[docker] ERROR: gremlin-server/gremlin-server.yaml is unreadable after any change

[Kukant]

Hi all,
I am testing Janusgraph using docker. I just run the server --detach(ed) and gremlin console directly. While loading data into the graph, I encountered timeout so I decided to edit conf/janusgraph-server.yaml evaluationTimeout. However, when I save the file and restart the server, I am getting this error message:

root@01e9cf3d39fa:/opt/janusgraph# ./bin/janusgraph-server.sh start
ERROR: gremlin-server/gremlin-server.yaml is unreadable

I then changed the timeout value to previous value and it still did not work. I tried to debug it using these steps:

1. made a copy of the original config file to conf/janusgraph-server.original.yaml
2. made my small change to the timeout in conf/janusgraph-server.yaml
3. made a diff, it showed what I expected, only change was the evaluationTimeout value.
4. got the error again.
5. reset the evaluationTimeout back to previous value.
6. diff again -> no difference found
7. got the error again :(.

Could you please help me with that? Am I using it wrong?

Also, I saw the note in the beginning of the file:

# NOTE: THIS FILE IS GENERATED VIA "update.sh"
# DO NOT EDIT IT DIRECTLY; CHANGES WILL BE OVERWRITTEN.

I could not find any script of this name.

Sounds weird indeed. If you edit the yaml file in MS Windows be sure that the Linux line endings stay in place (e.g. use notepad++).

The remark about update.sh does not make sense to me either. The changes are copied into the image during building (assuming you cloned the janusgraph-docker repo and build the image locally and run the local image).
