TASK [ipareplica : Install - Setup DNS] - AttributeError: 'AnsibleModuleLog' object has no attribute 'isatty'

Hi

I try to install FreeIPA on CentOS 8. All installation steps (Setup DS, Setup CA) works, except setup DNS role.

During execution TASK [ipareplica : Install - Setup DNS] I receive error:

AttributeError: 'AnsibleModuleLog' object has no attribute 'isatty'

Full Traceback:

I saw closed issue https://github.com/freeipa/ansible-freeipa/issues/117 but no solution is provided. Can you please help to solve issue?

[rjeffman]

The error is occuring inside ipalib, part of FreeIPA, it might be an issue there or on ansible-freeipa.

Can you provide CentOS and package versions? Can you provide details on the configuration you are using so that it can be reproduced?

[pavel-z1]

Hi @rjeffman

I am use CentOS Linux release 8.1.1911 (Core) with kernel 4.18.0-147.8.1.el8_1.x86_64. This is latest public CentOS 8.

Steps to reproduce issue:

1. Install FreeIPA Master server with any default parameters and enabled DNS role on master server.
2. Configure vars to enable Replica DNS role, variables should be applied to the new replica server:

   ipareplica_setup_dns: yes
   ipareplica_forwarders:
   - 8.8.8.8
   - 1.1.1.1

3. Install Replica server with enabled DNS via ansible playbook. It is important to enable ipareplica_setup_dns befor start setup replica server. Ipa replica role won't setup DNS role if IPA replica was installed previously on server.

[MannerMan]

Having the same problem trying to use these ansible roles for a FreeIPA deployment on CentOS 8!

[MannerMan]

We did a temporary try-catch patch for /usr/lib/python3.6/site-packages/ipalib/cli.py to get around this error for now;

        try:
            if sys.stdout.isatty():
                try:
                    winsize = fcntl.ioctl(sys.stdout, termios.TIOCGWINSZ,
                                        struct.pack('HHHH', 0, 0, 0, 0))
                    return struct.unpack('HHHH', winsize)[1]
                except IOError:
                    pass
        except AttributeError:
            pass
        return None

I had exactly the same issue on an updated CentOS 8. I fixed that by adding the missing isatty method to theAnsibleModuleLog class.

[Drugantibus]

Just run into this issue 2 years later. Is there any reason keeping those 3 lines from being added upstream?

[rjeffman]

I wonder why this does happen, as CentOS is used a lot on testing and I was never able to reproduce this. My guess is that this is shadowing another issue.

@Drugantibus can you provide the settings you are using to deploy the replica?

[Drugantibus]

@rjeffman This is actually on Fedora 34 ("Cloud Edition", on EC2). Here are the vars used:

ipaserver_domain: ***
ipaserver_realm: ***
ipaserver_setup_dns: true
ipaserver_forwarders: 10.0.0.2
ipaserver_reverse_zones: 0.10.in-addr.arpa
ipaserver_allow_zone_overlap: true
ipaserver_no_dnssec_validation: true

ipareplica_server: ipa01.***
ipareplica_setup_dns: true
ipareplica_setup_ca: true
ipareplica_forwarders: 10.0.0.2
ipareplica_no_dnssec_validation: true

ipaclient_mkhomedir: true
ipaclient_all_ip_addresses: true
ipaclient_ssh_trust_dns: true
ipasssd_enable_dns_updates: true

[rjeffman]

@Drugantibus can you deploy the replica using the command line, in the same environment?

[infra-monkey]

Just ran into this issue on centos stream 9 with ansible_freeipa 1.8.1 With the workaround from iiomnium it passes.

@rjeffman I can do some tests if you need someone.
