IBP Console Versions

This is a simple usage of the IBP Console API to determine the versions of the Fabric component, (Peers, Orderers, CAs etc.) that can be used in Ansible scripts.

Running the tool

The following command line arguments are set up

Options:
      --help     Show help                                             [boolean]
      --version  Show version number                                   [boolean]
  -y, --yml      output the latest in yaml format
  -n, --nossl    disable the ssl check for self-signed certs
  -c, --cfg      path to yml to use for auth

Environment variables

You will need to have an IBP Console Service Credential and API Endpoint. You might also need the token endpoint if not using the 'test.cloud.ibm.com' instance. Create a .env file like this; this will be read automatically by the code.

IBP_KEY=<apikey>
IBP_ENDPOINT=<api_endpoint>
API_TOKEN_ENDPOINT=https://iam.test.cloud.ibm.com/identity/token

Alternatively, they can be specified in a yaml file the name given as a command line argument. (this is so you can share the configuration with Ansible playbooks)

./ibp_hlf_version.js

IBP APIs Used

The step is to authenticate and create a client to connect to the IBP Console. Depending on how the IBP Console is installed (is it a public IBM cloud SaaS instance, or has it been installed from the docker images) will determine the authentication method.

// the API key, and endpoint need to used here. Get these from a IBP Service Credential
// Create an authenticator
let authenticator;
if (authtype === 'ibmcloud') {
    authenticator = new ibp.IamAuthenticator({
        apikey: apikey,
        url: ibpendpoint
    });
} else {
    authenticator = new BasicAuthenticator({
        username: apikey,
        password: apisecret,
    });
}

This authenticator is then used to create the client to the IBP Console

// Create client from the "BlockchainV3" class
const client = ibp.BlockchainV3.newInstance({
    authenticator,
    url: ibpendpoint,
    disableSslVerification: args.nossl
});

To get the versions of components, the API call is simply

response = await client.getFabVersions();

Most of the code in the file is related to handling the output and formatting.
