Hey Hanene,

Hm, try to do simpler:



$ git add .
$ git commit -m"Add SymfonyCloud configuration"

If still not work, please, make sure your have a Git repository initialiazed in the project root dir and those files are inside of your project root dir.

Cheers!

Ok it works .Could you give the project Id

|

Victor SFCASTS hanen 6 years ago

Hey Hanene,

Glad it works! Hm, what project ID are you talking about? :) Do you see a question about project ID in your console? After what command? Could you copy/paste it? :)

Cheers!

I run symfony.exe link [project-id] to get project IDs via symfony.exe projects... Infact I don't have a credit card :(...

Victor SFCASTS hanen 6 years ago

Hey hanene,

Ah, it won't work :) I can't give you my project ID, because even if you would have my project ID - you won't be able to use it as you just don't have access to my project. You need to create your own project in SymfonyCloud and use it for training purposes if you want. Or just skip chapters that require SymfonyCloud account if you don't want to buy it.

Cheers!

Hello.

After symfony deploy I get following error:

E: Error parsing configuration files:
      - applications./.platform.app.yaml.mounts.hooks: Expected a string, received None
      - applications./.platform.app.yaml.mounts.build: Unsupported volume URL
      - applications./.platform.app.yaml.mounts.deploy: Unsupported volume URL

.plaftorm.app.yaml contents:

name: app

type: php:8.1

runtime:
    extensions:
        - apcu
        - mbstring
        - sodium
        - iconv
        - ctype
        

#variables:
#    php:
#        # uncomment on PHP 7.4+
#        #opcache.preload: config/preload.php

build:
    flavor: none

disk: 512

web:
    locations:
        "/":
            root: "public"
            expires: 1h
            passthru: "/index.php"

    "/var": { source: local, source_path: var }
    hooks:
    build: |
        set -x -e

        curl -fs https://get.symfony.com/cloud/configurator | bash
        
        symfony-build

    deploy: |
        set -x -e

        symfony-deploy

Hey Rainer-S,

Please, double-check the indentation in your .plaftorm.app.yaml - it seems you should indent the build & deploy items with 4 spaces back to the root of the file, i.e.:

# ...

mounts:
    "/var": { source: local, source_path: var }

hooks:
    build: |
        set -x -e

        curl -fs https://get.symfony.com/cloud/configurator | bash
        
        symfony-build

    deploy: |
        set -x -e

        symfony-deploy

Right now it looks like the "hooks" is nested into "mounts" that is not correct.

Cheers!
