Problem:
When I try to connect from my local machine to a Redis VM hosted on Google Cloud, the connection is refused.
QUESTION: How can I connect to Redis installed on a private VM in GCP after successfully connecting to the VPC via a VPN?
Setup:
- VM hosted in Google Cloud without public IP
- Redis installed on VM by deploying the VM using the Bitnami package from GCP Marketplace
- Firewall rule added to GCP targeting my VM, allowing TCP ingress traffic on port 6379 for all IP ranges
- VPN setup using OpenVPN to tunnel into GCP VPC from local machine (Windows)
What I know:
- Redis is running... if I SSH into my VM and run
redis-cli, everything works as expected
- VPN is working... from my local machine, I can successfully
ping my VM when connected to the VPN
- Redis config comments out the binding to
127.0.0.0 to (theoretically) open it up to all bindings, after which I restarted Redis on my VM (I think)
- The password I'm using is correct
What doesn't work:
StackExchange.Redis:
var redis = ConnectionMultiplexer.Connect("my.ip.to.vm", config =>
{
config.Password = "my-redis-password";
});
Command Line from Local Machine (using redis-cli npm package):
rdcli -h my.ip.to.vm -a my-redis-password
Recap
- What am I missing?
