I’m having an issue with the infoblox DNS proxy. When I go to create a host, I see it trying to create a record, but I get back the error:
Create IPv4 DNS record for doug-alred.example.com task failed with the following error: ERF12-2357 [ProxyAPI::ProxyException]: Unable to set DNS entry ([RestClient::Exceptions::ReadTimeout]: Timed out reading data from server) for proxy https://foreman.example.com:9090/dns
However, I do see that the record gets created inside of the Infoblox. If I set the Smart Proxy to HTTP mode and run a tcpdump, I can see the request and response headers:
Well, this appears to be a bug in foreman where responses without a body attempt to parse a non-existent body and error out. While that is RFC compliant for JSON, there should probably be some sort of content returned in the body by the smart-proxy, but I’m not sure how to make it do that…
While it does create an A record, it should be creating a Host record in Infoblox, so that PTR can be automatically configured.
This error occurs due to timeout, because it’s not getting data returned, and returns you back to the host creation screen:
Create IPv4 DNS record for dev-testvm080 task failed with the following error: ERF12-2357 [ProxyAPI::ProxyException]: Unable to set DNS entry ([RestClient::RequestTimeout]: Request Timeout) for proxy http://foreman-proxy:8443/dns
The process by which Foreman is deploying the system is blocked by this DNS failure, ultimately DNS should just be a warning and not interrupt the users deployment, they can always manually add DNS if necessary:
completed - Set up compute instance dev-testvm080
completed - Query instance details for dev-testvm080
completed - Create DHCP Settings for dev-testvm080
running - Create IPv4 DNS record for dev-testvm080
pending - Deploy TFTP PXEGrub2 config for dev-testvm080
pending - Deploy TFTP PXELinux config for dev-testvm080
pending - Deploy TFTP PXEGrub config for dev-testvm080
pending - Fetch TFTP boot files for dev-testvm080
According to the docs, there should be no functional difference between those two. If read_timeout is not set, it will be set to the timeout value and if neither is set this will default to 60 seconds.
After the change, did you restart the httpd and foreman services? I found I needed to restart these to apply the change.
The version shouldn’t matter, but for what it is worth, I am on 1.16. It still took a very long time for it to work, so give it a good while, so if you bailed out without waiting a full 60 seconds after setting timeout to 0, try that again and make sure to be patient. It will still take a very long time to creation to finish.
With read_timeout, the cursor spins as if busy, and hangs on the DNS creation part, then after 60 seconds I get:
Create IPv4 DNS record for dev-testvm087.mydomain.net task failed with the following error: ERF12-2357 [ProxyAPI::ProxyException]: Unable to set DNS entry ([RestClient::RequestTimeout]: Request Timeout) for proxy http://foreman-proxy.mydomain.net:8443/dns
With timeout value, instead, it gets to DNS creation part, and cursor is not busy, it sits there forever…no updates on the screen, nothing. I’ve been waiting 15 minutes now.
In both cases, the DNS A record gets created if dhcp_infoblox.yml option is set to fixedaddress, or it will create a host record if option set to host.
Hello, I somehow managed to miss this thread, then my review of your patch was a bit offtopic. Sorry about that.
Two of our customers ran into this issue, I am unable to reproduce however after carefully reviewing Infoblox DNS module codebase, I believe that return value from the module which comes from Faraday gem used in Infoblox gem can cause Webrick to return Content-Length either incorrectly or something else.
I created a patch which fixes the return value according to the contract, I hope this helps. Get back to me if you can confirm:
I closed some of your reports, feel free to reopen them if you feel it’s still valid. Thanks!
