I have a scenario where I have to setup a test environment where I want to be able to tell my NAnt or other build tool to make an new IIS web application, put the latest bins in the newly created IIS web application, and post me an email where the new address and port where the new application are addressed, is this possible and how? which tool?
There are several ways to approach this:
Set up a continuous integration (CI) server on the test environment. This is a viable option if your test environment machine doesn't change often and it's a single machine.
Push the installation from your development machine using tools like PsExec
Combination of the two: you have a build CI server which pushes the installation to (multiple) test environments.
Of course, you also need a good build script which will set up the IIS application (NAnt offers tasks for this). Emailing to you can be done by CI server (CruiseControl.NET Email Publisher, Hudson...).
I suggest taking some time to read this excellent article series: Automation for the people: Deployment-automation patterns
Our CruiseControl .Net build server does exactly this as part of it's NAnt build-script process...
Once the code is retrieved from source control, it's all built/compiled in turn. Web projects are then handled slightly differently to normal .dlls, as they are deployed to a particular folder (either on the current machine or otherwise) where IIS (also set-up by the script) to serve the pages.
Admittedly, we're using Virtual Directories instead of creating and disposing of new website instances on the server, as otherwise we'd have to manage the port numbers for each website.
NAnt has the capabilities of doing all of this IIS work, as well as all of the email work too - I'd certainly recommend looking at this avenue of enquiry to solve your problem. Plus, you also get the continous integration aspect as a side-benefit in your case!

I am building a client-server application, this is all running locally on my computer whilst I am developing the system. However, eventually I would like to deploy the server-side part of the application to a server to run 24/7, enabling client applications to connect and consume the service at will. What I would like to know is, when I come to doing this would I simply just install the server-side application on the server, hit run and that's it? That just seems... well not right (to me), is this the way it is done? or is there a lot more to it? I imagine there is, but I can't seem to find any content on this subject.
FYI - the server is a self hosted WCF application.
You'd want to take your program's executable, support dlls and config files and drop them into a folder. Then create a Windows Service to run the program; if you don't use a Windows Service, the program will only run while you're logged on, which isn't good. As a Windows Service, a reboot of the server will bring the program back online even if you're not logged on.
Here's a knowledge base article from MS on how to make a windows service.
http://support.microsoft.com/kb/251192
If you're program is compiled as a DLL, then create a small .exe program to run it (a wrapper) then deploy the program as described in the article.
Good luck.
hey everyone.
ok, a little background to the project... I've released a program to a couple clients that use a WCF service for them to connect to our servers in the office. Being that i used the clickOnce setup utility in VS2010, when i am doing testing on a VM i publish to a different spot on the server as to not give untested code to clients. However, the WCF service only gets published to one place for both versions (development and release).
What i'm working on now requires a change to the WCF service as a couple additional things get transferred between client and server. If I publish the modified WCF, will it affect the current clients, or will i be able to test my development version with no worries? I'm afraid i already know that the answer will be, yes it will affect them.
thanks!

Isolation of test, dev and production:
Whenever you need to test something or put it in production, you need a separate environment. So you need a separate machine to develop and do local testing, another to test the checked-in code (for use by a tester, a customer etc.), and another to run the production code -- at the very least.
If your service interacts with other software, especially with software that gets updated a lot, this is an important way to make sure that you don't introduce side-effects and that what you build will be compatible with what is running on your production server.
So: isolate and make your test environment a "clone" of your production environment.
Two versions in parallel:
If you update your own code for customer X, you can still host a previous version of your production code for customer Y on another (virtual?) server. Customer Y can then choose when to switch to your new version, after which you can take the old code out of production.
You should create a seperate VM for your test environment.
I'm currently setting up a new build server and I'm interested in any suggestions the community may have about software such as Hudson or CruiseControl.NET that may simplify and add additional value to the build process.
Previously I had a build server set up using custom batch files which would run msbuild and other such tools and these were triggered by subversion hooks to allow for a continuous builds to be done per branch. The idea was that eventually we would also execute automated tests and/or static analysis although we never really got that far. This server also acted as our source code repository, a test machine for web project builds, and a web server for custom dashboard and portal for developers on the team.
At this point my thoughts are to separate some of the responsibilities of the old build server and at least a Build Server which is responsible only for creating builds, a web server which is responsible for acting as the intranet style dashboard site for developers, and perhaps an additional web server as the Subversion repository. If it turns out to be better or easier to keep the Subversion code on the same server as SvnServe then I'll probably opt to place the Subversion repository on the web server but still keep the build server separate. Having no personal experience with any of the popular build server and CI solutions out there I'm curious how CruiseControl.NET, Hudson or other solutions would fit into this type of configuration. It appears that both of CC.NET and Hudson have web interfaces for example but the documentation doesn't clearly layout how this plays out with different hardware/system configurations so I'm not sure if either requires the web portion to be on the build server itself or not.
As far as technologies I'm dealing with .NET/C# based code which is a mix of Web/WinForms/WPF and we use a few separate Subversion repositories to host these projects. Additionally it would be nice to support Visual FoxPro and Visual Source Safe for some legacy applications. I would also like to get more team members involved in monitoring builds and would like to eventual have developers create build setups for their own projects as well with as much simplicity as possible. Also I should mention that I have no experience setting up a Java based web application in IIS but I do have quite a bit of experience setting up and managing ASP.NET applications so if that may make .NET based products more favorable unless I can be convinced otherwise.
UPDATE (after researching Hudson): After all the recommendations for Hudson I started looking into what is involved to get it up and running on my two Windows 2008 servers. From what I can gather the web portion (master) would run on my webserver but it seems that IIS isn't supported so this would greatly complicate things since I want to host it on the same machine as my other web applications. On the build server, I would be installing a second copy of Hudson that would act as a slave and only perform builds that are delegated to it by the master. To get this to work I would be installing Hudson as a Windows Service and would also need to install some unix compatibility utilities. Unfortunately the UnxUtils download link appears to be broken when I checked as well so I can't really move forward until I get that resolved. All of this is really sounding just as complex if not more complex than installing CruseControl.NET. For now this unfortunately leaves me to looking into CruiseControl.NET and TeamCity.
UPDATE (about TeamCity): After looking into TeamCity a little closer I realized that at least the server portion is also written in Java and is deployed in a manner very similar to Hudson. Fortunately it appears that Tomcat can be used to host servlets inside IIS although I can't find a good straight forward guide to describe how to actually do accomplish this. So skipping that for now I looked further when I ran into what looks like what might be a major snag.
TeamCity Professional edition only
supports TeamCity Default
Authentication and does not support
changing the authentication scheme.
Since windows authentication is likely the direction we will want to go, it's now looking like it might be back to evaluating CruiseControl.NET or possibly Hudson if I can get my hands on the UnxUtils and also find out more about how I can host the dashboard portion of Hudson within my existing IIS configuration. Any pointers?
UPDATE (about Jenkins): I ended up experimenting enough with Hudson that I ended up with a reasonable build server setup that I'm happy with and that can be extended to do much more if I need. Of course I went the rout of converting to Jenkins once Oracle took over Hudson and Jenkins is what I'm using today with little bits of powershell to help tie things together. I'm very happy with this approach right now and besides being Java based, Jenkins has quite a bit of support for other development environments such as .NET and MSBuild.
I'd vote for TeamCity here. Its is very, very easy to get stood up and running, integrates with all your .NET stuff without any trouble. The builds themselves are run by agents which can be on the build server or another machine depending on requirements--they could even be on a machine running an entirely different OS on a different network in a different country.
I highly recommend using Hudson. Not only will it allow you to build .NET applications on a continual basis, but you can also run code analysis and unit tests as well. It's easy to install (just deploy a WAR file to a web server such as Tomcat) and has many configuration options. There is also a large number of plugins available that you can use, many written by other Hudson users. Best of all, it is free and actively supported.
For our decision making process we started with following overview.
http://confluence.public.thoughtworks.org/display/CC/CI+Feature+Matrix
Our main objective was java, easy to configure/use even after nobody created a job for 6 months. We moved away from a old version of Cruise Control, since nobody really knew how to use it. Some of the commercial products are nice if you want to go beyond just continuous integration. Have a look and decide for yourself.
Be careful, I don't know how up to date this matrix is. So some of the projects might have implemented more functions right now.
An interesting alternative could be Jira studio by Atlasian. If you use the hosted version you don't have much on support issues and it comes with subversion, bamboo, and goodies (jira+greenhopper, confluence, crucible, fisheye). http://www.atlassian.com/hosted/studio/
I agree with Wyatt Barnett. TeamCity is the best choice. It is very easy to configure and use. Moreover, TeamCity has a Free Professional Edition. Previously we used CruiseControl.NET on our project. This is also a powerful tool, but it is very complicated and hard to understand.
What s.ermakovich said: Both TeamCity and Hudson separate the web UI from build agents. You shouldn't need to install IIS on a build agent. You'd need to install a JVM and the agent software on any build node - very straightforward.
I'm in the process of providing a Web UI as an alternative to our current desktop UI for our C/S enterprise application.
When developing the client-side in our desktop version, UI developers could connect to any server so they only needed the client-side environment.
When developing a Web UI (Client-side JavaScript in the browser), we are bound by the browser's "Same origin policy" so the UI must talk to the same server from which the UI code is downloaded.
As far as I see it till now, the development scenario for the UI guys is:
Developer installs server on local
machine and runs it.
Developer edits the HTML+JS+CSS files on local installation.
Developer has to reinstall/update server on local machine each time there's a need to test UI code against new server behaviour.
This does not seem too comfortable, at least compared to our previous C/S style development.
Are there any other ways you can suggest to that will not require UI developers from installing and updating server side components on their development machine ?
Or anything else related that can simplify the development process ?
Thanks :-)
Editing in some clarifications:
I'm mostly interested in the aspects of UI coding, not UI design.
I need a lot of server interaction - getting data from RESTful web services, which are developed in parrallel - hence the need to have an up-to-date server
You haven't specified the development platform.
As far as pure HTML/JS/CSS is concerned, you don't need a server. The UI developer can fine tune UI components locally.
The moment you want to talk/integrate to Server (via AJAX, JSP, ASP...) then you need to connect a development server as now your changes have to be served by Server.
Most of UI fine tuning can also be done from Firebug
In our office when changes to styling are required we save the page as a local copy and send it to the UI designer, he makes his changes and we integrate them. So the UI designer don't have to maintain a development environment.
JSONP lets you work around the same-origin problem (with server support) -- check it out! If the front-end-in-the-browser developers are using a good framework suc as jQuery or (my favorite) Dojo, JSONP should be no harder for them than plain JSON.
Develop on a shared server, but depending on the size of the team.. that's challeging with respect to version control.
Or deploy automatically generated virtual machines with nightly builds, so the devs don't have to install, but always use a recent version.
In the case of UI developers depending on a common REST server, the UI development can be done on the local machine and the REST service should be on a central server. When changes are made to the REST service these should be deployed to the central server (when stable), so all developers can use the newest version (this also helps with testdata).
You could try using a proxy on the developer's machine where some paths redirect to the server and some paths redirect to local folders.
Hmm, I actually didn't really get any information on what kind of technology you're using. If - with UI Developers - you mean designers, which have to take care about the CSS, layout etc, then we do it the same as lud0h said. We (developers) send the UI designers a copy of the server-side produced HTML pages. They then edit the HTML pages according to accessibility guidelines, CSS and layout and send us back the outcome of their work. We use their HTML pages then for integrating them in our web applications.
If you don't just mean tuning CSS, but also to write JavaScript / Ajax functionality you HAVE to use a server with which you're communicating. As you said, normally this is done by having a local environment which is similar to the server-one. In .Net Visual Studio '08 provides an internal webserver, alternatively you have to install IIS locally. In Java environments you have to install Tomcat and related technologies. In my eyes this is a must. What you have to have is
Versioning system (CVS, SVN,...) where developers commit regularly (minutes/hours)
local environments where developers checkout the source from the repository and develop
Test server where you deploy on a daily basis (could be like daily builds) in order to test your running product
I guess this should be what a professional development environment should consist of. The difference to C/S application development is that web UI and web-client code are not that separable as a Client UI in C/S environment from the server-side. Unless you develop with technologies like GWT or Silverlight which are quite similar to C/S, just running inside the browser, but communicating over RPC calls or web services.
//Edit:
What I nearly forgot. Don't do something like developing on the server directly, meaning that all of the developers access the server's filesystem where the code, UI etc. lies!!
You can use CORS. a new technique just like Ajax, but with ability to make calls on other domains. so you will need only one UI on one server. think this can help you.
I am in the process of setting up some IIS hosted WCF projects for continuous integration and am stuck trying to find the best and simplest way to get deployment automated.
Right now, I have the build and deploy working with CC.NET, MSBUILD and a batch file that copies the necessary files to the deployment folder, but I think there must be a better way.
Ideally, I'd like something like web deployment projects, but for WCF.
I would settle for a nice Power Shell script to copy all the necessary files and exclude all the fluff.
Well, there isn't anything stopping you from using a web deployment project for hosting your WCF class library. The SVC file will be picked up by IIS and routed appropriately. We use a standard deployment project and a custom action to create the IIS vroot so that we have a finer control over the settings but a standard web deployment project will do the job as well.
Unless you are running under IIS7 then as far as IIS is concerned it's just standard content that has it's own handler. When you get to Windows 2008 / Windows 7 Beta then things can change a bit as those versions have a very different handler model.
I've found this post to be really helpful: http://msdn.microsoft.com/en-us/library/bb332338.aspx
This depends very much on the technologies you are using. On a previous project, we used TFS, with Team Build. The result was that the WCF projects were built into a folder structure that matched their deployment structure. Additional tasks in the MSBUILD script triggered a deployment script (written in PERL, I think). This took care of all deployment tasks, from deleting old folders, creating the new, creating databases and populating with reference data, then deploying the service and web sites, and finally running Installation Verification scripts and publishing the results to a web site.
On the other hand, if all you've got is a hammer, then hammer away.
