help request: How to customize the log file path in apisix-go-plugin-runner

[ZChengjin]

Description

As the documentation says I modified the LogOutput of runner.RunnerConfig{} by modifying LogFilePath, but no matter what path I modify LogFilePath to, the log of go-plugin will be printed in apisix_log/error.log in the end.So I want to know How can I customize the log file path in apisix-go-plugin-runner.Thanks

@ZChengjin Hi, can you give me your code? I will check for you.

const (
	Dev  RunMode = iota // Development
	Prod                // Product
	Prof                // Profile

	ProfileFilePath = "./logs/profile."
	LogFilePath     = "../apisix_log/test.log"  //i just modified this
)

I just modified the LogFilePath in apisix-go-plugin-runner/cmd/go-runner/main.go

Are you sure this path exists? Are there any failed to open log... related logs in the apisix log? Can you see the go-runner log if you don't make any changes?

i have the same problem

go-runner is started in dev mode by default, and the log will be output in stdout. When go-runner is hosted in apisix, the log will be output in error.log.
You can use go-runner run -m prod to change the run mode of go-runner so that you can see individual log files. In apisix, you can use the following configuration:

ext-plugin:
   cmd: ["/path-to-your/go-runner/apisix-go-runner", "run", "-m", "prod"]

We will supplement the documentation on this.
