Internal Hazelcast Developers

If you want to try this tutorial in the UAT or DEV environment, edit the hazelcast.js file to include the following settings:

let createClientConfig = () => {
    return {
        network: {
            ...
            },
            ssl: {
                ...
                sslOptions: {
                    ...
                    // Otherwise the client will throw an error
                    // because the cluster's hostname doesn't match the one
                    // in the self-signed TLS certificate.
                    checkServerIdentity: () => null
                }
            }
        },
        properties: {
            // For DEV, use https://test.dev.hazelcast.cloud
            'hazelcast.client.cloud.url': 'https://uat.hazelcast.cloud',
            ...
        }
    }
};
