海外TECH	DEV Community	Kubernetes GitOps: A Beginner's Guide with a Hands-On Tutorial	https://dev.to/pavanbelagatti/kubernetes-gitops-a-beginners-guide-with-a-hands-on-tutorial-56de	Kubernetes GitOps A Beginner x s Guide with a Hands On TutorialKubernetes has become the talk of the town for many years now It has revolutionized the orchestration of containers and has become a leader in this field Many developers love working with Kubernetes While organizations prefer deploying applications on Kubernetes to cope with the scale and demanding resources a new approach is trending regarding Kubernetes related deployments GitOps Yes GitOps provides a smooth way and a set of practices to leverage simple tools like Git to manage infrastructure and application deployments By combining Kubernetes and GitOps organizations can reap the enormous benefits of flexibility agility scale performance efficiency and faster feature delivery In this guide to Kubernetes and GitOps I have a step by step beginner level tutorial to start implementing GitOps with Kubernetes It is time to take your application deployment to the next level Let s get started Simple GitOps WorkflowGitOps basically works on the principle of making Git the source of truth including moving everything to code and storing and maintaining everything in Git When it comes to deployment make use of an operator to deploy what is configured in Git and Yaml in a declarative fashion Since all the developers are primarily friendly with Git GitOps simplifies their complex workflow So when it comes to Kubernetes the app code container images and all related manifest files will be stored in Git and any changes are made through Git as a single source of truth Note The above content is taken from my other GitOps article written on the Dev community Read Today we will show you how to get started with the GitOps approach for your application in the below tutorial PrerequisitesIn this tutorial we will use a continuous delivery tool such as Harness to do GitOps Hence create a free Harness account It uses Argo CD as a Service GitHub account and a sample repo to experiment with I have a sample repo you can fork it and use TutorialSignup to Harness account verify your email and sign back in again to set up the GitOps pipeline You will be presented with the below deployment options Kubernetes and Kubernetes with GitOps Select Kubernetes with GitOps and continue You don t have to worry about any set up and installation Harness takes care of everything It connects to Harness by provisioning hosted agent You can click provision and wait for some time to get green checkbox for your agent Once the agent gets installed successfully get to the next configuration This is where we provide simple details like source authentication and Git details Select Git and own source code from the options Add our Git repo link Note Above shown is my GitHub repo link you should add your repo link the one you forked at the beginning of this tutorial Once you add these details make sure to add Anonymous to authenticate your details BTW its a public repo and hence no authentication is needed with username and password Make sure the authentication is successful Next let s add the other required Git details as shown below Select Target revision as master and Path as helm guestbook Next select Harness Hosted to test the GitOps workflow You can choose self managed too But for this tutorial we will select Harness Hosted Click the Connect to Cluster button and make sure the connection is successful Next you will see the last step where we are all set to deploy the application Click on Create and Sync Application This is the GitOps dashboard you will enter where all your GitOps details will be present You will see the Sync status running In a minute or two we can see the successful message You can check each tab starting from the Resource View These are the App Details tab features shown below In the same tab you can see the sync policy it is set as manual change it to Automated This means when any changes happen to your GitHub repo the GitOps agent will pick those changes automatically and syncing will happen in an automated fashion The next tab shows the sync status of the application The manifest tab shows the manifest details of the application In the main dashboard go to the GitOps tab is the entry to your GitOps workflows Once you click on the GitOps tab you should see the overview of your GitOps dashboard If you click on the application you should see our application You click on it and go to the Resource view You will see replicas running as mentioned in our values yaml file This is our values yaml file from the example repo Default values for helm guestbook This is a YAML formatted file Declare variables to be passed into your templates replicaCount image repository gcr io heptio images ks guestbook demo tag pullPolicy IfNotPresentservice type ClusterIP port ingress enabled false annotations kubernetes io ingress class nginx kubernetes io tls acme true path hosts chart example local tls secretName chart example tls hosts chart example localresources We usually recommend not to specify default resources and to leave this as a conscious choice for the user This also increases chances charts run on environments with little resources such as Minikube If you do want to specify resources uncomment the following lines adjust them as necessary and remove the curly braces after resources limits cpu m memory Mi requests cpu m memory MinodeSelector tolerations affinity Now change the replicaCount from to You should see that the GitOps agent will see this difference and picks it up Suddenly the application configuration goes out of sync Takes some time to match up and gets back to the healthy and successful sync state You can see the second deployment as Automated since we changed the sync policy to automated Well after some time the application configuration state shows a healthy and successful sync state In the above resource view you can see that the replicas have been matched to as we wanted replicas As GitOps uses Git as the source of truth it keeps a record of who committed what code and if someone changed something in the repository You can see this from our GitOps dashboard Once you click on that id number shown in red box above you can see what changed This is how intuitive and simple it is to deploy applications via the GitOps way using Harness CD Kubernetes GitOps is a fantastic approach to handling complex cloud native application deployments Since it uses a simple tool like Git that developers already know it becomes easy to learn and streamline your application deployment approach Make your applications more stable agile and efficient with Kubernetes GitOps Get started with GitOps today	2023-04-08 05:49:34
海外TECH	DEV Community	Tutorial: DNS Enumeration using Python	https://dev.to/jsquared/tutorial-dns-enumeration-using-python-1339	Tutorial DNS Enumeration using Python Explanation of DNS EnumerationDNS Enumeration is a method of collecting data about a domain s configurations DNS or the Domain Name System translates human readable domain names for example www amazon com to machine readable IP addresses something such as The process of DNS Enumeration returns various important information about the target like DNS record types host names IP addresses and much more depending upon the configuration of that target system The main objective of DNS enumeration is to collect as much information as possible about a particular victim to identify potential vulnerabilities In this article I will show you how you can perform DNS enumeration using the Python language We will be utilizing the dnspython library that will help us carry out DNS requests which will return us with DNS records for the website we choose to install dnspython all you need to do is run this command pip install dnspythonWhen you have finished installing the library create a new file called dns enumeration py or whatever you want to call it The Coding PartTo begin with we need to specify the domain we want to analyze we will use twitter com and what kind of DNS record types we want the program to return For this tutorial we ll just have the program return the six most common DNS record types import dns resolver Set the target domain and record typetarget domain twitter com using twitter as an examplerecord types A AAAA CNAME MX NS SOA TXT Don t forget to import the library You might be asking what is a DNS record type You can think of a set of DNS records like a business listing on Yelp That listing will give you a bunch of useful information about a business such as their location hours services offered etc All domains are required to have at least a few essential DNS records for a user to be able to access their website using a domain name and there are several optional records that serve additional purposes In this case the record types will give us information about the domain like the IP address IPV address which server contains the DNS records etc Now we can move on to creating a DNS resolver as well as creating the code that will perform the DNS lookup Create a DNS resolverresolver dns resolver Resolver for record type in record types Performs DNS lookup for the defined domain and record type try answers resolver resolve target domain record type except dns resolver NoAnswer continueA DNS resolver also known as a resolver is a server on the Internet that converts domain names into IP addresses When you use the Internet every time you connect to a website using its domain name your computer needs to know that website s IP address So your computer contacts a DNS resolver and gets the current IP address of the domain you want to access Last part is we need to print out the results from the queries this is pretty simple Prints the results print f record type records for target domain for rdata in answers print f rdata f strings are string literals that have an f at the beginning and curly braces containing expressions that will be replaced with their values When you run the program you should get an output that looks like this depends on what domain you choose And that s the end of the tutorial If you want to dive further here are some links that I provided for you to read more If you liked this article consider liking it and following me If you want to see more tutorials like this in the future comment down below Full source code Jsquared	2023-04-08 05:14:03
