As a Bluemix developer you typically need to use several CLIs (command line interfaces). There is a specific CLI for Bluemix with multiple plugins to manage Bluemix applications and services. Additionally you can use third party CLIs like Docker, Kubernetes and Cloud Foundry against Bluemix.
Recently a new tool has been published for macOS ‘IBM Cloud Application Tools 2‘ (beta). I find this tool pretty useful since you can install and update all CLIs with a few clicks. In the past I had to download new CLI versions manually, find the right install locations, set environment paths, etc.
Here is a screenshot.
If you don’t use macOS you might be interested in a Docker image with all CLIs which my colleague Ansgar published.
