🧭 Overview

oapi-cli is a command-line interface for interacting with OUTSCALE APIs. It supports advanced argument syntax, response chaining, JSON file inputs, and a built-in variable system to streamline complex workflows.

The CLI is fully self-contained, with prebuilt packages for Linux (AppImage), macOS (Homebrew), and Windows (zip archive).

---

✅ Requirements

• Outscale API access (AK/SK or login/password)
• Config file or environment variables for authentication
• AppImage support (Linux only, see notes if FUSE is not installed)

---

💻 Installation

macOS

brew tap outscale/tap
brew install outscale/tap/oapi-cli

Or manually:

git clone https://github.com/outscale/homebrew-tap
cd homebrew-tap
brew install Formula/oapi-cli.rb

---

Linux

Download the AppImage from the nightly build.

chmod a+x ./oapi-cli-x86_64.AppImage
./oapi-cli-x86_64.AppImage

Optional installation:

sudo mv oapi-cli-x86_64.AppImage /usr/local/bin/oapi-cli

Note: If you see FUSE-related errors, use:

./oapi-cli-x86_64.AppImage --appimage-extract-and-run ReadImages

---

Windows

Download oapi-cli-x86_64-windows.zip from Releases. Extract and run oapi-cli.exe.

⚠️ Config is read from .\config.json in the current directory.

🚀 Usage

🧾 Command Syntax

oapi-cli <Operation> [OPTIONS]

Get general help:

oapi-cli --help

Get help for a specific operation:

oapi-cli --help DeleteTags

Examples

Complex arguments

oapi-cli DeleteTags --ResourceIds '["ID0", "ID1"]' --Tags '[{"Key": "k0", "Value": "v0"}, {"Key": "k1", "Value": "v1"}]'

Alternative syntax:

oapi-cli --color DeleteTags \
  --ResourceIds[] "ID0" --ResourceIds[] "ID1" \
  --Tags.0.Key k0 --Tags.0.Value v0 \
  --Tags.1.Key k1 --Tags.1.Value v1

Zsh workaround (for brackets):

oapi-cli --color DeleteTags '--ResourceIds[]' "ID0" '--ResourceIds[]' "ID1" ...

Verbose mode:

oapi-cli --verbose ReadVms

Use --file to pass argument from a file:

echo -n false > false.txt
oapi-cli ReadVms --DryRun --file false.txt

CreatePolicy with JSON string

oapi-cli CreatePolicy --PolicyName please \
  --Document --jsonstr-file ./policy.json

---

🧩 Autocompletion

Bash

source <(oapi-cli-x86_64.AppImage --bash-completion)

Or source oapi-cli-completion.bash.

Zsh

autoload bashcompinit
bashcompinit
source ~/oapi-cli-completion.bash

autoload -Uz compinit && compinit  # if not already in .zshrc

---

🔁 Variable System

oapi-cli supports internal variables between chained calls.

oapi-cli CreateVms --ImageId IMG_ID --set-var vm_id=Vms.0.VmId \
  CreateTags --ResourceIds[] --var vm_id --Tags.0.Key Name ..Value "my vm"

This captures the VmId from the first call and reuses it in the second.
