get permission denied when using docker in self-hosted server

HI all, I have an issue about using docker in self-hosted server I have a runner installed on ubuntu 18.04 The runner is running with svc.sh And my pipeline is using a docker The docker is already installed in the server and can run without sudo

# my pipeline
name: Go

on:
  push:
    branches: [ master ]

jobs:

  build:
    name: Build
    runs-on: self-hosted
    steps:
    
    - name: check out
      uses: actions/checkout@v2
    
    - name: Use go docker
      uses: docker://golang:1.13.9-alpine3.10

    - name: Run go
      run: go run main.go

logs

@beetlikeyg087 I found your issue while trying to fix the same problem I managed to make the action run the docker command itself by also restarting the service with:

sudo ./svc.sh stop
sudo ./svc.sh start

hope that helps

make sure you have given permission to the user that will run the github agent like so:

sudo usermod -a -G docker <USER>
