same as: #137?

Almost same, it caused by apisix runtime will find "conf" sub-folder in current execution folder after attach to process debugging.
That means the actor has to execute "apisix start " under %APISIHOME% ( i.e. /usr/local/apisix ), otherwise, apisix runtime will find conf sub-folder. if "conf" folder doesn't exist. the error will popup.

therefore , recommend that

  1. no matter where "apisix start" executes, it automatically create sock file under static folder such as %APISIX_HOME%/conf
  2. add a mandatory configuration section for "ext-plugin" to let user set which folder to create sock file. thx

I think APISIX already does this?

Does this mean that if you run apisix start in another folder, like /tmp, then a sock file will be created under /tmp/conf?

zhlu001 commented 1 year ago

No, config is not set for ext-plugin : path_to_test: /tmp/runner.sock (this mode is working). We set it as ext-plugin: cmd : ['jar','-jar','/path/to/runner.jar']

when execute "apisix start " while there is no conf folder in some folder, this error will popup. i.e. executed "apisx start" under /opt. apisix run time will find /opt/conf/apisix-{d}.sock. but definitionally, there is no conf folder. when execute "apisix start " under other-folder. apisix runtime will find other-folder/conf/apisix-{d}.sock.

you could repo this error but use above information. that's why we recommend that

  1. no matter where "apisix start" executes, it automatically create sock file under static folder such as %APISIX_HOME%/conf
  2. add a mandatory configuration section for "ext-plugin" to let user set which folder to create sock file. thx

I think we can do this: in APISIX ext-plugin, when creating a sock file, first check if the conf folder exists, and create it if it doesn't.

zhlu001 commented 1 year ago

Great, but it would be better to creating a sock file in a unified folder such %APISIX_Home%/conf. because user may run "apisix start" in any folder of system.

Thank you.
