Description

cli-box simplifies the setup of a preconfigured environment for CLI tools. It downloads and installs the necessary tools and dependencies and builds a Docker image, allowing for a consistent environment across different systems.

The script uses a configuration file in YAML format, where you can specify the base image, the tools to install, and their installation commands. The Dockerfile used to build the image is generated dynamically based on the configuration.

Features

• Allows you to manage your CLI tools in a centralized configuration file.

• Ensures consistent environments for your CLI tools across systems.

• Allows easy version control of CLI tools.

• Lets you use the CLI tools without cluttering your system.

• Offers a simple solution using Docker.

Usage

• To access the cli-box, you can run the pre-built Docker images.
• For amd64, x86_64 system:

docker run -it -v $HOME:/root --network host decisivedevops/cli-box:amd64-latest zsh

• For aarch64 , arm64 system:

docker run -it -v $HOME:/root --network host decisivedevops/cli-box:arm64-latest zsh

• To persist the config files for CLI tools, local $HOME directory is mounted as a volume inside the Docker container at /root.
• Also, --network host runs the container on the same network as host.

Here is a list of the current CLI tools available.

Build

Requirements

To build and add your own tools to cli-box, you need to have Docker and yq installed on your system. Here's how to install them: PREREQUISITES

Build Steps

• Clone this repository on your local machine.

git clone https://github.com/decisivedevops/cli-box.git

• cd into the cloned directory.

cd cli-box

• You can update configuration file config.yaml to add tools you require.
• To build cli-box, simply run the script with build command:

./cli-box build

• Once the Docker image is build, the script outputs a command to access the CLI tools.

Refer to USAGE.md file to know how I am using the cli-box along with few other useful tools.

Configuration

cli-box uses a configuration file in YAML format to specify the base image, the tools to install, and their installation commands. Here's an example configuration file:

image_name: decisivedevops/cli-box
base_image: ubuntu:22.04
base_image_build: |
  apt update \
      && apt install -y ncurses-bin

apps:
  kubectl:
    changelog: https://kubernetes.io/releases/patch-releases/
    replacements: "VERSION=1.23.17 AMD64_OS=linux/amd64 ARM64_OS=linux/arm64"
    amd64_url: "https://storage.googleapis.com/kubernetes-release/release/v${VERSION}/bin/${AMD64_OS}/kubectl"
    arm64_url: "https://storage.googleapis.com/kubernetes-release/release/v${VERSION}/bin/${ARM64_OS}/kubectl"
    install: |
      curl -sSL ${URL} -o kubectl \
          && chmod +x kubectl \
          && mv kubectl /usr/local/bin/

Configuration Syntax

• image_name: the name of the Docker image to build.
• base_image: the base image to use for the Docker image.
• base_image_build: the commands to run on the base image before installing the tools.
• apps: a list of tools to install, with their installation commands and URLs for different architectures.
  • replacements: a list of variable replacements to apply to the URLs.
  • <arch>_url: the URL for the tool for a specific architecture.
    • linux/arm64 and linux/amd64 supported
    • This architecture is detected based on the local system's architecture.
      • For example, If you are running this on Apple M series processors, arm64 url is used and for Intel based machines, amd64 url used.
  • install: the installation commands for the tool.

You can add more tools in this configuration file to suit your requirements.
