Ansible claims host unreachable

[ToontjeM]

fatal: [myhost.ddns.net]: UNREACHABLE! => changed=false msg: 'Failed to create temporary directory. In some cases, you may have been able to authenticate and did not have permissions on the target directory. Consider changing the remote tmp path in ansible.cfg to a path rooted in "/tmp", for more error information use -vvv.

I created a host on ddns.net called myhost.ddns.net
added this host to inventory/hosts as
[matrix_servers] myhost.ddns.net ansible_host=myinternalIP ansible_ssh_user=myuser ansible_connection=community.docker.nsenter
Forwarded SSH on the firewall to redirect to myinternalIP. Tried with myexternalIP and myddnshostname as well).
SSH from outside to the ddns host gives me a proper response:
√ [centos7] ~ ssh [email protected] The authenticity of host 'myhost.ddns.net (myexternalIP)' can't be established. ECDSA key fingerprint is SHA256:G1j99whatever. ECDSA key fingerprint is MD5:48:35:7e:whatever Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'myhos.ddns.net,myexternalIP' (ECDSA) to the list of known hosts. [email protected]'s password: Welcome to Ubuntu 22.04.2 LTS (GNU/Linux 5.15.0-75-generic x86_64)

Also from inside the container i can ping myhost.ddns.net and responds with the correct external IP address.

What am i doing wrong here?

This is not the issue. As you can see in the log, there is clearly a message “Failed to create directory”

Misread, #22 (comment). Doing this will run the container in a privileged mode that'll allow it to do the directory stuff
