Docker Remote Attach -> Breakpoints not working #75

Closed laudanum123 closed 1 year ago

laudanum123 commented 1 year ago

Hi, I am trying to attach to a running docker session. I manage to attach to the docker container using DapContinue but it tells me:

Breakpoint in file that does not exist

my dap.lua looks like this

require('dap-python').setup('/usr/local/share/miniconda3/bin/python')
table.insert(require('dap').configurations.python, {
  type = 'python',
  request = 'attach',
  name = 'Remote Python: Attach',
  port = 5678,
  host = "127.0.0.1",
  mode = "remote",
  cwd = vim.fn.getcwd(),
  pathMappings = {
    {
      localRoot = function()
        return vim.fn.input("Local code folder > ", vim.fn.getcwd(), "file")

      end,
      remoteRoot = function()
        return vim.fn.input("Container code folder > ", "/", "file")
      end,
    },
  },
})

I think it is something to with the pathes within the docker container and my local directory but I just cannot get it to work :-( the file I am trying to access is in /server in my local dir while it is in /backend in the docker. This is the logile for a attempt:

I was able to solve this issue by using the command: python -m pydebug --listen 0.0.0.0:5678 --wait-for-client app.py in the docker container and then connecting from my local system using nvim-dap. Before I was trying to get the more general command working, which allows to connect pydebug to a specific python process which is already running in the container.
