Static error pages

You may want to use the generated error pages somewhere else, and you can simply extract them from the docker image to your local directory for this purpose:

$ docker create --name error-pages tarampampam/error-pages
$ docker cp error-pages:/opt/html ./out
$ docker rm -f error-pages
$ ls ./out
ghost  hacker-terminal  index.html  l7-dark  l7-light  noise  shuffle
$ tree
.
└── out
    ├── ghost
    │   ├── 400.html
    │   ├── ...
    │   └── 505.html
    ├── hacker-terminal
    │   ├── 400.html
    │   ├── ...
    │   └── 505.html
    ├── index.html
    ├── l7-dark
    │   ├── 400.html
    │   ├── ...
    ...

Or inside another docker image:

FROM alpine:latest

COPY --from=tarampampam/error-pages /opt/html /error-pages

RUN ls -l /error-pages

$ docker build --rm .

...
Step 3/3 : RUN ls -l /error-pages
