# Entando CLI

# Overview

The Entando Command Line Interface (CLI) provides a set of commands that accelerate the developer experience by assisting the developer with common tasks such as quickly installing a new copy of Entando, generating an Entando project via JHipster, deploying an Entando Bundle, etc.

# Installation

# Prerequisites

The basic requirements for the CLI vary depending on the category of developer tasks. The Entando CLI is able to install secondary dependencies using the ent check-env command as described here.

Category	Prerequisite
Basic Development	git or git for windows (opens new window)
	nvm or nvm for windows (opens new window)
Install Entando in a local VM	multipass (opens new window)
Build and publish Entando Bundles	docker and docker-compose
	a git repository for the bundle artifacts
	a Docker Hub account (or organization) for microservice Docker images
Deploy an Entando Bundle	a Kubernetes cluster with admin access. This could be a local cluster (created via the CLI or manually) or a shared remote cluster.

TIP

If you follow the automated option in Getting Started, then the CLI will be installed for you along with an Ubuntu VM containing k3s Kubernetes and a quickstart Entando application.

# Install the CLI

Install the current offical release of the CLI via the following command.

curl -L https://get.entando.org/cli | bash

# Check Environment

Use the check-env command to prepare your environment for development. This will verify the presence of additional dependencies (such as git, curl, java, JHipster, etc.) as well as the appropriate versions for your specific Entando instance. In most cases check-env will automatically install those dependencies and will prompt the developer for guidance or approval as needed.

ent check-env develop

# Update the CLI

The CLI can be updated to the latest version (corresponding to your Entando version) using the following command. You should run ent check-env develop after updating the CLI in case any dependency versions have changed.

bash <(curl -L "https://get.entando.org/cli") --update

  - Check the dependencies (ent check-env --help)

Check the help text (--help) for any command to see its specific options, e.g. ent check-env --help.

# Project Management

These are common sequences for an Entando project.

# Project Setup

Setup a project directory

mkdir testProject && cd testProject

Generate the project skeleton using the JHipster-based Entando Blueprint.

ent jhipster --blueprints entando

Generate an entity and MFEs.

ent jhipster entity Conference

Build the new project. Using the ent-prj wrapper saves having to build each part of the project individually. The first run can be slower due to node downloads for any MFEs.

ent prj build

See this tutorial for more details.

# Prepare and Publish a Bundle

Use the publication system (pbs) to assemble your Entando project into a bundle that can be loaded into Kubernetes. You'll need your github credentials, a github repository to hold your bundle artifacts, and a Docker Hub account or organization.

Initialize the bundle directory

ent prj pbs-init

Publish the build artifacts to github and Docker Hub

ent prj pbs-publish

Create a Kubernetes Custom Resource and apply it to your Entando instance. You can modify the target namespace parameter (-n) if you changed it from the default.

ent prj generate-cr | ent kubectl apply -n entando -f -

See this tutorial for more details.

# Run a Project locally

Startup Keycloak. This uses docker-compose under the hood.

ent prj ext-keycloak start

Startup the backend microservices

ent prj be-test-run

Startup one or more of the frontend widgets, each from its own shell.

ent prj fe-test-run

See this tutorial for more details.

Alternatively, you can perform a completely clean install of the CLI by removing your ~/.entando directory and then reinstalling the CLI per the instructions above. This will also remove the private copies of JHipster, Entando Blueprint, etc.

rm -rf ~/.entando.

# Bundle Commands

Use the ent bundler command to prepare a bundle for publication or extract a bundle from an application.

Prepare a bundle custom resource from a Git repository. The project command (ent prj generate-cr) provides a wrapped version of this command. See the help for options including the bundle name, description, repository, etc. The output of this command is a yaml file which can be piped to a file or directly to ent kubectl for application to Kubernetes.

  ent bundler from-git

See this tutorial for an example using this command.

Point the bundler to an existing Entando application and extract its components (pages, content, etc.) and static assets into a custom bundle. You can use this bundle to migrate Entando components from one environment to another (e.g. Dev to QA), to provide a template for building a new Entando application, or as the skeleton of an Entando solution. The bundler provides an interactive mode which allows you to identify the components to be exported from the application. The output of this command is the same bundle folder structure created by an Entando project including a top-level descriptor file.

  ent bundler from-env

You will need to provide an env.json file in the same directory where the bundler is run. This is used to configure the application URLs and client credentials.

{
   "coreBaseApi": "http://<YOUR-DOMAIN-OR-IP>/entando-de-app",
   "k8ssvcApi": "http://<YOUR-DOMAIN-OR-IP>/k8s",
   "clientId": "<YOUR-CLIENT-ID>",
   "clientSecret": "<YOUR-CLIENT-SECRET>"
}

See this tutorial for more instructions on exporting a bundle including how to setup your env.json.

# Diagnostic Commands

The following commands can be useful to more quickly understand what is happening with an Entando Application. If you followed the Getting Started steps to setup Entando then the CLI was automatically installed in the Multipass VM and you can run these commands from there.

ent app-info display basic information about Kubernetes and the Entando resources (e.g. namespace, pods, ingresses)

ent app-info

ent pod-info display the kubectl describe and kubectl logs for each of the major Entando pods in a given namespace.

ent pod-info

ent diag list the current pods in a given Entando namespace and prepare a diagnostic tar.gz containing kubectl describe and kubectl logs for each of the major Entando pods. This can be highly useful when working with Entando Support.

ent diag

Output:

ubuntu@entando:~$ ent diag
Please provide the namespace (entando):
## DNS rebinding protection TEST
