Icinga2 Service fails when a service is created via the API for a host that doesn't exist about icinga2

Icinga2 should error and not add the service causing icinga2 to fail.

What exactly do you mean by fail?

{"results":[{"code":500.0,"errors":["Error: Validation failed for object 'hostname.com!ssh' of type 'Service'; Attribute 'host_name': Object 'hostname.com' of type 'Host' does not exist.\nLocation: in /var/lib/icinga2/api/packages/_api/localhost-1495214738-1/conf.d/services/hostname.com!ssh.conf: 6:2-6:37"],"status":"Object could not be created."}]

That looks like an error you'll receive as an API response when attempting to create a service on a non-existing host. What behavior would you expect instead?

That is the error I received on an older version of icinga2 (icinga2 - The Icinga 2 network monitoring daemon (version: r2.10.5-1)). I expected the new version to behave the same.

So what exactly is the behavior with 2.14.2? I'm missing a description of that behavior, that's probably why I overlooked that you wrote this under "expected behavior".

You should be able to recreate the bug if you run the following 2 commands:

1. Create a host via the API to a hostgroup that does not exist
   curl -k -u user:password -X PUT 'https://localhost:5665/v1/objects/hosts/hostname1' -H 'Content-Type: application/json' -H 'Accept: application/json' -d '{"attrs":{"groups":["NoGroup"],"display_name":"hostname1","vars":{"host_name":"hostname1"}}, "templates":["generic-host"]}'

{"results":[{"code":500,"errors":["Error: Validation failed for object 'hostname1' of type 'Host'; Attribute 'groups': Object 'NoGroup' of type 'HostGroup' does not exist.\nLocation: in /var/lib/icinga2/api/packages/_api/e55a066a-19ab-4f1a-aa62-b2304fb5d858/conf.d/hosts/hostname1.conf: 5:2-5:23"],"status":"Object could not be

2. Create a service on the host above hostname1 even though it is not in icinga2
   curl -k -u user:password -X PUT 'https://localhost:5665/v1/objects/services/hostname1!ssh' -H 'Content-Type: application/json' -H 'Accept: application/json' -d '{"templates":["generic-service"],"attrs":{"check_command":"ssh","display_name":"SSH"}}'
   curl: (56) OpenSSL SSL_read: error:0A000126:SSL routines::unexpected eof while reading, errno 0

The service file is created in icinga2 even though host does not exist. This causes the icinga2 service to fail.
