海外TECH	DEV Community	Three real-world examples of distributed Elixir (pt. 1)	https://dev.to/bigardone/three-real-world-examples-of-distributed-elixir-pt-1-9j6	Three real world examples of distributed Elixir pt While deploying any project to a production environment you can either scaleit vertically adding more resources to the single instance where it is running or horizontally adding multiple instances If you don t like putting all the eggs in a single basket and choose the horizontal approach Elixir offers all the necessarydistributed features that you need out of the box withoutany additional dependencies letting you build a cluster between the different instances of your application Clustering your service allows you to do very interesting stuff from spawning new processes in any instance to sending messages between cluster nodes letting you build very creative solutions Although this might sound complex in reality it is straightforward to achieve sincethese distributed capabilities are integrated into the language that you already know letting you design your applications in a totally different way Along with these post series we will explore three differentreal world use cases of distributed Elixir but before let s go back to the basics and see how to build an Elixir cluster Let s get cracking Building a simple clusterLet s generate a basic OTP application and start iterating from there ➜mix new simple cluster sup ➜cd simple clusterTo build the cluster we need two things To provide a name for the current application instance To connect the different nodes once the application starts The first one is straightforward and we can achieve it by adding the name argument to the start command ➜iex name n S mixErlang OTP erts source bit smp ds async threads jit Interactive Elixir press Ctrl C to exit type h ENTER for help iex n gt Easy right Please note the iex prompt iex n gt containing the node name we just assigned Let s start a new node in a different terminal window setting the n name ➜iex name n S mixErlang OTP erts source bit smp ds async threads jit Interactive Elixir press Ctrl C to exit type h ENTER for help iex n gt Now that we have both nodes up and running let s create the cluster by manually connecting the nodes using Elixir s Node connect iex n gt Node connect n trueiex n gt And the same from n iex n gt Node connect n trueiex n gt To confirm that everything went fine let s run Node list on each node which returns the list of nodes to which the current instance has connected iex n gt Node list n iex n gt iex n gt Node list n iex n gt Our first clustered application is ready yay However connecting manually to each of the nodes from iex is less than ideal There is a more convenient way of doing it which is adding a sys config file to the root of the project with the following content kernel sync nodes optional n n sync nodes timeout This file sets default values on the application start in this particular case sync nodes optional the list of possible nodes in the cluster sync nodes timeout the timeout to synchronize the nodes To apply this configuration let s start each node setting the erl parameter with the configuration file ➜ iex name n erl config sys config S mixErlang OTP erts source bit smp ds async threads jit Interactive Elixir press Ctrl C to exit type h ENTER for help iex n gt ➜ iex name n erl config sys config S mixErlang OTP erts source bit smp ds async threads jit Interactive Elixir press Ctrl C to exit type h ENTER for help iex n To confirm that the nodes are connected let s create a module that spawns a process on each node that observes any change in the cluster membership lib simple cluster observer ex use GenServer require Logger def start link do GenServer start link MODULE impl GenServer def init state do net kernel monitor nodes true ok state end impl GenServer def handle info nodedown node state do A node left the cluster Logger info Node down node noreply state end def handle info nodeup node state do A new node joined the cluster Logger info Node up node noreply state endThis simple GenServer calls net kernel monitor nodes on its initialization subscribing to any node status change in the cluster Therefore it receives both nodeup node and nodedown node messages whenever a node joins or leaves the cluster Let s add this generic server to the main supervision tree of the application lib simple cluster application exdefmodule SimpleCluster Application do use Application impl true def start type args do children SimpleCluster Observer opts strategy one for one name SimpleCluster Supervisor Supervisor start link children opts endendLet s start again our two nodes and see what happens If we start n we can see the following log message in n info Node up n If we stop n we can see the corresponding logger message info Node down n To test out communication between the nodes let s add a new module that sends a message to all the nodes in the cluster printing the result lib simple cluster ping exdefmodule SimpleCluster Ping do use GenServer require Logger def start link do GenServer start link MODULE name MODULE end def ping do Node list gt Enum map amp GenServer call MODULE amp ping gt Logger info end impl GenServer def init state do ok state impl GenServer def handle call ping from state do Logger info Receiving ping from inspect from reply ok node pong state endendThis GenServer has two different parts First of all it exposes a public ping function which takes all the nodes in the cluster and sends them a ping message using GenServer call This function accepts the following as the first parameter server pid name atom node By using MODULE amp we are saying Send ping to the process with the name SimpleCluster Ping in the node amp This takes us to the second part of the module the callback handle call ping from state which receives the incoming message logging the sender and responding with a ok node pong tuple Let s add this module to the main supervision tree restart our instances and see it in action lib simple cluster application exdefmodule SimpleCluster Application do def start type args do children SimpleCluster Observer SimpleCluster Ping endendiex n gt SimpleCluster Ping ping info ok n pong okiex n gt info Receiving ping from PID lt gt alias Reference lt gt Nodes have automagically connected and processes can communicate between them as we expected Nevertheless this is again far from ideal in a real world application deployed into a production environment How would we handle dynamic IPs How would we manage new nodes connecting or leaving the cluster Thankfully there is a library that addresses this for us Automatic cluster formation with libclusterlibcluster provides a mechanism for automatically forming clusters of Erlang nodes with either static or dynamic node membership offering a wide variety of strategies and even letting you create your own We will not dive too deep into its internal details in this series but you can look at its different strategies in its official docs To use it let s get rid of the sys config file and add libcluster to our application dependencies ➜rm sys config mix exsdefmodule SimpleCluster MixProject do use Mix Project defp deps do libcluster gt endendDon t forget to run the corresponding mix deps get P To create the cluster libcluster uses different strategies and in this particular case we will use the Cluster Strategy Epmd strategy in which we can set the list of hosts as we did with the former sys config file Let s go ahead and add the cluster supervisor and its configuration to the main supervision tree lib simple cluster application exdefmodule SimpleCluster Application do use Application impl true def start type args do children Cluster Supervisor topologies name SimpleCluster ClusterSupervisor SimpleCluster Observer SimpleCluster Ping opts strategy one for one name LibclusterCluster Supervisor Supervisor start link children opts end defp topologies do example strategy Cluster Strategy Epmd config hosts n n endendNow we can start both nodes without the erl flag ➜iex name n S mixErlang OTP erts source bit smp ds async threads jit warn libcluster example unable to connect to n Interactive Elixir press Ctrl C to exit type h ENTER for help iex n gt info Node up n iex n gt SimpleCluster Ping ping ok info ok n pong info Node down n Everything is working like before yay Now that we have ready the basics of a clustered Elixir application in the following postswe will implement three creative solutions around it starting with the most simple one in which we will build a singleton processacross the cluster in charge of executing a periodic task Happy coding bigardone distributed
