up - The Upbound CLI

up is the official CLI for interacting with Upbound Cloud, Upbound Enterprise, and Universal Crossplane (UXP). It is also the primary tool for building Crossplane packages and pushing them to registries.

For users who wish to use other OCI clients for pushing packages, docker-credential-up is an implementation of the Docker credential helper protocol and can be used as an authentication mechanism for pushing packages by adding it your Docker config file.

Minimum Supported Versions

github.com/crossplane/crossplane: v1.6.0

Notably, this version does not support the v1beta1 API versions of CompositeResourceDefinition and Composition from apiextensions.crossplane.io. Please update to use the v1 equivalent if necessary.

Install

Both up and docker-credential-up can be downloaded by using the official installation script, or can be installed via a variety of common package managers.

Install Script:

up

curl -sL https://cli.upbound.io | sh

docker-credential-up

curl -sL https://cli.upbound.io | BIN=docker-credential-up sh

Homebrew

up

brew install upbound/tap/up

docker-credential-up

brew install upbound/tap/docker-credential-up

Deb/RPM Packages

Deb and RPM packages are available for Linux platforms, but currently require manual download and install.

up

curl -sLo up.deb https://cli.upbound.io/stable/${VERSION}/deb/linux_${ARCH}/up.deb

docker-credential-up

curl -sLo up.deb https://cli.upbound.io/stable/${VERSION}/deb/linux_${ARCH}/docker-credential-up.deb

up

curl -sLo up.rpm https://cli.upbound.io/stable/${VERSION}/rpm/linux_${ARCH}/up.rpm

docker-credential-up

curl -sLo up.rpm https://cli.upbound.io/stable/${VERSION}/rpm/linux_${ARCH}/docker-credential-up.rpm

Nix

The up CLI is available via Nixpkgs via the upbound attribute. To install using nix-env:

nix-env -iA upbound

To install using the unified nix CLI:

nix profile install upbound

Both installation methods install both the docker-credential-up and up executables.

Setup

Users typically begin by either logging in to Upbound or installing UXP.

Upbound Login

up uses profiles to manage sets of credentials for interacting with Upbound Cloud and Upbound Enterprise. You can read more about how to manage multiple profiles in the configuration documentation. If no --profile flag is provided when logging in the profile designated as default will be updated, and if no profiles exist a new one will be created with name default and it will be designated as the default profile.

up login

Install Universal Crossplane

up can install UXP into any Kubernetes cluster, or upgrade an existing Crossplane installation to UXP of compatible version. UXP versions with the same major, minor, and patch number are considered compatible (e.g. v1.2.1 of Crossplane is compatible with UXP v1.2.1-up.N)

To install the latest stable UXP release:

up uxp install

To upgrade a Crossplane installation to a compatible UXP version:

up uxp upgrade vX.Y.Z-up.N -n <crossplane-namespace>

Build and Push Packages

up can be used to build and push Crossplane packages. If pushing to Upbound, the same credentials acquired via up login can be used.

To build a package in your current directory:

up xpkg build

To push the package:

up xpkg push hasheddan/cool-xpkg:v0.1.0

If you prefer to use Docker, or any other OCI client, you can add the following to your config file after downloading docker-credential-up to use your Upbound credentials when pushing.

{
	"credHelpers": {
		"xpkg.upbound.io": "up",
		"registry.upbound.io": "up"
	}
}

Usage

See the documentation on supported commands and common workflows for more information.
