My Laravel app can't connect to Google Cloud redis server

  • 772

cachéI have a Laravel application already mounted on Google Cloud, the needs of the project forced me to use redis. Everything works fine on my local machine but when I push changes to make it work in production but I get the errorConnection timed out [tcp://ip_redis:6379]

My settings in yamlwhich is like envbut for Google Cloud:

 REDIS_CLIENT: predis
 REDIS_HOST: ip_redis
 REDIS_PASSWORD: null
 REDIS_PORT: 6379

I have created the server redisin Google Cloud too, with the following characteristics:

Nivel
Básico

Ubicación
us-central1-a

Red autorizada
default (my_project)

Rango de direcciones IP
rango_ip/29

And when initializing the command configuration gcloud initI made sure to configure it in the same zone as the redis server ( us-central1-a) and I deployed the application.

I kept getting the same error.

So I did some more research and went in Redes de VPC > Firewalland created two rules to see if that was what was wrong.

The configuration of the first rule was (note that I put the same range that the server gave redis): enter image description here

The second rule is identical except for traffic type, now I set it to outgoing traffic.

I even created a VM to test the connection using telnetand yes I have an answer, yes the server works correctly redis.

Also, I have implemented CloudFlarewhat made me think that I could probably be blocking it somehow, but I added an exception rule with the server IP ( ip_redis) to allow the connection, but it did not work, apparently CloudFlareit does not influence this connection.

Also, I saw this answer , about modifying the part of post-install-cmdthe file composer.json, but my file didn't have that part, I decided to add it to the scriptsanyway, it didn't work either. mark the same error

But still after all this I haven't been able to get the Laravel app to connect to the redis server.

    What was needed was a special connector, which is created in VPC Network > Serverless VPC Access.

    enter image description here

    And click on create connector:

    With special care in setting the region, to make it match the region of your application.

    On the network, default.

    In the IP range, we can put the hint below.

    enter image description here

    It is also very important to activate the option AUTHfor the server Redis, otherwise authentication errors will appear. Once the option is activated, you have to copy the String AUTHone that Google Cloud gives you when you see the details of your server Redis. We paste that string yamlinto the variable REDIS_PASSWORD.

    Now, we must color a setting the yamlto do deploy:

    vpc_access_connector:
    name: 'projects/mi-proyecto/locations/us-central1/connectors/conector'.

    Now it only remains to run the command to do deploy:

    gcloud beta app deploy -v=production-cache -q

    It must be used betasince sometimes the normal command can ignore the section of vpc_access_connector.

    And ready.
