IWF Deployment Procedure

The following procedure guides you through installation of OCIWF on CNE.

Table 5-1 OCIWF Deployment

Step # Procedure Description

1

img/icon.png 		Create Database User/Group

Create User with permission to access the tables on all the SQL nodes present in the NDB cluster, by executing:

Note:

  • The OCIWF uses a MySQL database to store the configuration and run time data.
  • The OCIWF deployment using MySQL NDB cluster requires the database administrator to create user in MYSQL DB and to provide the user with necessary permissions to access the tables in the NDB cluster.
  1. Login to the server where the ssh keys are stored and SQL nodes are accessible.
  2. Connect to the SQL nodes.

    ssh <USERNAME>@<HOSTNAME>

  3. Login to the MYSQL as a root user:

    /usr/local/mysql/bin/mysql -h 127.0.0.1 -u root -p <password>

  4. Create MYSQL user: 
    
CREATE USER '<USERNAME>'@'%' IDENTIFIED BY '<PASSWORD>';
DROP DATABASE if exists diameter;
CREATE DATABASE diameter CHARACTER SET utf8;
GRANT SELECT, INSERT, CREATE, ALTER, DROP, LOCK TABLES,
CREATE TEMPORARY TABLES, DELETE, UPDATE, EXECUTE ON diameter.* TO
'<USERNAME>'@'%';
  5. Execute the following commands on one of the NDB SQL node:
    1. Log into the MYSQL user created in the previous step:

      /usr/local/mysql/bin/mysql -h 127.0.0.1 -u <USERNAME> -p <PASSWORD>

    2. Create MYSQL table: 
      USE diameter;
CREATE TABLE IF NOT EXISTS SESSION_CORRELATION (
 SESSION_ID varchar(255) NOT NULL,
 RESOURCE_ID varchar(255) NOT NULL UNIQUE,
 PEER_IDENTITY varchar(255) NOT NULL,
 PEER_REALM varchar(255) NOT NULL,
 REQUEST_COUNT int(11),
 PRIMARY KEY (SESSION_ID)
) ENGINE=NDBCLUSTER DEFAULT CHARSET=utf8;

    Note: The <username> and <password> is created by the Database Administrator.

  6. Exit from database and logout from SQL node.

Customize ociwf-custom-values.yaml file as per the deployment requirement:

Update service ports accordingly.

For more information, see IWF Installation Preparation.

To configure the parameters, see section IWF Configuration

or,

The ociwf-custom-values-1.4.0.yaml template can be downloaded from OHC.

Download the InterWorking and Mediation Function (IWF) Custom Template ZIP file and Unzip to get ociwf-custom-values-1.4.0.yaml file.

img/icon.png 		Perform the Diameter configuration Configure diameter peer(s) in the following file:

ociwf/charts/pcf/templates/configmap-pcf-diam-gateway-service-diameter.yaml

Refer, IWF User guide for diameter peer configuration details.

4

img/icon.png 		Deploy IWF from Helm repository To deploy IWF from helm repository, execute:

helm install ociwf/ -f <ociwf-custom-values.yaml> --name <helm-release> --namespace <k8s namespace> --version <ociwf version>

For example:

helm install ociwf-helm-repo/ociwf -f ociwf-custom-values.yaml --name ociwf --namespace iwfsvc --version <ociwf version>

or,

5

img/icon.png 		Deploy IWF from local repository To deploy IWF from local repository, execute:

helm install ociwf -f <ociwf-custom-values.yaml> --name <helm-release> --namespace <k8s namespace>

For example:

helm install ociwf -f ociwf-custom-values.yaml --name ociwf --namespace iwfsvc

6

img/icon.png 		Check status of the services Execute the following command:

kubectl get services -n <namespace>

For example:

kubectl get services -n iwfsvc

Note: If metallb is used, EXTERNAL-IP is assigned to ociwf-endpoint.

7

img/icon.png 		Check status of the pods Execute the following command:

kubectl get pods -n <ociwf_namespace>

Status column of all the pods should be 'Running'.

Ready column of all the pods should be n/n, where n is number of containers in the pod.

For example:

kubectl get pods -n iwfsvc
