The language in which the template is written according to Hashicorp Configuration Language (HCL).You can download the consul-template from this page.Try it out by using the following command −$ ./consul-template -hThe output would be as shown in the following screenshot.If you wish to move this binary to a more prominent space, so that it is available for the user every time. You can type in the following commands −$ chmod +x consul-template$ sudo mv consul-template /usr/share/bin/For demo purposes, we are going to use a sample configuration of nginx to be used as our service. You can try out more demos at or better write down your own template.$ vim /tmp/nginx.conf.ctmplThe output would be as shown in the following screenshot.The config file may look like −{{range services}} {{$name := .Name}} {{$service := service .Name}}upstream {{$name}} { zone upstream-{{$name}} 64k; {{range $service}}server {{.Address}}:{{.Port}} max_fails = 3 fail_timeout = 60 weight = 1; {{else}}server 127.0.0.1:65535; # force a 502{{end}}} {{end}}server { listen 80 default_server; location / { root /usr/share/nginx/html/; index index.html; } location /stub_status { stub_status; } {{range services}} {{$name := .Name}} location /{{$name}} { proxy_pass } {{end}}}Now using the consul template binary file, please run the following commands −$ consul-template \ -template = "/tmp/nginx.conf.ctmpl:/etc/nginx/conf.d/default.conf"With the previous command the process has started. You can later open up another terminal and view the nginx.conf file being completely rendered using the following command.$ cat /etc/nginx/conf.d/default.confThe output would be as shown in the following screenshot.

What is Consul and use cases of Consul?

Consul has many integrations with Kubernetes. You can deploy Consulto Kubernetes using the Helm chart or Consul K8s CLI, sync services between Consul andKubernetes, run Consul Service Mesh, and more.This section documents the official integrations between Consul and Kubernetes.Consul Service Mesh:Consul can automatically inject the Consul Service Meshsidecar into pods so that they can accept and establish encryptedand authorized network connections with mutual TLS. And because Consul Service Meshcan run anywhere, pods and external services can communicate with each other over a fully encrypted connection.Service sync to enable Kubernetes and non-Kubernetes services to communicate:Consul can sync Kubernetes services with its own service registry. This service sync allowsKubernetes services to use Kubernetes' native service discovery capabilities to discoverand connect to external services registered in Consul, and for external servicesto use Consul service discovery to discover and connect to Kubernetes services.Additional integrations: Consul can run directly on Kubernetes, so in addition to thenative integrations provided by Consul itself, any other tool built forKubernetes can leverage Consul.There are several ways to try Consul with Kubernetes in different environments.TutorialsThe Getting Started with Consul Service Mesh trackprovides guidance for installing Consul as service mesh for Kubernetes using the Helmchart, deploying services in the service mesh, and using intentions to secure servicecommunications.The Migrate to Microservices with Consul Service Mesh on Kubernetescollection uses an example application written by a fictional company to illustrate why and how organizations canmigrate from monolith to microservices using Consul service mesh on Kubernetes. The case study in this collectionshould provide information valuable for understanding how to develop services that leverage Consul during any stageof your microservices journey.The Consul and Minikube guide is a quick step-by-step guide for deploying Consul with the official Helm chart on a local instance of Minikube.Review production best practices and cloud-specific configurations for deploying Consul on managed Kubernetes runtimes.The Consul on Azure Kubernetes Service (AKS) tutorial is a complete step-by-step guide on how to deploy Consul on AKS.

Consul Deployment Guide - Consul by HashiCorp

IntroductionProblem Once customers that are using auto_encrypt (enableAutoEncrypt) attempt to upgrade to grpc and grpc_tls, they are facing "transport: Error while dialing dial tcp x.x.x.x:8502: connect: connection refused" errors and inability to connect clients to servers.Looking at documentation, it can be difficult to differentiate which port should be set for grpc and grpc_tls in both Consul VM and Consul-k8s environments.Prerequisites:Upgrading Consul version to CauseOnce upgrade is done and the grpc and grpc_tls ports are not being matched correctly, we will end up with servers that are not listening on the correct gRPC ports. We will observer errors like: "transport: Error while dialing dial tcp x.x.x.x:8502: connect: connection refused" and cluster instability.grpc and grpc_tls ports could be mixed unintentionally and this can cause problems in environments where Consul server is outside Kubernetes cluster, since consul-k8s defaults to 8502, as noted in the Helm chart for both client and server settings, as well as in the changelog. It is recommended to 8503 to be used for grpc_tls at the Consul server side Note that Consul-k8s does not support mTLS (for now within 1.14.x)Solutions:In the Consul server config (VM), you need to to have verify_incoming = false for grpc, so that traffic coming from consul-k8s client cluster to Consul VM server won't be mTLS checked, hence it would be allowed.In the Consul server config (VM), you need to to have grpcand grpc_tls ports defined (grpc = 8502and grpc_tls = 8503).In Consul-k8s side, you need to have externalServers.grpcPort:8503 defined in your Helm chart.It is better to use 8503 for grpc_tls to follow the consul convention, as traditionally 8502 was used for grpc, where 8502 used to inherit its TLS settings from the HTTPS settings.Outcomeconsul_server_config.hclserver = truebootstrap = truelog_level = "debug"ui_config { enabled = true}datacenter = "dc1"node_name = "server-1"bind_addr = "192.168.64.1"client_addr = "0.0.0.0"data_dir = "./data"tls

For demonstration purposes, we are going to use consul agent in the developer mode using the -dev mode. Just for the local machine setup, we are going to do a single system consul setup. Please do not use this single node consul cluster in your production. As Hashicorp already mentions it in the case scenario of a single node consul cluster, the data loss is inevitable.Installing ConsulConsul can be installed via the Downloads page at www.consul.io/downloads.htmlYou can extract the binary package in your Downloads section of your machine.$ cd Downloads$ chmod +x consul$ sudo mv consul /usr/bin/Now let us start using consul using the -dev flag.$ consul agent -dev -data-dir=/tmp/consulThe output would be as shown in the following screenshot.Now you can check your consul members using the following command.$ consul membersThe output would be as shown in the following screenshot.If you want to join other nodes to this node −$ consul join Alternatively, you can run the following command on Node 2 & 3 −$ consul join Using the Command LineThe command line of consul consists of several different options, some of the most commonly used ones are as follows −agent − which runs a Consul agent.configtest − to validate a config file.event − to start up a new event.exec − to execute a command on Consul nodes.force-leave − forcing a member of the cluster to leave the cluster.info − it provides us the debugging information for operators.join − to make a Consul agent join the cluster.keygen − to generate a new encryption key.keyring − to manage gossip layer encryption keys.kv − to interact with the key-value store.leave − to leave the Consul cluster and shut it down without force.lock − to execute a command to hold down a lock.maint − to control node or service maintenance mode.members − it lists the members of a Consul cluster.monitor − it streams logs from a Consul agent.operator − it provides us a cluster of tools for Consul operators.reload − it triggers the agent to reload configuration files.rtt − it estimates network round trip time between nodes.snapshot − it saves, restores and inspects snapshots of Consul server state.version − to print the current Consul version.watch − to Watch out for changes in the Consul.Consul TemplateThe consul-template provides us a daemon that queries the Consul instance and updates any number of specified templates on the file system.

The existing ports.grpc configuration no longer supports encryption. As of version 1.14, ports.grpc_tls is the only port that serves encrypted gRPC traffic.
