Healthchecker
I made a simplistic Go utility that does a HTTP HEAD check to see if a server app is alive. Ideal for in distroless containers in my opinion.
All it does (and likely will ever do) is:
- Send HTTP HEAD request to a specified URL;
- On return of HTTP status code 200, exit with value 0;
- Else exit with value 1;
Usage
- Build it yourself or download a pre-built release.
- Point it to your server’s URL.
Examples
On the commandline:
./healthchecker http://127.0.0.1:8080/api/v1/status
or in a Dockerfile:
1HEALTHCHECK --interval=5s --timeout=5s --retries=3 \
2 CMD ["/healthchecker", "http://127.0.0.1:8080/api/v1/status"]
Support
