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.

I have 2 google cloud services:
Google Cloud Run Service (Node Js / Strapi)
Google Cloud SQL Service (Mysql)
I have added the Cloud SQL connection to the Google Cloud Run Service from the UI, and have a public IP for the Google Cloud SQL Service. On top of that I have added the Run Service IP to the Authorised networks of SQL Service.
If I try and connect from another server (external from Google cloud) I can easily connect to the Google Cloud SQL Service and execute queries.
But if I try and connect from inside the GCloud Run Service with exactly the same settings (Ip, database_name, etc) my connection hangs and I get a timeout error in the logs...
How to properly allow Gcloud SQL to accept connections from GCloud RUN?
I looked for other answers in here, but they all look very old (around 2015 )
You can use 3 modes to access to your database
Use the built-in feature. In this case, you don't need to specify the IP address, it's a linux socket that is open to communicate with the database as described in the documentation
Use Cloud SQL private IP. This time, no need to configure a connection in the Cloud Run service, you won't use it because you will use the IP, not the linux socket. This solution required 2 things
Firstly attach your database to your VPC and give it a private IP
Then, you need to route the private IP traffic of Cloud Run through your VPC. For this you have to create, and then to attach to the Cloud RUn service, a serverless VPC Connector
Use CLoud SQL public IP. This time again, no need to configure a connection in the Cloud Run service, you won't use it because you will use the IP, not the linux socket. To achieve this, you need more steps (and it's less secure)
You need to route all the egress traffic of Cloud Run through your VPC. For this you have to create, and then to attach to the Cloud RUn service, a serverless VPC Connector
Deploy your Cloud Run service with the Serverless VPC Connector and the egress connectivity param to "all"
Then create a Cloud NAT to route all the VPC Connector ip range traffic to a single IP (or set of IPs) (The link is the Cloud Functions documentation, but it works exactly in the same way)
Finally authorize the Cloud NAT IP(s) on Cloud SQL authorized networks.
In your case, you have whitelisted the Cloud Run IP, but it's a shared IP (other service can use the same!! Be careful) and it's not always the same, there is a pool of IP addresses used by Google cloud.
I have an AWS account with an EC2 in it that I am trying to connect to a Cloud SQL Server (MySQL 5.6) inside of Google Cloud Platform.
I have successfully set up a VPN between AWS and GCP and can echo a message over nc between an ec2 on AWS and a vm on GCP.
As GCP managed DB's are not placed inside of a VPC of my choosing I followed this guide to give the DB a private IP and to then peer that with my google VPC. I tested this works by accessing the DB via pymsql from an VM in GCP using the private IP of the DB.
However my issues come from connecting the EC2 inside of AWS to the Cloud SQL DB in the same way, I have followed this guide to allow the use of the DB's private IP from an external source but I seem to be getting stuck with how to set the routing up to the peered network the DB is sitting in using AWS Routing.
The problem has been sorted!
In the Advertised routes Settings of my Cloud Router, I had misunderstood the function of Advertise all subnets visible to the Cloud Router (Default)
I needed to instead choose Create custom routes" And then the sub-option Advertise all subnets visible to the Cloud Router.
This then allowed me to add the Cloud SQL subnet to my router to that IP block propagate over to AWS.
I have a postgreSQL CLoud SQL instance which I am connecting to via UNIX socket and the instance name from a Cloud Run container as per the documentation. With a public IP, this connection works fine. I was looking to turn off the public IP and only have a private IP, so I would not be charged for the public IP going forward.
When I first created the Cloud SQL instance, I only enabled the public IP. A couple of days later I enabled the private IP. For the assocaited network for the private IP, I accepted the default as the Cloud Run instance is in the same project.
When I turn off the public IP, my application can no longer connect to the Cloud SQL instance. I get a connection refused error:
sqlalchemy.exc.InterfaceError: (pg8000.core.InterfaceError) ('communication error', ConnectionRefusedError(111, 'Connection refused'))
As stated above, I did follow the instruaction on the Connecting to Cloud SQL from Cloud Run page:
https://cloud.google.com/sql/docs/postgres/connect-run
I even ran the gcloud command to update an the exsiting deployed revision after turning off the public IP and only having the private IP available but it made no difference.
Is a public IP required for a connection from Cloud Run to Cloud SQL? I do not see that in the connection documentation page. Or is there something else I missed when trying to switch over to only having a private IP? Or do I need to create a new Cloud Instance without a public IP and go through the instructions for connecting Cloud Run via an instance anme again?
Is a public IP required for a connection from Cloud Run to Cloud SQL? I do not see that in the connection documentation page.
On the Connecting to Cloud SQL from Cloud Run page, it says "Note: These instructions require your Cloud SQL instance to have a public IP address configured."
Private IP access is access from a Virtual Private Cloud (VPC). In order to access your instance through a VPC, the resource you are connecting to needs to be a part of the VPC. Cloud Run doesn't currently support VPC access, so you'll need to use have a public IP for now.
TL;DR: Open a case to the Google support
Your case is interesting because, by design, I think it's not yet supported.
In fact, when you create a Cloud SQL database with a private IP, a network peering is done between your VPC and the Cloud SQL VPC (or something equivalent).
In addition, today, it's not possible to plug your Cloud Run instance to your VPC. With function and App Engine, you have a serverless VPC connector, and not yet with Cloud Run (it's coming!).
The serverless VPC connector perform the same things as the Cloud SQL private IP, I mean a peering between your VPC and the Cloud Functions (or App Engine) VPC (or something equivalent).
And even if the serverless VPC connector is available on Cloud Run, it's not sure that it work because of network peering transitivity. In short, If you have a peering between VPC A -> VPC B and between VPC B -> VPC C, you can't reach VPC C from VPC A by performing an hop in VPC B. Replace A by VPC Cloud Run, B by VPC of your project, and C by VPC Cloud SQL.
Only directly peered networks can communicate. Transitive peering is not supported. In other words, if VPC network N1 is peered with N2 and N3, but N2 and N3 are not directly connected, VPC network N2 cannot communicate with VPC network N3 over VPC Network Peering.
I didn't check with AppEngine or Cloud Function, but this design shouldn't work.
But I'm not sure, that's why a case to the Google support will allow you to have a clear answer and maybe inputs on the roadmap. Any valuable information from Google Support are welcomed here!
I was also getting the following error when I was trying to connect to postgres using the following command from cloud shell:
gcloud sql connect
it seems your client does not have ipv6 connectivity...
What I do is that I login to one of the pods deployed using Google cloud Kubernetes using the following command:
kubectl exec --stdin --tty java-hello-world-7fdecb9894-smql4 -- /bin/bash
Then for 1st time I ran:
apt-get update
apt install postgresql-client
And now I can connect using:
psql -h postgres-private-ip -U username
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 want to connect to Cloud SQL from a different GCP project.
Cloud SQL is location in ProjectSQL and a VPC network is there in ProjectSQL project with name sql_vpc
There is another project ProjectDataflow and this has a vpc dataflow_vpc. I want to connect to cloudSQL from ProjectSQL with the VM launched in ProjectDataflow project
Things I have tried with success and failure.
Private ACCESS:
VPC Peering:
Enable Private IP access in Cloud with the vpc sql_vpc
Creating VPC peering between dataflow_vpc and sql_vpc
This solution does not work because you can not access the Peered Network.
https://cloud.google.com/sql/docs/mysql/private-ip
Status: FAILED
Shared Network
As per doc I can create the CloudSQL in shared VPC network, that says I
have to create the CloudSQL in host project, and to access the Cloud
SQL from VM instance, it has be in the same network as of authorized
private ip network of Cloud SQL
Status: NOT TRIED but looks to be Negative
Public Access:
Create a Cloud NAT in ProjectDataflow with dataflow_vpc with manual IP
Use the Cloud NAT public ip to whitelist in CloudSQL instance
Now I can access the CloudSQL from project ProjectDataflow using CloudSQL Public IP
STATUS: Success
Please share your experience accessing Cloud SQL from another project.
Is there any best practice to connect cloud SQL from another gcp project?
EDIT:
Newer instances seem to be having this option enabled by default and there's no need to contact support anymore. However, if after all the process, the setup is still not working, it may be needed to contact support.
IMPORTANT: The VPC peering option will not work anymore, as stated in the documentation, more precisely in the Considerations topic. Then the only available option to achieve it is using Shared VPCs
The process of interconnecting a Cloud SQL with another GCP project it is pretty straightforward following the documentation. The only thing you need to take into consideration in order to make it work is that you will have to request Google Cloud Support to enable custom routes for your Cloud SQL speckle umbrella instance in which your Cloud SQL is running under otherwise you won’t be able to access your Cloud SQL within your GCP project.
The following steps will work for you:
-Configuring VPC for Cloud SQL instance
Inside the project where you have your Cloud SQL instance, create a
VPC network with the ip address range of your desire. Choose the same
zone for the VPC in which your instance is located.
-Configuring VPC for GCP project
Now switch to the project where your CloudDataflow instance is located
and follow the same process. Create the VPC network being careful that
the IP ranges do not collide between each other. You can use the following tool to
check if the IP addresses range collide. Also take into consideration
that both VPC networks must be in the same zone.
-Connecting VPC of both projects with peering
Once both VPC networks are created it is needed to configure the VPC
network peering from both projects. From the Cloud SQL instance side,
configure the peering specifying the project and VPC network name to
connect with and also select the option to export custom routes. This
way the other part of the peering, in this case your GCP project, will
have visibility of your Cloud SQL instance. Now, from the GCP project
side, configure the peering specifying the Cloud SQL project name and
the VPC network name to connect with. The same way we did with the
Cloud SQL peering, we have to set up the peering to import custom
routes as it will receive exported routes coming from the other side
of the connection, which in our case is your Cloud SQL instance.
Here you can check more information about importing and exporting routes between any VPC network peerings.
-Request Google Cloud Support to enable for you the exchange custom routes for your Cloud SQL
Reach Google Cloud Support and ask them to enable the exchange of
custom routes for your speckle-umbrella VPC network associated with
your instance that is automatically created upon the Cloud SQL
instance is created.
Take into consideration that this last step is very important, all SQL projects run under the umbrella project, hence without requesting Google Cloud Support to enable the exchange custom routes for your instance this will never work.
Shared VPC
As for Shared VPC, the only thing you need to take into consideration is that you need to enable the option once creating your Cloud SQL instance as you can’t add it afterwards.
You will find a configuration guide for Shared VPC in the following link.
