CLI Guide

Usage:
  operator-sdk [command]

Global Flags

--verbose - enable debug logging

build

Args

image - is the container image to be built, e.g. "quay.io/example/operator:v0.0.1".

Flags

--image-build-args string - extra, optional image build arguments as one string such as "--build-arg https_proxy=$https_proxy" (default "")
--image-builder string - tool to build OCI images. One of: [docker, buildah] (default "docker")
-h, --help - help for build

Use

The operator-sdk build command compiles the code and builds the executables. After build completes, the image is built locally using the image builder specified by the --image-builder flag (default docker). Then it needs to be pushed to a remote registry.

Example

Build

$ operator-sdk build quay.io/example/operator:v0.0.1

generate

k8s

├── appservice_types.go
├── doc.go
├── register.go
└── zz_generated.deepcopy.go

openapi

test

Available Commands

local

Runs the tests locally

Args

test-location - location of e2e test files (e.g. "./test/e2e/")

Flags

--debug - Enable debug-level logging
--kubeconfig string - location of kubeconfig for Kubernetes cluster (default "~/.kube/config")
--global-manifest string - path to manifest for global resources (default "deploy/crd.yaml)
--namespaced-manifest string - path to manifest for per-test, namespaced resources (default: combines deploy/service_account.yaml, deploy/rbac.yaml, and deploy/operator.yaml)
--namespace string - if non-empty, single namespace to run tests in (e.g. "operator-test") (default: "")
--go-test-flags string - Additional flags to pass to go test
--molecule-test-flags string - Additional flags to pass to molecule test
--up-local - enable running operator locally with go run instead of as an image in the cluster
--no-setup - disable test resource creation
--image string - use a different operator image from the one specified in the namespaced manifest
-h, --help - help for local

Use

The operator-sdk test command runs go tests built using the Operator SDK's test framework.

Example

$ operator-sdk test local ./test/e2e/
ok    github.com/operator-framework/operator-sdk-samples/memcached-operator/test/e2e  20.410s

up

Available Commands

local - Launches the operator locally

Use

The operator-sdk up local command launches the operator on the local machine with the ability to access a Kubernetes cluster using a kubeconfig file, and setting any necessary environment variables that the operator would expect to find when running in a cluster. For Go-based operators, this command will compile and run the operator binary. In the case of non-Go operators, it runs the operator-sdk binary itself as the operator.

Flags

--go-ldflags string - Set Go linker options
--kubeconfig string - The file path to Kubernetes configuration file; defaults to $HOME/.kube/config
--namespace string - The namespace where the operator watches for changes. (default "default")
--operator-flags string - Flags that the local operator may need.
-h, --help - help for local

Example

$ operator-sdk up local --kubeconfig "mycluster.kubecfg" --namespace "default" --operator-flags "--flag1 value1 --flag2=value2"

The below example will use the default kubeconfig, the default namespace environment var, and pass in flags for the operator. To use the operator flags, your operator must know how to handle the option. Below imagine an operator that understands the resync-interval flag.

$ operator-sdk up local --operator-flags "--resync-interval 10"

If you are planning on using a different namespace than the default, then you should use the --namespace flag to change where the operator is watching for custom resources to be created. For this to work your operator must handle the WATCH_NAMESPACE environment variable. To do that you can use the utility function k8sutil.GetWatchNamespace in your operator.

$ operator-sdk up local --namespace "testing"

Flags

-h, --help - help for up
