Ansible - Bricking freshly installed vcmp guests with ansible
Hello fellow F5 admins, currently I try to establisheda workflow, where new vcmp guests are created and configured with a standard basic config (and even building a HA setup). The creation part is working, but here begin the problems: tl;dr Question: What is the properway to bootstrap a freshly installed vcmp guests(or appliance), when you are forced to change the default passwords on 1st login, without doing it by hand? The only solution I found (link below) will lock me out of the system forever. Long Version: Freshly installed systems enforce a password change for admin user on 1st access. This password change cannot be accomplished with the standard ansible module "bigip_user". If you try, you will get an error telling you, password has expired and it has to be changed. I then found an article about the security password policy and how one is supposed to change the password with ansible (https://techdocs.f5.com/en-us/bigip-14-0-0/big-ip-system-secure-password-policy/secure-password-policy-chapter-title.html) So I gave it a try and the password was changed "a" password, but not the one provided by the playbook variable. Neither GUI nor SSH or REST login will work. I am locked out. Befor you ask: yes the password in ansible-vault style is correct, because it is used to create the guest on the vcmp hosts. Here is my playbook: --- - name: Test vCMP-Guest hosts: vcmp_guests gather_facts: false vars: f5_api_admin_user: admin f5_api_admin_password: !vault | $ANSIBLE_VAULT;1.1;AES256 35613438373864653838386266616364666366363332646635303036343266646664656333643932 6462363934306365636265313038376436353032303330370a656434643837343165316333393932 66616133376433303136366664303563373034353630656531663864323433663166653539303937 3937646663613064390a663631623733376339353735633362633139383635386661376137653434 6237 bigip_provider: server: "{{ ansible_host }}" server_port: 443 user: "{{ f5_api_admin_user }}" password: "{{ f5_api_admin_password }}" validate_certs: false transport: rest tasks: - name: Set admin Password uri: url: "https://{{ ansible_host }}/mgmt/shared/authz/users/admin" method: PATCH body: '{"oldPassword":"admin","password":"{{ f5_api_admin_password }}"}' body_format: json validate_certs: false force_basic_auth: true user: admin password: admin headers: Content-Type: "application/json" register: result delegate_to: localhost - name: Debug ansible.builtin.debug: var: result - name: Try to get system info f5networks.f5_modules.bigip_device_info: gather_subset: - system-info provider: "{{ bigip_provider }}" register: output delegate_to: localhost - name: Debug ansible.builtin.debug: var: output The Output of the the passwordreset task look fine to me: TASK [Debug] ******************************************************************************************************************************************************************************** task path: ~/guest-playbook.yml:47 ok: [test-guest] => { "result": { "cache_control": "no-store, no-cache, must-revalidate", "changed": false, "connection": "close", "content_length": "330", "content_security_policy": "default-src 'self' 'unsafe-inline' 'unsafe-eval' data: blob:; img-src 'self' data: http://127.4.1.1 http://127.4.2.1", "content_type": "application/json; charset=UTF-8", "cookies": {}, "cookies_string": "", "date": "Fri, 29 Sep 2023 11:48:50 GMT", "elapsed": 0, "expires": "-1", "failed": false, "json": { "displayName": "Admin User", "encryptedPassword": "<removed>", "generation": 0, "kind": "shared:authz:users:usersworkerstate", "lastUpdateMicros": 0, "name": "VALUE_SPECIFIED_IN_NO_LOG_PARAMETER", "selfLink": "https://localhost/mgmt/shared/authz/users/********", "shell": "/sbin/nologin" }, "msg": "OK (330 bytes)", "pragma": "no-cache", "redirected": false, "server": "Jetty(9.2.22.v20170606)", "status": 200, "strict_transport_security": "max-age=16070400; includeSubDomains", "url": "https://<removed>/mgmt/shared/authz/users/********", "x_content_type_options": "nosniff", "x_frame_options": "SAMEORIGIN", "x_xss_protection": "1; mode=block" The next task, will already fail with a "unauthorized" message. From now on, I cannot access the system any more, and believe me, I tried a lot. One interesting Thing: When I don't use a ansible-vault encrypted password and instead set the variable directly to the string, login is possible, BUT only to the GUI. I cannot do rest api calls with this password. When I change the admin password again (from within GUI), I can however use rest api again. When I change it back to the original one, api calls will fail. There is one difference I noticedin /var/log/audit in the case, when I set the password as clear-text: User authentication is logged like this and the api request fails: AUDIT - user admin - RAW: httpd(pam_audit): User=admin tty=(unknown) After setting a new password within the GUI oder tmsh and running the same api request, audit messaged changed like this and the request is successfull: [...] AUDIT - user admin - RAW: rest(pam_audit): user=admin(admin)[...] When I now change the password back to the previous one, api request fails again [...]AUDIT - user admin - RAW: httpd(pam_audit): User=admin tty=(unknown)[...] What on earth is going on? How is one supposed to bootstrap a vcmp guest from ground up without manually interaction for setting passwords and stuff? Any usefull advice isthoroughly appreciate.
