Tasty repository

Tasty is a CLI to handle operators in a package manager fashion.

The tool provides the following primitives to interact with olm:

• list
• info
• install
• remove
• search

Additionally, it can be used as a go library

As an alternative, consider kubectl-operator

Demo!

Installing

curl -s -L https://github.com/karmab/tasty/releases/latest/download/tasty-linux-amd64 > /usr/bin/tasty
chmod u+x /usr/bin/tasty

Some tasty install samples

• Install OLM operators changing the sourceNamespace value

tasty install assisted-service-operator hive-operator --sourcens olm

• Install OLM operators changing the CatalogSource and sourceNamespace value

tasty install assisted-service-operator hive-operator --source certified-operators --sourcens olm

• Print yaml of OLM operator without install

tasty install assisted-service-operator

Requirements

Kubeconfig environment variable must be set

export KUBECONFIG=/path/to/kubeconfig

Alternatively, you can rely on your ~/.kube/config

Running as kubelet and oc plugin

Run the following and you can then use kubectl olm or oc olm

tasty config --enable-as-plugin

Using as a go library

Import tasty:

import "github.com/karmab/tasty/pkg/operator"

Then, create an operator using the constructor:

o := operator.NewOperator()

or with specific options:

o := operator.NewOperatorWithOptions(name, source, defaultChannel, description, csv, namespace, crd, configExecFile, configExecPath string)

The following methods are available to manage the operator:

o.SearchOperator()
o.GetList()
o.GetInfo()
o.SetConfiguration()
o.GetOperator()
o.InstallOperator()

Installing operators from a pod

Check job.yml.sample as an example of a job that will install a given operator using a sa with cluster admin privileges
