A very simple ReactPHP app for K3S Example Project
The logic is exactly the same as here. So, it just providing the /metrics
endpoint with Prometheus metrics and sending "I'm alive" log.
You can configure it via the following environment variables:
- name: PROJECT_NAME
value: "react-php-test-app"
- name: CONSOLE_LOG_TIMEOUT
value: "5000"
- name: METRICS_ROUTE
value: "/metrics"
- name: METRICS_PORT
value: "8000"
- name: METRICS_COMPONENT
value: "applications"
- name: METRICS_SOURCE
value: "react-php-test-app"
- name: METRICS_NAMESPACE
value: "default"
The app is just sending PROJECT_NAME is alive
message to the console every CONSOLE_LOG_TIMEOUT
milliseconds and exposing the metrics endpoint on the METRICS_ROUTE
route and METRICS_PORT
port.
There are only few metrics: memory_peak_usage
, memory_usage
, php_info
. And the one is custom one http_requests_counter
which is a counter of all the requests to the application just as an example of custom metric you can add.
The image I'm using for K3S Example Project is there you can pull it by running docker pull madloptus/reactphpapp
Not sure even if someone will need it, but if you want to run the app locally, there is the docket-compose file for that. Just run docker-compose up
and the app will be available on the http://localhost:8000
.
