While getting a local VM managed by Vagrant to work with Ansible for provisioning, I kept getting errors like the following:
fatal: [solr] => SSH encountered an unknown error during the connection. We recommend you re-run the command using -vvvv, which will enable SSH debugging output to help diagnose the issue
[vm-name-here] : ok=0 changed=0 unreachable=1 failed=0
FATAL: no hosts matched or all hosts have already failed -- aborting
Ansible failed to complete successfully. Any error output should be
visible above. Please fix these errors and try again.
It seems that Ansible is unable to connect to the VirtualBox host via SSH because the entry for 127.0.0.1 in my ~/.ssh/known-hosts
file is set for my local computer, and not for any VMs. To work around this limitation, I created a new file, ~/.ssh/config
, with the contents:
Host 127.0.0.1
StrictHostKeyChecking no
UserKnownHostsFile=/dev/null
Now, when Ansible tries connecting during provisioning, it doesn't check the host key for localhost, and provisioning succeeds.
Comments
Thank you so much for this advise, it was really helpful!
In my case I had to add this line to get it working:
IdentitiesOnly yes
Thanks! I think this finally got it working for me.
Thank you so much! It worked for me!
For me it was also "IdentitiesOnly yes" in ~/.ssh/config that did the trick!
how do you tell ansible to use your new config file?
Thank you very much! It really works
Excellent!
