CF HTML5 Applications Repository CLI Plugin

https://sap.github.io/cf-html5-apps-repo-cli-plugin

Description

The CF HTML5 Applications Repository CLI Plugin is a plugin for the Cloud Foundry CLI tool that aims to provide easy command line access to APIs exposed by the HTML5 Application Repository service. It allows you to:

• Inspect HTML5 applications of current space
• List files of a specific HTML5 application
• View HTML5 applications exposed by business services that are bound to the Approuter application
• Download a single file, application or the whole bucket of applications uploaded with the same service instance of the html5-apps-repo service
• Push one or multiple applications using existing service instances of app-host plan, or create new ones for you on-the-fly

CF HTML5 Applications Repository CLI Plugin is licensed under the Apache License, Version 2.0 - see LICENSE. It also contains third-party open source modules. Third-party module license information is available in machine-readable format in the .reuse/dep5 file.

Configuration

The configuration of the CF HTML5 Applications Repository CLI Plugin is done by using environment variables. The following are supported:

• DEBUG=1 - enables trace logs with detailed information about currently running steps. If you want to see also the sensitive information in the trace logs (e.g. access tokens), use DEBUG=2 instead. To see the raw HTTP responses in trace logs, use DEBUG=3.
• HTML5_CACHE=1 - enables persisted cache. Disabled by default. Should be enabled only for sequential execution of the CF HTML5 Applications Repository CLI Plugin commands in the same context (org/space/user) during short period of time (less than 12 hours)
• HTML5_SERVICE_NAME - name of the service in CF marketplace (default: html5-apps-repo)
• HTML5_RUNTIME_URL - URL of HTML5 runtime to serve business service destinations (default: https://<tenant>.cpp.<landscape_url>)
• HTML5_APP_RUNTIME_KEY_PARAMETERS - JSON string with parameters to be used, when service key of html5-apps-repo service app-runtime plan is created. E.g. to force creation of x509 credentials:

  HTML5_APP_RUNTIME_KEY_PARAMETERS='{"xsuaa":{"credential-type":"x509","x509":{"key-length":2048,"validity":7,"validity-type":"DAYS"}}}'
  

In addition CF HTML5 Applications Repository CLI Plugin supports the following configuration of Cloud Foundry CLI itself:

• --skip-ssl-validation - command line argument option of cf login
• SSL_CERT_FILE - environment variable pointing to file with additional signing certificate
• SSL_CERT_DIR - environment variable pointing to directory with server.crt file containing additional signing certificate As an alternative, you can (install)[https://docs.cloudfoundry.org/cf-cli/self-signed.html] custom or self-signed certificate on machine, where CLI is running.

Troubleshooting

Services and Service Keys

In order to work with HTML5 Application Repository API, the CF HTML5 Applications Repository CLI Plugin is required to send JWT with every request. To obtain it, the CF HTML5 Applications Repository CLI Plugin creates temporary artifacts, such as service instances of html5-apps-repo service and service keys for these service instances. If one of the flows invoked by the CF HTML5 Applications Repository CLI Plugin fails in the middle, these artifacts may remain in the current space.

Self-signed Certificates

Note, that on macOS Cloud Foundry CLI itself (does not support)[https://github.com/cloudfoundry/cli/issues/1263] the SSL_CERT_FILE and SSL_CERT_DIR. Therefore, running the CLI commands is only possible if at least one of two conditions is met:

• The login was done with cf login --skip-ssl-validation, and all subsequent CLI commands ignore certificate issues
• The certificate of Cloud Foundry deployment was installed on machine, where CLI is running

Trying to use both --skip-ssl-validation and SSL_CERT_FILE will result in commands, targeting Cloud Foundry Cloud Controller, executed without certificate validation, and commands targeting services (e.g. HTML5 Applications Repository) will check server certificate using SSL_CERT_FILE.

Limitations

Currently, you can't use the CF HTML5 Applications Repository CLI Plugin with global -v flag due to limitations of cf curl that is used internally by the plugin.

How to obtain support

If you need any support, have any question or have found a bug, please report it in the GitHub bug tracking system. We shall get back to you.
