+# Camel AWS Kinesis Firehose Source Basic Example
+
+This example demonstrates how to get started with Camel based Knative sources
by showing you some of the most important
+features that you should know before trying to develop more complex examples.
+
+You can find more information about Apache Camel and Apache Camel K on the
[official Camel website](https://camel.apache.org).
+
+## Before you begin
+
+Read the general instructions in the [root README.md file](../README.md) for
setting up your environment and the Kubernetes cluster before looking at this
example.
+
+Make sure you've read the [installation
instructions](https://camel.apache.org/camel-k/latest/installation/installation.html)
for your specific
+cluster before starting the example.
+
+You should open this file with
[Didact](https://marketplace.visualstudio.com/items?itemName=redhat.vscode-didact)
if available on your IDE.
+
+You must create an AWS Kinesis Firehose delivery stream named `stream` and
point it to an S3 bucket called `datalake` followed by a random number on your
AWS account.
+
+## Requirements
+
+<a href='didact://?commandId=vscode.didact.validateAllRequirements'
title='Validate all requirements!'><button>Validate all Requirements at
Once!</button></a>
+
+**Kubectl CLI**
+
+The Kubernetes `kubectl` CLI tool will be used to interact with the Kubernetes
cluster.
+
+[Check if the Kubectl CLI is
installed](didact://?commandId=vscode.didact.cliCommandSuccessful&text=kubectl-requirements-status$$kubectl%20help&completion=Checked%20kubectl%20tool%20availability
"Tests to see if `kubectl help` returns a 0 return code"){.didact}
+
+*Status: unknown*{#kubectl-requirements-status}
+
+**Connection to a Kubernetes cluster**
+
+You need to connect to a Kubernetes cluster in order to run the example.

+
+### Optional Requirements
+
+The following requirements are optional. They don't prevent the execution of
the demo, but may make it easier to follow.
+
+**VS Code Extension Pack for Apache Camel**
+
+The VS Code Extension Pack for Apache Camel provides a collection of useful
tools for Apache Camel K developers,
+such as code completion and integrated lifecycle management. They are
**recommended** for the tutorial, but they are **not**
+required.
+
+You can install it from the VS Code Extensions marketplace.
+
+[Check if the VS Code Extension Pack for Apache Camel by Red Hat is
installed](didact://?commandId=vscode.didact.extensionRequirementCheck&text=extension-requirement-status$$redhat.apache-camel-extension-pack&completion=Camel%20extension%20pack%20is%20available%20on%20this%20system.
"Checks the VS Code workspace to make sure the extension pack is
installed"){.didact}
+
+*Status: unknown*{#extension-requirement-status}
+
+## 1. Preparing the namespace
+
+Let's open a terminal and go to the example directory:
+
+```
+cd 05-aws-kinesis-firehose-source-basic
+```
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$cd%2005-aws-kinesis-firehose-source-basic&completion=Executed%20command.
"Opens a new terminal and sends the command above"){.didact})
+
+
+We're going to create a namespace named `aws-kinesis-firehose-event-source`
for running the example. To create it, execute the following command:
+
+```
+kubectl create namespace aws-kinesis-firehose-event-source
+```
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$kubectl%20create%20namespace%20aws-kinesis-firehose-event-source&completion=New%20project%20creation.
"Opens a new terminal and sends the command above"){.didact})
+
+Now we can set the `aws-kinesis-firehose-event-source` namespace as default
namespace for the following commands:
+
+```
+kubectl config set-context --current
--namespace=aws-kinesis-firehose-event-source
+```
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$kubectl%20config%20set-context%20--current%20--namespace%3Daws-kinesis-firehose-event-source&completion=New%20project%20creation.
"Opens a new terminal and sends the command above"){.didact})
+
+You need to install Camel K in the `aws-kinesis-firehose-event-source`
namespace (or globally in the whole cluster).
+In many settings (e.g. OpenShift, CRC), it's sufficient to execute the
following command to install Camel K:
+
+```
+kamel install
+```
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$kamel%20install&completion=Installing%20Camel%20K.
"Opens a new terminal and sends the command above"){.didact})
+
+NOTE: The `kamel install` command requires some prerequisites to be successful
in some situations, e.g. you need to enable the registry addon on Minikube.
Refer to the [Camel K install
guide](https://camel.apache.org/camel-k/latest/installation/installation.html)
for cluster-specific instructions.
+
+To check that Camel K is installed we'll retrieve the IntegrationPlatform
object from the namespace:
+
+```
+kubectl get integrationplatform
+```
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$kubectl%20get%20integrationplatform&completion=Executed%20Command.
"Opens a new terminal and sends the command above"){.didact})
+
+You should find an IntegrationPlatform in status `Ready`.
+
+You can now proceed to the next section.
+
+## 2. Preparing the environment
+
+This repository contains a simple
[aws-services.properties](didact://?commandId=vscode.openFolder&projectFilePath=04-aws-kinesis-source-basic/aws-services.properties&completion=Opened%20the%aws-services.properties%20file
"Opens the aws-kinesis.properties file"){.didact} that contains the access key
and secret key for accessing the AWS Kinesis stream.
+
+```
+kubectl create secret generic aws-services --from-file=aws-services.properties
+```
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$kubectl%20create%20secret%20generic%20aws-services%20--from-file%3Daws-services.properties&completion=secret%20%22aws-services%22%20created.
"Create a secret with AWS Kinesis credentials"){.didact})
+
+As the example levareges [Knative Eventing
channels](https://knative.dev/v0.15-docs/eventing/channels/), we need to create
the one that the example will use:
+
+```
+kubectl apply -f aws-s3-kinesis-firehose-channel.yaml
+```
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$kubectl%20apply%20-f%20aws-s3-kinesis-firehose-channel.yaml&completion=inmemorychannel.messaging.knative.dev/aws-s3-kinesis-firehose$20created.
"Create a Knative InMemoryChannel named aws-kinesis"){.didact})
+
+
+## 2. Running a Camel Source
+
+This repository contains a simple Camel Source based on the [AWS Kinesis
component](https://camel.apache.org/components/latest/aws-kinesis-component.html)
that forward streaming events received on the AWS Kinesis delivery stream to a
Knative channel named `aws-s3-kinesis-firehose`.
+
+Use the following command to deploy the Camel Source:
+
+```
+kubectl apply -f aws-s3-kinesis-firehose-source.yaml
+```
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$kubectl%20apply%20-f%20aws-s3-kinesis-firehose-source.yaml&completion=camelsource.sources.knative.dev/camel-aws-s3-kinesis-firehose-source%20created.
"Opens a new terminal and sends the command above"){.didact})
+
+## 2. Running a basic integration to create Kinesis events for consumption by
the Camel Source
+
+You need a producer adding data to a Kinesis stream to try this example. This
integration
+comes with a sample producer that will send 100 messages with the text `Hello
Camel K`
+every 3 seconds.
+
+```
+kamel run --secret aws-services aws-kinesis-firehose-producer.groovy
+```
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$kamel%20run%20--secret%20aws-kinesis%20aws-kinesis-firehose-producer.groovy&completion=Camel%20K%20aws-kinesis-firehose-producer%20integration%20run%20in%20dev%20mode.
"Opens a new terminal and sends the command above"){.didact})
+
+If everything is ok, after the build phase finishes, you should see the Camel
integration running.
+
+## 3. Running a basic integration to forward Kinesis events to the console
+
+```
+kamel run aws-s3-consumer.groovy --dev
+```
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$kamel%20run%20aws-s3-consumer.groovy%20--dev&completion=Camel%20K%20aws-s3-consumer%20integration%20run%20in%20dev%20mode.
"Opens a new terminal and sends the command above"){.didact})
+
+If everything is ok, after the build phase finishes, you should see the Camel
integration running.
+
+## 4. Uninstall
+
+To cleanup everything, execute the following command:
+
+```kubectl delete namespace aws-kinesis-firehose-event-source```
+
+([^
execute](didact://?commandId=vscode.didact.sendNamedTerminalAString&text=camelTerm$$kubectl%20delete%20namespace%20aws-kinesis-source-basic&completion=Removed%20the%20namespace%20from%20the%20cluster.
