simple-web-healthcheck

The healthcheck will report as healthy if the HTTP request is successful and the status of the HTTP requests is not in the range of 400-599. This can be used to add healthchecks to containers that don't have access to the usual methods of health checking.

Take the following as a simple example of using the healthcheck in a distroless image:

# Build healthcheck
FROM rust:latest-bookworm AS healthcheck-builder

RUN cargo install simple-web-healthcheck

# Rest of your build...

FROM gcr.io/distroless/cc-debian12

COPY --from=healthcheck-builder /usr/local/cargo/bin/simple-web-healthcheck /healthcheck

# Copy your app here

HEALTHCHECK --interval=10s --timeout=1s CMD ["/healthcheck", "http://127.0.0.1:8080"]
