Codefresh Compose Model

Codefresh introducing CF-Compose-Model, our model for all compositions. Using our compose model you can:

• Verify that your composition is valid on Codefresh.io

• Convert Composition from one type to another

Example

More examples can be found here:

• node example.js to run the basic examples we provided

'use strict';

const Promise      = require('bluebird');
const path         = require('path');
const CM           = require('cf-compose-model');
const ComposeModel = CM.ComposeModel;

    const path = './lib/model/tests/ComposeV1/ex1.yaml';

    console.log(`\n#############################\nExample load yaml from location ${locapathtion}\n#############################`);

    let location = path.resolve(__dirname, path);
    return ComposeModel.load(location)
        .then(compose => {
            return compose.getWarnings();
        })
        .then((warnings) => {
            console.log('\n===\nWarnings\n===');
            return Promise.map(warnings, (warning) => {
                console.log(warning.format());
            });

        })
        .then(() => {
            return cm.translate().toYaml();
        })
        .then((translated) => {
            console.log('\n===\nOutput\n===');
            console.log(translated);
        });

Documantation

Become familiar with ComposeModel structure

ComposeModel holds inside 3 basic objects - each one of the objects holds in instances of CFNode class:

• services
• networks
• volumes

More objects that ComposeModel holds:

• originalYaml - the yaml file ComposeModel parsed. Optional
• parser - the original parser class that used to parse the yaml. Optional
• defaultTranslator - the translator that will be used if no other translator will be passed in translate method. The defaultTranslator exist only if the ComposeModel parsed some yaml and a translator exist for it.
• policy - set of instructions that tell ComposeModel what are to possible warnings may each CFNode and CFLeaf have. The default value is the policy of the shared plan.

Methods of ComposeModel:

• static:
  • parse(yaml) - Parse an yaml, search for a parser for the yaml file, parse it and return ComposeModel instance. Throw an error `parser not found' if there is no parser.
  • load(path) - Loads the yaml and parse it the same way the parse does.
• public:
  • getAllServices() - return an object with all the services
  • getAllNetworks() - return an object with all the networks
  • getAllVolumes() - return an object with all the volumes
  • setPolicy(policy) - set the policy. Policies can be found in lib/model/policies.
  • addService(service) - add new service to the model
  • addNetwork(network) - add new network to the model
  • addVolume(volume) - add new volume to the model
  • translate(translator) - translate the model to yaml file, if translator not supplied the model will try to use the default translator if exist.
  • getWarnings() - return an array with all the warnings related to the model and the policy
  • fixWarnings(onlyAutoFix) - fix all the warnings on the model related to the policy. If onlyAutoFix flag is set then only warnings with this flag will be fixed.
