I want to Running a basic Apache web server on google cloud (https://cloud.google.com/compute/docs/tutorials/basic-webserver-apache)
But I can't connect with my External IP .
Last month I succeed launching a server with the External IP, why can't this time?
I have Allow HTTP Traffic box.
How to find the bug?
Restart the VM then check out if the Firewall-rules still activated:
$ gcloud compute firewall-rules list | grep 80
if not is created the firewall-rule, set it up again:
$ gcloud compute firewall-rules create default-http --allow tcp:80
hope it can be useful to you

I was able to login via ssh normally but it just stopped working.
I tried to stop and start instance but it doesn't help. Could anybody help?
You could check your Firewall Rules in GCP console and if it is not created you can create the rule and with port number 22
$ gcloud compute firewall-rules create default-allow-ssh --allow tcp:22
After try to connect to SSH...
I am getting the following disconnection issues in the GCP Jupiter notebook.
error code: 4010
and
error code: 1006
Can you please suggest some solution?
As part of the IAP configuration steps, you should create a firewall rule that allows ingress traffic to the SSH port from the IAP address range:
GCP Console => VPC network => Firewall rules => Create Firewall Rule
Name: allow-ingress-from-iap
Direction of traffic: Ingress
Target: All instances in the network
Source filter: IP ranges
Source IP ranges: 35.235.240.0/20
Protocols and ports: select TCP and enter 22 to allow SSH
Identity-Aware Proxy > Doc > Setting up IAP for Compute Engine
The error 1006 appears in the GCP Console UI after 1 hour of inactivity of the SSH session via IAP with VMs with Internal IP only, and this is a session timeout on the Google side.
As #mebius99 has mentioned, IAP (Identity-Aware Proxy) requests come from the IP address range 35.235.240.0/20.
Your network firewall must allow these requests to be able to SSH through IAP.
One way to do that (create a firewall-rule) is to run gcloud compute firewall-rules create command.
To do that, first open the cloud shell on the Google cloud console,
Then once the cloud shell opens up, run the following:
gcloud compute firewall-rules create ssh-ingress-from-iap --allow=tcp:22 --source-ranges 35.235.240.0/20 --network [network-name]
Replace [network-name] with your network name (the default VPC network is named: default)
If the above solution doesn't work (or have a similar firewall rule in place already), consider checking the network tags (on the firewall-rules and the VM). It maybe the case that your firewall-rule is allowing the requests to only certain instances that has some tags and the instance you're trying to SSH into doesn't.
For me the error 1006 was related to system Time. I had changed the system time manually to another time zone. SSH worked when system time was sy
Create a firewall for port 22 and add this IP 35.235.240.0/20
attach it to all VM so you will able to establish connection
When trying to connect to my google cloud RDP i receive an error saying that my RDP is offline when it is not. At first I thought the error was on my side, but after trying with another RDP it worked fine, any ideas?
You should first check that port 3389 is open on the GCE firewall. If not, run a command like this to create the rule $ gcloud compute firewall-rules create rdp --allow tcp:3389 --source-ranges 0.0.0.0/0 . More info is available here.
Here is a document to troubleshoot RDP issues, you can try these steps. Also you can connect to the instance using a serial console.
I have REST API Java application and want move it to cloud.
But I don't understand which tutorial use.
I already have docker image in Container Registry made by Jib and want connect it with some cloud database (Cloud SQL/Spanner).
How change this connection props to cloud?
db.driver=com.mysql.cj.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/db
db.username=usrname
db.password=pswd
db.entity.package = com.example.model
We do this through Cloud SQL Proxy docker image: https://cloud.google.com/sql/docs/mysql/connect-docker
Enable the Cloud SQL Admin API.
Install the mysql client on the Compute Engine instance or client machine, if it is not already installed.
If needed, install the Docker client
4.Install the Proxy Docker image from the Google Container Registry.
If you are running the Proxy Docker image on a local machine (not a Compute Engine instance), or your Compute Engine instance does not have the proper scopes, create a Google Cloud Platform service account.
Go to the Cloud SQL Instances page in the Google Cloud Console.
Select the instance to open its Instance details page and copy the Instance connection name.
Start the proxy.
docker run -d \
-v <PATH_TO_KEY_FILE>:/config \
-p 127.0.0.1:3306:3306 \
gcr.io/cloudsql-docker/gce-proxy:1.16 /cloud_sql_proxy \
-instances=<INSTANCE_CONNECTION_NAME>=tcp:0.0.0.0:3306 - credential_file=/config
Start the client
mysql -u <USERNAME> -p --host 127.0.0.1
Then connect using
db.driver=com.mysql.cj.jdbc.Driver
db.url=jdbc:mysql://127.0.0.1:3306/db
db.username=usrname
db.password=pswd
db.entity.package = com.example.model
If you want to reach a CloudSQL database from a GKE cluster, you have 2 solutions:
You can use configure a private ip on CloudSQL and then reach it directly to this IP. For this, your GKE cluster must be configured as VPC native.
You can attach a sidecar to your main container which open a cloud sql proxy connection to your database. This solution is quite similar of the answer of #ParthMehta. Here the description (and the github example) of this sidecar configuration
For Spanner, it's different because you can't use private IP or cloud SQL proxy binary. you have details on this page for the configuration and the dependencies
As you can see, you connect your instance directly with the ressource definition (/projects/..../instance/.......). Your config file should look like to this:
db.driver=com.google.cloud.spanner.jdbc.JdbcDriver
db.url=jdbc:cloudspanner:/projects/{YOUR_PROJECT_ID}/instances/{YOUR_INSTANCE_ID}/databases/{YOUR_DATABASE_ID}
db.dialect=com.google.cloud.spanner.hibernate.SpannerDialect
i´m using ubuntu 18.04 lts in google compute engine and glassfish server running perfectly as seen in the following image:
already configure a static ip to the gcp vm:
and i remove the S so I can access my server
and i also add port 8080 to be able to connect and nothing keeps throwing me error
already try like this :http://34.94.96.242:8080
and this: http://34.94.96.242:4848
And i still don't have access
Did you try reaching your glassfish server inside the Compute Engine?, I mean using for example:
curl localhost:[PORT]
in the terminal and see the output, if OK, your installation is OK and probably there is a firewall rule missing, so you have to create it with the specific port.
For example for enabling traffic in port 22 for using SSH, you need to execute the following command in cloud shell:
gcloud compute firewall-rules create default-allow-ssh --allow tcp:22
or for opening port 8080
gcloud compute firewall-rules create default-allow-glassfish --allow tcp:808
Take a look at this documentation about how to set up firewall rules in GCP step-by-step.
