I'm having issues when trying to connect to my Cloud SQL instance. I created a SQL Server instance, downloaded the cloud sql proxy, and everything seems to start to connect, but I keep getting the following error:
errors parsing config:
invalid "instance-connection-name": unsupported network: unix
I'm specifying the tcp port to use, but it still complains about UNIX. Here is the command I'm using when trying to connect (I replaced the actual instance connection name for privacy/security):
./cloud_sql_proxy.exe -instances=[instance-connection-name]=tcp:3306
Any help would be appreciated.
Thanks!
I tried this and it works
Rename cloud_sql_proxy_xxx to cloud_sql_proxy
Open cmd in your cloud_sql_proxy's location
Run the following command: cloud_sql_proxy -instances=[project:region:instance-name]=tcp:1433 without [ ]
From Connecting to a Cloud SQL for SQL Server using a Cloud SQL Proxy:
Depending on your language and environment, you can start the proxy using either TCP sockets or Unix sockets.
TCP sockets:
Copy your instance connection name from the Instance details page
For example: myproject:us-central1:myinstance.
If you are using a service account to authenticate the proxy, note the location on your client machine of the private key file that was created when you created the service account.
Start the proxy.
Some possible proxy invocation strings:
a) Using Cloud SDK authentication:
./cloud_sql_proxy -instances=<INSTANCE_CONNECTION_NAME>=tcp:1433
The specified port must not already be in use, for example, by a local database server.
b) Using a service account and explicit instance specification (recommended for production environments):
./cloud_sql_proxy -instances=<INSTANCE_CONNECTION_NAME>=tcp:1433 \
-credential_file=<PATH_TO_KEY_FILE> &

Connecting to database with SQL user [myuser].Password:
psql: error: connection to server at "127.0.0.1", port 9470 failed: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
I had the same error message when connecting to Postgres(Cloud Sql) using a service account.
In my setup I did run cloud_sql_proxy inside docker container.
In order to make it work I had to add extra configuration defined in step #9 https://cloud.google.com/sql/docs/sqlserver/connect-docker#connect-client
docker run -d \
-v <PATH_TO_KEY_FILE>:/config \
-p 127.0.0.1:5432:5432\
gcr.io/cloudsql-docker/gce-proxy:1.33.1 /cloud_sql_proxy \
-instances=<INSTANCE_CONNECTION_NAME>=tcp:0.0.0.0:5432 -credential_file=/config
The missing bits were: host ip on port mapping and 0.0.0.0: in cloud_sql_proxy command
There are a few things I would like to point out. The best starting point for me would be the About connection options page; both the Overview and the Before you begin sections are very helpful to get the full idea of the process and how to properly configure the user. But the most important part is the Connection Options, for the message connection to server at "127.0.0.1" I’m guessing it is a private IP, but please make sure this section is covered before starting to debug.
In your case, the logs are saying there was an error in the connection to the server…
I used the Troubleshoot guide that includes the Diagnose issues link to get to the Debug connection issues page that has a lot of useful information on how to debug any connectivity issue.
Generally, connection issues fall into one of the following three areas:
Connecting - are you able to reach your instance over the network?
Authorizing - are you authorized to connect to the instance?
Authenticating - does the database accept your database credentials?
Each of those can be further broken down into different paths for investigation.
Once determining the connection method, there are different questions that will help to guide you through the possible troubleshooting paths.
If using these guides doesn’t get you a solution, please make sure to update your answer with the results, steps, and information followed to provide further help. This would be a good example, as it has the same log error, and this other question shows that there are a few different troubleshooting paths for this specific log message, plus they have useful information for you.
So here's my use case:
Im connecting to a remote windows server machine using the pypsrp python library.
Using the pypsrp.client Client module, I am able to easily execute powershell scripts remotely on my remote machine.
Im trying to fetch DNS server information from my remote windows server.
I am able to retrieve the DNS Server IP via ipconfig /all, however - when using the retrieved IP with any of the following commands I get an error.
For example, I tried: Show-DnsServerCache -ComputerName "10.0.0.5" but It returns the following error:
Failed to get the zone information for ..Cache on server 10.0.0.5.
Any idea if any further configuration from the DNS server side is needed?
Any help would be appreciated!
The docs describe that hasura needs the postgres connection string with the HASURA_GRAPHQL_DATABASE_URL env var.
Example:
docker run -d -p 8080:8080 \
-e HASURA_GRAPHQL_DATABASE_URL=postgres://username:password#hostname:port/dbname \
hasura/graphql-engine:latest
It looks like that my problem is that the server instance connection name for google cloud sql looks like PROJECT_ID:REGION:INSTANCE_ID is not TCP
From the cloud run docs (https://cloud.google.com/sql/docs/postgres/connect-run) I got this example:
postgres://<db_user>:<db_pass>#/<db_name>?unix_sock=/cloudsql/<cloud_sql_instance_name>/.s.PGSQL.5432 but it does not seem to work. Ideas?
I'm currently adding the cloud_sql_proxy as a workaround to the container so that I can connect to TCP 127.0.0.1:5432, but I'm looking for a direct connection to google-cloud-sql.
// EDIT Thanks for the comments, beta8 did mostly the trick, but I also missed the set-cloudsql-instances parameter: https://cloud.google.com/sdk/gcloud/reference/beta/run/deploy#--set-cloudsql-instances
My full cloud-run command:
gcloud beta run deploy \
--image gcr.io/<PROJECT_ID>/graphql-server:latest \
--region <CLOUD_RUN_REGION> \
--platform managed \
--set-env-vars HASURA_GRAPHQL_DATABASE_URL="postgres://<DB_USER>:<DB_PASS>#/<DB_NAME>?host=/cloudsql/<PROJECT_ID>:<CLOUD_SQL_REGION>:<INSTANCE_ID>" \
--timeout 900 \
--set-cloudsql-instances <PROJECT_ID>:<CLOUD_SQL_REGION>:<INSTANCE_ID>
As per v1.0.0-beta.8, which has better support for Postgres connection string parameters, I've managed to make the unix connection to work, from Cloud Run to Cloud SQL, without embedding the proxy into the container.
The connection should look something like this:
postgres://<user>:<password>#/<database>?host=/cloudsql/<instance_name>
Notice that the client will add the suffix /.s.PGSQL.5432 for you.
Make sure you added also the Cloud SQL client permission.
If the Hasura database requires that exact connection string format, you can use it. However, you cannot use Cloud Run's Cloud SQL support. You will need to whitelist the entire Internet so that your Cloud Run instance can connect. Cloud Run does not publish a CIDR block of addresses. This method is not recommended.
The Unix Socket method is for Cloud SQL Proxy that Cloud Run supports. This is the connection method used internally to your container when Cloud Run is managing the connection to Cloud SQL. Note, for this method IP based hostnames are not supported in your client to connect to Cloud Run's Cloud SQL Proxy.
You can embed the Cloud SQL Proxy directly in your container. Then you can use 127.0.0.1 as the hostname part for the connection string. This will require that you create a shell script as your Cloud Run entrypoint to launch both the proxy and your application. Based on your scenario, I recommend this method.
The Cloud SQL Proxy is written in Go and the source code is published.
If you choose to embed the proxy, don't forget to add the Cloud SQL Client role to the Cloud Run service account.
I have created a Mongo container using only the base mongo:3.6.4 official docker image and deployed it to my OpenShift OKD cluster, but cannot connect to this MongoDB instance using a Mongo client from outside the cluster.
I can access the pod at http://mongodb.my.domain and successfully get the "It looks like you are trying to access MongoDB over HTTP on the native driver port." message.
When using the terminal on the pod I can successfully log-in using:
mongo "mongodb://mongoadmin:pass#localhost" --authenticationDatabase admin
But when trying to connect from outside OKD the connection fails.
My client needs to pass through a proxy before it can access the OKD pods and I do have a .der certificate file but am unsure if this is related to the issue.
Some commands I have tried:
mongo "mongodb://mongoadmin:pass#mongodb.my.domain:80" --authenticationDatabase admin
mongo --ssl "mongodb://mongoadmin:pass#mongodb.my.domain:80" --authenticationDatabase admin
I expected to be able to connect successfully but instead get this error message:
MongoDB shell version v3.4.20

I am unsure if it an issue with how I am using my MongoDB client or potentially some proxy settings on my OKD cluster. Any help would be appreciated.
The problem here is that external OpenShift routes aren't great at handling database connections. When you attempt to connect to the Mongo pod via the route, the route will accept the connection and transmit your connection to the Mongo service. I believe this transmission wraps the connection in in a HTTP wrapper, which Mongo doesn't like to handle. The OKD documentation highlights that path based route traffic should be HTTP based, which will cause the connection to fail.
You can see evidence of this when trying to connect to a MongoDB database and it returns "It looks like you are trying to access MongoDB over HTTP on the native driver port." to the browser. The user relief.malone explains this and has proposed a couple of solutions / workarounds in their answer to this question.
To add to relief.malone's answer, I would suggest that you port forward from the MongoDB pod to your local machine for development/debugging. In production, you could deploy an application to OKD that references the MongoDB service via it's internal DNS name, which will look something like this: mongodb.project_namespace.svc:27017. This way you will avoid the route interfering with the connection.
The Openshift OKD documentation on port-forwarding isn't that informative, but, since oc runs the kubectl command under the hood, you can read this Kubernetes guide to get some more information
I'm making a connection between a Google Compute Engine instance and a Google Cloud SQL instance, using the Cloud SQL Proxy.
Using this tutorial, I have managed to establish a connection by running this command:
./cloud_sql_proxy -instances=<INSTANCE_CONNECTION_NAME>=tcp:3306
However, when I quit the terminal instance I used to enter the above command the connection is lost.
How can i keep the connection alive throughout?
If you want the process of cloud_sql_proxy to run as long as the Google Compute Engine (GCE) instance is running, just make the process run in the background.
For that you just add the '&' character in the end of your command, so i would go like this:
./cloud_sql_proxy -instances=<INSTANCE_CONNECTION_NAME>=tcp:3306&
This way, as along as you don't stop the GCE instance, you can ssh to it and connect to your Cloud SQL instance (with INSTANCE_CONNECTION_NAME) with the Cloud SQL Proxy being used.
