kandi X-RAY | kopf Summary

kopf is a Python library typically used in Programming Style, Reactive Programming, Framework applications. kopf has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has medium support. You can install using 'pip install kopf' or download it from GitHub, PyPI.

Kopf —Kubernetes Operator Pythonic Framework— is a framework and a library to make Kubernetes operators development easier, just in a few lines of Python code. The main goal is to bring the Domain-Driven Design to the infrastructure level, with Kubernetes being an orchestrator/database of the domain objects (custom resources), and the operators containing the domain logic (with no or minimal infrastructure logic). The project was originally started as zalando-incubator/kopf in March 2019, and then forked as nolar/kopf in August 2020: but it is the same codebase, the same packages, the same developer(s).

            This happens because one answer is null. In your case you have a type on your second item in your list. It has the property asnwer instead of answer which means your second item will return answer = null.

            Align Grid in RelativeLayout
            Asked 2021-Jan-26 at 09:31

            I am a novice in android studio and after trying different layouts with not really satisifying success, I am now back to Relative Layout. I want to have grid of buttons and the alignments work okay when the buttons are aligned to the end of start of a button the same size, but sometimes I want two smaller buttons underneath a bigger button, but since I can only align the left smaller button with the start of the bigger button and the right smaller button with the end of the end of the bigger button, the space between the smaller buttons is not aligned and causes all kind of problems. How do I align those two buttons in the middle?

            Here is my manifest.xml

            This could be achieved like so:

            1. Put your code in a function which takes a filename as an argument
            2. Use list.files to get a vector of all xml files in your directory
            3. Use e.g. lapply to loop over the files, which will return a list of your texts.

            What I see in your example is that the code tries to watch over the resources in the cluster. However, it uses the official client library, which is synchronous. Synchronous functions (or threads) cannot be interrupted in Python, unlike asynchronous (which also require async i/o to be used). Once the function shown here is called, it never exits and has no point where it checks for the stopped flag during that long run.

            What you can do with the current code, is to check for the stopped flag more often:

            Is it possible in Java to implement interfaces and their methods without using the keyword "implements"?
            Asked 2020-Sep-13 at 04:36

            I have homework to do (actually my girlfriend :-D) and there are some restrictions on what I can and can't do. In my NetBeans project folder there are two folders named "interfaces" and "homework". The folder "interfaces" contains interfaces and classes that are NOT allowed to edit, because said that to us xD. I am only allowed to edit the source text in the "homework" folder.

            Usually, I know it to implement interfaces in Java with the keyword "implements". But I don't know how to use it in the "homework" folder, because the "interfaces" folder already contains classes that implement the methods and logic of the interfaces, but I am not allowed to edit them.

            This is the task:

            "We provide you with various interfaces in the "interfaces" package, which you have to implement. You are only allowed to create your own implementation in the "homework" package. You may not modify the classes and interfaces of the "interfaces" package!

            The interface "TextAdventure", the methods of which you have to implement, allow you to create a text adventure game. In the "homework" package you will find a Main class that uses the TextAdventure interface to initialize various games. You can play through that game after you successfully implementing the interfaces as disired. The game scenarios are designed to help you extensively test your code. All methods of the Interface Player are available for interacting with the game. Also take a look at the GameStarter class. In this, the interaction with the player is implemented.

            The TextAdventure interface offers various methods for creating a new game. For each method, think about the cases in which it could fail. In such cases, throw a TextAdventureException. This is also made available to you in the "interfaces" package. Once the desired initial state is established, a game can be started with "startGame ()"."




            Answered 2020-Sep-13 at 04:36

            You can implement all the methods that an interface X declares without writing "implements X". But that is really nonsensical. You want that the Java compiler understands that your new class implements X. And you need that keyword on the signature of the class definition for that.

            One could think of extending a class that already implements an interface, then you don't have to repeat the keyword "implements X". But that is really just about not using that keyword in your source code.

            In your case, the key part is to understand that not all interfaces in that package interfaces have an implementation so far. Your starting point: write down just the list of names of classes and interfaces that exist in the input you received. Then see which interface has implementations, and which have not!

            I think the problem here is the foreach. It appears as though your sql statement is expecting all the values in one go but you loop the outer nodes so the first loop you have some of the nodes and then the next time around the rest.

            If you know the outer nodes then remove the foreach loop altogether and reference the full node path. e.g.

            Optimize API for reducing the segments and eliminating ES deleted docs not working
            Asked 2020-Mar-01 at 01:13

            This is in continuation of my previous question Does huge number of deleted doc count affects ES query performance related to deleted docs in my ES index.

            As pointed in the answer, I used optimize API as I am using the ES 1.X version where force merge API is not available but after reading about optimize API github link(provided earlier as couldn't find it on ES site) by Say Bannon founder of elastic, looks like it does the same work.

            I got the success message for my index after running the optimize API, but I don't see total count of deleted docs decreasing and I am worried as when I checked the segments of my index using segments API, I see there are more than 25 segments for each shard and every shard is holding 250-1 gb of data in memory and almost 500k docs, while I see there are some shards where there is few deleted docs.

            So my question are:

            1. My index is having multiple shards across multiple data nodes and when I ran optimize API using only 1 node URL, then does it only merges the segments on that node?
            2. In segment API result it shows the node-id like "node": "f2hsqeamadnaskda", while I am using KOPF plugin and have custom names for my data nodes, so How can I relate this cryptic node name to my human readable node name to identify whether statement 1 is correct or not?
            3. As there is no documentation available on optimize API, is it possible to merge segments on all shards across all nodes in single shot? and do I need to make index read-only before applying it?


            Answered 2020-Mar-01 at 01:13
            1. It merges the segment based on the segment state, size and various other params, also it merges the segments of all the shards of an index. Looks like in your example you have a huge number of segments that are not being picked up optimize API, which makes you think that merge works on a particular node shard. You can give additional query param max_num_segments={your desired no of segments} and see it should reduce the segments of a shard to the given number.
            2. Node id you can find using API with http://:9200/_cat/nodes?v&h=id,ip,name , it gives output in below format

            id ip name
