chmod operation not permitted using watch tag

[André F. Gadonski]

Environment info:

• KrakenD version: watch
• System info: docker

Describe what are you trying to do:
i've try to use templates (like describe here https://www.krakend.io/docs/configuration/flexible-config/), but throw an error "chmod /etc/krakend/teste.json: operation not permitted

The config file has been created, but i dont know why the container says "chmod /etc/krakend/teste.json: operation not permitted"

Commands used:

# my docker compose
  api_gateway:
    image: devopsfaith/krakend:watch
    ports:
      - 1000:8080
    environment:
      - FC_ENABLE=0
      - FC_OUT=/etc/krakend/teste.json
      - FC_SETTINGS=/etc/krakend/configuracoes
      - FC_TEMPLATES=/etc/krakend/templates
    volumes:
      - ./configuracoes/krakend:/etc/krakend/
    command: ["run", "-dc", "krakend.tmpl"]

Additional comments:

[Daniel Ortiz]

The user that generates the file is uid 1000, so looks like the mounted directory has no permission to write there as uid 1000. Try changing the path of FC_OUT to /tmp or fix the directory permissions.

Did not work. Throws another error

I meant to write the file inside /tmp:

- FC_OUT=/tmp/out.json
