What is the best process of dotnet deployment?
Starting from Code checkin to Jenkins and to AWS server.
FYI: We have multiple AWS servers which sync via DFS. So, currently we are deploying only to 1 server and DFS sync it to other servers.
Few questions:
Should we recycle app pool after every deployment? Is is necessary?
What about packages? Should we checkin with code or restore them at build server?
What about T4 templates? Currently, we checkin the auto-generated code as well because without installing visual studio at build server we can't auto-generate T4 templates.
After few months we will be using webpacks as well.
This deployment is used to regenerate existing 10,000 pages which has Output cache enabled. Also, these 10,000 pages are behind AWS CloudFront. This deployment and 10,000 pages share the same app-pool. What happens to Output cache after deployment? Should we have a separate app-pool and why?
FYI:
This deployment is only used for internal staff majorly. So, not much traffic to it.

In my organization the main product is a web application and an associated database. Both the web application and database is source controlled in TFS. We are running this product in various versions across hundres of IIS web site instances. When having that many web site instances on IIS deployment is atm. a problem.
What I want to do is to package my web application together with the output from my database project. I've been looking into creating a Web Deploy Package which makes it easy to deploy a web application remotely, locally or programitically to IIS if i want to.
What I want to achieve is to have one package but I want to know if it's possible to embed a Database project into a Web Deploy Package taking advantages of dacpac incremental database deployment?
If this is not possible is there any good alternatives to Web Deploy Package that suit my needs?
Another method is to create an MSI package to deploy both the Web Deploy Package and also update the DBs. For example, with Advanced Installer you can use the built-in support for Web Deploy Packages.
To perform dacpac incremental database deployment you can call SqlPackage.exe from the same MSI, as a custom action. The linked example shows a simple EXE running, but you can change that to run any desired EXE, passing your required command line parameters.
If you perform frequent upgrades of the websites, or the settings are usually changed after the installation/deployment, then you should take a look at the next thread too, it talks about persisting website installations during upgrades.
I am stuck with a problem that I could use some feedback on to solve it in the best possible way.
The issue revolves around source control -> automated builds -> deployment. Basically ALM (Application Lifecycle Management).
We have a product – an ASP.NET Web application with a MS SQL database. This product is running on hundreds of websites with associated databases across multiple virtual machines in our production environment. At the moment the web applications and database are running on servers with IIS 7 and SQL Database Server 2008 R2. The product itself is source controlled in Team Foundation 2012.
For years the release of new versions of the product has been once or twice a year for years. Now we are going to focus on releasing more frequently and hence we need a strategy for the ALM for the product.
The deployment strategy now:
In the development period between the releases, the SQL update scripts has been created manually – each time a database change was made a script was updated. When the application is ready to be deployed it gets compiled on a developer machine. The database with all the changes used would be backed up into a .BAK file. The web application, the .BAK file and the update SQL script would be packaged (.zip) and uploaded to the production environment ready for deployment.
Update existing running products:
Copy/paste the web application in the target website physical folder.
Update the web.config file – connectionstring and application
variables. Run the update script via SQL Management Studio
This would be done for each and every customer – hundreds of times.
This is a very tedious and error prone task and I don’t like it at all!
What I would like to do instead is;
Source control the database as a Database Project in Team Foundation
Automatically build the web application with Team Foundation 2012
Build Server.
Deploy the output from the Build Server to the multiple websites of
the production environment along with automatically generated SQL
update scripts run against the SQL Server.
I have been googling my ass off - only finding bits and pieces regarding builds, deployment, automatic SQL update script etc.
What I think is partly the right direction is to source control the database and use the TFS Build Server. I am very confused on how to do the deployment itself in an easy and controlled way using the output from the TFS Build server.
Ideally I would want to the TFS Build server to create a package with the latest version of the Web application, the latest version of the database, post deployment script including an auto generated SQL Update script from the previous build to the current build. This could be contained in e.g. a nuget package. Then I would want to be able to create an additional web application which should manage the deployment – target, version, iis website, sql server, web.config connectionstrings etc.
Does anyone have any advice on how to achieve this? How do you do this?
You can use a release management tool to do this, no need to create an additional web application.
One such example is Deployment Manager, from Red Gate. (Disclaimer: I work there.) It has built-in deployment actions for ASP.NET apps and SQL Server databases. The command line tool RgPublish.exe can be used to create a package for the web app as you describe from TFS Build. The same can be done for the database using the sqlCI.exe command line and associated NANT/MSBuild scripts.
The same packages can then be deployed to each of your servers. You may run into scalability issues with 100s of websites though.
The database deployment works by generating the upgrade script automatically, though you can change the behaviour to put the upgrade script in the package, when the package is first built. These are called "dynamic" and "static" upgrade methods respectively.
Does Microsoft offer a tool where you can deploy a web application to multiple web servers in a load-balanced environment/web farm?
My team is looking for a tool, preferably from Microsoft, where we can deploy our web application from development environment to production environment automatically.
If I understanding what your asking for your looking for a build server, to my knowledge Microsoft don't offer one, but some to take a look at are Team City, Hudson(requires a plug-in), and CruiseControl.net.
Basically they work by pulling from your source control building your application and running your tests. They all support scripting that will allow you to build then deploy to your servers. This can be set up to run nightly, weekly, etc. you can also set it up to monitor your source control for changes and build anytime it sees a change
The only one I've used is Team City, the install was easy, and depending on how many build agents you need it's free.
If your just looking to build and deploy from VS Another option is creating an NAnt script and running it from VS as an external tool.
For a good over view of Build servers check out this SOF question cruisecontrol.net vs teamcity for continuous integration
The Web Deployment Team blog at Microsoft has some reasonably useful information, and have a deployment tool you could try...
In the last environment we setup we used TeamCity for all our builds and deployments (Which is basically to say we wrote MSBuild scripts and automated them with TeamCity). In short we had the following 5 build configurations:
Continuous Build - Automatically rebuilt our product upon every check-in. Running all the tests. This build did not deploy anywhere
Nightly Build (Dev) - Automatically build and deployed our product to the development web server (no server farm). We build would run the tests, update the development database, shutdown the Dev IIS web site, copy the necessary files to our web server, and restart the site
Test Build - Like our Nightly build only it deployed to our test environment and it wasn't scheduled so it had to be manually started by logging into Team City and pressing a button
Stage Build - Like test only deployed to a web server that was externally visible to our customers sot that they could validate the application. Also, only run on demand.
Production - Created a zip file of our product that the deployment team could install on our production web servers
So I guess what I'm suggesting is that you use TeamCity and then write build scripts in such a way that they'll deploy to your Web Farm. If you want examples I could supply you with the pertinent portions of our build scripts
** One more thing: we check in our web.config files and such for each environment into subversion and then part of the build process is to copy and rename the appropriate config file for the environment. For example, web.prod.config => web.config in our production build
I believe that Sharepoint does this.
File Replication Service ( e.g. DFS Replication ) is a typical and very good choice for doing this.
Your changes are synced between member servers at the file system level.
Sharepoint does this automatically when you deploy a solution package.
Does anyone know any good solutions for automated deployment to a remote server using SFTP? I am specifically trying to deploy an asp.net mvc website to mosso. I can do it manually every time using an SFTP client, but would much rather have an automated (and consistent) way to do this.
I have written a pretty detailed blog post using TeamCity, and Web Deployment projects to automate build and deployment as a starter here:
http://www.diaryofaninja.com/blog/2010/05/09/automated-site-deployments-with-teamcity-deployment-projects-amp-svn
I have then added to this to show FTP addition
http://www.diaryofaninja.com/blog/2010/09/21/continuous-integration-tip-1-ndash-ftp-deployment
A basic process flow is pretty simple:
Using a teamcity build server i download from my SVN repo
I build and deploy the site to a local folder on the build server
I fire a command line FTP client that supports scripting called
WinSCP using the MSBUILD Task EXEC (http://winscp.net/)
Upload all my sites content
Have [insert beverage] of choice
I then make sure that i only deploy the Trunk of my SVN repo, and develop and test everything in an branch before merging - this way only tested stuff gets deployed. Add Automated testing to your build cycle and you've got a match made in heaven.
Some great free tools to get going are:
Visual Studio Web Deployment Project
TeamCity (free for under 20 build configs)
Bamboo
deployment tools under .NET solutions
Automatic Deployment Resources
We currently deploy web applications by creating a database and running SQL scripts through query analyzer. Then we copy the output from "publish website" and set up that website in IIS.
We have seen websetup in visual studio, but that part seems to be thinly documented. For example, we are not clear how to ask the user for IP and password of SQL server. We also tend to get websites deployed this way coming up under folders like http://example.com/project, instead of just http://example.com.
Then there are issues with AJAX.Net not being installed or some or the other patch not applied.
So far, we have physical access to the servers. Pretty soon though we are going to be shipping CDROMs. What is the practical tradeoff between manual intervention and automation?
Avoid Visual Studio deployment, and automate as much as possible. Web Deployment Projects and NAnt can be your friends!
Briefly, our deployment setup:
We use RedGate SQL to script differences between dev and live database.
An NAnt build file which calls MSBUILD to build the web deployment project (.wdproj), zips up the resulting compiled web app (along with the SQL change script) and then uploads the zip file to the server.
On the server side, there is another NAnt build file which takes the application offline, backs up the database, backs up the website. runs the SQL change script, unzips the new version and brings the app online.
Step 3 is usually run "manually" (one double-click), but sometimes scheduled for late at night. You could do exactly the same from a CDROM, or even write a pretty little Windows Forms app as a wrapper.
Quite happy to give details of the NAnt script if you're interested.
Have you tried using Web Deployment project? There is support for VS 2008 also now..
I deploy mostly ASP.NET apps to Linux servers. Here is my standard workflow:
I use a source code repository (like Subversion)
On the server, I have a bash script that does the following:
Checks out the latest code
Does a build (creates the DLLs)
Filters the files down to the essentials (removes code files for example)
Backs up the database
Deploys the files to the web server in a directory named with the current date
Updates the database if a new schema is included in the deployment
Makes the new installation the default one so it will be served with the next hit
Checkout is done with the command-line version of Subversion and building is done with xbuild (msbuild work-alike from the Mono project). Most of the magic is done in ReleaseIt.
On my dev server I essentially have continuous integration but on the production side I actually SSH into the server and initiate the deployment manually by running the script. My script is cleverly called 'deploy' so that is what I type at the bash prompt. I am very creative. Not.
In production, I have to type 'deploy' twice: once to check-out, build, and deploy to a dated directory and once to make that directory the default instance. Since the directories are dated, I can revert to any previous deployment simply by typing 'deploy' from within the relevant directory.
Initial deployment takes a couple of minutes and reversion to a prior version takes a few seconds.
It has been a nice solution for me and relies only on the three command-line utilities (svn, xbuild, and releaseit), the DB client, SSH, and Bash.
I really need to update the copy of ReleaseIt on CodePlex sometime:
