Code Engine Go SDK Example

Running example_v2.go

To run the example, create a Code Engine project from the Console or Code Engine CLI, and run the following commands from this directory:

  1. export CE_API_KEY=<Your IBM Cloud API key>
  2. export CE_PROJECT_REGION=<The region (e.g. 'us-south') of your Code Engine project>
  3. export CE_DOMAIN_MAPPING_NAME=<The name of your domain>
  4. export CE_TLS_CERT_FILE_PATH=<The path to your TLS certificate file>
  5. export CE_TLS_KEY_FILE_PATH=<The path to your TLS key file>
  6. go run example_v2.go

How-to

Set up an authenticator

authenticator := &core.IamAuthenticator{
    ApiKey:       os.Getenv("CE_API_KEY"),
    ClientId:     "bx", 
    ClientSecret: "bx",
    URL:          "https://iam.cloud.ibm.com",
}

Set up a Code Engine client

codeEngineServiceOptions := &codeenginev2.CodeEngineV2Options{
    Authenticator: authenticator,
    URL:           "https://api." + os.Getenv("CE_PROJECT_REGION") + ".codeengine.cloud.ibm.com/v2",
}
codeEngineService, err := codeenginev2.NewCodeEngineV2UsingExternalConfig(codeEngineServiceOptions)

Create a Code Engine project

projectName := "my-project"
createdProject, _, err := codeEngineService.CreateProject(&codeenginev2.CreateProjectOptions{
    Name: &projectName,
})

Create a Code Engine application

createAppOpts := codeEngineService.NewCreateAppOptions(
    *createdProject.ID,
    "icr.io/codeengine/helloworld",
    "my-app",
)
createdApp, _, err := codeEngineService.CreateApp(createAppOpts)

Create a Code Engine TLS secret

createTLSSecretOpts := codeEngineService.NewCreateSecretOptions(
    *createdProject.ID,
    "tls",
    "my-tls-secret",
)

tlsCert, _ := os.ReadFile(os.Getenv("CE_TLS_CERT_FILE_PATH"))
tlsKey, _ := os.ReadFile(os.Getenv("CE_TLS_KEY_FILE_PATH"))

createTLSSecretOpts.Data = &codeenginev2.SecretDataTLSSecretData{
    TlsCert: core.StringPtr(string(tlsCert)),
    TlsKey:  core.StringPtr(string(tlsKey)),
}
createdTLSSecret, _, err := codeEngineService.CreateSecret(createTLSSecretOpts)

Create a Code Engine domain mapping

domainMappingName := os.Getenv("CE_DOMAIN_MAPPING_NAME")
appComponentRef := &codeenginev2.ComponentRef{
    Name:          createdApp.Name,
    ResourceType: core.StringPtr("app_v2"),
}

createDomainMappingOpts := codeEngineService.NewCreateDomainMappingOptions(
    *createdProject.ID,
    appComponentRef,
    domainMappingName,
    *createdTLSSecret.Name,
)
createdDomainMapping, _, err := codeEngineService.CreateDomainMapping(createDomainMappingOpts)

Create a Code Engine function

createFunctionOpts := codeEngineService.NewCreateFunctionOptions(
    *createdProject.ID,
    "data:text/plain;base64,YXN5bmMgZnVuY3Rpb24gbWFpbihwYXJhbXMpIHsKICByZXR1cm4gewogICAgICBzdGF0dXNDb2RlOiAyMDAsCiAgICAgIGhlYWRlcnM6IHsgJ0NvbnRlbnQtVHlwZSc6ICdhcHBsaWNhdGlvbi9qc29uJyB9LAogICAgICBib2R5OiBwYXJhbXMgfTsKfQptb2R1bGUuZXhwb3J0cy5tYWluID0gbWFpbjs=",
    "my-function",
    "nodejs-18",
)

createdFunction, _, err := codeEngineService.CreateFunction(createFunctionOpts)
