Redis server

1

Hi, I’m trying to deploy Redis with redis_exporter. When I check the monitoring, it shows redis_up 1. However, when I try to connect using redis-cli, my connection is denied. What could be the problem here? I tested everything locally, and it works fine.

here’s my fly.toml

primary_region = 'hkg'

[http_service]
  internal_port = 9092
  force_https = true

[[services]]
  internal_port = 6379
  protocol = "tcp"
  [[services.ports]]
    port = 6379


[[vm]]
  size = 'shared-cpu-1x'
  memory = "512mb"

here’s my dockerfile

FROM redis:6.2.6

RUN apt-get update && \
    apt-get install -y procps wget && \
    rm -rf /var/lib/apt/lists/*

RUN wget https://github.com/oliver006/redis_exporter/releases/download/v1.43.0/redis_exporter-v1.43.0.linux-amd64.tar.gz && \
    tar xzf redis_exporter-v1.43.0.linux-amd64.tar.gz && \
    mv redis_exporter-v1.43.0.linux-amd64/redis_exporter /usr/local/bin/ && \
    rm -rf redis_exporter-v1.43.0.linux-amd64*

ADD redis.conf /usr/local/etc/redis/redis.conf
ADD start-redis-server.sh /usr/bin/
RUN chmod +x /usr/bin/start-redis-server.sh

EXPOSE 6379 9092

CMD ["start-redis-server.sh"]

and here’s the start-redis-server.sh

#!/bin/sh
sysctl vm.overcommit_memory=1
sysctl net.core.somaxconn=1024

# redis-server /usr/local/etc/redis/redis.conf --requirepass $REDIS_PASSWORD
redis-server /usr/local/etc/redis/redis.conf & \
    redis_exporter --redis.addr=redis://0.0.0.0:6379 --redis.password "your_password_here" --web.listen-address=:9092

and the last logs are
