Cake.Net. Useful scripts for AngularJS, dotnet core, docker application

There is a great cross-platform build automation tool - Cake.Net.

I started using it and created some useful scripts to Release and Publish new version of application.

I am using AngularJS as frontend framework, asp net core (dotnet core) as backend framework, git as source system and docker to deploy and run application on remote server.

So it is a small cake script to release a new version of application:

#addin "Cake.Docker"
#addin "Cake.FileHelpers"

// Release: ./build.sh -t Release "-packageVersion=x.x.x.x"
// Publish: ./build.sh -t Publish "-packageVersion=x.x.x.x" "-env=one"
// Delete release: ./build.sh -t Delete "-packageVersion=x.x.x.x"
var target = Argument<string>("target");
var version = Argument<string>("packageVersion");

public class Settings
{
    public string SshAddress;
    public string SshPort;
    public string HomePath;
}

Settings sets;

Task("SelectEnvironment")
    .Does(()=>{
        var env = Argument<string>("env");
        var environments = new Dictionary<string, Settings> {
            ["one"] = new Settings {
                SshAddress = "root@66.66.66.66",
                SshPort = "22",
                HomePath = "/root/Templates"
            },
            ["two"] = new Settings{
                SshAddress = "root@99.99.99.99",
                SshPort = "26",
                HomePath = "/home/Templates"
            }
        };

I am running service using docker compose like:

version: '2'
services:
    ContainerName:
        image: ContainerName:x.x.x.x

Thanks.
