./deploy.sh not working on gitlab ci

Question

My problem is the bash script I created got this error "/bin/sh: eval: line 88: ./deploy.sh: not found" on gitlab. Below is my sample script .gitlab-ci.yml.

I suspect that gitlab ci is not supporting bash script.

image: docker:latest

variables:
  IMAGE_NAME: registry.gitlab.com/$PROJECT_OWNER/$PROJECT_NAME
  DOCKER_DRIVER: overlay

services:
  - docker:dind

stages:
  - deploy

before_script:
 - docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.com
 - docker pull $IMAGE_NAME:$CI_BUILD_REF_NAME || true

production-deploy:
  stage: deploy
  only:
    - master@$PROJECT_OWNER/$PROJECT_NAME
  script:
    - echo "$PRODUCTION_DOCKER_FILE" > Dockerfile
    - docker build --cache-from $IMAGE_NAME:$CI_BUILD_REF_NAME -t $IMAGE_NAME:$CI_BUILD_REF_NAME .
    - docker push $IMAGE_NAME:$CI_BUILD_REF_NAME
    - echo "$PEM_FILE" > deploy.pem
    - echo "$PRODUCTION_DEPLOY" > deploy.sh
    - chmod 600 deploy.pem
    - chmod 700 deploy.sh
    - ./deploy.sh
  environment:
    name: production
    url: https://www.example.com

And this also my deploy.sh.

#!/bin/bash

ssh -o StrictHostKeyChecking=no -i deploy.pem ec2-user@targetIPAddress << 'ENDSSH'
 // command goes here
ENDSSH

All I want is to execute deploy.sh after docker push but unfortunately got this error about /bin/bash thingy.

I really need your help guys. I will be thankful if you can solve my problem about gitlab ci bash script got error "/bin/sh: eval: line 88: ./deploy.sh: not found".

This is probably related to the fact you are using Docker-in-Docker (docker:dind). Your deploy.sh is requesting /bin/bash as the script executor which is NOT present in that image.

You can test this locally on your computer with Docker:

docker run --rm -it docker:dind bash

It will report an error. So rewrite the first line of deploy.sh to

#!/bin/sh

After fixing that you will run into the problem that the previous answer is addressing: ssh is not installed either. You will need to fix that too!
