Way ahead in learning octopus Deployment - deployment

I am totally new to Octopus Deployment and I am struggling to find a starting point
What is the best pathway to take to understand the basic fundamentals of octopus deployment ?
Are there any pre-requisites ?
Amy recommended courses/books that I can take ?

I was in the same situation as yourself. I had zero training and was thrown in at the deep end.
I would suggest you start with a simple application and get your head around the 'process' steps required to deploy your application. For example, A simple site may have the following steps:
Stop the app pool and site in IIS
Deploy the site to IIS
Execute any SQL scripts
Start the app pool and site in IIS
There are a number of built-in steps that can help with this. I suggest you have a look through them.
You then want to look at the 'variables' required for each environment. Again, for example, you may have a variable for the website hostname with values such as:
DEV = website-dev
UAT = website-uat
QA = website-qa
LIVE - website-live
When deploying the app to different enivorments, a different set of variables will be used.
Have a look at the Octopus youtube page for some good resources:

I found Octopus easy to pick up simply by trial and error.
Good luck!

How do we control application type versions retention?

We want to execute external integration tests and manually call a rollback if something is wrong.
We're using the 'Service Fabric Application Deployment' task in Team Services (VSTS) and it seems to only keep the latest in the cluster.
Cluster --> Applications --> [Application], and then under Essentials. Only one row item is listed which shows the latest version.
Also, attempting Start-ServiceFabricApplicationUpgrade results in 'Application type and version not found.'
How do we alter the behaviour of previous version retention of application types? (And what is the default?)
I don't have the answer to your question, but I do offer this thought:
While I understand there may be a valid use case out there for trying to do this, I think a more accepted approach is to set up a test environment that matches production very closely. Deploy to test and test the heck out of it before approving the deployment to production.
One of the main selling points of Service Fabric is its ability to be so redundant, yet with your proposed workflow you are deploying code to that environment in which you're not entirely confident in. I think that really goes against what Service Fabric offers you.
Since you will be testing it so thoroughly on the Test environment, hopefully anything you end up finding in Production is small enough to be fixed through a patch a few hours later or however fast you can fix it.

Automated deployment of web site

I'm planning to do an automated deployment of a website,but im kind of stuck at this moment. I have looked at MS-Deploy, it got all the functions for deploying Website. I have a created a Web application package (.ZIP file) and I tested this on my local machine it is deploying website i.e
Create Web application under default website
Publishing files in c:\inetpub\wwwroot directory
Set ACLs on directories,etc
But i want to achieve few more extra steps for example:
Check whether Web application exists in Default Website, if not
create a Web application
Check whether Application pool exists, if not create a App pool
(given name) with a specific credentials and Assign App-pool to Web
application
Before it deploys take a backup copy of existing Web application (IF
exists)
publish offline page (app_offline.htm)
publishing the files to application directory
Replace the AppSettings section(in web.config file) to with actual values
Encrypt Web.config connection string
If there is any error whilst installing web application, rollback the web application to its previous version
The question is whether can i achieve all these functions via MS-Deploy or do i need to write any script, please suggest me what scripting language should i use
Please let me know if you need more information.
Thanks in advance
I'm not an expert on this topic but have been doing a bit of research on automated deployment with MSDeploy lately, and think I can offer the following;
This is default behaviour if you use the iisApp provider.
I know you can do this with the appPoolConfig provider, but I'm unsure as to how you would run this and #1 together as part of the same package. Perhaps as part of a pre- or post-sync command?
This is standard in v3, as long as it's set up on the server. Not used it myself, but read this anyway.
Fiddly. Not supported in MSDeploy, but you can vote for it if you want. Also, check out this SO answer (and also worth checking out PackageWeb, but the same answers' author).
Not sure I follow. This is done as part of a successful deployment, surely?
Use web.config transforms and optionally the aforementioned PackageWeb for a neat way to do this. Also check out Web Publish Profiles.
Difficult. My understanding is that the encryption is based on the machine.config, so you'd either have to run a post-sync script which would run some sort of remote Powershell script on the remote server to encrypt the web.config using aspnet_regiis, or you'd have to encrypt the config as part of your build process and then muck about with custom keys and the RSA provider (some info here).
I hope that helps. As I said, I'm no expert, so happy to be corrected by those more knowledgeable. Maybe also worth mentioning that MSDeploy is a lot more powerful if you use it via the command-line rather than creating packages from VS, although there is a bit of a learning curve to go with it.

how can I set up a continuous deployment with TFSBuild for MVC app?

I have some questions around the best mechanism to deploy MVC web applications to different environments. Previously I used setup projects (.msi's) but as these have been discontinued in VS2012 I am looking to move to an alternative.
Let me explain my current setup. I currently have a CI setup using TFSBuild 2010 with Team Foundation Server for source control.
A number of developers work on their local machines and check in to the TFS Server. We regularly deploy to a single server dev environment and a load balanced qa environment with 2 servers. Our current process includes installing an msi which carries out some of the following custom actions:
brings current app offline with the app_offline.htm file
run in database scripts (from database project in the solution)
modifies web.config (different for each web server of qa)
labels the code
warmup each deployed file via http request
etc
This is the current process. Now I would like to make some changes. Firstly, I need alternative to msi's. From som research I believe that web deploy via IIS and using MsDeploy is the best alternative. I can use web config transforms for web config modifications. Is this correct and if so, could I get an outline of what I need to do?
Secondly I want to set up continuous delivery via TFSBuild, I have no idea how this may be achieved, would it be possible to get an outline of how it can be integrated in to my current setup? Rather than check in driven, I would like it to be user driven following check in. Also, would it be possible for this to also run in database scripts from a database project in the solution.
Finally, there is also a production environment, but I would like to manually deploy this - can my process also produce an artifact that I can manually install?
Vishal Joshi has some information on his blog that is reasonably good, http://vishaljoshi.blogspot.com/2010/11/team-build-web-deployment-web-deploy-vs.html. It does have the downside that your deployment password is include in the properties you pass to msbuild.
Syed Hashimi has also posted some information on this in another questions Team Build: Publish locally using MSDeploy.

What is the best way to automate windows azure deployment?

Newbie to automated azure deployment here! I have the happy task of automating our deployment to the cloud. I have also done some reading and discovered that the 2 main tools are MSbuild and Powershell. Please could anyone tell me why i would use one over the other or indeed if there are any better ways to automate the deployment. Keeping in mind that my main concern is performance and i need this deplymrnt to be as fast as possible.
Any insight would be most welcome.
I'm a fan of using PowerShell for deployments. It's pretty quick to set up and the script can be pretty straight forward.
MSBuild can be great too. I use MSBuild from TFS Team Build to kick off a PowerShell script to do the deployment. Works like a champ.
A good starting point would be http://blogs.msdn.com/b/tomholl/archive/2011/12/06/automated-build-and-deployment-with-windows-azure-sdk-1-6.aspx. This blog does a great job of showing you how to build and deploy with Team Build.
If you don't want/need the Team Build and MSBuild part, then just look at his PowerShell script. That covers the basics of getting a deployment from your dev environment to Windows Azure.
You should use Web Deploy, it only takes about a minute to deploy a fix. See these links

At SplendidCRM, we had a similar need to automate deployments to Azure, but as our need was to service our live customers, we had to develop using C#. We have been watching Azure for many years, but it was not until they provided a DNS service did it make sense to make the move. Using the Azure Resource Manager (ARM) libraries, we were able to automate VM creation, SQL database creation and DNS name creation. In addition to the Microsoft documentation for ARM, we found it particularly useful to be able to get the Microsoft source code for the PowerShell scripts that wrap ARM. This is because the documentation does not always provide a complete set of settings.
In the end, we decided to release the Azure deployment code as part of a new Ultimate edition that combines order and customer management with software deployment.

How Do I deploy an application to IIS while that web application is running

Where I work, we release bug fixes in to the system every night when we know our clients are not using the system.
Trying to take a step towards better service I'd like to deploy to IIS while the application is running.
A solution that comes to mind is to setup two different IIS applications and switch them over after deploy using a script. But I'm not going to try this out as I don't want any complications during our busy hours.
Does anyone have experience in this area of deployment?
Thanks
Regardless of whether you're using PHP, ASP, ASP.NET etc there is no native support for transactional deployment on IIS.
The simplest approach would be to have two physical folders and (optionally two web sites - one production, one test) on your web server, for example:
c:\websites\myapp\dep1
c:\websites\myapp\dep2
Initially your site would have its physical path pointing to c:\websites\myapp\dep1.
When you deploy your latest build you'd deploy into c:\websites\myapp\dep2. Once you're done just switch the physical path of the production site over to this folder. This means you still have the original site and can fall back to it if the new code fails for whatever reason.
The next time you do a deployment you'd deploy into c:\websites\myapp\dep1 and once you're done switch the production site to that folder.
You could optionally have a test site that points to the folder you're deploying to so you can make sure the site works before switching your production site over.
This could all be scripted.
