##格式

$ operator-sdk  [] [] []      

1. operator-sdk build

指令編譯代碼并生成可執行檔案

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

2. operator-sdk completion

生成bash補全

operator-sdk completion      

3. operator-sdk print-deps

指令顯示操作員所需的最新Golang軟體包和版本。預設情況下，它以列格式列印

operator-sdk print-deps --as-file      

4. operator-sdk generate

指令将調用特定的生成器以根據需要生成代碼

5. operator-sdk olm-catalog gen-csv

子指令将叢集服務版本（CSV）清單和可選的自定義資源定義（CRD）檔案寫入 ​

​deploy/olm-catalog/<operator_name>/<csv_version>​

​

$ operator-sdk olm-catalog gen-csv --csv-version 0.1.0 --update-crds
INFO[0000] Generating CSV manifest version 0.1.0
INFO[0000] Fill in the following required fields in file deploy/olm-catalog/operator-name/0.1.0/operator-name.v0.1.0.clusterserviceversion.yaml:
  spec.keywords
  spec.maintainers
  spec.provider
  spec.labels
INFO[0000] Created deploy/olm-catalog/operator-name/0.1.0/operator-name.v0.1.0.clusterserviceversion.yaml      

6. operator-sdk new

$ mkdir $GOPATH/src/github.com/example.com/
$ cd $GOPATH/src/github.com/example.com/
$ operator-sdk new app-operator
$ operator-sdk new app-operator \
    --type=ansible \
    --api-version=app.example.com/v1alpha1 \
    --kind=AppService      

7. operator-sdk add

指令将控制器或資源添加到項目中。該指令必須從Operator項目的根目錄運作。

7.1 Example add api output

$ operator-sdk add api --api-version app.example.com/v1alpha1 --kind AppService
Create pkg/apis/app/v1alpha1/appservice_types.go
Create pkg/apis/addtoscheme_app_v1alpha1.go
Create pkg/apis/app/v1alpha1/register.go
Create pkg/apis/app/v1alpha1/doc.go
Create deploy/crds/app_v1alpha1_appservice_cr.yaml
Create deploy/crds/app_v1alpha1_appservice_crd.yaml
Running code-generation for Custom Resource (CR) group versions: [app:v1alpha1]
Generating deepcopy funcs

$ tree pkg/apis

├── addtoscheme_app_appservice.go
├── apis.go
└── app
  └── v1alpha1
    ├── doc.go
    ├── register.go
    ├── types.go      

7.2 Example add controller output

$ operator-sdk add controller --api-version app.example.com/v1alpha1 --kind AppService
Create pkg/controller/appservice/appservice_controller.go
Create pkg/controller/add_appservice.go

$ tree pkg/controller
pkg/controller/
├── add_appservice.go
├── appservice
│   └── appservice_controller.go
└── controller.go      

7.3 Example add crd output

$ operator-sdk add crd --api-version app.example.com/v1alpha1 --kind AppService
Generating Custom Resource Definition (CRD) files
Create deploy/crds/app_v1alpha1_appservice_crd.yaml
Create deploy/crds/app_v1alpha1_appservice_cr.yaml      

8. operator-sdk up local

$ operator-sdk up local \
  --kubeconfig "mycluster.kubecfg" \
  --namespace "default" \
  --operator-flags "--flag1 value1 --flag2=value2"
$ operator-sdk up local --operator-flags "--resync-interval 10"
$ operator-sdk up local --namespace "testing"
