After creating a new Google Memorystore of type Redis Standard, I'm allocated an internal IP address of 10.0.0.#. However, none of my compute instances in the project can access it (telnet fails).
Also unable to access it via the Cloud Shell.
From the documentation: "You can connect to the Redis instance from any Compute Engine VM instance located within the same project, region and network as the Redis instance." I don't see anything to suggest that cross-region is possible.

I am wanting to connect my Cloud Run app to Postgres Cloud SQL instance without assigning the instance a public IP. Seems like the only way to do this is with a Serverless VPC Access connector.
The docs indicate that the Serverless VPC Access connector is billed as 1 e2-micro instance per 100Mbps. Does this indicate that the connector is simply a single e2-micro VM? Is there any redundancy/automated-failover configured behind the scenes?
I can't find any SLA for the Serverless VPC Access and am worried that it could be a single point of failure for my app that brings down all DB connections.
The VPC Access Connector is a Compute Engine instance privately managed by Google Cloud. You are billed per 100Mbit of capacity. The instance size can scale up but not back down. Is this a single point of failure, yes but the service will auto recover. Fault tolerance, recovery time and SLA are not published (AFAIK).
Additional information:
The images for the VPC Access Connector instances are from the project serverless-vpc-access-image.
These instances use RFC1918 addresses that cannot overlap your VPCs.
These instances are basically NAT Gateways and require IP forwarding be allowed constraints/compute.vmCanIPForward.
I have a service which runs on Cloud Run, and a MYSQL, MongoDB databases on Compute Engine. Currently, I'm using public IP for connect between them, I want to use internal IP for improving performance, but i cant find solution for this problem, Please help me some ideas, Thanks.
Now is supported. You can use VPC network connector (Beta):
This feature is in a pre-release state and might change or have
limited support. For more information, see the product launch stages.
This page shows how to use Serverless VPC Access to connect a Cloud
Run (fully managed) service directly to your VPC network, allowing
access to Compute Engine VM instances, Memorystore instances, and any
other resources with an internal IP address.
To use Serverless VPC Access in a Cloud Run (fully managed) service,
you first need to create a Serverless VPC Access connector to handle
communication to your VPC network. After you create the connector, you
set your Cloud Run (fully managed) service configuration to use that
connector.
Here how to create: Creating a Serverless VPC Access connector and here an overview about it: Serverless VPC Access example
According to official documentation Connecting to instances using advanced methods
If you have an isolated instance that doesn't have an external IP
address (such as an instance that is intentionally isolated from
external networks), you can still connect to it by using its internal
IP address on a Google Cloud Virtual Private Cloud (VPC) network
However, if you check the services not yet supported for Cloud Run, you will find:
Virtual Private Cloud Cloud Run (fully managed) cannot connect to VPC
network.
Services not yet supported
You can now do that by running this command upon deployment:
gcloud run deploy SERVICE --image gcr.io/PROJECT_ID/IMAGE --vpc-connector CONNECTOR_NAME
If you already have a Cloud Run deployment, you can update it by running the command:
cloud run services update SERVICE --vpc-connector CONNECTOR_NAME
More information about that here
Connecting from Cloud Run Managed to VPC private addresses is not yet supported.
This feature is in development and is called Serverless VPC Access. You can read more here.
If you have a Compute Engine instance running in the same VPC with a public IP address, you can create an SSH tunnel to connect to private IP addresses through the public instance. This requires creating the tunnel in your own code, which is easy to do.
Not finding any solid answers that fit within the scope of my question.
I have a custom VPC established to allow communication between my SQL server and instance groups. My issues are limited connectivity to the SQL server from instances within the same region as the server itself.
Basically, I created a Cloud SQL instance within us-east region.
When I create a VM Instance within the same region as the SQL instance, I have no issues connecting to its private IP.
mysql -h{PRIVATE_IP} -uroot
However, running this same command from an instance in a different region results in a timeout. Both instances are configured the exact same and within the same VPC network.
I let Google allocate IP address pool for me when I created the IP. Created the private network connection within my custom VPC settings and tried tutorials provided in the Cloud Console documentation itself with no luck.
Any help getting me on the right track would be much appreciated. Thank you.
As documented, if you want to connect Cloud SQL from a Compute Engine instance using private IP, your instance must be in the same region as your Cloud SQL instance.
Keep in mind that your Cloud SQL instances are not created in your VPC network, those are created in a Google internal VPC network that then is peered to your VPC network.
Hope this helps!
I created an instance on GCP, but I am not able to access it.
This is similar to this one, but the proposed solution isn't working for me:
Unable to telnet to GCP MemoryStore
I have tried to telnet to it, I am in the same project and region, but apparently I need to be in the same network as it's a private ip, but what if you want to connect using the cloud shell? Also, how would an application running on my local machine access it?
I also included a firewall rule to make sure incoming connections are allowed.
To connect a client to a Cloud Memorystore for Redis instance, the client and the instance must be located in the same region, in same project and in the same VPC network. Please check the “Networking” document where you’ll have information on Basic network settings, limited and unsupported networks, network peering, IP address range.
You can connect to Redis from different GCP products like Compute Engine VM, Google Kubernetes Engine Cluster or Google Kubernetes Engine pod, but you can’t connect directly from the Cloud shell or from your local machine since they are not in your VPC network.
It may also have to do with a missing peering connection to your network. Check in your console at https://console.cloud.google.com/networking/peering/ to see if the peering is set up properly.
Using terraform you can use the following docs: https://www.terraform.io/docs/providers/google/r/redis_instance.html
I have created an instance of the Memory store in my project but I am unable to telnet / connect to it, either from my local or the Google Cloud Shell. Searching online, I see that other people have been granted the same host IP as mine so I am a little confused (10.0.0.3). Some assistance on how to proceed here would be great. Do I have to expose something here?
I have completed the following:
Recreated my VM on the same region as the memory store
Created a new instance of the memory store (gave me a new IP) but I am still unable to telnet
You can connect to Cloud MemoryStore provided that you are in the same project, region and network. If any of these are different you will not be able to connect.
The IP address 10.0.0.3 is an RFC 1918 private address. This is why you must be in the same network to be able to connect. Also you need to enable firewall rules to allow traffic between your instance and Cloud Memorystore.
This link shows you how to connect to Cloud Memorystore from a GCE instance.
