Plugin enable command is looking for .sock file in /run/docker/plugins/<docker-plugin-id> and not /run/docker/plugins

[rajulm]

I am trying to create a java plugin because of the use case that we have where we want to use some java library(which is hard to migrate in golang). Since I didn't find any helpers which are already there in github, I am trying to code from scratch!

I have made a good progress on that but I am stuck at one point where "plugin enable <plugin_name>" command is not able to find the .sock file at the desired location.

As per this document -- Plugin Discovery, sock file should be created in directory -- /run/docker/plugins. I looked at the code for "go-plugin-helpers" code as well (reference here), we are creating the .sock files in the location /run/docker/plugins/ . There are 2 things I am not sure about and which has got me confused:

1. When I try installing and enabling the sample plugins which are already developed in golang, I actually see the sock file in location /run/docker/plugins/a864dd55a0963ec5d1b501497864617be3b4b49d12a9b6f482e2d5ec72e4eb1c/jsonfile.sock and not /run/docker/plugins/jsonfile.sock. As per code, it is created as latter, then how is it creating the former. Which step is doing that in code? Am I missing something?
2. When I try to create a plugin and enable it, I am creating the .sock file in the suggested location /run/docker/plugins/ but my plugin enable command fails looking for the file in a different location Error response from daemon: dial unix /run/docker/plugins/a2b3f998d76eac6fa21d9e2963de29b1385b2244231f87a6b5a6bf05ac8ae7e9/jsonfile.sock: connect: no such file or directory

SO the questions are :

1. Why is it looking in the directory /run/docker/plugins/<docker-plugin-id> and not at the location where it is supposed to look at? Is it some configuration that I am missing?
2. How are go-helpers creating under the directory ```/run/docker/plugins/`` when I don't see any code which has any id passed and accepted?

I can share more details if someone has any pointers and can answer some questions here? Would really appreciate any help.
