Deploying an ASP.NET web site to a remote VPS with Jenkins - asp.net

I am just starting to get my head wrapped around continuous deployment with Jenkins, but I am running into some roadblocks and I haven't really found very many good, definitive resources on the topic in regards to ASP.NET applications.
I have set up a local build server than successfully pulls down code from a SVN repo, and builds it OK with MSBuild. This works well so far, but now I'd like to automate pushing this compiled code to a development server.
My problem is this - from what I gather based on what I read (which may be an incorrect assumption...) is that the staging server is typically within the same network as the build server, meaning you can share network resources, servers, etc.
In my case, I want to run the Jenkins server on a remote VPS, then deploy to other remote VPSes (so, essentially individual isolated machines communicating with each other).
I have seen alot of terms, but I am very new in my Sys Admin / DevOps type skills.
So, my question is this:
Is it even possible to, using Jenkins on a VPS, to then deploy to any particular server I choose? (I have full access to all of them, so if its a security thing, I can fix that... but they are not within the same network/domain)
What is the method to achieve this? I've seen xcopy, Web Deployment Packages (msdeploy), batch scripts, etc. mentioned, but not really a guidance behind what to use in what situations. Are any of these methods useful to achieve my goal?
Thanks for any help or guidance!

How is your Powershell? ;) You should check out psake.
psake is a build automation tool written in PowerShell. It avoids the
angle-bracket tax associated with executable XML by leveraging the
PowerShell syntax in your build scripts. psake has a syntax inspired
by rake (aka make in Ruby) and bake (aka make in Boo), but is easier
to script because it leverages your existent command-line knowledge.
psake is pronounced sake – as in Japanese rice wine. It does NOT rhyme
with make, bake, or rake.

You can deploy your files to the target server through SSH. Jenkins do support transfers through SSH. All you need to do is setting up a SSH server ex : CopSSH and a user account with admin permissions. and configuring the Jenkins to transfer through SSH.
Create host configurations in the main Jenkins configuration
Add an SSH Server
Add the public key to the remote server (the build server)
Click "Test Configuration"
Save
Configure a job to Publish Over SSH (Post Build Action)
Add Transfer Set.
Refer Publish Over SSH For More details

Why do we need to deploy a meteor app instead of just starting it?

As we all know, we can run a meteor app by just typing meteor in a terminal.
By default it will start a server and use port 3000.
So why do I need to deploy it using MUP etc.
I can configure it to use port 80 or use nginx to route to port 80 for the app. So the port is not the point.
Edit:
Assume meteor is running on a VPS or cloud server with public IP address, not a personal computer.
MUP does a few extra things you can do yourself:
it 'bundles' the code into a single file, using meteor build bundle
the javascript is one file, and css another; it's minified, and obfuscated so it's smaller and faster to load, and less easy to decipher on the client.
some packages are also meant to be removed when running in production. For example meteorToys, the utility toolset to look up collections and much more, is not bundled into the production bundle, as per the instructions in its package. This insures you don't deploy code with security vulnerabilities (Meteor toys basically opens up client side delete / updates etc... if you're not careful)
So, in short, it installs a minimal version of your site, making sure that what's meant for development only doesn't get push to a production environment.
EDIT: On other reason to do this, is that you don't need all the Meteor build tools on your production server; that can add up to a lot of stuff, especially if you keep caches going for a while...
I believe it also takes care of hooking up to a remote MongoDB Instance (at least it used to be the case on the free meteor site) which is more scalable and fault tolerant than running on the same instance as the web server, as well as provision storage etc... if needed.
basically, to deploy a Meteor app yourself manually, you need to:
on your dev box:
meteor build bundle your app to a tar file (using the architecture flag corresponding to the OS you will use)
on the server:
install node v0.10 (or whatever is the current version of node required by Meteor)
you might have to install Fiber#1.0.5 (but I believe this is now part of meteor install already)
untar the bundle, get into bundle/programs/server/ and run npm install
run the server with node main.js in the bundle folder.
The purpose of deploying an application is that you are situating your project on hardware outside of your local machine. For example if you deploy an application on Heroku app you create a repository on heroku's systems and that code based is used to serve your application off of their servers.
If you just start an application on your personal system, you will suffer a lack of network and resource availability as well as under use of computer time at non-peak hours as your system will need to remain attentive for additional users without having alternative tasks. Hosting providers provide resources as needed, and their diverse client base allows their systems to work around the clock on a global scale.

Playframework : Deploy website

So, I have completed developing a website using Play 2.2 framework. I have a basic question of How to deploy the play application? I have followed the steps given in Play Production mode and generated files in target/universal/stage/bin and all related files using [project]$ dist command. Now, What I have to do with the files that are generated ? How can I put this live? Please specify steps require to deploy this application or a helpful article.
I am a newbie so this question may be too simple to ask.
Thanks :)
That's easy:
send the unziped files to server
find start and make it executable : chmod +x start
start the application on port 80 like ./start -Dhttp.port=80 (don't forget to use nohup, otherwise application will terminate, when you'll close SSH session)
That's all
Tip for easier maintenance you can use for an instance Jenkins - or some other CI system - with rsync command you can prepare one-click task for redeploying app even at distant location.
If you need to run more than 1 application at port 80 on the same machine use some lightweight HTTP server for reverse proxy and/or load balancing, i.e. nginx works perfect.

How to use a virtual machine with automated tests?

I am attempting to setup automated tests for our applications using a virtual machine environment.
What I would like to have is something like the following scenario:
Build server is automatically triggered to start an automated test for the application
A "build" script is then run which consist of:
Copy application files and a test script to a location accessible by the VM
Start the VM
In the VM, a special application looks in the shared folder and start the test script
The tests script do its job, results are output to shared folder
Test script ends
The special application then delete the test script
The special application somehow have the VM manager close the VM and revert to the previous snapshot
When the VM has exited, process the result and send to build server.
I am using TeamCity if that matters.
For virtual machines, we use VirtualBox but we are open to any other if needed.
Is there any applications/suite that would manage this scenario?
If there are none then I would then code it myself, should be easy but the only part I am not sure is the handling of the virtual machine.
What I need to be able to do is to have the VM close itself after the test and revert to a previous snapshot since I want it to be in a known state for the next test.
Any pointers?
I have a similar setup running and I chose to use Vagrant as its the same thing our developers where using for normalizing the development environment.
The initial state of the virtualmachine was scripted using puppet, but we didn't run the deployment scripts from scratch on each test, only once a day.
You could use puppet/chef for everything, but for all other operations on the VM, we would use Fabric scripts, as they were used for the real deployment too, and somehow fitted how we worked better. In sum the script would look something like the following:
vagrant up # fire up the vm, and run the puppet provisioning tool
fab vm run_test # run tests on vm
fab local process_result # process results on local shared folder
vagrant destroy # destroy the vm
The advantage is that your developers can also use vagrant to mimic your production environment without having to take care of that themselves (i.e. changes to your database settings get synced to all your developers vm's wherever they are) and the same scripts can be used in production too.
VirtualBox does have a COM API. I have no experience with it, but it may be possible to use that. One option would be to have TeamCity fire off a script to do this. I'd suggest starting with NAnt (supported natively by TeamCity) and possibly executing PowerShell if necessary.
Though I don't have any experience with either, I happen to have heard of a couple applications in this space recently:

Deploy ASP.Net website from SVN to multiple server?

I need to deploy a website from the SVN to different servers all within our own network. The code is currently not compiled but probably will be in the future.
First, the site would need to be deployed to the development server for the developers to test.
Once the Developer signs off, it would be deployed to the staging server for the testers.
Once final sign off was given it would be deployed to a server farm- two live servers.
Each server has a couple of settings in the web.config to that are different (except the two live servers, of course). I would like to use templates, the way the Ruby on Rails world does. It seems like an elegant solution to multiple web.config files.
I also need to create a list/report of the files that were changed and what the change was since the last deployment.
I am thinking of writing a script that will do the following:
1. Take args for server to deploy to, and revision
2. Export a copy of the source to a directory with svn export -r <deploy revision>
3. Delete the web.config file
4. Use ttree (a template tool http://template-toolkit.org/) to create the correct web.config
5. Create a list of file changes with svn list -r <deploy revision>:<current server revision>
6. Store the <current server revision> of the website for when the script is run next time
The problem I have is it doesn't seem like the most elegant solution. It could become unmaintainable, and I prefer to use tools that are already available rather than re-invent the wheel. Unfortunately I don't think MSDeploy will do what I need, but I'm happy to use it, or anything else, if it will do what I need it to. Does anyone know of any tools that are up to the task or is the script my only option?
Check out TeamCity. I have my build server setup so that it can deploy to different environments with different settings based on the build configuration all in "One Click". It's relatively painless to setup and integrates directly with Subversion and other source control systems. This would be a more elegant solution to the issue you are dealing with...

Does anybody create installers to deploy internal asp.net web applications?

I've always deployed my web applications via FTP (sometimes even xcopy), and then manually run database scripts myself.
I started deploying this way in the 90's, but lately, I've seen a few web apps with installers. I'm starting to question, if I'm locked into an out dated process. I'm a consultant, my apps are usually internal, so I don't worry about distributing and having others installing them.
But I'm curious; does anybody create installers to deploy internal asp.net web applications?
If so, why? (Voluntarily, mandated, or part of an automation process)
And have you had any problems doing it this way?
absolutely. We use it to do all of our apps. That way we create the installer and run it on the qa and uat environments to test and we know exactly what is going to happen in production. There are no guesses as to what order someone might do something in, or if they miss a step. It makes things a lot easier.
Ooh I forgot about the automated process too. We have systems in place (Ant Hill Pro) which automatically deploy it to the proper environments. The qa people don't have to wait for something to be done, because it's all done at 2 am. If they need to rerun the build with updates, the devs check the code in and we push a button, and it's automatically deployed. No waiting for the build engineer, because he's in a meeting or sick or whatever.
You always want to have an automated way to build and deploy - it greatly reduces the chances of a one-off error if you forget a certain step. Also, it allows you to offload the deploy to someone else easily without having to teach them 100 customized steps. Whether the project is internal or not, all applications should follow best practices.
Personally I'm a bit like the OP; generally I just deploy using FTP, but in saying that typically my applications are internal, or in the case of other projects, 100% managed by me.
I've also been thinking about this lately however, and have started to think about how using proper deployment may improve the process - having to document a detailed install process can be a real pain.
I use Powershell and found really easy to automate lots of tasks. You will probably find a bit different at the very begining but at the end you will see that it's all about the power of the .NET libraries !!!
I have use the "Web Setup Project" to create an MSI that installed the output of a "Web Deployment Project" for an internal app. Our server admin wasn't up to the task to doing a 50 step manual install. For my current app, my server admin doesn't like the 'black box' feel of MSI installers and prefers getting a pile of files and a 50 step deployment manual. (See a pattern here? Ask your server admin what he wants.)
The Web Setup Project doesn't make it immediately obvious how to install to anything other than the "Default Website", other than that, it made the installation process repeatable and created a built in way to rollback (by just running the installer from 1 version ago).
This of course assumes that your virtual directory doesn't hold any user modified content-- I wouldn't trust an MSI to properly merge user created and new files.
We use the "XCopy" deploy model here, since the Ops folks have their own method of setting up security on a new web application on the server.
However, we did need to use an installer when we had to install a web application that was using a newer version of Crystal Reports since it had to do something special with a key and we didn't have a full blown version of CR on the server itself. So keep that in mind when working with third party apps, they may need to do some kind of merge module that the MSI handles easily.
Yep...we have an app that needs a lot of pre-requisites set up....web service, windows service, user accounts, security, folder creation, GAC bits etc....I rolled it all up into a nice MSI with custom actions that can install and uninstall cleanly. Saved about one hours worth of work to deploy on a new box.
A lot of the other smaller apps are just deployed by doing Publish Website to a local folder then ftp'ing the contents to the target.
It greatly depends upon the scale of your project, your enviornment and your internal user base. I rarely deploy with an msi because we are too small an operation to have multiple environments (except for SharePoint, that's different all together) . We develop and use VS to deploy web apps to a development box, assuming they are approved then we use VS again to deploy to the live box.
The only proviso is that we have multiple copies of the web.config (appended with test, dev and live) and we then delete the suffix off the relevant file depending upon where its been deployed.
It's probably not the best methodology (I know it's not), but it works and it aids rapid deployment of small to medium sized solutions in a small-scale user environment.
F5ToDebug...
Your saying its OK to take short cuts if you dont have time to do it properly?
"who's going to test the code on the test environment?" You said it yourself that you have config files for _test - why would that not be a suitable test?
