Online Installation

Before starting the installation, make sure the requirements are met.

Create the configuration file

Akamas on Kubernetes is provided as a set of templates packaged in a chart archive managed by Helm.

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:

# 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:

curl -so akamas.yaml  http://helm.akamas.io/templates/1.3.0/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 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:

helm upgrade --install \
  --create-namespace --namespace akamas \
  --repo http://helm.akamas.io/charts \
  --version '1.3.0' \
  -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:

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:

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 /akapi.

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 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.
