we are planning to install directly from kubernetes.io, instead getting it through vendor, for example open shift, rancher, etc.
How should we go about support if we have problem with our kubernetes cluster?
Of course, vendors also gets their kubernetes source code from kubernetes.io and don't change it.
Thank you.
Using OSS software directly means that whenever you face a problem you need to solve it yourself.
Having said that, there is a very wide array of communities filled with friendly people who would probably be happy to lend a hand, at least that's what I've learned through my experience.
A few places you should try are the issues section of the kubernetes project, kubernetes slack workspace, r/kubernetes.

I have to say I am fairly new to CI/CD and how to automatically update softwares.
I am developping a monitoring software for industrial customers. We have come to the point where we need to think about an updating strategy to make it easier to deploy our newest version to customers. However, my knowledge on the matter is quite poor and I don't really know where to start.
Our main idea is to have some sort of launcher where, on startup, the software detects that a new version is available and asks the customer if he wants to download it. The problem is that I don't know where to start to put in place that strategy.
Prior to my researches, I had come accross kubernetes, docker, Jenkins, and GitLab but can't figure out if they do actually what I want. Furthermore, I have looked at Microsoft's Configuration Manager but it seemslike you can only update softs that are on your network.
Feel free to ask for any info.
Thank you in advance for your help ! :)
We have an existing cross-platform Mobile Application, that also has an accompanying web application, that uses AWS as a back end (RDS for Database, Four server instances, and a Load Balancer to distribute traffic). APK and IPA files are packaged and sent to the stores, while components are retrieved from our server per request, which enables us to reduce the number of store builds, and make the process easier for getting changes out to clients.
We are at the stage of Development that we need to move to another platform to better facilitate our fast growing client base.
Due to the conditions upon our clients, these things must be considered.
must be cross platform (Android / iOS).
must be offline based (users need to be able to access without an internet connection)
must be able to sync with an existing database when there is a connection
requires Authentication
Cloud based (? may not be the right term, but meaning the ability for us to store components on a server and have a device check for updates and download a local copy - enabling us to work and distribute fixes faster)
Ideally compatible with AWS
We are currently looking at Xamarin to facilitate us for this move, however there is a lot of documentation and plugins out there to do all sorts of different things.
As developers, we all have some .net / c# experience, however none particularly with Xamarin.
We have a particular timeline that we need to adhere to (and need to ramp up in the next couple of weeks), and right now are essentially stuck in Limbo in a research phase, as we can't afford to get some things right. We are unable to move forward until we know Xamarin (or some other framework) is able to do everything that we need it to do.
It's hard to escape from the 'code it all ourselves' mentality - especially as we don't know where to start looking in terms of third party packages for Xamarin, and their documentation itself.
A lot of documentation mentions various systems of Azure - we would not be against moving to Azure over AWS if it _had to be done*, but because of the existing infrastructure with AWS - staying with AWS is obviously the preferred option (users need to access the current system whilst we build the new system)
This stack overflow post is to ask for recommendations, comments, or other observations on anything and everything involved with the process in regards to choosing frameworks, design patterns, methodologies, third party packages, etc.
Obviously we would like to use best practises for everything moving forward for optimum scalability and cleaner, more robust code. It's just hard to know where to start!
Any input will be highly appreciated.
Cheers!
edit: I am aware that this is 'asking for recommendations' which is 'specifically off-topic'. I have read the posting guidelines about open ended discussion, and am quite confident that this case is different. There is an underlying problem here, in that we are seeking advice on combinations of frameworks and plugins that are fully compatible with all of the items in the list (above)
Let's try to breakdown each of your requirement and constraint mentioned in the question.
1. You need a offline first architecture (With Sync mechanism)
Xamarin + Azure would make a good comdo for you, as it would support offline storage out of box (With a simple PullAsync call).
Albeit there are AWS SDK available for Xamarin. Here it goes http://docs.aws.amazon.com/mobile/sdkforxamarin/developerguide/setup.html
So the call is yours. There are few other ways to achieve caching offline storage in Xamarin, you can build upon those strategy in your logic. Alternatively there is a very interesting C# library Akavache for caching and offline storage.
2. OAuth 2.0 Authentication
Xamarin has a very good library named Xamarin.Auth. Though I would not say it is very easily extendible at this but there has been some serious work going on from Xamarin on this library.
But I would say it is very easy to use. The apps I have developed so far that includes - Google OAuth, Facebook integration, Microsoft account integration. It worked fine for all of them.
3. Cloud based distribution
There are nice tools available with Microsoft. Which makes the distribution easy. Have a look at https://mobile.azure.com . Also hockeyApp is good for distribution I found.
Where to start:
A very good starting point for you would be https://channel9.msdn.com . Just go there search with keyword "Xamarin" and view some videos. May be all these cross platform dynamics will be much easier for you.
Overall I found Xamarin a cool product to work with. Because anything that can be done in native Objective C/Swift or Java can very well be done in Xamarin using C#.
First, I don't know if this is the right place to make this question but, I don't see any other place where to put it.
I would like to know how could I develop a mobile HTML5 App (using PhoneGap) with another friend, without need to have a copy of the project in more than one PC.
Could I somehow host the Code on a FTP Server and then we both could work on it for example, on Eclipse?
You need to look into using a source control system of some kind. Source control comes in many flavors, but in general it allows software developers to sync code between many servers, and allows developers to work concurrently without breaking each other's environments (imagine I have to take a component offline for many hours to code on it, but other people rely on it to do their work).
The two most common source control solutions are SVN and Git. Both of these work on Mac/Linux/PC and are documented thoroughly online.
without need to have a copy of the project in more than one PC.
How should that be possible? When want to view view something on your local computer, you must have it available on your local computer. But I think I know what you are looking for, three suggestions:
Use a cloud-based IDE. Cloud9 for example is one of the best. However, all of them tend to be slow and buggy.
Just synch the files between your computers. One of the best hosted services is Dropbox, or you can install ownCloud on your own Server.
Use a version control system. This is pretty common for software development as you can easily reproduce who made which change when and why. The best option is git and Github for hosting.
I know this is months late, but check out Adobe's Phonegap Build. Build and deploy in the cloud. They also allow you to assign a development team.

The imminent death of iDisk is a bummer. I have used it for years to easily share files with clients without asking them to boot up their FTP software.
I am curious to know if there is a way to mimic iDisk's file sharing features through Lion Server. Specifically, the ability to share links to specific files and have them downloaded through a web browser. I miss the clean interface of iDisk through MobileMe.
I realize that there are third party providers like Dropbox and YouSendIt, but it would be nice to serve the files directly from our local server. I originally thought WebDav might be the answer, but it seems that's not the case.
You will have to install additional software to get that functionality. I've used and had good luck with Boxroom (http://boxroom.rubyforge.org/) but it requires Rails which may be too much work to install if you don't need it for anything else.
Searching for "open source php file manager" turns up a range of options which should work well on Lion as it has PHP already installed. I have also seen Java alternatives, some of which run on top of WebDAV, so it is probably best to start with the development language you are most comfortable with deploying and work from there.
Sorry I couldn't be more specific, my Mini is in transit so I haven't had direct experience with Lion server yet:)
Have a look at Storage Made Easy Mac client. It works a similar way to the original iDisk but also had sync capability. See: https://storagemadeeasy.com/MacCloudTools/ and https://storagemadeeasy.com/wiki/maccloudtools/. There is a native disk piece and also a sync like dropbox piece to the App.
I am trying to find the best way to maintain a bug tracker and feature/upgrade requests for clients on web development projects. Ideally it would be an open source system we can have installed on a sub domain of our site.
This will then allow each client to login and add bugs/features/upgrade which we can hopefully keep track of.
I have been trying to use and implement trac but it just feels too "techy" and a little too complex for setup.
Any ideas?
Thanks in advance,
Shadi
UPDATE
Just to clarify, we do want a system to install on our servers, the trouble with trac is the install process in relation to what you get and how clients feel about it is a little poor. But if something is awesome but has a complex setup, that isn't a problem...
Mantis is another. Simple UI.

If you have Linux boxes, trac is much easier to install. Config takes a bit, but wasn't a problem in my experience.
I've heard good things about FogBugz. :)
If you don't want to install it yourself they have a hosted solution also.
Have you taken a look a Bugzilla? Not sure if it meets all your needs but it is free but you can get paid support. It's an open source project AFAIK.
