Docker + Redis - fails to run command

Question

First time trying docker with Laravel sail.

On first sail up I noticed the following error:

WARNING overcommit_memory is set to 0! Background save may fail under low memory condition

I followed instructions here to fix this issue, but I am now stuck with this error:

sh: ./init.sh: not found

My dir structure is:

e:\laravel-project
   - docker-compose.yml

e:\Docker
   $redis
      - Dockerfile
      - init.sh
      - redis.conf

My docker-compose contains:

redis:
    build:
        context: "./../../Docker/Redis"
        dockerfile: Dockerfile
    image: "redis:alpine"
    privileged: true
    command: sh -c "./init.sh"
    ports:
        - "${FORWARD_REDIS_PORT:-6379}:6379"
    volumes:
        - "sail-redis:/data"
    networks:
        - sail
    healthcheck:
        test: ["CMD", "redis-cli", "ping"]
        retries: 3
        timeout: 5s

My Dockerfile (from the link) is:

# file: docker/redis/Dockerfile
FROM redis:alpine
WORKDIR /redis
COPY redis.conf /usr/local/etc/redis/redis.conf
COPY init.sh ./
RUN chmod +x init.sh

The init.sh file contains:

echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag

sysctl -w net.core.somaxconn=512
sysctl vm.overcommit_memory=1
redis-server /usr/local/etc/redis/redis.conf --bind 0.0.0.0

The first error is not showing now which leads me to think the redis.conf file is being loaded.

redis exist with error and does not start:

exited with code 127

What have I missed on the init.sh file? Thanks!
