Registering and Running in Connected Mode with a Connected App | MuleSoft Documentation
# Registering and Running in Connected Mode with a Connected App  
## Before You Begin
Before registering Flex Gateway, you must complete the following tasks:
  * Configure a Connected App
    * Include the following scopes:
      * Read Servers
      * Manage Servers
      * View Organization
    * Save the **Id** and **Secret** of the Connected app you configure.
  * Install a Flex Gateway
  * Request _Manage Servers_ and _Read Servers_ permissions in Runtime Manager from your Anypoint Platform admin
  * Collect the following information from your Anypoint Platform instance:
    * The **Organization ID** for the organization where you want to run Flex Gateway
See Find your Organization ID for more information on how to find your Organization ID.
    * The **Environment ID** for the environment where you want to run Flex Gateway
See What API Manager Looks Like for more information on how to find your Environment ID.


## Register and Run with a Connected App as a Linux Service
Flex Gateway runs on the following Long Term Support (LTS) versions of Linux:
  * Amazon Linux 2023
  * CentOS 8
  * Debian Bookworm
  * Red Hat Enterprise Linux (9)
  * Red Hat Enterprise Linux (9) on IBM Power (ppc64le)
  * Ubuntu Jammy


To register a Flex Gateway with Anypoint Platform, you must enter the registration command and then the start command. Each command includes information specific to your Anypoint Platform instance and **must be updated before** executing. See Before You Begin for more information on how to find the information you will need.
  * `--client-id` = the Id for the Connected App you configured in Access Management
  * `--client-secret` = the Secret for the Connected App you configured in Access Management
  * `--environment` = the Environment Id for the environment in Anypoint Platform where you want the Flex Gateway to run
  * `--organization` = your Organization ID in Anypoint Platform
  * `--split` (optional) = the flag that determines whether registration information should split into multiple files. The default value is `false`.
If `split` is set to `true`, registration information is split into two files: `registration.yaml` and `certificate.yaml`. If `false`, all registration information is contained in one file: `registration.yaml`.
  * `--output-directory` (optional) = the directory in which registration information is output
  * `my-gateway` = the name you want to assign the gateway cluster


### Register Flex Gateway
Register your Flex Gateway instance using the data that you gathered for the command options.
```
flexctl registration create \
--client-id=<your-connected-app-client-id> \
--client-secret=<your-connected-app-client-secret> \
--environment=<your-environment-id> \
--connected=true \
--organization=<your-org-id> \
--output-directory=/usr/local/share/mulesoft/flex-gateway/conf.d \
my-gateway
```

Use `sudo` if you encounter file permission issues when running this command.
If you are in Europe you will need to add the `--anypoint-url=https://eu1.anypoint.mulesoft.com` flag to your command.   
---  
In the output directory, you should see the following new registration file(s):
  * `registration.yaml`
  * `certificate.yaml` (generated only if the `split` registration parameter is set to `true`, otherwise certificate information will be contained in `registration.yaml`)


These generated files are credentials for you to connect your Flex Gateway. If you lose them you can no longer connect your Flex Gateway.   
---  
In Runtime Manager, click **← Flex Gateway** in the left navigation to find your gateway in the UI. Notice that your gateway’s status is **Not Running**. Refresh the page, if necessary.
### Start Commands
Start Flex Gateway with the following command:
```
sudo systemctl start flex-gateway
```

Verify that the Flex Gateway service is running successfully:
```
systemctl list-units flex-gateway*
```

If `flex-gateway.service` has a status of `active`, Flex Gateway is successfully running.
```
 UNIT               LOAD  ACTIVE SUB   DESCRIPTION
 flex-gateway.service       loaded active running Application
```

In Runtime Manager, click **← Flex Gateway** in the left navigation to find your new gateway in the UI. Notice that your gateway’s current status is **Running**. Refresh the page, if necessary.
After 30 days, a stopped or deleted gateway is removed from the Runtime Manager UI. Otherwise, the UI continues to list the gateway even if it is no longer running or connected.   
---

## Register and Run with a Connected App in a Kubernetes Cluster
Register Flex Gateway, and then use Helm to deploy Flex Gateway to a node in your cluster and connect to Anypoint Platform. After deploying, use Runtime Manager to verify that the gateway is present and connected to Anypoint Platform.
When deploying Flex Gateway to a Kubernetes cluster that enables role-based access control (RBAC), you must have cluster-level permissions to permit installation of custom resource definitions (CRDs) used by Flex Gateway.
Complete the following steps:
  1. Collect Your Registration Data
  2. Register Flex Gateway
  3. Install Helm Chart into the Namespace


In Connected Mode, Flex Gateway typically serves as an ingress or Edge API gateway that receives traffic from outside of the cluster. Flex Gateway can also act as a standalone gateway for internal (east-west) services.
Most management takes place within Anypoint Platform:
  * Deploy APIs to your cluster.
  * Apply policies and other configurations.
  * Create resources (_with the exception_ of Configuration and Service resources).


In Connected Mode, resource creation through `kubectl apply` is possible but restricted to the following resource types: Configuration, Service, Extension, and PolicyBinding of types `tls`, `tls-inbound`, and `tls-outbound`. For more info about resources, see Declarative Configuration Reference Guide.
### Collect Your Registration Data
Before registering your Flex Gateway instance, collect information for the following registration command options:
  * `--client-id` = the Id for the Connected App you configured in Access Management
  * `--client-secret` = the Secret for the Connected App you configured in Access Management
  * `--environment` = the Environment Id for the environment in Anypoint Platform where you want the Flex Gateway to run
  * `--organization` = your Organization ID in Anypoint Platform
  * `--split` (optional) = the flag that determines whether registration information should split into multiple files. The default value is `false`.
If `split` is set to `true`, registration information is split into two files: `registration.yaml` and `certificate.yaml`. If `false`, all registration information is contained in one file: `registration.yaml`.
  * `--output-directory` (optional) = the directory in which registration information is output
  * `my-gateway` = the name you want to assign the gateway cluster


### Register Flex Gateway
Register your Flex Gateway instance using the data that you gathered for the command options.
You can register using one of the following container runtimes:
Run the following command to register using Docker:
```
docker run --entrypoint flexctl \
-v "$(pwd)":/registration -u $UID mulesoft/flex-gateway \
registration create \
--client-id=<your-connected-app-client-id> \
--client-secret=<your-connected-app-client-secret> \
--environment=<your-environment-id> \
--connected=true \
--organization=<your-org-id> \
--output-directory=/registration \
my-gateway
```

Use `sudo` if you encounter file permission issues when running this command.
If you are in Europe you will need to add the `--anypoint-url=https://eu1.anypoint.mulesoft.com` flag to your command.   
---  
In the output directory, you should see the following new registration file(s):

### Install Helm Chart into the Namespace
A Helm chart installs Flex Gateway, monitoring tools, and applications. A minimum Helm version of 3.0.0 is required. Refer to Helm Chart Settings for configuration options.
  1. Add a Helm repository named `flex-gateway` for your chart:
```
helm repo add flex-gateway https://flex-packages.anypoint.mulesoft.com/helm
```

The command either adds the repository or skips this process if a Helm repository with that name already exists on your machine:
     * If the repository is new, the command returns the following message:
```
"flex-gateway" has been added to your repositories
```

     * If the repository already exists, the command returns the following message:
```
"flex-gateway" already exists with the same configuration, skipping
```

  2. Run `helm repo up`.
The command returns the following message:
```
Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "flex-gateway" chart repository
Update Complete. ⎈Happy Helming!⎈
```

If you have more than one Helm repository on your machine, the message in your terminal window lists all of the repositories.
  3. Run the Helm command for deploying your gateway in Connected Mode:
```
helm -n gateway upgrade -i --create-namespace \
ingress flex-gateway/flex-gateway \
--set gateway.mode=connected \
--set-file registration.content=registration.yaml
```

This command creates the `gateway` namespace and a release named `ingress` if they do not exist. You can use names of your choice for your namespace and release. The command syntax for the Helm repository and chart names is `<helm-repo-name>/<helm-chart-name>`.
The command uses `--set gateway.mode=connected` because the default for the Helm chart is Local Mode.
When you install Flex Gateway, a Service type `LoadBalancer` is created by default. You must have the appropriate permissions to create a load balancer in your cloud. If the load balancer is not provisioned or has issues with the provisioning process, you must choose another type by changing the `service.type` property during the installation.
By default, Flex Gateways running in Kubernetes or Openshift use a readiness probe. If there’s no API deployed to your Flex Gateway instance, the readiness state is `false`. This isn’t an issue with custom readiness probe configurations.   
---  
When successful, the command prints a message indicating an upgrade to your `ingress` release:
```
Release "ingress" does not exist. Installing it now.
NAME: ingress
LAST DEPLOYED: Mon Mar 20 21:36:19 2023
NAMESPACE: gateway
STATUS: deployed
REVISION: 1
TEST SUITE: None
```

The `REVISION` value increments the `ingress` release by `1` each time you run this command with the same namespace, repository, and chart names. For example, if you run the command a second time, you find a new revision number (`REVISION: 2`). The `LAST DEPLOYED` date reflects the date of that revision.


In Runtime Manager, click **← Flex Gateway** in the left navigation to find your new gateway in the UI. Notice that your gateway’s current status is **Running**. Refresh the page, if necessary.
After 30 days, a stopped or deleted gateway is removed from the Runtime Manager UI. Otherwise, the UI continues to list the gateway even if it is no longer running or connected.   
---  
### Helm Chart Settings
To modify the default Helm settings with new values, such as `resource` values for CPU and memory settings, see Update Pod Settings for a Flex Gateway Deployment Through a Helm Chart. For additional Helm chart configurations, see Managing Kubernetes Deployments.
Before modifying a Helm chart for a Flex Gateway deployment, review the default Helm chart settings:
  * Open the **flex-gateway** page in ArtifactHUB
  * Run `helm show values <repository-name>/<chart-name>` from a terminal window.
Example:
```
helm show values flex-gateway/flex-gateway
```

The example returns _default_ values of a repository and chart with the same name.


To view the Helm chart `README`, run `helm show readme <repository-name>/<chart-name>` from a terminal window.
Example:
```
helm show readme flex-gateway/flex-gateway
```

## Register and Run with a Connected App in an OpenShift Cluster
Register Flex Gateway, and then use Helm to deploy Flex Gateway to a node in your cluster and connect to Anypoint Platform. After deploying, use Runtime Manager to verify that the gateway is present and connected to Anypoint Platform.
When deploying Flex Gateway to a Kubernetes cluster that enables role-based access control (RBAC), you must have cluster-level permissions to permit installation of custom resource definitions (CRDs) used by Flex Gateway. In OpenShift, the `cluster-admin` role provides this level of access.
From the command line, OpenShift procedures match Kubernetes procedures. Complete the following steps:
  1. Collect Your Registration Data
  2. Register Flex Gateway
  3. Install Helm Chart into the Namespace

When successful, the command prints a message indicating an upgrade to your `ingress` release:
```
Release "ingress" does not exist. Installing it now.
NAME: ingress
LAST DEPLOYED: Mon Mar 20 21:36:19 2023
NAMESPACE: gateway
STATUS: deployed
REVISION: 1
TEST SUITE: None
```

The `REVISION` value increments the `ingress` release by `1` each time you run this command with the same namespace, repository, and chart names. For example, if you run the command a second time, you find a new revision number (`REVISION: 2`). The `LAST DEPLOYED` date reflects the date of that revision.


In Runtime Manager, click **← Flex Gateway** in the left navigation to find your new gateway in the UI. Notice that your gateway’s current status is **Running**. Refresh the page, if necessary.
After 30 days, a stopped or deleted gateway is removed from the Runtime Manager UI. Otherwise, the UI continues to list the gateway even if it is no longer running or connected.

### Helm Chart Settings
To modify the default Helm settings with new values, such as `resource` values for CPU and memory settings, see Update Pod Settings for a Flex Gateway Deployment Through a Helm Chart. For additional Helm chart configurations, see Managing Kubernetes Deployments.
Before modifying a Helm chart for a Flex Gateway deployment, review the default Helm chart settings:
  * Open the **flex-gateway** page in ArtifactHUB
  * Run `helm show values <repository-name>/<chart-name>` from a terminal window.
Example:
```
helm show values flex-gateway/flex-gateway
```

The example returns _default_ values of a repository and chart with the same name.


To view the Helm chart `README`, run `helm show readme <repository-name>/<chart-name>` from a terminal window.
Example:
```
helm show readme flex-gateway/flex-gateway
```
