Hi,

I'm triing to deploy a Laravel app on google app engine! 
When I run gloud app deploy in the google sdk command line, I'm getting this error : 
(gcloud.app.deploy) INVALID_ARGUMENT: Network 'default' does not exist

This is my app.yaml file :

runtime: php  
env: flex  

runtime_config:
 document_root: public 

skip_files:
 - .env 

env_variables:
 APP_ENV: local

Hello Ben, 

This is usually indicative of a situation characterized by a missing default network. Your default network could have been deleted at a certain moment in time. Recreating the default network should address the issue, or specifying your actual network in app.yaml:

network:
  instance_tag: TAG_NAME
  name: NETWORK_NAME
  subnetwork_name: SUBNETWORK_NAME

You may refer to the "app.yaml Configuration File" documentation page for related detail.

I already tried with adding this to my app.yaml file but it's not working.
I thing I don't have the right values for the TAG_NAME and the NETWORK_NAME.
Do you know what value should I put there ?
Thanks in advance


network:
  instance_tag: TAG_NAME
  name: NETWORK_NAME
  subnetwork_name: SUBNETWORK_NAME

instane_tag can be anything of your choice. you can use for example "aef-instance". this tag is assigned to each instance of the service upon its creation.
The network name has to be the short name not the resource path  (for example, mynetwork rather than https://www.googleapis.com/compute/v1/projects/my-project/global/networks/mynetwork).
For subnetwork_name use also the short name like subnetwork1 rather than https://www.googleapis.com/compute/v1/projects/my-project/global/networks/default/subnetworks/subnetwork1


if that doesn't work. can you post the error that you receive after these modifications?

Hello,

This doesn't work. I don't know what to put there on the instance_tag.
And I have read so many times the Google documentation about Network settings.

C:\Users\someproject>gcloud app deploy
ERROR: (gcloud.app.deploy) An error occurred while parsing file: [C:\Users\someproject\app.yaml]
  in "C:\Users\someproject\app.yaml", line 42, column 17

The line 42 is instance_tag: aef-instance

 network:
  instance_tag: aef-instance
  name: mynetwork
  subnetwork_name: subnetwork1

If someone could help me, it will be really nice. Thank you in advance !

The error indicates your yaml file is not properly formatted.
Try checking your indentation somewhere. Maybe something is not well aligned or given more spacing somewhere.
Generally it is two(2) spacing something of the sort. Let me know if the error still persists. For instance take a look at your

beta_settings:
   cloud_sql_instances: ****************************

It is way much indented than the others

Best,
Mua

Hello,

Thank you, you're right for the identation.
But now I'm getting another error about the network. 
At this line in app.yaml : "name: mynetwork "

Here is the error message:
Finished Step #1
PUSH
DONE
------------------------------------------------------------------------------------------------------------------------

ERROR: (gcloud.app.deploy) INVALID_ARGUMENT: Network 'mynetwork' does not exist

And that's my app.yaml file :

env: flex  

runtime_config:
 document_root: public   

skip_files:
 - .env 

network:
  instance_tag: aef-instance

Hi,

You need to have added the tags before you can use them in your app.yaml file. Refer to this
https://cloud.google.com/vpc/docs/add-remove-network-tags you can create the tags via the console or via
gcloud command as follows

gcloud compute instances add-tags [INSTANCE-NAME]  --zone [ZONE]  --tags [TAGS]

Only then you can use them in your app.yaml file. As of now that error is due to no network tags being
created prior to deployment. I hope this helps.

Cheers,
Mua

As previously mentioned, the "aef-instance" tag was probably not added prior to being referenced in the "app.yaml" file. Here is the documentation [1] on how to properly set the network settings in the configuration file, with an explanation on the "instance_tag" and "name" option. Here is how [2] to add the network tags that will subsequently be referenced.

Hello,

I can't create that tag and still don't know why ?

C:\someproject>gcloud compute instances add-tags aef-instance --zone europe-west1-b --tags mynetwork
ERROR: (gcloud.compute.instances.add-tags) Could not fetch resource:
 - The resource 'projects/*************/zones/europe-west1-b/instances/aef-instance' was not found

Do I need to create a VM instance first or a firewall-rules before ?
Like that : gcloud compute firewall-rules create

 Thank you so much for your help !!

Hi Sarah,

Under the App Engine flex environment, the app is served by underlying Compute Engine (GCE) instances already by default. You can read more about this here [1]. There is no need to create new ones. When using the “gcloud compute instances add-tags” command, the ‘instance-name’ should be the actual name of the existing GCE instance, instead of the tag you are assigning it. If you want the “instance_tag” to be set as ‘aef-instance’, the complete command should look like:

gcloud compute instances add-tags EXISTING_GCE_INSTANCE_NAME --zone europe-west1-b --tags aef-instance

You can read more about this command here [2]. Once that instance has been tagged properly, you can associate this newly tagged instance with the network name in the “network” section of the ‘app.yaml’ file. In order to get the existing GCE instance name, you may look at the bottom of the page from the Instances page [3] of your project in the Console. Make sure the correct service is selected in the dropdown menu at the top.

Thank you so much for your help!
But I still don't know how to find the  EXISTING_GCE_INSTANCE_NAME ?
Where can I find this information?
I tried the project name and the sql instance name ! 
And of course, it's not working

The Network part of the yaml is optional and should be use only if you have one setup, other than that it is not needed.
Could you try remove it, and deploy to see if it'll work, make sure the yaml formatting is correct, as this might have been the original
issue here.
