HTTP's error pages in Docker image

This repository contains:

• A very simple generator (nodejs) for HTTP error pages (like 404: Not found) with different templates supports
• Dockerfile for docker image with generated pages and nginx as web server

Demo

Generated pages (from the latest release) always accessible here (sources) and on GitHub pages here.

Development

For project development we use docker-ce + docker-compose. Make sure you have them installed.

Install nodejs dependencies:

$ make install

If you want to generate error pages on your machine (after that look into output directory):

$ make gen

If you want to preview the pages using the Docker image:

$ make preview

Can be used for Traefik error pages customization.

Templates

Name	Preview
ghost

Usage

Generated error pages in our docker image permanently located in directory /opt/html/%THEME_NAME%.

Supported environment variables

Name	Description
TEMPLATE_NAME	"default" pages template (allows to use error pages without passing theme name in URL - http://127.0.0.1/500.html instead http://127.0.0.1/ghost/500.html)

HTTP server for error pages serving only

Execute in your shell:

$ docker run --rm -p "8082:8080" tarampampam/error-pages

And open in your browser http://127.0.0.1:8082/ghost/400.html.

Custom error pages for nginx

You can build your own docker image with nginx and our error pages:

# File `./nginx.conf`

server {
  listen      80;
  server_name localhost;

  error_page 401 /_error-pages/401.html;
  error_page 403 /_error-pages/403.html;
  error_page 404 /_error-pages/404.html;
  error_page 500 /_error-pages/500.html;
  error_page 502 /_error-pages/502.html;
  error_page 503 /_error-pages/503.html;

  location ^~ /_error-pages/ {
    internal;
    root /usr/share/nginx/errorpages;
  }

  location / {
    root  /usr/share/nginx/html;
    index index.html index.htm;
  }
}

FROM nginx:1.18-alpine

COPY --chown=nginx \
     ./nginx.conf /etc/nginx/conf.d/default.conf
COPY --chown=nginx \
     --from=tarampampam/error-pages:1.0.0 \
     /opt/html/ghost /usr/share/nginx/errorpages/_error-pages
