Managing Application Configuration with .env-app Files and Real Environment Variables in Oro
The following guide provides instructions on how to migrate from using a
config/parameters.yml file to using environment variables or a
.env-app file in an Oro application.
You can find more examples of DSNs in the .env-app file at the
application root folder or the corresponding documentation sections.
Managing Application Configuration with .env-app Files
In an Oro application, the configuration of the environment variables
can be managed through the use of .env-app files. These files are
used to define default values for the environment variables that are
needed by the application.
There are four types of .env-app files that can be used:
.env-app: This file contains the default values for the environment
variables needed by the app. .env-app.local: This file is an
uncommitted file with local overrides. It is intended for local
development and should not be committed to version control.
.env-app.$ORO_ENV: This file contains committed environment-specific
defaults. For example, .env-app.prod would contain the default
values for the environment variables needed by the app in a production
environment. .env-app.$ORO_ENV.local: This file is an uncommitted
environment-specific overrides. It is intended for local development and
should not be committed to version control. It’s important to note that
real environment variables take precedence over the .env-app files.
It’s also important to note that you should not define production
secrets any committed files. Instead, it’s recommended to use
environment variables for infrastructure configuration. To compile
.env-app files for production use, you can run the command
composer dump-env prod.
It’s important to note that the file name used in this guide is
.env-app, as opposed to the commonly used .env file. This is
because the .env file is commonly used by dev ops teams and other
services for managing environment variables, and it’s important to not
confuse the two files or accidentally add the wrong file to version
control. By using the .env-app file specifically for the Oro
application, it clearly differentiates the configuration for the
application and avoids any potential conflicts with other services using
a .env file. It also helps to keep the application’s configuration
separate and easily manageable.
In summary, the .env-app files provide a way to manage the
configuration of environment variables in an Oro application. They allow
for default values to be set and for local and environment-specific
overrides to be made. It’s important to use real environment variables
instead of committing sensitive information to these files and it’s
recommended to use the composer dump-env command to compile the
files for production use. Using these files allows for a more organized
and flexible way to manage the configuration of an Oro application.
Migration from config/parameters.yml to Environment Variables or .env-app
Database Connection
Instead of using the following configuration in
config/parameters.yml:
parameters:
database_driver: pdo_pgsql
database_host: '%env(ORO_DB_HOST)%'
database_port: '%env(ORO_DB_PORT)%'
database_name: '%env(ORO_DB_NAME)%'
database_user: '%env(ORO_DB_USER)%'
database_password: '%env(ORO_DB_PASSWORD)%'
database_server_version: '%env(ORO_DB_VERSION)%'
database_driver_options: []
You can now use a single environment variable with the DSN:
ORO_DB_DSN=postgres://oro_db_user:oro_db_pass@127.0.0.1:5432/oro_db?sslmode=disable&charset=utf8&serverVersion=13.7
Web Socket Connections
Instead of using the following configuration in
config/parameters.yml:
parameters:
websocket_bind_address: "0.0.0.0" # The host IP the socket server will bind to
websocket_bind_port: 8080 # The port the socket server will listen on
websocket_frontend_host: "*" # Websocket host the browser will connect to
websocket_frontend_port: 8080 # Websocket port the browser will connect to
websocket_frontend_path: "" # Websocket url path the browser will connect to (for example "/websocket" or "/ws")
websocket_backend_host: "*" # Websocket host the application server will connect to
websocket_backend_port: 8080 # Websocket port the application server will connect to
websocket_backend_path: "" # Websocket url path the application server will connect to (for example "/websocket" or "/ws")
websocket_backend_transport: tcp # Socket transport (for example "tcp", "ssl" or "tls")
websocket_backend_ssl_context_options: {} # Socket context options, usually needed when using secure transport
You can now use three environment variables with DSNs:
ORO_WEBSOCKET_SERVER_DSN=//0.0.0.0:8080
ORO_WEBSOCKET_FRONTEND_DSN=//*:8080/ws
ORO_WEBSOCKET_BACKEND_DSN=tcp://127.0.0.1:8080
Note that * means to listen to all hosts.
Search Engine Connections
Instead of using the following configuration in
config/parameters.yml:
parameters:
# search engine configuration
search_engine_name: orm
search_engine_host: '%env(ORO_SEARCH_HOST)%'
search_engine_port: '%env(ORO_SEARCH_PORT)%'
search_engine_index_prefix: '%env(ORO_SEARCH_INDEX_PREFIX)%'
search_engine_username: '%env(ORO_SEARCH_USER)%'
search_engine_password: '%env(ORO_SEARCH_PASSWORD)%'
search_engine_ssl_verification: '%env(ORO_SEARCH_ENGINE_SSL_VERIFICATION)%'
search_engine_ssl_cert: '%env(ORO_SEARCH_ENGINE_SSL_CERT)%'
search_engine_ssl_cert_password: '%env(ORO_SEARCH_ENGINE_SSL_CERT_PASSWORD)%'
search_engine_ssl_key: '%env(ORO_SEARCH_ENGINE_SSL_KEY)%'
search_engine_ssl_key_password: '%env(ORO_SEARCH_ENGINE_SSL_KEY_PASSWORD)%'
# website search engine configuration
website_search_engine_index_prefix: '%env(ORO_SEARCH_WEBSITE_INDEX_PREFIX)%'
You can now use two environment variables with DSNs:
ORO_SEARCH_ENGINE_DSN=orm:?prefix=oro_search
ORO_WEBSITE_SEARCH_ENGINE_DSN=orm:?prefix=oro_website_search
For elasticsearch search engine, use the following format:
ORO_SEARCH_ENGINE_DSN=elastic-search://valid_user:valid_password@127.0.0.1:9200?prefix=oro_search
Note that in the above examples, valid_user:valid_password@ - DSNs part can be skipped if authentication is not enabled.
Sessions Storage Configuration
Instead of using the session_handler parameter, you can now use the
ORO_SESSION_DSN environment variable. The default value is native:,
but you can provide a redis DSN to use redis as the session handler.
Redis Connections
To configure Redis connections, including types, instead of:
parameters:
session_handler: 'snc_redis.session.handler'
redis_dsn_session: 'redis://127.0.0.1:6379/0'
redis_dsn_cache: 'redis://127.0.0.1:6380/0'
redis_dsn_doctrine: 'redis://127.0.0.1:6380/1'
redis_dsn_session_type: 'standalone' #optional, current configuration is applied if it's not set
redis_dsn_cache_type: 'standalone' #optional, current configuration is applied if it's not set
redis_dsn_doctrine_type: 'standalone' #optional, current configuration is applied if it's not set
Use:
ORO_SESSION_DSN=redis://127.0.0.1:6379/0
ORO_REDIS_CACHE_DSN=redis://127.0.0.1:6379/1
ORO_REDIS_DOCTRINE_DSN=redis://127.0.0.1:6379/2
ORO_REDIS_LAYOUT_DSN=redis://127.0.0.1:6379/3
When configuring a Redis Sentinel or Cluster connection, it’s important to use the correct DSN format.
For Sentinel connections, use the following format:
redis://127.0.0.1:26379?dbindex=1&redis_sentinel=lru_cache_mon
For Cluster connections, use the following format:
redis://password@127.0.0.1:6379?host[127.0.0.1:6380]&dbindex=1&cluster=predis
Note that in the above examples, the password and dbindex values are optional and should be replaced with the appropriate values for your configuration. Additionally, in cluster example you can add multiple hosts.
And to enable the possibility of setting Redis connection configurations from environment variables, run the following command:
composer set-parameters redis
RabbitMQ Connection
Instead of using the following configuration in config/parameters.yml:
parameters:
message_queue_transport: 'amqp'
message_queue_transport_config: { host: 'localhost', port: '5672', user: 'guest', password: 'guest', vhost: '/master' }
You can now use the ORO_MQ_DSN environment variable:
ORO_MQ_DSN=amqp://guest:guest@localhost:5672/%2Fmaster
When configuring a virtual host (vhost), it’s important to note that the vhost must be URL encoded. If no vhost is provided, the default value of / will be used. As an example, if the vhost is /master, the corresponding url encoded vhost value is %2Fmaster, and if the vhost is master, the url encoded value is master.
MongoDB Connection
To configure MongoDB as a file storage, instead of:
parameters:
gaufrette_adapter.public: 'gridfs:mongodb://user:password@host1:27017,host2:27017/media'
gaufrette_adapter.private: 'gridfs:mongodb://user:password@host1:27017,host2:27017/media'
Use:
ORO_MONGODB_DSN_PUBLIC=mongodb://127.0.0.1:27017/media
ORO_MONGODB_DSN_PRIVATE=mongodb://127.0.0.1:27017/private
And to enable the possibility of setting MongoDB connection configurations from environment variables, run the following command:
composer set-parameters mongo
Enterprise License, PNGQuant and JPEGOptim Libraries Paths
These parameters:
parameters:
enterprise_licence: ~
liip_imagine.jpegoptim.binary: null
liip_imagine.pngquant.binary: null
Are now set using the corresponding environment variables:
ORO_ENTERPRISE_LICENCE=
ORO_JPEGOPTIM_BINARY=
ORO_PNGQUANT_BINARY=
Web Backend Prefix
The web_backend_prefix is now hardcoded in the config/config.yml and committed to git.
Deployment Type
The deployment_type parameter has been removed. Instead, you should use custom Symfony application environments. You can set the Symfony application environment using the ORO_ENV environment variable:
ORO_ENV=prod
Other Configuration
The following parameters are read from environment variables as before:
secretmailer_dsntracking_data_folder
These parameters should be configured in the environment variables, such
as ORO_SECRET, ORO_MAILER_DSN and ORO_TRACKING_DATA_FOLDER.
