Pulumi ESC: Go SDK

    The Go SDK for Pulumi ESC (Environments, Secrets, and Configuration) allows you to automate Pulumi ESC.

    Here are some of the scenarios the SDK can automate:

    • List environments and read environment definitions
    • Open enviroments to access config and resolve secrets
    • Create, update, decrypt, and delete environment definitions
      • Supports both structured types and yaml text
    • List environment revisions and create new revision tags
    • Check environment definitions for errors

    Install the SDK package

    Run go get github.com/pulumi/esc-sdk/sdk to install the SDK package.

    Examples

    These samples show how to create an EscClient with an access token and use it to perform varias ESC tasks.

    All of these example expects a PULUMI_ACCESS_TOKEN and PULUMI_ORG environment variable to be set.

    Manage environment example

    This example creates a new environment, opens that environment to access a secret, and the list the environments.

    package main

import (
	"log"
	"os"

	esc "github.com/pulumi/esc-sdk/sdk/go"
)

func main() {
	accessToken := os.Getenv("PULUMI_ACCESS_TOKEN")
	orgName := os.Getenv("PULUMI_ORG")
	configuration := esc.NewConfiguration()
	escClient := esc.NewClient(configuration)
	authCtx := esc.NewAuthContext(accessToken)

	projName := "examples"
	envName := "sdk-go-example"
	// Create Environment
	err := escClient.CreateEnvironment(authCtx, orgName, projName, envName)
	if err != nil {
		log.Fatalf("Failed to create environment: %v", err)
	}

	// Update Environment with Secrets
	updatePayload := &esc.EnvironmentDefinition{
		Values: &esc.EnvironmentDefinitionValues{
			AdditionalProperties: map[string]interface{}{
				"my_secret": map[string]string{
					"fn::secret": "shh! don't tell anyone",
				},
			},
		},
	}

	_, err = escClient.UpdateEnvironment(authCtx, orgName, projName, envName, updatePayload)
	if err != nil {
		log.Fatalf("Failed to update environment: %v", err)
	}

	// Open and View Secrets
	_, values, err := escClient.OpenAndReadEnvironment(authCtx, orgName, projName, envName)
	if err != nil {
		log.Fatalf("Failed to open environment: %v", err)
	}

	mySecret, ok := values["my_secret"]
	if !ok {
		log.Fatalf("Secret 'my_secret' not found in environment %s/%s", projName, envName)
	}

	log.Printf("my_secret: %v\n", mySecret)

	orgEnvs, err := escClient.ListEnvironments(authCtx, orgName, nil)
	if err != nil {
		log.Fatalf("Failed to list environments: %v", err)
	}

	for _, orgEnv := range orgEnvs.Environments {
		log.Printf("Environment: %v/%v\n", orgEnv.Project, orgEnv.Name)
	}

}

    Tag revision example

    This example lists revisions for an environment, tags a revision, and lists revision tags.

    package main

import (
	"log"
	"os"

	esc "github.com/pulumi/esc-sdk/sdk/go"
)

func main() {
	accessToken := os.Getenv("PULUMI_ACCESS_TOKEN")
	orgName := os.Getenv("PULUMI_ORG")
	configuration := esc.NewConfiguration()
	escClient := esc.NewClient(configuration)
	authCtx := esc.NewAuthContext(accessToken)

	projName := "examples"
	envName := "sdk-go-example"
	revs, err := escClient.ListEnvironmentRevisions(authCtx, orgName, projName, envName)
	if err != nil {
		log.Fatalf("Failed to list environment revisions: %v", err)
	}

	if len(revs) < 2 {
		return
	}

	// get the second latest revision
	secondLatestRev := revs[1]
	err = escClient.CreateEnvironmentRevisionTag(authCtx, orgName, projName, envName, "stable", secondLatestRev.Number)
	if err != nil {
		log.Fatalf("Failed to tag environment revision: %v", err)
	}

	log.Printf("Tagged revision %d as 'stable'", secondLatestRev.Number)

	tags, err := escClient.ListEnvironmentRevisionTags(authCtx, orgName, projName, envName)
	if err != nil {
		log.Fatalf("Failed to list environment revision tags: %v", err)
	}

	for _, tag := range tags.Tags {
		log.Printf("Tag %s at revision %d", tag.Name, tag.Revision)
	}
}
