Note that the instructions given below are applicable only if you are a non-subscription user and your WSO2 API Manager distribution has no WUM updates.

If you have a WUM-updated pack, go to Migrating the APIs to a Different Environment

To know more about WUM updates see, Updating WSO2 API Manager.


WSO2 API Manager (WSO2 API-M) allows you to maintain multiple environments running on the same WSO2 API-M version. This feature allows you to import and export applications or APIs between your environments. For example, if you have an application or API running in the development environment, you can import it and export to the test(QA) environment. Thereby, APIs and applications do not have to be created from scratch in different environments.

Getting Started

After running the CLI tool make sure to add an environment before you start working with the import/export CLI commands, because all APIs and applications need to be imported or exported to a specific environment.

Running the CLI tool

Step 1 - Deploy the API import/export tool

  1. Download the latest version of WSO2 API Manager from http://wso2.com/products/api-manager/.

  2. Start WSO2 API Manager.

  3. Download the latest WSO2 API import/export tool (api-import-export-2.6.0-v14.war) from  here.

    • Note that the import/export tool attached is specific to this version of WSO2 API Manager.

    • Make sure to delete all previous versions of the web app (e.g., api-import-export-2.6.0-v14.war), both the compressed and the extracted files, before copying over the new web app.

    • This version of the API Import and Export web application is compatible with the WSO2 WUM updates from July 8, 2019, onwards. For more information on updating WSO2 API Manager, see Updating WSO2 API Manager.
    • The previous version of the web application which is compatible with WUM updates that are prior to the above-mentioned date can be download from here.
    • Note that API update support in the targeted environment is available only with the api-import-export-2.6.0-v14.war version.

  4. Copy the downloaded api-import-export-2.6.0-v14.war file to the <API-M_HOME>/repository/deployment/server/webapps folder.
    The file is automatically deployed as hot deployment is enabled.


Step 2- Run the CLI tool
  1. Navigate to the API Management Tooling page - https://wso2.com/api-management/tooling/
  2. Go to the previous releases link under Dev-Ops Tooling page and select the 2.6.0 as product version.

  3. Select a generated archive suitable for your platform (i.e., Mac, Windows, Linux) and extract it the CLI tool that you downloaded to a desired location and cd into it.

  4. Navigate to the working directory where the executable CLI Tool resides.

  5. Execute the following command to start the CLI tool.

    ./apimcli

  6. Add the location of the extracted folder to your system's $PATH variable to be able to access the executable from anywhere.

    For further instructions execute the following command.

    apimcli --help
Global flags for CLI tool

The following are some global flags that you can use with the CLI tool.

      --verbose
           Enable verbose logs (Provides more information on execution)
      --insecure, -k
          Allow connections to SSL sites without certs
      --help, -h
          Display information and example usage of a command

Adding an environment

You can add environments by either manually editing the $HOME/.wso2apimcli/main_config.yaml file or by running the following CLI command.

apimcli add-env

The directory structure for the configuration files ( $HOME/.wso2apimcli ) will be created upon execution of the apimcli command.

  1. Make sure that WSO2 API Manager is started and that the CLI import/export tool is running. 

  2. Run the following CLI command to add an environment.

    apimcli add-env -n <environment-name> \
                        --registration <registration-endpoint> \
                        --apim <API-Manager-endpoint> \
                        --token <token-endpoint> \
                        --import-export <endpoint-for-environment> \
                        --admin <admin-REST-API-endpoint> \
                        --api_list <API-listing-REST-API-endpoint> \
                        --app_list <application-listing-REST-API-endpoint>

Migrating APIs to different environments

Exporting an API

  1. Make sure that WSO2 API Manager is started and that the CLI import/export tool is running. 
  2. Run the following CLI command to export an existing API as a .zip archive.
apimcli export-api -n <API-name> -v <version> -r <provider> -e <environment> -u <username> -p <password> -k
apimcli export-api --name <API-name> --version <version> --provider <provider> --environment <environment> --username <username> --password <password> --insecure

The username and password are optional flags. You will be prompted to enter your credentials if you do not provide these flags.

Flags:

  • Required flags:
    • --name, -n
    • --version, -v
    • --provider, -r
    • --environment, -e
    • --insecure, -k : This allows connections to SSL sites without certificates
  • Optional flags:
    • --username, -u
    • --password, -p
apimcli export-api -n PhoneVerification -v 1.0.0 -r admin -e dev -u admin -p admin -k
Succesfully exported API!
Find the exported API at /Users/kim/.wso2apimcli/exported/apis/dev/PhoneVerification_1.0.0.zip

Importing an API

You can use the archive created in the previous section to import APIs to an API Manager instance.

  1. Make sure that WSO2 API Manager is started and that the CLI import/export tool is running. 

    For Secure Endpoint Enabled APIs:

    If you have enabled secure endpoints when creating the API and your username or/and password differs in the two environments, please follow the steps below before importing the API.

    1. Unzip the .zip archive created in the previous section.

    2. Go to the <API-name-version>/Meta-information directory and open the api.json file.
    For example, PhoneVerification_1.0.0/Meta-information directory and open the api.json file.

    3. Modify the endpointUTPassword with your endpoint password and save the api.json file.

    4. Compress the PhoneVerification_1.0.0 folder to a folder named myExportedAPI.

  • Run the following CLI command to import an API.

    apimcli import-api -f <environment>/<file> -e <environment> -u <username> -p <password> -k
    apimcli import-api --file <environment>/<file> --environment <environment> --username <username> --password <password> --insecure

    The username and password are optional flags. You will be prompted to enter your credentials if you do not provide these flags.

    Flags:

    • Required flags:
      • --file, -f : The file path of the exported API. For example, if your file path is /Users/kim/.wso2apimcli/exported/apis/dev/PhoneVerification_1.0.0.zip., then you need to enter dev/PhoneVerification_1.0.0.zip as the value for this flag.
      • --environment, -e : The environment to which you what to import the API to.
      • --insecure, -k : This a llows connections to SSL sites without certificates
    • Optional flags:
      • --username, -u
      • --password, -p
    apimcli import-api -f dev/PhoneVerification_1.0.0.zip -e production -u admin -p admin -k
    Sample Response
    ZipFilePath: /Users/kim/.wso2apimcli/exported/apis/dev/PhoneVerification_1.0.0.zip
Successfully imported API 'dev/PhoneVerification_1.0.0.zip'
Succesfully imported API!

    You must add a parameter named --preserve-provider to the CLI command and set its value to false if the API is imported to a different domain than its exported one. This parameter sets the provider of the imported API to the user who is issuing the CLI command. Here's an example:

    apimcli import-api -k -f <environment>/<file> -e <environment> -u <username> -p <password> --preserve-provider <preserve_provider>
    apimcli import-api --insecure --file <environment>/<file> --environment <environment> -u <username> -p <password> --preserve-provider=<preserve_provider>

    The username and password are optional flags. You will be prompted to enter your credentials if you do not provide these flags.

    Flags:

    • Required flags:
      • --insecure, -k : This a llows connections to SSL sites without certificates
      • --file, -f
      • --environment, -e : The environment to which you what to import the API to.
      • --preserve-provider (This does not have a short flag)
    • Optional flags:
      • --username, -u
      • --password, -p
    apimcli import-api -k -f dev/PhoneVerification_1.0.0.zip -e production -u admin -p admin --preserve-provider=false

    The --preserve-provider flag is used to decide whether to keep the actual Provider as the provider of the API or change the provider to the user who is importing the API to a different environment.

    As an example, If --preserve-provider is set to true, when importing an API created by user-1 in environment-1 will be preserved as the provider when and after importing that API to environment-2 by user-2. If --preserve-provider is set to false, when importing that API created by user-1 to the environment-2, the provider will be changed (not preserved) to user-2 who is importing the API.

    Troubleshooting

    After importing, if the APIs are not visible in the API Publisher UI, do the following to re-index the artifacts in the registry.

    1. Rename the <lastAccessTimeLocation> element in the <API-M_2.6.0_HOME>/repository/conf/registry.xml file. If you use a clustered/distributed API Manager setup, change the file in the API Publisher node. For example, change the /_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime registry path to /_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime_1.

    2. Shut down the API Manager 2.6.0, backup and delete the <API-M_2.6.0_HOME>/solr directory.

      For more information, see Upgrading the API Manager to 2.6.0.

Importing/exporting an API in a tenanted environment

The environments that you create will be common to the admin and the tenants. Therefore, you do not need to create environments again when exporting and importing APIs between tenanted environments.


  • To export an API from a tenant, follow the steps in Export an API. Use the tenant-specific encoded credentials in the CLI command. Here's an example: 

    apimcli export-api -n <API-name> -v <version> -r <provider> -e <environment> -u <username> -p <password> -k
    apimcli export-api --name <API-name> -version <version> --provider <provider> --environment <environment> --username <username> --password <password> --insecure

    The username and password are optional flags. You will be prompted to enter your credentials if you do not provide these flags.

    Flags:

    • Required flags:
      • --name, -n
      • --version, -v
      • --provider, -r
      • --environment, -e : The environment to which you what to export the API to.
      • --insecure, -k : This allows connections to SSL sites without certificates
    • Optional flags:
      • --username, -u
      • --password, -p
    apimcli export-api -n PizzaShackAPI -v 1.0.0 -r chris@test.com -e dev -u chris@test.com -p chris123 -k
    Sample Response
    Succesfully exported API!
Find the exported API at /Users/kim/.wso2apimcli/exported/apis/dev/PizzaShackAPI_1.0.0.zip

  • To import the API in another tenant, follow the steps in Importing an API. Use the encoded credentials for this tenant in the CLI command. Here's an example:

    apimcli import-api -f <environment>/<file> -e <environment> -u <username> -p <password> --preserve-provider <preserve_provider>
    apimcli import-api --file <environment>/<file> --environment <environment> --username <username> --password <password> --preserve-provider <preserve_provider>

    The username and password are optional flags. You will be prompted to enter your credentials if you do not provide these flags.

    Flags:

    • Required flags:
      • --file, -f
      • --environment, -e : The environment to which you what to import the API to.
      • --insecure, -k : This allows connections to SSL sites without certificates
      • --preserve-provider
    • Optional flags:
      • --username, -u
      • --password, -p
    apimcli import-api -f dev/PizzaShackAPI_1.0.0.zip -e production -u nick@example.com -p nick123 --preserve-provider=false -k
    ZipFilePath: /Users/kim/.wso2apimcli/exported/apis/dev/PizzaShackAPI_1.0.0.zip
Successfully imported API 'dev/PizzaShackAPI_1.0.0.zip'
Succesfully imported API!

    Note that the --preserve-provider flag value should be set to false.

Migrating applications to different environments

Managing application lifecycle

The lifecycle of an application could be defined as the stages of an application between the development and production environments. The feature facilitates to manage the application life cycle by allowing the user to migrate the applications within desired environments. The user should have admin permissions in order to use this.

Exporting an application

You can export applications in the API Store and download them as a zipped file.

  1. Make sure that WSO2 API Manager is started and that the CLI import/export tool is running. 
  2. Run the following CLI command to export an existing application as a .zip archive.
apimcli export-app -n <application-name> -o <owner> -e <environment> -u <username> -p <password> -k
apimcli export-app --name <application-name> --owner <owner> --environment <environment> --username <username> --password <password> --insecure

The username and password are optional flags. You will be prompted to enter your credentials if you do not provide these flags.

Flags:

  • Required flags:
    • --name, -n
    • --owner, -o
    • --environment, -e : The environment to which you what to export the application to.
    • --insecure, -k : This allows connections to SSL sites without certificates
  • Optional flags:
    • --username, -u
    • --password, -p
apimcli export-app -n SampleApp -o admin -e dev -u admin -p admin -k
Succesfully exported Application!
Find the exported Application at /Users/kim/.wso2apimcli/exported/apps/dev/admin_SampleApp.zip

The zipped file will be as follows:

<exported-Application>.zip 
└── <Application-Name> 
└── <Application-Name>.json

Importing an application

You can import an application to your environment as a zipped application. When you import an application as a zipped file, a new application is created within the target environment.

  1. Make sure that WSO2 API Manager is started and that the CLI import/export tool is running. 
  2. Run the following CLI command to import an existing application as a .zip archive.
apimcli import-app -f <environment>/<file> -e <environment> -s <skip_subscriptions> -o <owner> -r <preserve_owner> -k            
apimcli import-app --file <environment>/<file> --environment <environment> --skipSubscriptions <skip_subscriptions> --owner <owner> --preserveOwner <preserve_owner> --insecure

The username and password are optional flags. You will be prompted to enter your credentials if you do not provide these flags.

Flags:

  • Required flags
    • --file, -f : The file path of the exported App. For example, if your file path is /Users/kim/.wso2apimcli/exported/apps/dev/admin_SampleApp.zip , then you need to enter dev/admin_SampleApp.zip as the value for this flag.
    • --environment, -e : The environment to which you what to import the application to.
    • --insecure, -k : This allows connections to SSL sites without certificates
  • Optional flags
    • --skipSubscriptions, -s
      You can opt to skip importing the subscriptions of the application by defining this flag. This parameter is set to false by default.
    • --owner, -o The owner of the imported application can be specified by providing an username of a valid user based on your preference. The application importer can set the preferred owner’s username as the value of the  --owner or -o flag.
    • --preserveOwner, -r
      You can also import the application by preserving the application owner's information, from the previous environment. The application importer can add the --preserveOwner or -r flag in order to define that this flag is set to true. This parameter is set to false by default. Therefore, the default value is used when you do not define this flag. If you import the application without specifying any of the optional flags, you will be added as the owner of the application in the imported environment. If both the --owner and the --preserveOwner flags are set, then the --owner flag gets higher priority over the --preserveOwner flag. 
apimcli import-app -f dev/admin_SampleApp.zip -e production -o admin --preserveOwner --skipSubscriptions -u admin -p admin -k
ZipFilePath: /Users/kim/.wso2apimcli/exported/apps/dev/admin_SampleApp.zip
Completed importing the Application 'dev/admin_SampleApp.zip'
Succesfully imported Application!

Importing applications in a single-tenant environment

There are three options to import applications in a single-tenant environment.

  • Application A in environment 1 is migrated to environment 2. Some APIs may not be available in environment 2 (API B in this case) and the relevant subscriptions are not added in such cases (skipped).

  • A different owner can be specified while importing an application to environment 2,  without preserving the original user of environment 1.
  • The original owner of the application can be preserved when the application is imported to environment 2 by adding the --preserveOwner flag.


Importing applications in a multi-tenant environment

In a situation where an application has API subscriptions in different tenant domains, such subscriptions are added if the relevant APIs with the target tier, are available in the importing environment. Note that the provider of the API may not be the same in the importing environment.

List apps

  1. Make sure that WSO2 API Manager is started and that the CLI import/export tool is running. 
  2. Run the following CLI command to list the apps.
apimcli list apps -e <environment> -u <username> -o <owner> -p <password> -k             
apimcli list apps --environment <environment> --owner <owner> --username <username> --password <password> --insecure

Flags:

  • Required flags
    • --environment, -e
    • --owner, -o
    • --insecure, -k : This a llows connections to SSL sites without certificates
  • Optional flags
    • --username, -u
    • --password, -p

The username and password are optional flags. You will be prompted to enter your credentials if you do not provide these flags.

Understanding the API import/export tool

The API import/export tool uses a RESTful API, protected by basic authentication.

Only the following types of users are allowed to access the API import/export tool. 

  • A user with the admin role.

  • A user with a role that has the API-M Admin, Login, and API Create permissions. 

     Click here to see a screen shot of the above listed permissions.

To allow access to the import/export feature only for a particular tenant, log in to WSO2 API Manager's Management Console and add the downloaded archive file as a web application to the server.

The 'admin' role is the default role which is specified in the Realm configuration in the <API-M-HOME>/repository/conf/user-mgt.xml   file. It will be changed if you have changed the value of the <AdminRole> parameter as shown below.

<Realm>
        <Configuration>
		<AddAdmin>true</AddAdmin>
            <AdminRole>admin</AdminRole>            
         .....
       </Configuration>
</Realm>

The export functionality

The API export functionality retrieves the information required for the requested API from the registry and databases and generates a ZIP file, which the exporter can download. This exported ZIP file has the following structure:

Structure of the exported ZIP file

The structure of the ZIP file is explained below:

Sub directory/FileDescription

Meta Information

  • api.json: contains all the basic information required for an API to be imported to another environment

  • swagger.json: contains the API swagger definition

Documents

  • docs.json: contains the summary of all the documents available for the API

  • Add the uploaded files for API documentation also

The import functionality

The import functionality uploads the exported ZIP file of the API to the target environment. It creates a new API with all the registry and database resources exported from the source environment. Note the following:

  • The lifecycle status of an imported API will always be CREATED even when the original API in the source environment has a different state. This is to enable the importer to modify the API before publishing it.
  • Tiers and sequences are provider-specific. If an exported tier is not already available in the imported environment, that tier is not added to the new environment. However, if an exported sequence is not available in the imported environment, it is added.
  • The importer can decide whether to keep the original provider’s name or replace it. Set the  --preserve-provider  flag to true to keep it. If you set it to false, the original provider is replaced by the user who is sending the CLI command. 
  • Cross-tenant imports are not allowed by preserving the original provider. For example, if an API is exported from tenant A and imported to tenant B, the value of the --preserve-provider flag must always be false.
