海外TECH	DEV Community	Kubernetes Cordon: How It Works And When To Use It	https://dev.to/castai/kubernetes-cordon-how-it-works-and-when-to-use-it-pp5	Kubernetes Cordon How It Works And When To Use ItKubernetes gives you the option to administer and maintain nodes manually Using kubectl you can easily create a node object and modify nodes for example set a label or mark it unschedulable This is where Kubernetes cordon comes in What is the Kubernetes cordon command and how do you use it Read this article to find out What is Kubernetes cordon Kubernetes cordon is an operation that marks or taints a node in your existing node pool as unschedulable By using it on a node you can be sure that no new pods will be scheduled for this node The command prevents the Kubernetes scheduler from placing new pods onto that node but it doesn t affect existing pods on that node  To mark a node unschedulable all it takes is running this command kubectl cordon NODENAMENote that you can run pods that are part of a DaemonSet on an unschedulable Node That s because DaemonSets usually provide node local services that should be running on the node even if it s marked as unschedulable and drained of workloads When do you use the Kubernetes cordon Nodes in a Kubernetes cluster may require maintenance be it replacing hardware components in a self hosted installation updating the node s kernel or resizing its compute resources from a cloud provider Kubernetes cordon and drain prepare your application for node downtime by letting workloads running on a target node get rescheduled to other ones You can then safely shut the node down and remove it from your cluster confident that this doesn t impact service availability in any way How does Kubernetes cordon work step by step guideStep Cordoning a nodeBy cordoning a node you mark it as unavailable to the scheduler This makes the node not eligible to host any new pods that will be added to your cluster To place a cordon around a named node use this command kubectl cordon node The existing pods on this node won t be affected by this and will remain accessible  Want to check which nodes are cordoned at the moment Use the get nodes command kubectl get nodesNAME  STATUS           ROLES        AGE VERSIONnode Ready SchedulingDisabled  control plane master m  v All the cordoned nodes will appear with the status SchedulingDisabled Step Draining a nodeTo empty the node from the remaining pods you need to drain it This process evicts the pods so they can be rescheduled to other nodes in your cluster You can gracefully terminate pods before forcing them to be removed from the node you re planning to drain To start the drain procedure run kubectl drain specifying the name of the node you re draining kubectl drain node node node already cordonedevicting pod kube system storage provisionerevicting pod default nginx cb zszddevicting pod kube system coredns d dplxpod storage provisioner evictedpod nginx cb zszdd evictedpod coredns d dplx evictednode node evictedNote In practice draining without ignoring daemonsets hardly happens as illustrated here How does the drain procedure work First we have Kubernetes cordoning it cordons the node if you haven t done that manually Next it evicts running pods even if there is no space to reschedule them Once the node is empty you can shut it down or destroy it The cordon assures that no new workloads can be scheduled on this node once the drain is completed What happens if your pods have long grace periods Kubernetes node draining might take a while if your pods happen to have long grace periods This might become a problem if you re looking to take a node offline quickly  You can always use the grace period flag to override your pod termination grace periods and force an instant eviction kubectl drain node grace period Use this one carefully Some workloads might not respond well when you force them to stop without having the chance to clean up Another command worth knowing is one for draining node even if there are no pods managed by a ReplicationController Job or DaemonSet on it kubectl deain node forceHow do you undrain uncordon a node in Kubernetes It s possible to undrain or uncordon a node in Kubernetesn by marking this node as schedulable Use the following command kubectl uncordon NODEUsing Kubernetes cordon for cluster optimizationSuppose you analyze your cluster with a third party optimization solution and discover a great potential for cost savings But to get there you need to change the compute resources your cluster is running on This is where Kubernetes taint comes in handy Our customers can maximize their cost savings immediately by using Evictor a mechanism that looks for inefficiencies and compacts your pods into fewer nodes creating empty nodes that will be removed by the Node deletion policy  Once you install CAST AI using this guide and connect your cluster you can set the Evictor policy Your next step is to get rid of your existing nodes and let CAST AI create an optimized cluster Note that depending on your workload configuration this might cause some downtime Evictor plays it safe by design not to cause any downtime but some settings can be overwritten for it to be more aggressive This is what Evictor looks like in action One node in red below is identified as a candidate for eviction Evictor automatically moves the pods to other nodes this i called “bin packing Once the node becomes empty it s deleted from the cluster Go back to step One node is deleted And at the end of the process nodes remain In minutes Evictor deleted nodes and left nodes running to optimize the setup and cut costs Automate Kubernetes node cordoning and drainingChanging the compute resources your nodes run on manually quickly becomes time consuming if you re dealing with many nodes You can let CAST AI do the job and do the node cordoning and draining for you as part of its automated optimization mechanisms Connect your cluster in a read only mode to find out how much you could save and how to get there You re underway to simplify KubernetesAutomate Kubernetes and optimize your resource utilization for a lower cloud bill	2022-11-18 11:23:15
海外TECH	DEV Community	Introduction to Supabase — The Firebase alternative	https://dev.to/shreyvijayvargiya/introduction-to-supabase-the-firebase-alternative-46fg	Introduction to Supabase ーThe Firebase alternativewith SQL database instead of No SQL Under the HoodThe story begins when I read the tweet by one of its co founders Supabase is the name of the product and they claim them to be the straight firebase alternative I got excited about a firebase alternative meaning a more tabular database structure or maybe easy to build many to many relations within collections Let s dive into the general concept of supabase OverviewSupabase claims to be the open source firebase alternative in the market It accords with creating the backend in less than minutes In addition it helps developers to create a project with a Postgres Database Authentication real time subscription and Storage Typically all the things firebase is currently serving but the only difference is the database collection Difference between Supabase and FirebaseAt this point when supabase is still growing or let s say in the beta phase so we cannot compare the two of them Firebase is a widely used and accepted backend tool for many companies nowadays It s easy to integrate and trustworthy backed by google whereas supabase has not penetrated the production level market AuthenticationSupabase and firebase are almost on the same page in handling the authentication The method to sign in or sign out the user using any provider such as Google email and password work almost the same way as firebase For adding authentication for different providers the execution is almost identical for firebase and supabase They both provide the box method to deal with the authentication and its corresponding form For example authenticating the user using email and password is relatively straightforward const loginWithEmailAndPassword async gt const data Users error await supabase auth sign email shrey gmail com password You must connect your client side application to the supabase using the supabase key and API URL I will cover a new story to explain how to connect and add supabase authentication to your application DatabaseSupabase uses Postgres as a database it works around tables instead of No SQL or Mongo DB They provide a solid intention behind choosing Postgres as a database You can read more about the architecture and database they choose in the below link Docs“We believe that no other database on the market offers the scalability and functionality required to compete with Firebase legitimately ーThese were their exact words in deliberately choosing Postgres as a database Now everything will be a table every collection you create will be a table consisting of columns and each new element will be added in a new row Like the Postgres database every column has a schema declaring the fashion of storing the values While creating a table in the Supabase dashboard you will be asked to make these schemas of columns Working with TablesYou don t need too much understanding of SQL tables to work around a supabase database they are tables just like a spreadsheet Out of the box supabase provides a SQL editor for SQL developers to work around the database within the dashboard Providing a SQL editor nullified a lot of scalable hindrances In the future when having more than K users you need a data analyst to work around SQL database writing SQL queries in that case having pre existing SQL editor will help developers within the organisation deal with the database efficiently StorageOne cool thing about the storage bucket in supabase is uploading files directly via the dashboard Still I am sceptical about polluting the database when allowed to upload via a dashboard directly Never mind I love the interface for storing files and being easy to handle and work around Storage provided by supabase is just like firebase storage Only the naming convention of methods and the layout for the dashboard are different DocsThe only part where I don t trust or find google good at is docs Documentation for Firebase is not too good you have to rely on StackOverflow to deal with firebase issues So far I have found supabase documentation well articulated and easy to grasp Spending a few minutes on the dashboard will redirect you to all the required pages One of the best pieces of documentation I ve read so far reach out to the link below to read it You need to log in to reach this page Future amp ConclusionAt this point in time we cannot surely tell the future of supabase Yes overall the product looks fine to me the dashboard UI is simple and easy to use authentication database is not too difficult to deal with It s a good alternative for firebase users who are hard geek SQL lovers and working around tables are their every time forte What the future holds for the subbase is a question companies should adopt the new style of creating databases and since firebase is booming a lot they too have heavy competition I will keep covering more stories about supabase in future until next time have a good day people Keep developingShreyiHateReading	2022-11-18 11:21:38
