+
+If you are running integration tests embedding 3scale or are doing a lot of 3scale demos, you might sooner or later **have plenty of services declared in the 3scale Admin console**, which could reveal difficult to work with.
+And with the new feature named *API-as-a-Product*, there are now **Backends and Products** to delete, making the cleanup by hand a bit tedious.
+
+This article explains how to cleanup a 3scale tenant using Ansible.
+
+## Pre-requisites
+
+Make sure Ansible is installed locally and is a fairly recent version.
+
+```
+$ ansible --version
+ansible 2.8.10
+  config file = /etc/ansible/ansible.cfg
+  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
+  ansible python module location = /usr/lib/python3.6/site-packages/ansible
+  executable location = /usr/bin/ansible
+  python version = 3.6.8 (default, Oct 11 2019, 15:04:54) [GCC 8.3.1 20190507 (Red Hat 8.3.1-4)]
+```
+
+Find the name of your 3scale Admin Portal and set it as a environment variable.
+
+For 3scale SaaS tenants, it will be something like this:
+
+```sh
+export ADMIN_PORTAL_HOSTNAME="<TENANT>-admin.3scale.net"
+```
+
+For 3scale 2.8 installed on-premises, you can find the default admin portal hostname by querying OpenShift.
+
+```sh
+export ADMIN_PORTAL_HOSTNAME="$(oc get route -l zync.3scale.net/route-to=system-provider -o go-template='{{(index .items 0).spec.host}}')"
+```
+
+Now, generate an Access Token with read/write privileges over the **Account Management API** and set it as a shell variable.
+
+```sh
+export THREESCALE_TOKEN="123...456"
+```
+
+For 3scale 2.8 installed on-premises, there is a default token that you can use if you wish.
+
+```sh
+export THREESCALE_TOKEN="$(oc get secret system-seed -o go-template --template='{{.data.ADMIN_ACCESS_TOKEN|base64decode}}')"
+```
+
+Fetch the cleanup playbook.
+
+```sh
+curl -Lo cleanup.yaml https://www.itix.fr/blog/cleanup-playbook-3scale/cleanup.yaml
+```
+
+## Cleanup 3scale
+
+The cleanup playbook uses the environment variables set previously to connect to the 3scale Admin Portal and get a list of the Products, Backends and ActiveDocs objects that makes up a 3scale service.
+This list is filtered to exclude the default service **api** (*Echo API*).
+The list is then filtered using the **systemname_filter** parameter to include only Products, Backends and ActiveDocs that have the given string in their system_name.
+
+Then all the matching Products, Backends and ActiveDocs are removed.
+
+For instance, to remove all objects related to the **dev_library_1** and **prod_library_1** services, you could run the playbook like this:
+
+```sh
+ansible-playbook cleanup.yaml -e systemname_filter=library
+```
+
+And to remove the **dev_library_1** and **dev_petstore_1** services, you could run the playbook like this:
+
+```sh
+ansible-playbook cleanup.yaml -e systemname_filter=dev_
+```
+
+## Conclusion
+
+This article explained how to cleanup a 3scale tenant using Ansible, by deleting all *Products*, *Backends* and *ActiveDocs* matching a given criterion.
+Now, you can reset your development environment or demo environment easily!
