f5-declarative-onboarding error 422

leo_uribe · ‎02-May-2023

Recieving the following error when trying to deploy an AWS BIGIP instance using a Terraform templatefile() function to pass variables to cloud-init template file,

tmos_do_only_wait - DEBUG - f5-declarative-onboarding error 422 - {u'message': u'request failed with null exception', u'code': 422, u'referer': u'Unknown', u'restOperationId': 6674184, u'kind': u':resterrorresponse'}

This errors occurs after the icontrollx packages (DO, AS3) are installed. When I use static values along with the file() function in the user_data argument the BIGIP has no issues accepting the configuration. I've verified my configs and compared it to examples provided in github.com/F5Networks/terraform-aws-bigip-module with no success.

Code below

Maybe then better contact support as I see a lot of 422 errors but for AS3 not DO, so it could be something new.

Hi @leo_uribe - have you taken a look at the resources around error 422 over on myf5.com? That may help you resolve the issue before someone from the community has a chance to jump in with a solution.

leo_uribe · ‎08-May-2023

Hi Leslie,

Yes, I have looked with no success. The closest issue I found was this, https://clouddocs.f5.com/products/extensions/f5-appsvcs-extension/latest/userguide/best-practices.ht... but this is specific to AS3 and we don't have any "traceResponse" set in your DO declarations.

Nikoolayy1 · ‎09-May-2023

This could be terraform issue as you said that in some cases you push the DO.

Have you tried ansible?

https://clouddocs.f5.com/products/orchestration/ansible/devel/f5_bigip/modules_2_0/bigip_do_deploy_m...

You can replace the file lookup with template lookup and the template can have variables and not be static as a file.

https://docs.ansible.com/ansible/latest/collections/ansible/builtin/template_lookup.html

Also shouldn't templatefile() souldn't it have a destination file option that will be created and then you can use the destination file?

https://www.cloudbolt.io/terraform-best-practices/terraform-template/

Maybe also test depends-on option as the terraform resources to depend on the datasource as to be triggered after it.

https://developer.hashicorp.com/terraform/language/meta-arguments/depends_on

leo_uribe · ‎09-May-2023

We would like to stick with Terraform as we plan on managing all of the app services using Terraform aswell. The odd part is the rendered output (below) from Terraform looks to be accurate. The destination file isn't required since we are passing this to AWS cloud-init agent via the "user_data" argument.

Maybe then better contact support as I see a lot of 422 errors but for AS3 not DO, so it could be something new.

I forgot to add that except a support case you can open a bug/issue in https://github.com/F5Networks/f5-declarative-onboarding/issues as for example:

https://github.com/F5Networks/f5-telemetry-streaming/issues/83

https://github.com/F5Networks/f5-appsvcs-extension/issues/338

Also review some as3 errors that may help indicate what the DO is seeing:
