Rule movement/promotion across environment (say UAT to Production environment) - drools

We are new to Drools rule engine. Can anyone guide us how the rule promotion is handled from one environment to another?
Say, in UAT environment, business users have created the rules and verified the same. If we want to move those rules to production environment then what is the suggested process for the same. We heard that the rules are stored in git repository from Drools work bench. Do we need to use that git repository to promote rules form one environment to other ? If yes, then what are the steps ? we need to move, selective rules from one environment to other. Or there ware options like export from one environment's workbench (uat environment) and import the rules in other workbench (production) environment? Any automation available?
Or selective rules can be directly compiled from one environment (UI and/or script) and deployed in the KIE rules execution server in another environment?
Any guidance is highly appreciated.
Thanks & Regards

Kubernetes Preview environments

I would like to ask what people use to provision an ephemeral preview environment in AWS EKS for your service under test. Also in addition, I am curious to know how you provision any dependent services (such as Database).
E.g. I am working on a back-end service and would like to deploy an isolated ephemeral version of this service packaged from my feature branch, including the database. Furthermore, I would also like copy of a front-end service in my isolated environment to test my back-end.
Any thoughts would be appreciated
Thanks

You can roll your own solution: by wiring together your own CI/CD (Jenkins, CircleCI, BuildKite, Github Actions, etc) solution to trigger building and deploying of a preview environment by tying in to webhooks on your source repository. This would have to include your building of the modified code, then deploying that code to some staging environments, then of course seeding those environments with some type of data.
There is a bit of nuance to getting this right. You should check out https://ephemeralenvironments.io/ which is a good template of what needs to go in to these environments.
A lot of other folks use services that provide this as a SaaS platform, Shipyard.build, Release, and Velocity.tech are a few of your options.

Hope this helps!

Sonar cloud new code only supports master/default branch

Currently, we have already implemented the SonarQube on Azure VM, Due to cost and maintenance activity, we are thinking about moving to SonarCloud. Basic differences we are having from the pricing point of view and LOC, by feature-wise, am looking for major differences
Question: We have observed that in SonarQube we can set new code analysis on any branch whereas I did not find the same thing in SonarCloud it only allows me to set new code only on the Master/Default branch, the rest of the branches are not having options to set, also If I set the previous version, specific analysis the build fails for other branches except for master/default.
How can we set a new code rule for branches?
For SonarCloud, the prime focus is on the developer’s workflow and bringing value to the development team within their existing ALM environment. Thus, the ‘Enterprise’ use-case is not currently addressed by SonarCloud.
SonarCloud is hosted by SonarSource in AWS and your code will be stored in a private subnet which is secured but again it's your choice..!! (We prefer to keep our code in our own infra)
For Enterprise use-cases, explore SonarQube
SonarQube Enterprise Edition (EE) includes a few management features that may be valuable to your organization. SonarQube along with a supported database is installed on your own on-site servers or in a self-managed cloud environment
SonarQube is enterprise ready application with all the required configurations whereas SonarCloud is missing enterprise level functions such as Authentication, Portfolios, Global settings, Branch & New code, and Housekeeping etc. that is why you are unable to set New code analysis on branch level.
SonarCloud meant for small projects that focuses on Master where your application will be built and deployed using only Master/release branch and rest of the branches are considered as a short-living branches in which we don't get much more options to play.
As part of Licensing and services both products cover essentially the same languages (SonarCloud doesn’t support PL/I, RPG or VB6) and support similar functions, SonarCloud additionally offers a SonarServer and Database to store the code and results with all the services like database and server SonarCloud still much more cheaper than the SonarQube but why? --

How to manage logical grouping of microservice based application to ensure version compatibility for CI/CD Pipeline?

For the MicroService Architecture based application, I'm trying to understand a standard process about how to logically group and manage correct version compatibility among independently deployable microservices. Let me elaborate with practical scenario :
Say, I am building a software application which is composed of 10 microservices. All the microservices have their independent repositories(branching workflow etc.) and their separate CI/CD Pipeline.
The CI/CD Pipeline gets triggered whenever any change pushed to 'master' branch for respective microservice.
Considering Helm chart and Kubernetes based deployment, all the microservices will get deployed with version 1.0 for the very first deployment and our system would work. For subsequent releases, we might have only couple of services that will get deploy. So after couple of production releases, each microservice will be at different version to constituent an application at that point of time.
My question is :
How to logically group independently deployable microservices in order to deploy or rollback to earlier release i.e. how to determine what was the version of different microservices for earlier releases?
Is there any existing tool or standard practice to track versions of each microservice for given release to seamlessly rollback to expected release?
If not automated solution, what would be the right approach to address such requirement?
Appreciate your thoughts and suggestion on this.
With consideration kuberenets:
1. Helm is nice tool to deploy and track.
2. Native k8s deployment works nice, you need to use deployment properly especially look --record flag in k8s commands eg check this link
With AWS ECS clusters:
1. they have task definations and tasks. I think that works for you.
Not have pointers for docker-compose, swarm, and other tools. But you can always use the power of git and some scripting.
the idea is make a file that lists all versions of services/containers/code . and commit that file in git with code. Make tag out of it for simplicity. your script should compare this state file and current state and apply specific changes only. Look at git submodules also. it is nothing but a group of many git projects and it tracks status of each project with help of commit id of each project. This helped us in the situation you mention.
This is a fairly new problem, we just launched a new tool Reliza Hub to solve that. Also here is my post on the subject: Microservices – Combinatorial Explosion of Versions. Currently, we are at the MVP stage and a lot of work is going on - see this video tutorial if our direction makes sense for you https://www.youtube.com/watch?v=yDlf5fMBGuI
If you decide to implement and have any questions or need help with integration, just tag me on SO and I'd be very much willing to make it work for you.
To sum up few things that we are doing - we denote developer facing projects (those that map to source code) as Projects and customer facing projects (bundles that customer sees) as Products.
And we say that Products are essentially composition of Projects and provide tooling how you can compile different versions of Projects into what's called a Product bundle. You can then integrate this into any CI or CD tool out there or start manually if you haven't configured CICD yet.
Other than that, yes - I highly recommend helm and kubernetes - this is what we use on newer projects. (And I can also add ArgoCD and Spinnaker to the existing tooling). But it is not enough to track permutations of different versions of microservices and establishing which configurations are good and which are not between different environments.

VSTS + Octopus Deploy? Why do I see a lot of CI/CD setups with both?

I'm a developer whose transitioning into Devops. By observation, I've noticed that a lot of dev shops have started using Octopus Deploy and Azure Devops Services (AzDo, formerly VSTS), or they are starting new projects to setup devops ci/cd pipelines AND they spec to use both tools.
I've been through some quick training for both tools and though they aren't perfectly the same, AzDo seems to offer all of the same features as Octopus Deploy.
So, my question is if a company is already using AzDo for much of their version control, or anything CI/CD pipeline-related, why would you use Octopus? What benefit does it offer to use Octopus for your build and deploys to AzDo?
Note, I am very, very new to Devops. I'm just asking because at the "10,000 feet view" there doesn't seem to be any reason for Octopus if you're already using AzDo. I mention Octopus Deploy by name because I see it come up frequently. However, I assume there could be other tools that serve the same purpose of automatic build and deploying that might also integrate with AzDo. However, AzDo offers build and deploy built in one. Why split out the work?
Let me preface why I like to both build and deploy with VSTS:
Same permissioning end to end
Line of sight from end to end build and deployment
Reasons I favor Octopus Deploy over VSTS Release:
Ability to upload packages/artifacts
External ones that are maybe one off packages to get deployed for a specific release
Target Definition
When you create Targets or servers you are deploying to, you are able to add a target to one or multiple environments and assign tags/roles to a target. What does this mean? More flexible server definition rather than defining strict Agents to a pool or servers to a Deployment Group, you can allow a target to span multiple (ie: a testing server that spans your Dev and Test environments and only gets triggered on steps that are defined for that role). I realize you can accomplish similar things to this in VSTS but in my opinion it's far more cumbersome.
Variable Definition
Variables can be grouped at a global level and grouped by a specific pipeline/process (that part is similar to VSTS). Variables can also be grouped or scoped by environments or roles (above) so you are able to have different variable values per role per environment; both super granular and flexible. Places this comes in handy is if you have a backend server with a connection string and maybe 2 content delivery nodes (role - content delivery) that get slightly different values than the backend server. At the moment, I do not know (other than creating new environments) how one would accomplish the same in VSTS.
Process Definition
All of the above comes together in the process definition of Octopus Deploy. The super flexible and granular variables and target definition allows you to focus on the actual deployment process rather than getting hung up on the nuances of the UI and its limitations. One example would be defining a process where the first step would be taking something out of a load balancer from a central server, step two deploy code to delivery server one, step three put back in lb, step 4 take out node two from lb called from a central server, step 5 deploy code to node two, and last step, back into load balancer. I realize it's a very simple hypothetical, but within Octopus Deploy, it's one steady process filtered to execute on specific roles, within VSTS you would have to break that down into different agent phases and probably pipelines.
Above are really the biggest points I see to use Octopus Deploy over VSTS Release. Now why would someone use VSTS to build and OD to release/deploy? There are a lot of different factors that go into it, some are corporate drivers like having an enterprise git client that has permissions handled thru MSDN. Sometimes it's a project management driver of having work items tied tightly to commit and builds, but with the added flexibility that OD brings to the table for free/minimal cost.
Hoping this help shine a little light into maybe why some people are crossing streams and using both VSTS and OD.
A lot of good points have been made already, but it really comes down to what you need. I would venture a lot of us started using Octopus before Release Management was really a thing.
We use VSTS for all our source control and builds and then all our deployments are handled through Octopus.
When we started evaluating tools, VSTS had nothing for deployments. Even now, they are still playing catch up to Octopus in feature set.
If you are doing true multi-tenanted and multi-environment deployments, I don't think VSTS really compares. We are using Octopus with around 30 tenants, some on Azure, some on premise. We deploy a mix of web and desktop apps. We are even using Octopus to deploy some legacy VB6 and winforms applications.
Multi-Tenancy (critical for us)
VSTS added Deployment Groups a while ago which sound pretty similar to Octopus Environments before multi-tenancy was implemented. Before Octopus had true multi-tenancy (it's been around a while now), people would work around it by creating different environments per tenant, like "CustomerA - Dev", "CustomerA - Prod", etc. Now you just have your Dev/Test/Prod environments and each tenant can have variables scoped to those individual environments.
Support
Documentation is excellent and it's really easy to get up and running.
The few times I've needed to contact someone at Octopus, they've answered very quickly and knowledgeably.
Usability
Having the Octopus dashboard giving us an overview of all our projects is amazing. I don't know of anyway to do this in VSTS, without going into each individual project.
Octopus works great on a mobile device for checking deployment status and even starting new deployments.
Community
Octopus works with their customers to understand what they want and they often release draft RFCs and have several times completely changed course based on customer feedback.
If we know what sort of applications you are deploying, and to what kinds of environments, we would be able to better tailor our responses.
The features you see today in VSTS weren't there a few years ago, so there might be an historical reason.
But I want to state here some non-opinionated reasons that may suggest an organization to opt for different tools instead of one.
Separate responsibility and access levels
Multiple CI tools in dev teams (orgs that are using also Jenkins or TeamCity or else) and need to standardize and control deployments
An org needs a feature available only in Octopus (maybe Multi-tenancy)
Octopus does a great job of focusing on deployments. Features reach octopus before vsts, support is local and responsive. That, and you never run out of build/release minutes!
Seriously though, I just like to support smaller companies where possible and if all features were equal, I'd still pick them.
The big reason in the past was that TFS On prem and early VSTS did NOT support non-Microsoft (.Net) code very well if at all. You could utilize the source control and work features of TFS and then use octopus/Jenkins etc... as the build release parts to cover code that TFS didn't really know what to do with.
Also the release pipelines used to be very simplistic and not that useful where the other products were all plugin based and could do (almost) anything you needed them to. Most of that has changed so that VSTS is much better at working with Non-Microsoft code bases then it used to be. Over time integrations get created inside a companies walls and undoing those decisions can be more painful then just having "too many" tools. Also I feel like there is just more people out there familiar with those tools since they have been mature longer and cover a larger part of the development world then VSTS has in the past.
To fully implement CD you need both. VSTS runs tests and is a build server. OD isn’t. VSTS is light on sophisticated application installations. And if you are provisioning environments, IaC style, you need Terraform in addition. Don’t try to shoehorn everything into a single tool. DevOps requires a whole ecosystem. The reasons are not historical.

Using VSTS Release Management, how can I modify the configuration of an Azure Web App for each environment?

I'm using Visual Studio Team Services and I'm trying to set up Release Management to allow automated deployments for our Azure Web App to multiple environments. I would like the same source to be deployed to each environment, but with modified configuration settings.
I was hoping that I could create a single Build for my application, and then modify the configuration at deployment time for each environment. I'm aware that this can be done for appSettings and connectionStrings (either through Tokenization, or even managing those settings via the Azure portal), but I'd like to be able to make more general changes to the web.config file. For example, I want to be able to:
Update 'simple' settings such as appSettings/connectionStrings
Update multiple attributes on elements (like httpErrors)
Insert or rewrite sections of the config file itself (for example to add IIS rewrite rules, or to remove unwanted HTTP handlers for production)
Currently we achieve this by using config file transformations and separate publish profiles for each environment (manual deployment). I can't see a way to re-use this if I want a single release pipeline.
I'm hoping someone can help point me in the right direction. I'm also happy to accept alternative solutions - ultimately I just want to be able to deploy the same source (e.g. from the same commit in source control) to multiple environments, with different configuration, while keeping some kind of flow from dev, to test, to eventually production.
You can use Tokenization Task to update the files base on the environment variables.
