I think this is a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1353920 ? Nope... it's not the same issue. If the value is to similar to the key, this breaks. The other case solves one specific corner case but look at this one:
1) When the first compute his deployed, it replaces all the strings in that array so
HostnameMap:
whatever-CTLR0: whatever-CTLR0-wa1614
whatever-CTLR1: whatever-CTLR1-wa1514
whatever-CTLR2: whatever-CTLR2-wa0112
whatever-COMP0: whatever-COMP0-wa0001
whatever-COMP1: whatever-COMP1-wa1101
whatever-COMP2: whatever-COMP2-wa0002
whatever-COMP3: whatever-COMP3-wa1102
whatever-COMP4: whatever-COMP4-wa0003
whatever-COMP5: whatever-COMP5-wa1103
whatever-COMP6: whatever-COMP6-wa0004
whatever-COMP7: whatever-COMP7-wa1104
whatever-COMP8: whatever-COMP8-wa0005
whatever-COMP9: whatever-COMP9-wa1105
whatever-COMP10: whatever-COMP10-wa0006
whatever-COMP11: whatever-COMP11-wa1106
whatever-COMP12: whatever-COMP12-wa0007
becomes:
HostnameMap:
whatever-CTLR0: whatever-CTLR0-wa1614
whatever-CTLR1: whatever-CTLR1-wa1514
whatever-CTLR2: whatever-CTLR2-wa0112
whatever-COMP0: whatever-COMP0-wa0001
whatever-COMP1: whatever-COMP1-wa1101
whatever-COMP2: whatever-COMP2-wa0002
whatever-COMP3: whatever-COMP3-wa1102
whatever-COMP4: whatever-COMP4-wa0003
whatever-COMP5: whatever-COMP5-wa1103
whatever-COMP6: whatever-COMP6-wa0004
whatever-COMP7: whatever-COMP7-wa1104
whatever-COMP8: whatever-COMP8-wa0005
whatever-COMP9: whatever-COMP9-wa1105
whatever-COMP10: whatever-COMP1-wa11010-wa0006
whatever-COMP11: whatever-COMP1-wa11011-wa1106
whatever-COMP12: whatever-COMP1-wa11012-wa0007
Yeah, this is fixed in OSP10 by https://review.openstack.org/#/c/355583/ |
Description of problem: When using HostnameMap with more than 9 computes, hostnames are not properly set and this is due to the use of str_replace in /usr/share/openstack-tripleo-heat-templates/puppet/compute.yaml: NovaCompute: type: OS::Nova::Server properties: image: {get_param: Image} image_update_policy: get_param: ImageUpdatePolicy flavor: {get_param: Flavor} key_name: {get_param: KeyName} networks: - network: ctlplane user_data_format: SOFTWARE_CONFIG user_data: {get_resource: UserData} name: str_replace: template: {get_param: Hostname} params: {get_param: HostnameMap} So as soon as you hit compute 10-19, it will always replace the first part of the string with the first node in the HostnameMap... The effect here is that you end up with 0-9 at the end of the string instead of having the proper hostname in the HostnameMap.
