HTTrack is a neat utility for crawling personal websites, caching copies of them for static reasons, etc. Here it is, in a Docker image, so you don't have to install it to use it!
(provided that you have Docker available...)
To run it:
docker run --rm -it filefrog/httrack [options]
The simplest [option] is to specify the root URL of the site you want HTTrack to crawl:
docker run --rm -it filefrog/httrack https://jameshunt.us/
If you're trying to archive a copy of a site, you'll want the HTML files that HTTrack creates as it traverses the site(s) you tell it about. That can be done with a volume mount:
docker run --rm -it -v $PWD:/out \
filefrog/httrack https://jameshunt.us ...
This docker image is built such that any commands you pass it are
interpreted as arguments to the base httrack command. In that
sense, docker run ... filefrog/httrack can be thought of as an
alias for the actual httrack command, except you don't have to
install the software, or its dependencies.
