I'm having a certain amount of trouble getting good info on
administration of minifi 2.
The README file says thats documentation can be found at
https://nifi.apache.org/minifi and
https://cwiki.apache.org/confluence/display/NIFI/MiNiFi
neither of which URL works.
Im assuming the real documentation is at
https://github.com/apache/nifi/blob/main/minifi/minifi-docs/src/main/markdown/System_Admin_Guide.md#config-file
But Im having some Im finding it a bit confusing.
I want to configure the keystore/truststore and sensitive prop passwords.
It appears I can configure them either in bootstrap.conf or
minifi.properties. Is either to be prefered over the other?
The documention mentions nifi.properties and config.yml. But doesnt
mention minifi.properties.
Im assuming the mentions of config.yml are leftover from minifi 1
documentation. Or does minifi 2 use it for backwards compatability.
And I assume nifi.properties has been renamed to minifi.properties and
the documentation hasnt caught up.
Actually dumping strings out of the jar files, I can find instances of
nifi.properties. But I cant find any references to minifi.properties.
However the tarball contains a minifi.properties file but not a
nifi.properties file.
So Im really not sure what is going on.

Theres now a transform-nifi command in addition to the transform-yml
command.

I had a look at the minifi toolkit.
However, it only appears to contain functionality for converting legacy
minifi config to minifi 2 config
Heres an excerpt from the minifi-tookit 2.1.0 README file
Valid commands include:
transform-yml: Transforms legacy MiNiFi flow config YAML into
MiNiFi flow config JSON
## Example
- You have an older version of MiNiFi located in
<legacy_minifi_directory>.
- You would like upgrade to the latest version of MiNiFi. You downloaded
and extracted the latest MiNiFi into <latest_minifi_directory>.
- Run the following command to migrate the flow and the bootstrap config
```
./config.sh transform-yml <legacy_minifi_directory>/conf/config.yml
<legacy_minifi_directory>/conf/bootstrap.conf
<latest_minifi_directory>/conf/flow.json.raw
<latest_minifi_directory>/conf/bootstrap.conf
```
Is there functionality somewhere to convert a nifi 2.x flow file to a
minifi 2 flow file,

Hi Robert,
Seems like the documentation has not been updated. I'm going to file
a JIRA
ticket to apply doc update about how we can import NiFi 2 exported flow
files into MiNiFi.
In a nutshell: before moving the json file into minifi, we should
convert
it with minifi toolkit. Related ticket for more details:
https://issues.apache.org/jira/browse/NIFI-12644
Regards,
Peter

Im having trouble getting code into minifi 2 from nifi 2.
The documentation here
https://github.com/apache/nifi/blob/main/minifi/minifi-docs/src/main/markdown/minifi-java-agent-quick-start.md
says
# Export the dataflow in JSON format.
# Move your new .json file to |minifi/conf|.
# Rename your .json file /flow.json.raw/.
Im using the option in nifi to "download flow definition"
However when I load that into minifi, I get an error message.
java.lang.Exception: Unable to load flow due to:
org.apache.nifi.controller.serialization.FlowSerializationException:
Could not parse flow as a VersionedDataflow
When I compare the file to the dummy flow file that ships with minifi.
The file that ships with minifi starts with
{
"encodingVersion": {
"majorVersion": 2,
"minorVersion": 0
},
But the export from nifi has
{"flowContents":{"identifier":"a2ac574c-635d-3df5-baf0-6cbf4dd5bdec",
So the 2 files dont appear to be the same format.
Is there some other method of exporting code from nifi that Im
missing?
