FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package health-check-bundle
HealthCheckBundle
A Symfony bundle providing a /health endpoint to monitor your application and its dependencies.
Installation
Register the bundle
Import routes
Allow public access
If you use the Symfony SecurityBundle, make sure the health route is publicly accessible:
Configuration
| Option | Type | Default | Description |
|---|---|---|---|
path |
string |
/health |
URL path for the health check endpoint. |
secret |
string? |
null |
Token expected in the configured header. If null, details are never exposed. |
header |
string |
Authorization |
Name of the HTTP header used to send the secret token. |
timeout |
int |
5 |
Maximum execution time in seconds for each individual check. |
cache.enabled |
bool |
true |
Enable caching of health check results. |
cache.ttl |
int |
300 |
Cache TTL in seconds (5 minutes by default). |
checks.doctrine |
bool |
true |
Auto-register Doctrine DBAL checks (one per connection) if doctrine/dbal is installed. |
checks.asset_mapper |
bool |
true |
Auto-register AssetMapper check if symfony/asset-mapper is installed. |
Usage
GET /health
Without auth header (or without a configured secret):
With a valid auth header:
Console command
Run checks from the command line:
Built-in checks
The bundle ships with built-in checks that are automatically registered when the corresponding packages are installed:
| Check | Package required | What it does |
|---|---|---|
doctrine |
doctrine/dbal |
Runs SELECT 1 on each configured DBAL connection |
asset_mapper |
symfony/asset-mapper |
Checks that manifest.json exists (assets compiled) |
Built-in checks are enabled by default and auto-detected via class_exists() and service availability. One check is registered per Doctrine connection (e.g. doctrine_default, doctrine_analytics). The asset mapper check verifies that public/assets/manifest.json exists (i.e. asset-map:compile has been run). You can disable them in your configuration:
Creating a custom check
Implement HealthCheckInterface — the service will be automatically discovered and registered:
Querying a remote health check endpoint
HealthCheckClient lets you query the /health endpoint of another Symfony application (e.g. a different site running this same bundle) and get back a typed result instead of raw JSON. It requires symfony/http-client:
HealthCheckClient::check() returns a RemoteHealthCheckResult:
| Property | Type | Description |
|---|---|---|
reachable |
bool |
false if the request failed at the network level or the response couldn't be parsed |
report |
?HealthCheckReport |
The remote health report (status + checks), present only when reachable is true |
error |
?string |
Error message, present only when reachable is false |
If no secret (or an empty string) is provided, the remote endpoint will only return its global status (no checks detail), matching the unauthenticated response documented above.
HealthCheckClient is only registered as a service when symfony/http-client is installed (auto-detected, like the built-in checks). If it isn't installed, autowiring HealthCheckClient fails with Symfony's standard "service not found" error at compile time, rather than a runtime exception.
Flex recipe
Sample configuration files are available in the recipe/ directory for use with Symfony Flex.
