  1 | # Cloudman
  2 | ----------
  3 | Cloudman is a textual user interface (heavily inspired by htop) to manage your Amazon EC2 fleet instantly. By using Cloudman you'll find an overview of your instances, navigate through regions, retrieve instance details, show console outputs and connect to instance terminal using SSM.
  4 | 
  5 | The profiles and defaults as configured in ~/.aws/credentials will be used.

 59 | If you're a **macOS Homebrew** or a **Linuxbrew** user, then you can install
 60 | cloudman from homebrew tap:
 61 | 
 62 | ```bash
 63 | brew install dutchcoders/cloudman/cloudman
 64 | ```
 65 | 
 66 | ### MacPorts
 67 | If you're a **MacPorts** user, you can install Cloudman using:
 68 | 
 69 | ```bash
 70 | sudo port selfupdate
 71 | sudo port install cloudman
 72 | ```
 73 | 
 74 | ## Building
 75 | cloudman is written in Rust, so you'll need to grab a
 76 | [Rust installation](https://www.rust-lang.org/) in order to compile it.
 77 | cloudman compiles with Rust 1.44.0 (stable) or newer. In general, cloudman tracks
 78 | the latest stable release of the Rust compiler.
 79 | 
 80 | To build cloudman:
 81 | 
 82 | ```
 83 | $ git clone https://github.com/dutchcoders/cloudman
 84 | $ cd cloudman
 85 | $ cargo build --release
 86 | $ ./target/release/cloudman --version
 87 | 0.1.0
 88 | ```
 89 | 
 90 | ## Current features
 91 | * overview of all instances
 92 | * support different profiles
 93 | * switch easily between aws regions
 94 | * connect using SSM to instance (using tmux)
 95 | * search through instances
 96 | * filter instances
 97 | * show detailed information for instances
 98 | * show console output if supported
 99 | 
100 | # Roadmap
101 | * start and stop instances (actions)
102 | * request spot instances
103 | * modifyable columns
104 | * sorting
105 | * show filter active
106 | * show indicator of loading
107 | * search through console output
108 | * much more
109 |
