openshift Authentication

 

  • Authentication: OpenShift has several built-in authentication methods to allow granular access to OpenShift projects:
    • Local authentication
    • LDAP authentication
    • Request header authentication
    • Keystone authentication
    • GitHub authentication
    • Internal Image Registry: OpenShift uses an internal registry to store images in OpenShift that are ready to be deployed on OpenShift nodes. It is also used for S2I builds.
    • GUI and web console: OpenShift provides an easy-to-use web interface, powerful enough to create, build, deploy, update, and troubleshoot OpenShift projects and microservice applications running inside OpenShift.
    • SCM Integration: OpenShift has built-in integration with Git. This solution is tightly coupled with an image builder.
    • Image builders: Process that is used to transform image parameters or source code into a runnable image.
    • CI/CD Integration: OpenShift provides very flexible integration with Jenkins for Continuous Integration and Continuous Delivery pipelines. It scales the pipeline execution through Jenkins provisioning in containers. This allows Jenkins to run as many jobs in parallel as required and scales solutions on demand out of the box.
    • Additional Kubernetes resource extensions: There is a set of resources added to Kubernetes by OpenShift:
      • Deployment Configurations (DC): This is a set of pods created from the same container image.
      • Build Configurations (BC): Primarily used by S2I to build an image from source code in Git.
      • Routes: DNS hostname service used by the OpenShift router as an ingress point for OpenShift applications,
    • REST API: In addition to the Kubernetes API, OpenShift provides its own API interface to leverage all the features of automation and seamless integration with external platforms, other automation frameworks, and DevOps solutions.

Read and Navigate XML - Beautiful Soup

 ### How to read and navigate XML There is a Python library called BeautifulSoup, which makes reading in and parsing XML data easier. Here is the link to the documentation: [Beautiful Soup Documentation](https://www.crummy.com/software/BeautifulSoup/) The find() method will find the first place where an xml element occurs. For example using find('record') will return the first record in the xml file: ```xml <record>   <field name="Country or Area" key="ABW">Aruba</field>   <field name="Item" key="SP.POP.TOTL">Population, total</field>   <field name="Year">1960</field>   <field name="Value">54211</field> </record> ``` The find_all() method returns all of the matching tags. So find_all('record') would return all of the elements with the `<record>` tag. Run the code cells below to get a basic idea of how to navigate XML with BeautifulSoup. To naviga...

difference-between-stream-processing-and-message-processing

 difference-between-stream-processing-and-message-processing Message Processing implies operations on and/or using  individual  messages. Stream Processing encompasses operations on and/or using individual messages as well as operations on collection of messages as they flow into the system. For e.g., let's say transactions are coming in for a payment instrument - stream processing can be used to continuously compute hourly average spend. In this case - a sliding window can be imposed on the stream which picks up messages within the hour and computes average on the amount. Such figures can then be used as inputs to fraud detection systems Although Rabbit supports streaming, it was actually not built for it(see Rabbit´s web site) Rabbit is a Message broker and Kafka is a event streaming platform. Kafka can handle a huge number of 'messages' towards Rabbit. Kafka is a log while Rabbit is a queue which means that if once consumed, Rabbit´s messages are not there anymore in c...

WordNet in Python

Image
  WordNet   is an English dictionary which is a part of   Natural Language Tool Kit   (NLTK) for Python. This is an extensive library built to make   Natural Language Processing   (NLP) easy. Some basic functions will be discussed in this article. To start using WordNet, you have to import it first: from  nltk.corpus  import  wordnet Synsets and Lemmas In WordNet, similar words are grouped into a set known as a  Synset  (short for  Synonym-set ). Every Synset has a name, a part-of-speech, and a number. The words in a Synset are known as  Lemmas . Getting Synsets The function  wordnet.synsets('word')   returns an array  containing all the Synsets related to the word passed to it as the argument. Example: print ( wordnet.sysnets ( 'room' )) Output: [Synset(‘room.n.01’), Synset(‘room.n.02’), Synset(‘room.n.03’), Synset(‘room.n.04’), Synset(‘board.v.02’)] The method returned five Synsets; four have the name...
