Install Redocly CLI

Choose the most appropriate installation method for your needs:

Install globally


Make sure you have the newest version of npm/yarn before you begin.

npm i -g @redocly/cli@latest

Running redocly --version confirms that the installation was successful, and the currently-installed version of the tool.

Use npx at runtime

npx is npm's package runner. It installs and runs a command without installing it globally. You might use this where you can't install a new command, or in a CI context where the command is only used a handful of times.

npx @redocly/cli <command> [options]

Run commands inside Docker

Redocly CLI is available as a pre-built Docker image in Docker Hub and GitHub Packages.

Install Docker if you don't have it already, then pull the image with the following command:

docker pull redocly/cli

To give a Docker container access to your OpenAPI description files, you need to mount the containing directory as a volume. Assuming the API description is in the current working directory, the command to use is:

docker run --rm -v $PWD:/spec redocly/cli lint openapi.yaml

Run CLI behind a proxy

If you need to run the CLI tool behind a proxy, you can use the HTTP_PROXY and HTTPS_PROXY environment variables to configure the proxy settings. These environment variables are commonly used to specify the proxy server for HTTP and HTTPS traffic, respectively.

Set up Proxy Environment Variables

Before running the CLI behind a proxy, make sure to set the appropriate proxy environment variables. Open a terminal and use the following commands:

# For HTTP proxy
export HTTP_PROXY=http://your-http-proxy-server:port

# For HTTPS proxy
export HTTPS_PROXY=https://your-https-proxy-server:port

Use Environment Variables with CLI Commands

You can also directly include the proxy environment variables in the command itself. For example:

HTTPS_PROXY=https://your-https-proxy-server:port redocly lint --extends minimal openapi.yaml
