Creating a Linux Docker for parity on a Windows 10 machine

Question

I'm trying to run parity on Docker. My workstation is Windows 10, but the Docker is intended for a Linux machine. Right now I'm having trouble running the Docker with --base-path option, as I keep getting the following error:

Client service error: Client(Database("IO error: directory: Invalid argument"))

This is the docker command I'm running:

docker run -v /d/parity/docker:/root/.local/share/io.parity.ethereum/ -p 8180:8180 -p 8545:8545 -p 8546:8546 -p 30303:30303 -p 30303:30303/udp parity/parity:v1.7.9 --unsafe-expose --base-path /root/.local/share/io.parity.ethereum/

Does anybody has an idea?

I'm also running docker on windows 10 and had very similar problem when using parity in docker with the help of this project:

https://github.com/paritytech/parity-deploy

This creates docker compose file and configuration files for you. After starting the container I got the same error. I suspect it has to do something with the differences in the file systems between the windows and linux.

Solved it by creating the volume and mounting /parity/data (in your case /root/.local/share/io.parity.ethereum/) to that volume.

To create volume:

docker volume create myvolume

Then in compose file I've added volume:

volumes:
  myvolume:
    external: true

and in compose file in the parity container configuration replaced volume mapping

- ./data/is_authority:/parity/data

with

- myvolume:/parity/data

So with your docker run command I'd try replacing

-v /d/parity/docker:/root/.local/share/io.parity.ethereum/

with

-v myvolume:/root/.local/share/io.parity.ethereum/
