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

• SQL Server connection string.

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

• SSL certificate and private key without password

• 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.

• Define TLS secret name. If the SSL certificate is a wildcard certificate then create the tls.onelist secrete for all environments. If a non-wildcard certificate is used then create the tls.onelist.<environment> secret for the targeted environment.

• Download these Yaml files

  • onelist-ingress.yaml

  • onelist-service.yaml

  • onelist-deployment.yaml

  • ingress-nginx-controller.yaml

  • config.yaml

  • ingress-nginx-controller-additional-environment.yaml

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 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

2. Create ConfigMap and Secret

These Kubernetes ConfigMap and Secret contains the required environment variables that are used by OneList services.

...

• 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. 

...

kubectl apply -f config.yaml --namespace <ONELIST_NAMESPACE>

For example: 

kubectl apply -f config.yaml --namespace onelist-dev

3. Create the Secrete for pulling OneList images

Replace placeholders in the command below and run it.

kubectl create secret docker-registry iqx.acr --docker-server=https://iqxbusiness.azurecr.io/ --docker-username=<ACR_USERNAME> --docker-password=<ACR_PASSWORD> --docker-email=<YOUR_EMAIL_ADDRESS> --namespace <ONELIST_NAMESPACE>

For example: kubectl create secret docker-registry iqx.acr --docker-server=https://iqxbusiness.azurecr.io/ --docker-username=acr_username --docker-password=acr_password --docker-email=myemail@example.com --namespace onelist-dev

4. Deploy OneList containers for the apps and services

Run the 2 commands below.

kubectl apply -f onelist-deployment.yaml --namespace <ONELIST_NAMESPACE>

kubectl apply -f onelist-service.yaml --namespace <ONELIST_NAMESPACE>

For example:

kubectl apply -f onelist-deployment.yaml --namespace onelist-dev

kubectl apply -f onelist-service.yaml --namespace onelist-dev

5. Create Nginx ingress service

Follow the instructions in 5.1 to deploy the first OneList environment and the instructions in 5.2 to deploy the additional environments. 

5.1  Deploy the first OneList environment (namespace)

Open the ingress-nginx-controller.yaml file in notepad. 

• Find and replace '<environment>' with the environment label.

• Find and replace '<tls secret name>' with the TLS secret name.

• Save your changes and close the file.

Open onelist-ingress.yaml in notepad.

• Find and replace '<environment>' with the environment label.

• Save your changes and close the file.

Run the 2 commands below.

kubectl apply -f ingress-nginx-controller.yaml

kubectl apply -f onelist-ingress.yaml --namespace <ONELIST_NAMESPACE>

For example:

kubectl apply -f ingress-nginx-controller.yaml

kubectl apply -f onelist-ingress.yaml --namespace onelist-dev

5.2 Deploy additional OneList environment (namespace)

Open the ingress-nginx-controller-additional-environment.yaml file in notepad. 

• Find and replace '<environment>' with the environment label.

• Find and replace '<tls secret name>' with the TLS secret name. 

• Save your changes and close the file.

Open onelist-ingress.yaml in notepad.

• Find and replace '<environment>' with  the name of the environment.

• Save your changes and close the file.

Run the 2 commands below.

kubectl apply -f ingress-nginx-controller-additional-environment.yaml

kubectl apply -f onelist-ingress.yaml --namespace <ONELIST_NAMESPACE>

For example:

kubectl apply -f ingress-nginx-controller-additional-environment.yaml

kubectl apply -f onelist-ingress.yaml --namespace onelist-dev

6. Create the TLS secrete for SSL certificate

Run the command below to create the secret. 

kubectl create secret tls <tls secret name> --cert <SSL_CERTIFICATE_FILE> --key <PRIVATE_KEY_FILE> --namespace ingress-nginx

For example: 

• Wildcard certificate: kubectl create secret tls tls.onelist --cert c:\certificates\certificate.cer --key c:\certificates\certifcate.key --namespace ingress-nginx

• Non-wildcard certificate: kubectl create secret tls tls.onelist.dev --cert c:\certificates\certificate.cer --key c:\certificates\certifcate.key  --namespace ingress-nginx

7. 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 service -n ingress-nginx

8. 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.
