Comment 3 Gaoyun Pei 2015-04-16 04:43:38 UTC

@Jason, thanks for the detailed explanation.

After configuring my ansible hosts file with openshift_hostname and openshift_public_hostname fields, it works pretty well.

Update the bug summary to track the problem mentioned in step 4.

Comment 4 Jason DeTiberus 2015-11-18 20:11:58 UTC

Once https://github.com/openshift/openshift-ansible/pull/924 is merged, we will no longer set the hostname on systems and will not be limited by the hostname length of hostnamed anymore.

Comment 5 Gaoyun Pei 2015-11-19 09:18:10 UTC

Got the same error as https://bugzilla.redhat.com/show_bug.cgi?id=1275395#c4 mentioned when testing with this PR.

Comment 6 Brenton Leanhardt 2016-01-12 16:31:37 UTC

Now that https://github.com/openshift/openshift-ansible/pull/1165 is merged would you mind testing this to see if the error message for excessively long names is improved?

Comment 7 Gaoyun Pei 2016-01-13 06:36:32 UTC

Verify with the latest openshift-ansible master branch.

When installing with hostname more than 64 characters, ansible would abort the installation and prompt that the hostname length is invalid as below:

TASK: [openshift_common | fail ] ********************************************** 
failed: [10.66.x.x] => {"failed": true}
msg: openshift_hostname must be 64 characters or less
failed: [10.66.x.x] => {"failed": true}
msg: openshift_hostname must be 64 characters or less
