I am new to GCP. I created a cloud-SQL instance (PostgreSQL 14) and tried to connect to it from the app engine.
I am using the following code on github.
https://github.com/GoogleCloudPlatform/python-docs-samples/tree/9d4343d0845d6e20e0b08d1242c38aaaf0d9c075/appengine/standard_python3/cloudsql
main_postgres.py-> as my main file
I updated the connection information in the app.yaml file according to the instance and database I created. I did not make any other changes to the main_postgres.py file.
I deployed app engine in the directory with main_postgres.py
After deploying when I go to the link it says :
I am not able to figure out where I am going wrong. any help is appreciated. thanks!
I managed to replicate the github link you provided. I solved it by renaming the main_postgres.py file to main.py. Here's the screenshot of the output link:
This issue dont seems related to DB but your application configuration.
check errors by running this in cloud shell when you hit appengine url.

I'm trying to change the entry web page that gets launched in my Google App Engine deployment. It's a simple J2E web project, using IntelliJ with Cloud Code plugin. The default deployment points to 'index.jsp', which gets automatically created with the project. I want to change that, to point to a custom form I have built, e.g. 'form.xhtml'.
Steps I've been through so far...
Created base Google App Engine (Standard)
Configured GAE localhost
Configured GAE deployment server
I can do this easily on the localhost server, by just changing the server URL, e.g. from http://localhost:8080/ to http://localhost:8080/Ex_1.xhtml
I can't work out how to change this on the deployment server though. There's no URL option like there is with localhost. As a result, when I deploy my code it still just launches the default index.jsp.
I've looked through the GAE deployment descriptor documentation, but it doesn't mention how to do this. I'm sure it's a very simple change, I just can't put my finger on it.
Can anyone help?
I've resolved this, in case anyone else has a similar issue. You need to add the 'entry page' into web-xml, using the 'welcome-file-lists' tag. For some reason Eclipse adds this automatically but IntelliJ doesn't. If this isn't added, the App Engine deployment server points to the default index.jsp
<welcome-file-list>
<welcome-file>my-entry-page.xhtml</welcome-file>
</welcome-file-list>
I am new to React and created a simple react app using create-react-app , it builds and runs fine on local. I created a Azure Build and release pipelines and tried deploying using App Services , refereed below Microsoft link to implement the same.
https://devblogs.microsoft.com/premier-developer/deploying-react-apps-to-azure-with-azure-devops/
Build and release pipeline runs successfully however when I click the Azure app services link to access the react app, I receive below message :-(
"This react-naturalone.azurewebsites.net page can’t be found
No web page was found for the web address: https://react-naturalone.azurewebsites.net/
HTTP ERROR 404"
Can someone please suggest what I am missing.
fyi, I am using react-router, hence added the web.config as mentioned in the link above.
Thanks

I'm thinking that there is a problem with your deployment pipeline. The first step for your here is to go to your Azure portal and open up your app service. From your app service, go to -->Development tools --> App service editor.
Do you see your code inside it? If you don't, you can confirm that the code didn't deploy correctly. If you do, then you have a misconfiguration somewhere in your app that is preventing anybody from seeing it.
I am new at Google Cloud and I would like to know if there is a way to edit only one file inside of an App Engine application.
This is my problem:
I am migrating from a normal hosting to google cloud and I am having some problems with my PHP code, I am using the same version like locally but I am getting some error in the cloud, so I need to change 1 or 2 files, update them and test the app, so is there any way to change that file directly on the server? To deploy i am using this command:
gcloud app deploy
But it takes about 10 minutes to deploy so is too slow my testing. Any suggestions?
Thanks.

For the standard environment the answer is no, you need to deploy a new version of the app to modify a file. So the advice would be - make the most of testing your app locally. See somehow related Google AppEngine - updating my webapp after deploy
For the flexible environment (possibly your case as you mentioned 10 min deployment time, typical for the flexible env) there might be stuff to try, but tedious, see Google AppEngine - updating my webapp after deploy
There is a way to edit directly into the instance.
ssh into your instance and then start shell on your running docker as guided in this url. https://cloud.google.com/appengine/docs/flexible/python/debugging-an-instance
After login you can see your php source files.
Basically you will not have any editor. So do
$> apt update
$> apt install nano
$> nano index.php // edit your files
you can see something like
There is no way to change 1-2 files on the server so that it would update the app. Deployment is the process of updating the live app. If you want some changes to be made to the app that is already deployed, you will have to redeploy - there is no way around it. This is why it is recommended to test the app locally before (re)deploying so that you are sure everything is working fine.
If locally everything works fine and issues start happening only when the app is deployed, this should be investigated further and I would advise you to open a new question and provide as much details as possible regarding the problems, including full stack trace of the error, related code parts, your app.yaml contents as well.
Using Eclipse, I am experiencing an error when trying to deploy a rather basic web app with JAX-RS and JAXB. It runs okay locally, but when trying it on the remote servers I get the message shown below...
'Deploying to Google' has encountered a problem / This application does not exist
Below shows my appengine-web.xml
The XML file illustrates that I am using the same name in the xml as what's specified in the project properties...

Any answers will be appreciated. At one point my browser was not logged in to the target google account, so I swapped to the correct one a little later, Google does render the application name as expected.
Okay, this was simple in the end! Eclipse performs an auto-login to the Google account, unfortunately I created the Eclipse project whilst being logged in to one Google account and then tried to specify the application name afterwards.
You'll see in the bottom-right (or bottom-left in some versions) a Google icon with the name of the user that you are logged in as. If that's not the account where your application is defined, then simply logout of that account, then login as the correct Google account.
Now there's no error :-)
I know this question is super old but I had this issue all day and finally I found a solution. Maybe it will help someone out in the future.
After you create a project in Google Cloud Platform, you must go to google cloud shell in your project and run the command
gcloud beta app create
After you run this command, you will get prompted to choose a region. Then go back to eclipse and try deploying it. It worked for me.
There are not just 1 way can cause this problem. For me, I have this problem when I create the project using Maven. But I don't have the same issue if I directly create the project from the Google plugin.
There might be another issue, when you register with Google App Engine, you receive email indicating your activation. If you have not received the email yet, this problem could occur too.
Another issue could be to use the gmail account for the Google App Engine to avoid any such errors.
I am new to Google App engine and I have tried to run an demo application called guestbook to connect to Google cloud sql from the Google app engine with app-engine-sdk version 1-7.0. But each time I am getting an error saying "java.lang.IllegalStateException: System property rdbms.driver must be set at com.google.appengine.api.rdbms.dev.LocalRdbmsServiceLocalDriver.registerDriver(LocalRdbmsServiceLocalDriver.java:80)". I double check my code and every thing looks ok, and I still have no glue where the error coming from.
Below is a snippet of my connection code :
c = DriverManager.getConnection("jdbc:google:rdbms://my_instance/my_database");
and mysql-connector-java-5.1.21-bin is in the class path,
and I have enable Google cloud sql in the Google app engine,
and I have checked the use of Google Cloud instance in the app engine as well with the my instance of the database, database name, login , and password,
and I am using Eclipse Juno.
I think I have missed something important; so would you please help me if you know what I have missed.
Thank you very much in advance,
Minh
Once you are new to GAE I recommend to give a try on the Big Table database. Using it you will not have to setup any database localy. So just the eclipse plugin will be enough for your first test. The Guestbook uses this database so it will be easier to follow the tutorial.
