# Online Installation

Before starting the installation, make sure the [requirements](/akamas-docs/3.4.0/installing/kubernetes/prerequisites.md) are met.

## Create the configuration file

Akamas on Kubernetes is provided as a set of templates packaged in a chart archive managed by [Helm](https://helm.sh/).

To proceed with the installation, you need to create a Helm Values file, called `akamas.yaml` in this guide, containing the mandatory configuration values required to customize your application. The following template contains the minimal set required to install Akamas:

```yaml
# AWS credentials to fetch ECR images (required)
awsAccessKeyId: <AWS_ACCESS_KEY_ID>
awsSecretAccessKey: <AWS_SECRET_ACCESS_KEY>

# Akamas customer name. Must match the value in the license (required)
akamasCustomer: <CUSTOMER_NAME>

# Akamas administrator password. If not set a random password will be generated
akamasAdminPassword: <ADMIN_PASSWORD>

# The URL that will be used to access Akamas, for example 'http://akamas.kube.example.com' (required)
akamasBaseUrl: <INSTANCE_HOSTNAME>
```

You can also download the template file running the following snippet:

```bash
curl -so akamas.yaml  http://helm.akamas.io/templates/1.4.1/akamas.yaml.template
```

Replace in the file the following placeholders:

* `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`: the AWS credentials for pulling the Akamas images
* `CUSTOMER_NAME`: customer name provided with the Akamas license
* `ADMIN_PASSWORD`: initial administrator password
* `INSTANCE_HOSTNAME`: the URL that will be used to expose the Akamas installation, for example `https://akamas.k8s.example.com` when using an Ingress, or `http://localhost:9000` when using port-forwarding. Refer to [Accessing Akamas](/akamas-docs/3.4.0/installing/kubernetes/accessing-akamas.md) for the list of the supported access methods and a reference for any additional configuration required.

## Start the installation

With the configuration file you just created (and the new variables you added to override the defaults), you can start the installation with the following command:

```bash
helm upgrade --install \
  --create-namespace --namespace akamas \
  --repo http://helm.akamas.io/charts \
  --version '1.4.1' \
  -f akamas.yaml \
  akamas akamas
```

This command will create the Akamas resources within the specified namespace. You can define a different namespace by changing the argument `--namespace <your-namespace>`

An example output of a successful installation is the following:

```
Release "akamas" does not exist. Installing it now.
NAME: akamas
LAST DEPLOYED: Thu Sep 21 10:39:01 2023
NAMESPACE: akamas
STATUS: deployed
REVISION: 1
NOTES:
Akamas has been installed

NOTES:
Akamas has been installed

To get the initial password use the following command:

kubectl get secret akamas-admin-credentials -o go-template='{{ .data.password | base64decode }}'
```

## Check the installation

To monitor the application startup, run the command `kubectl get pods`. After a few minutes, the expected output should be similar to the following:

```

users-966f8f78-wv4zj           1/1     Running   0          5m
```

At this point, you should be able to access the Akamas UI using the endpoint specified in the `akamasBaseUrl`, and interact through the Akamas CLI with the path `/api`.

If you haven't already, you can update your configuration file to use a different type of service to expose Akamas' endpoints. To do so, pick from the [Accessing Akamas](/akamas-docs/3.4.0/installing/kubernetes/accessing-akamas.md) the configuration snippet for the service type of your choice, add it to the `akamas.yaml` file, update the `akamasBaseUrl` value, and re-run the installation command to update your Helm release.
