We had always used hammer host update --parameters in previous versions because I interpreted set-parameter as creating a new parameter rather than just changing the value of already set parameter. It was working correctly in Foreman 1.22. The behavior is odd in Foreman 1.23 because hammer host update --parameters now overwrites any prior changes, and returns the parameter back to the default.
I tried your suggestion, but after several experiments, I found that it only works for parameters that were already overriding the default global parameter. It does not work for any parameter that was not already overriding the default.
$ hammer host set-parameter --name 'tla' --parameter-type 'string' --value 'syseng' --host sysenga05a.a.example.us
Could not set host parameter:
Internal Server Error: the server was unable to finish the request. This may be caused by unavailability of some required service, incorrect API call or a server-side bug. There may be more information in the server's logs.
$ hammer host set-parameter --name 'patch_time' --parameter-type 'string' --value '1100' --host sysenga05a.a.example.us
Could not set host parameter:
Internal Server Error: the server was unable to finish the request. This may be caused by unavailability of some required service, incorrect API call or a server-side bug. There may be more information in the server's logs.
$ hammer host set-parameter --name 'patch_day' --parameter-type 'string' --value 'wednesday' --host sysenga05a.a.example.us
Could not set host parameter:
Internal Server Error: the server was unable to finish the request. This may be caused by unavailability of some required service, incorrect API call or a server-side bug. There may be more information in the server's logs.
This is the only parameter that works with your method (and did not overwrite prior changes):
$ hammer host set-parameter --name 'node_type' --parameter-type 'string' --value 'db' --host sysenga05a.a.example.us
Host parameter updated
$ hammer host set-parameter --name 'node_type' --parameter-type 'string' --value 'app' --host sysenga05a.a.example.us
Host parameter updated
Logs for one parameter that works:
