Olares CLI

This directory contains the code for olares-cli, the official command-line interface for administering an Olares cluster. It provides a modular, pipeline-based architecture for orchestrating complex system operations. See the full Olares CLI Documentation for command reference and tutorials.

Key responsibilities include:

• Cluster management: Installing, upgrading, restarting, and maintaining an Olares cluster.
• Node management: Adding to or removing nodes from an Olares cluster.

Execution Model

For most of the commands, olares-cli is executed through a four-tier hierarchy:

Pipeline ➜ Module ➜ Task ➜ Action

Example: install-olares Pipeline

Pipeline: Install Olares
├── ...other modules
└── Module: Bootstrap OS
    ├── ...other tasks
    ├── Task: Check Prerequisites
    │   └── Action: run-precheck.sh
    └── Task: Configure System
        └── Action: apply-sysctl

Build from source

Prerequisites

• Go 1.24+
• GoReleaser (optional, for cross-compiling and packaging)

Sample commands

# Clone the repo and enter the CLI folder
cd cli

# 1) Build for the host OS/ARCH
go build -o olares-cli ./cmd/main.go

# 2) Cross-compile for Linux amd64 (from macOS, for example)
GOOS=linux GOARCH=amd64 go build -o olares-cli ./cmd/main.go

# 3) Produce multi-platform artifacts (tar.gz, checksums, etc.)
goreleaser release --snapshot --clean

Development workflow

Add a new command

1. Create the command file in cmd/ctl/<category>/.
2. Define a pipeline in pkg/pipelines/.
3. Implement modules & tasks inside the relevant pkg/ sub-packages.

Test your build

1. Upload the self-built olares-cli binary to a machine that's running Olares.
2. Replace the existing olares-cli binary on the machine using sudo cp -f olares-cli /usr/local/bin.
3. Execute arbitrary commands using olares-cli
