I have been trying a few things in heat on Juno over the last few days, and thanks to larsks on IRC, I managed to get really far. I have encountered 2 problems
1) The package heat-cfntools is no longer available in either of the rdo repository or epel for el7, It was available for el6. How best can we get hold of this package for CentOS 7. Or in-fact do we do the cfn-signal in a different way, and we no longer need to use this command?
2) I have been trying to to give unique names/numbers to hosts that are created through the "OS::Heat::ResourceGroup" resource, this supposedly has a feature where we can use %index% to add unique numbers to any of the variables. But this fails to work with the following error.
Error parsing template file:///root/hpc.yaml while scanning for the next token
found character that cannot start any token
in "<unicode string>", line 207, column 23
, this is an amended template from that larsks pointed me to.
