How to automatically deploy to VPS in Docker from Gitlab CI

Question

I'm trying to deploy to Docker in my VPS everytime a new commit is made in my project in Gitlab. But I'm having an issue doing that.

I tried to install sshpass and then scp folder and files. But it's saying:

sshpass: Failed to run command: No such file or directory.

The folder and files I'm trying to get from build stage, so I dont have to build again my app.

Here's my .gitlab-ci.yml file:

image: node:9.6.1

cache:
  paths:
    - node_modules/
    - build/
    - docker-compose.yml
    - Dockerfile
    - nginx.conf

stages:
  - build
  - test
  - dockerize

build-stage:
  stage: build
  script:
    - npm install
    - CI=false npm run build
  artifacts:
    paths:
      - build/
      - docker-compose.yml
      - nginx.conf

test-stage:
  stage: test
  script:
    - npm install
    - CI=false npm run test

dockerize-stage:
  stage: dockerize
  image: tmaier/docker-compose:latest
  services:
    - docker:dind
  dependencies:
    - build-stage
  tags:
    - docker  
  script:
    - apk update && apk add sshpass
    - sshpass -V
    - export SSHPASS=$USER_PASS
    - ls -la
    - sshpass -e ssh -o stricthostkeychecking=no root@ip:/home mkdir new-super-viva
    - sshpass -e scp -o stricthostkeychecking=no -r build user@ip:/home/new-folder
    - sshpass -e scp -o stricthostkeychecking=no -r docker-compose.yml user@ip:/home/new-folder
    - sshpass -e scp -o stricthostkeychecking=no -r nginx.conf user@ip:/home/new-folder
    - sshpass -e ssh -o stricthostkeychecking=no user@ip:/home/new-folder docker-compose up --build

Here's the actual output from Gitlab CI:

$ sshpass -V

Is there any way that I can copy the build folder, docker-compose.yml and nginx.conf files from build-stage to dockerize-stage and then pass it with sshpassto VPS? It doesnt even working to create folder with mkdir. I also tried to create folder manually and then remove this command from .gitlab-ci.yml but still the same output.

Just so you know I added that USER_PASS in: https://gitlab.com/user/project/settings/ci_cd in environment variables and let it non-protected
