I'm new to Traefik. I'm trying to develop a plugin and "connect" it to my webserver using Docker Compose. I use docker compose for development. When I try to run the Docker Compose I encountered this error:

```bash
/dev/echo-docker-compose $ docker-compose up --build

```

I think I can conclude that the cause of this error is that it can't find the `.traefik.yml` file which is quite obvious. But, I already have the file in that directory.

This is my full directory structure

```auto
dev/plugins-local/
    └── src
        └── github.com
            └── traefik
                └── traefik-plugin-example
                    ├── plugin.go
                    ├── plugin_test.go
                    ├── .traefik.yml
                    ├── go.mod
                    ├── Dockerfile
                    ├── Makefile

    ├── rules-plugin.go
dev/echo-docker-compose/
    └── docker-compose.yml
    └── cmd
        └── ....

```

For some reasons, I think Docker Compose can't read `.traefik.yml`. But, it's also the same case when I try to run `./traefik --configfile traefik-plugin.yml` from `dev/plugins-local`. It also throws the same error where it can't read the `.traefik.yml`.

Anyone knows how to fix this problem?

This is the relevant codes:

Hello @panah,

It might be due to a missing volume on docker compose to add the local plugin inside your docker container.

Hope it helps

Thanks. Tried adding it to the volumes, but now it gives a different error.

```bash
failed to decode the plugin manifest plugins-local/src/github.com/usergithub/traefik-plugin-example/.traefik.yml: yaml: input error: read plugins-local/src/github.com/usergithub/traefik-plugin-example/.traefik.yml: is a directory

```

It cant decode the manifest because it thinks it's a directory. Any solution?

I think you get mixed up in volumes, your volume should be:

```yaml
services:
  traefik:
    ...
    volumes:
      ...
      - "./dev/plugins-local/:/plugins-local/"

```

You need to have the plugin source code in your docker container.

This is due to mapping a directory as a file in a volume.

Thanks! I'm gonna try playing around with it. I've gotta admit I'm not really great with docker. I thought it was Traefik's issue.
