Golang Remote Debug and Docker debug

Sometimes I need to remotely debug Golang programs, such as the code we write on MacOS, but sometimes run on Linux, so we need to remotely debug the code running on the Linux system. Another scenario is that we can package the goalng into a Docker image, and the code can be debugged in a container. Take Goland as an example.

Remote Debug

Remote debugging Golang code requires that you follow delve on the remote machine where the code is running, and then run the program that you want to debug with delve.

• Compile

   export CGO_ENABLED=0 GOOS=linux GOARCH=amd64   go build -gcflags='all -N -l' main.go

• Install Delve

• Delve running the program

 dlv --listen=:2345 --headless=true --api-version=2 exec ./main

• Goland Setting up Remote Debug
  Host IP port for remote host is the port that was just DLV set

• Debug
  Then debug the program on the remote host just as you would debug local code
