Prerequisites

• Install Kubernetes CLI tool - kubectl. Instructions can be found here: https://kubernetes.io/docs/tasks/tools/install-kubectl/

• Install the command-line tool of the Kubernetes hosting system:

  • Azure (AKS) https://docs.microsoft.com/en-us/cli/azure/install-azure-cli-windows?view=azure-cli-latest

• Install Helm package manager

  • https://helm.sh/docs/intro/install/

• SQL Server connection string.

  • The SQL connection user account must have permission to create new databases and db_owner of the databases.

• SSL certificate with all intermediate certificates in PFX or PEM format

• Request the container registry login from IQX for pulling OneList images

• SMTP server login and email address if email approval channel is enabled

• Generate the Machine key for each environment. This is a Base64 string representing an array of 50 bytes.

  • Use tools like https://generate.plus/en/base64  to generate a random string of the required length.

• Define the Kubernetes namespace for the OneList environment to be deployed. E.g. onelist-dev, onelist-qa, onelist-prod. It may be required to follow your company's naming standard for these namespaces.

  • Use this value to  replace the <ONELIST_NAMESPACE> placeholder in the instructions below.

• Define the label for the OneList environment to be deployed. This is a short label, e.g. dev, qa, prod. The first letter must be unique in all the environments planned and it is used as the suffix of the database names.

  • Use this value to replace the <environment> placeholder in the instructions below.

• Download the below two files and put them in the same directory

Recommended Configuration

Log on to Azure Kubernetes Service (AKS)

1. Log on to Azure by executing this command: az login
   Tip: Specify the tenant if there are multiple tenants. E.g. az login --tenant <tenant>

2. Setup the Azure log in with kubectl by executing this command: az aks get-credentials --resource-group <Azure_Resource_Group> --name <AKS_Cluster_Name>

Deployment steps

Open a command prompt from the folder that contains the YAML deployment files. Flow steps below to deploy OneList.

1. Create Kubernetes cluster and Application gateway

Follow this documentation to create a new AKS cluster with the AGIC add-on enabled.

https://docs.microsoft.com/en-us/azure/application-gateway/tutorial-ingress-controller-add-on-new#deploy-an-aks-cluster-with-the-add-on-enabled

2. Create the Kubernetes namespace

Run the command below to create the Kubernetes namespace for the OneList environment, e.g. onelist-dev.

kubectl create namespace <ONELIST_NAMESPACE>

For example: 

kubectl create namespace onelist-dev

3. Edit values.yaml file

The values.yaml file configures the required environment variables that are used by OneList services.

Open the "values.yaml" in notepad and update the following fields with the actual value. 

• Config

  • RoleManager__MachineKey 
    The value is the generated machine key.

  • Database__ConnectionString
    The value is the SQL Server connection string. The name of the databases will be automatically specified by the services.

  • ASPNETCORE_ENVIRONMENT
    The value is <environment>.

  • Smtp__UserName 

  • Smtp__Password

  • Smtp__From
    This is the sender email address of notifications from OneList

  • Smtp__Host
    This is the SMTP server OneList use to send notifications.

  • Smtp__Port
    This is the port of SMTP server.

  • Smtp__UseSsl
    Define if SMTP server uses SSL connection. For Office365 SMTP service, the value is always false. 

  • RootUrl
    Root URL of the OneList site.

  • Localization__DefaultCulture
    The default culture. Use the code from: Supported Languages

  • Localization__DefaultTimeZone
    The default time zone. The time zone id is the “TZ database name” from this page: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones

  • supportedCultures

    • Localization__SupportedCultures__0
      The other supported cultures. Use the code from: Supported Languages. When there is more than one supported culture, add another Localization__SupportedCultures__n entry and increase the trailing number n by 1. E.g. Localization__SupportedCultures__1

• imageCredentials

  • username
    Login username of IQX container registry.

  • password
    Login password of IQX container registry.

  • email
    Your email address.

• ingress

  • host
    The DNS host name of the OneList application.

• image

  • tag
    Tag name of the images that are going to be deployed.

Save the "values.yaml" file.

4. Deploy OneList Helm chart

Enter the folder that contains the values.yaml and onelist.tgz files. Run the command below.

helm install <ONELIST_NAMESPACE> -n <ONELIST_NAMESPACE> -f .\values.yaml onelist.tgz

For example:

helm install onelist-dev -n onelist-dev -f .\values.yaml onelist.tgz

5. Configure SSL connection

Follow step 1 to 4 in this document. Migrate to use Azure Key Vault to host SSL certificate

6. Get the OneList public IP address

Run the following command to discover the public IP address for the environment so that DNS can be created and bound to this IP address.

kubectl get ingress -n <ONELIST_NAMESPACE>

7. Create the administrator user account

• Navigate to the OneList URL in the browser, you will be presented to the following page to create the first user account. The System Administrator access is automatically granted to this user account.

• Log on using the email and password of the newly created user account to complete the application configuration steps.
