imgproxy comes with a built-in health check HTTP endpoint at /health.
GET /health returns HTTP Status 200 OK if the server is started successfully.
You can use this for readiness/liveness probe when deploying with a container orchestration system such as Kubernetes.
imgproxy provides imgproxy health command that makes an HTTP request to the health endpoint based on IMGPROXY_BIND and IMGPROXY_NETWORK configs. It exits with 0 when the request is successful and with 1 otherwise. The command is handy to use with Docker Compose:
healthcheck:
test: [ "CMD", "imgproxy", "health" ]
timeout: 10s
interval: 10s
retries: 3
