Step 5: Create an environment group

In this step, you will create an environment and an environment group.

In Apigee, API proxies are deployed to environments, which provide isolated contexts for your proxies. Environments are organized into environment groups, which provide hostnames for all the proxies deployed to environments within the group. You must have at least one environment and at least one environment group. To learn more, see About environments and environment groups.

Create an environment

Create the environment first before creating the environment group. You can create an environment using the Apigee hybrid UI or using the CLI. You may want to use the UI for these steps to familiarize yourself with it.

Apigee hybrid UI

To access the hybrid UI and add an environment, perform the following steps:

  1. Open the Apigee UI. If this is the first time you are logging in, hybrid displays a consent dialog. If you are prompted to select from more than one account, choose the account that owns the project you created in Step 2: Create a Google Cloud project. Then click Allow.
  2. Your browser navigates to the hybrid UI main landing page:

    The landing page in the Apigee
    hybrid UI, which consists of left-hand navigation and large images that are links.

  3. Ensure that your hybrid-enabled organization is selected from the organization drop-down list. If it is not selected, select it from the drop-down list, as the following example shows:

    A list of organizations that are hybrid enabled

  4. Click Admin > Environments > Overview.

    The Apigee hybrid UI menu showing Admin, Environments, Overview expanded

    The Environments view is displayed, with no environments (yet):

    The Environments view, which is blank (no environments)

  5. Click +Environment.

    The New environment dialog is displayed:

    The new environment dialog

  6. Enter the following information in the New Environment dialog:
    1. Display name (Required): A friendly name for the environment that is used in the UI. For example, My First Environment or test. Unlike the Environment name, the Display name can include uppercase and other special characters.
    2. Environment name (Required): The programmatic name for the environment; also known as the environment ID.

      For example, my-environment or test.

      The Display name and the Environment name can be different.

    3. Description (Optional): Additional information about the environment that you want to add as a reminder of the purpose of the environment. For example, Created during initial installation.
  7. Click Create.

    Apigee creates the new environment and indicates that it is Pending Provisioning:

    Pending Provisioning status
    message

    In a few moments, it changes to provisioned:

    New
    environment was provisioned message

    However, you're not quite done. You also need to add your new environment to the runtime's overrides.yaml file—but first you've got to install the runtime, so let's not get ahead of ourselves.

gcloud CLI

To create an environment with the Create environments API, perform the following steps:

  1. Open a terminal on the device you are using to manage Apigee.
  2. On the command line, get your gcloud authentication credentials, as the following example shows:

    TOKEN=$(gcloud auth print-access-token)

    To check that your token was populated, use echo, as the following example shows:

    echo $TOKEN

    This should display your token as an encoded string.

    For more information, see gcloud command-line tool overview.

  3. Create environment variables for the elements of the environment. You will use the following variable in the command to create it:
    • ENV_NAME (Required) is the programmatic ID for your environment. The environment name can contain lowercase letters, dashes, and numbers and must start with a lowercase letter. This name will be used as the identifier and cannot be changed after creation
      export ENV_NAME=ENVIRONMENT_NAME
    • ENV_DISPLAY_NAME (Required) is the user-friendly name of your environment. This value does not need to be unique, and can include spaces and special characters. For example, "My Example Environment".
      ENV_DISPLAY_NAME=FRIENDLY_NAME
    • ORG_NAME (Required) is your organization ID. Make sure you have defined the ORG_NAME environment variable from Step 4: Create an organization:
      echo $ORG_NAME
    • ENV_DESCRIPTION (Optional) is information about the environment that you'd like to use as a reminder of its purpose. For example, "Example environment for Apigee Hybrid instructions".
      ENV_DESCRIPTION=DESCRIPTION_TEXT
  4. Send an authenticated POST request to the Create environments API.

    The following example shows the request structure that creates an organization, using the following command:

    curl -H "Authorization: Bearer $TOKEN" -X POST -H "content-type:application/json"   -d '{
        "name": "'"$ENV_NAME"'",
        "displayName": "'"$ENV_DISPLAY_NAME"'",
        "description": "'"$ENV_DESCRIPTION"'"
      }'   "https://apigee.googleapis.com/v1/organizations/$ORG_NAME/environments"

    On a successful creation request, the Environments API should respond with a message similar to the following:

    {
      "name": "organizations/hybrid-example/operations/c2aee040-7e79-4fd4-b0cf-79ca1b7098a8",
      "metadata": {
        "@type": "type.googleapis.com/google.cloud.apigee.v1.OperationMetadata",
        "operationType": "INSERT",
        "targetResourceName": "organizations/hybrid-example/environments/example-env",
        "state": "IN_PROGRESS"
      }
    }

    As the state property in the response indicates, Apigee has started to create the new environment, so its state is IN_PROGRESS. This process can take several minutes.

Create an environment group

Now create an environment group and assign the environment you just created to it. Environment groups allow you to group environments together, and provide the hostnames for routing the proxies deployed to the environments within the group. You must create at least one environment group, and you must assign at least one hostname to the group. For an overview of environment groups, see About environments and environment groups.

Apigee hybrid UI

To create an environment group using the Apigee UI, perform the following steps:

  1. Open the Apigee UI.
  2. Your browser navigates to the hybrid UI main landing page.

  3. Ensure that your hybrid-enabled organization is selected from the organization drop-down list. If it is not selected, select it from the drop-down list.
  4. Click Admin > Environments > Groups.

    The Environment Groups Overview view is displayed, with any created environment groups:

    The Environment groups view, showing any created groups

  5. Click +Environment Group.

    The Add an Environment Group dialog is displayed.

    Add Environment Group dialog showing blank Name field

  6. Enter a name and then click Add.
  7. Hold the pointer over the newly-created environment group and then click Edit .

    Add a hostname that all proxies deployed to environments within this group will use. This should be a domain you have management access to. If you need to register a domain, see a domain registrar like Google Domains.

  8. Edit Environment Group window showing no environments assigned

  9. Click Add (+).
  10. The Add environment dialog displays.
  11. Add environment dialog listing available environments

  12. Select an environment from the list and then click Add.

gcloud CLI

To create an environment group using the command line, perform the following steps:

  1. On the command line, get your gcloud authentication credentials, as the following example shows:

    TOKEN=$(gcloud auth print-access-token)

    To check that your token was populated, use echo, as the following example shows:

    echo $TOKEN

    This should display your token as an encoded string.

    For more information, see gcloud command-line tool overview.

  2. Make sure you have the DOMAIN environment variable set as the following example shows:
    echo $DOMAIN

    This is the hostname that all proxies deployed to environments within this group will use. This should be a domain you have management access to.

    If it is not set, create it with the domain you plan to use for your Apigee hybrid installation. For example:

    export DOMAIN=YOUR-DOMAIN.COM
  3. Make sure you have the ENV_NAME environment variable set to the environment you just created in the previous steps. For example:
    echo $ENV_NAME
  4. Create an environment variable for your intended environmnet group name. For example:
    export ENV_GROUP=ENVIRONMENT_GROUP_NAME
  5. Create the environment group with the following command:
    curl -H "Authorization: Bearer $TOKEN" -X POST -H "content-type:application/json" \
       -d '{
         "name": "'"$ENV_GROUP"'",
         "hostnames":["'"$DOMAIN"'"]
       }' \
       "https://apigee.googleapis.com/v1/organizations/$ORG_NAME/envgroups"
        
  6. Assign the environment to the new group with the following command:
    curl -H "Authorization: Bearer $TOKEN" -X POST -H "content-type:application/json" \
       -d '{
         "environment": "'"$ENV_NAME"'",
       }' \
       "https://apigee.googleapis.com/v1/organizations/$ORG_NAME/envgroups/$ENV_GROUP/attachments"
