.Api -n StaffFinder.Api
 cd StaffFinder.Api
 dotnet build
 dotnet run 
When I browse  http://localhost:5000/api/values I can see test json object
 [
 "value1",
 "value2"
 ]
=== Adding docker support ===
==== Create a Dockerfile for an ASP.NET Core application ====
* Create a '''Dockerfile''' in your project folder. '''''it's case sensitive''''' 
* Add the text below to your Dockerfile 
<pre>
FROM microsoft/aspnetcore-build:2.0 AS build-env
WORKDIR /app
# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out

# Build runtime image
FROM microsoft/aspnetcore:2.0
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "StaffFinder.Api.dll"]
</pre>
To make your build context as small as possible add a '''.dockerignore''' file to your project folder and copy the following into it.
 bin\
 obj\

==== Build and run the Docker image ====
In the command prompt and navigate to your project folder.

Use the following commands to build and run your Docker image:
 docker build -t stafffinder.api
 docker run -d -p 8080:80 --name myapp stafffinder.api
Go to [http://localhost:8080/api/values http://localhost:8080/api/values] and same api values are still there.

==== Pushing docker image to Hub (Canister.io) ====
Start by logging in: 
 docker login --username=username cloud.canister.io:5000

The next step is to tag an image that you want to publish:
 docker tag ae5da82730b1 cloud.canister.io:5000/username/my-repo:latest
Notice the format of the tag: <registry-url-including-port>/<username>/<repo-name>:<tag>. 
I used latest as my tag name but you can use any tag name you want.

Finally we just need to push the tag:
 docker push cloud.canister.io:5000/username/my-repo
Note that this command doesn’t include the tag being pushed. It will push all tags in the given repo.

For the deploy I had to do something similar. First, log in to canister.io in the production server:
 docker login --username=username cloud.canister.io:5000
Pull the image:
 docker pull cloud.canister.io:5000/username/my-repo:latest
And finally start it:
 docker run -d --restart=on-failure --name my-service-container cloud.canister.io:5000/username/my-repo:latest
