Pierre Villard commented on NIFI-15232:
---------------------------------------
I believe what you're asking for has been implemented in NIFI-14550. This is
not exposed in the UI but can be done via API calls.
> Nifi should allow connecting a ProcessGroup to an existing flow configuration
> stored in GitHub (Create from GitHub)

> Project: Apache NiFi
> Issue Type: Improvement
> Components: Flow Versioning

> h2. Problem description:
> When I start versioning a flow with the GitHubFlowRegistry client, I
> basically create a flow definition file in a folder on a GitHub branch.
> However, if I accidentally delete the versioned process group and try to
> recreate it, I cannot link to the existing file.

> This can be mitigated, if the process group above the deleted process group
> is versioned as well, since we can then roll back the changes. However, if we
> are talking about the root process group or about transporting a flow
> definition between Nifi instances, this is not possible.
> A use case is realizing a development / testing / production environment
> separation using Git Branches in GitHub with the ability to transport the
> definition between the environments using pull requests. In this case, it is
> finicky at best to do the initial configuration, since equal process groups
> have to be created and versioned on each instance and conflicts must be
> resolved when initially merging changes between branches.
> h2. Proposed solution:
> The ability to simply connect an empty process group (or a process group
> during creation) to an existing versioned flow file on GitHub (defined by the
> same flow name in the API, possibly similar to how a process group can be
> created from a JSON flow file upload) would be great for the user experience
> with GitHub versioning.
> It also allows for restoring a NiFi instance configuration from GitHub in
> case of server changes or missing backups.
