One day you may want to replace the standard error pages of your HTTP server with something more original and pretty. That's what this repository was created for :) It contains: - Simple error pages generator, written in Go - Single-page error page templates with different designs (located in the [templates](https://github.com/tarampampam/error-pages/tree/master/templates) directory) - Fast and lightweight HTTP server - Already generated error pages (sources can be [found here][preview-sources], the **demonstration** is always accessible [here][preview-demo]) ## 🔥 Features list - HTTP server written in Go, with the extremely fast [FastHTTP][fasthttp] under the hood - Respects the `Content-Type` HTTP header (and `X-Format`) value and responds with the corresponding format (supported formats are `json` and `xml`) - Writes logs in `json` format - Contains healthcheck endpoint (`/healthz`) - Contains metrics endpoint (`/metrics`) in Prometheus format - Lightweight docker image _(~4.3Mb compressed size)_, distroless and uses the unleveled user by default - [Go-template](https://pkg.go.dev/text/template) tags are allowed in the templates - Ready for integration with [Traefik][traefik] ([error pages customization](https://doc.traefik.io/traefik/middlewares/http/errorpages/)) and [Ingress-nginx][ingress-nginx] - Error pages can be [embedded into your own `nginx`][wiki-usage-with-nginx] docker image - Fully configurable (take a look at the [configuration file](https://github.com/tarampampam/error-pages/blob/master/error-pages.yml) and [project Wiki][wiki]) - Distributed using docker image and compiled binary files ## 🧩 Install Download the latest binary file for your os/arch from the [releases page][releases] or use our docker image: [][docker-hub-tags] | Registry | Image | |-----------------------------------|-----------------------------------| | [Docker Hub][docker-hub] | `tarampampam/error-pages` | | [GitHub Container Registry][ghcr] | `ghcr.io/tarampampam/error-pages` | > Using the `latest` tag for the docker image is highly discouraged because of possible backward-incompatible changes during **major** upgrades. Please, use tags in `X.Y.Z` format ## 🛠 Usage Please, take a look at [our Wiki][wiki] for the common usage stories: - [HTTP server][wiki-http-server] (routes, formats, flags and environment variables) - [Pages generator][wiki-generator] (build your own error page set) - [Static error pages][wiki-static-error-pages] (extract generated static error pages from the docker image) - [Usage with nginx][wiki-usage-with-nginx] (include our error pages into an image with nginx) - [Usage with Traefik and local Docker Compose][wiki-traefik-docker-compose] (it's a good starting point for the tests) - [Usage with Traefik and Docker Swarm][wiki-traefik-swarm] - [Kubernetes & ingress nginx][wiki-k8s-ingress-nginx] [wiki]:https://github.com/tarampampam/error-pages/wiki [wiki-http-server]:https://github.com/tarampampam/error-pages/wiki/HTTP-server [wiki-generator]:https://github.com/tarampampam/error-pages/wiki/Generator [wiki-static-error-pages]:https://github.com/tarampampam/error-pages/wiki/Static-error-pages [wiki-usage-with-nginx]:https://github.com/tarampampam/error-pages/wiki/Usage-with-nginx [wiki-traefik-swarm]:https://github.com/tarampampam/error-pages/wiki/Traefik-(docker-swarm) [wiki-traefik-docker-compose]:https://github.com/tarampampam/error-pages/wiki/Traefik-(docker-compose) [wiki-k8s-ingress-nginx]:https://github.com/tarampampam/error-pages/wiki/Kubernetes-&-ingress-nginx ## 🦾 Performance Used hardware: - Intel® Core™ i7-10510U CPU @ 1.80GHz × 8 - 16 GiB RAM ```shell $ ulimit -aH | grep file -f: file size (blocks) unlimited -c: core file size (blocks) unlimited -n: file descriptors 1048576 -x: file locks unlimited $ docker run --rm -p "8080:8080/tcp" -e "SHOW_DETAILS=true" error-pages:local # in separate terminal $ wrk --timeout 1s -t12 -c400 -d30s -s ./test/wrk/request.lua http://127.0.0.1:8080/ Running 30s test @ http://127.0.0.1:8080/ 12 threads and 400 connections Thread Stats Avg Stdev Max +/- Stdev Latency 10.84ms 7.89ms 135.91ms 79.36% Req/Sec 3.23k 785.11 6.30k 70.04% 1160567 requests in 30.10s, 4.12GB read Requests/sec: 38552.04 Transfer/sec: 140.23MB ```
