CircleCI CLI is your command-line companion for interacting with CircleCI, offering a wide array of functionalities for developers. Whether you’re looking to install, configure, or validate your build configurations, this guide will get you up to speed!

Installation

Certainly, you can install the CircleCI CLI using various package managers or through an installation script. Let’s explore both methods:

Using Package Managers

• Homebrew: For macOS users, simply execute the following command:

brew install circleci

• Snap: For Linux interactions, run:

sudo snap install circleci

• Chocolatey: Windows enthusiasts can install via:

choco install circleci-cli -y

Using the Install Script

If you’d prefer to use a script for installation, you can do so on most Unix platforms. Run:

curl -fLSs https://raw.githubusercontent.com/CircleCI-Public/circleci-cli/main/install.sh | bash

By default, this command installs the CircleCI app to the /usr/local/bin directory. If you don’t have write permissions, add sudo:

curl -fLSs https://raw.githubusercontent.com/CircleCI-Public/circleci-cli/main/install.sh | sudo bash

You can also specify an alternate install location or a particular version by defining environment variables in the command.

Configuration

Once installed, you need to configure the CLI:

$ circleci setup

You’ll be prompted to enter your CircleCI API Token, which you can find in the Personal API Token tab.

Validating Your Build Configuration

To ensure everything is in order, you can validate your build config file:

$ circleci config validate

If your configuration file (.circleci/config.yml) is valid, you’ll see confirmation on the command line.

Using Docker

You can also run the CircleCI CLI without installation via Docker:

docker run --rm -v $(pwd):data -w data circleci/circleci-cli:alpine config validate data/.circleci/config.yml --token $TOKEN

Troubleshooting

If you encounter issues:

• Ensure you have the correct permissions if using the install script.
• Double-check your API token for configuration to ensure it’s set up correctly.
• If commands aren’t recognized, try rechecking your PATH variable for CircleCI binaries.
