As a total newb, what are my options for getting to the point where I can test simple rest calls against BigFix server?
Any official of community supported
cloud hosted instances?
I guess I don’t know what official community supported is, but AFAIK there are no docker images or VMs available for download of the BigFix server. There have been some half-hearted build scripts, but I don’t recall their status. By cloud hosted instances, do you mean is the bigfix server supported in the cloud? If so, the answer is yes. If you are asking if there are any free-use demo cloud instances, then I don’t think so.
If none of the above, using the installer with all of its dependencies (sql server, etc…) must be the only option. And if so, is this 2013 walkthrough the right one to follow:
That might be a good guide, but I would use the official one via IBM: https://www.ibm.com/support/knowledgecenter/SSQL82_9.5.0/com.ibm.bigfix.doc/Platform/Installation/c_audience.html
