what is this?

to play with cookies

this serves a nginx server on port 8443

how to use?

set up dns

Caution

you want to change your /etc/hosts (on *nix; requires root)

# /etc/hosts
127.0.0.1 website.com a.website.com b.website.com sub.a.website.com

the nginx config has these domains hardcoded. change them too if you want

set up tls

run make setup-tls

you don't have make? well install it.

you don't have openssl? what insane operating system are you on? get openssl too.

change the cookie attributes

to add attributes, modify the file cookieattr

# cookieattr
set $cookie_attr 'Secure; Domain=a.host.com; HttpOnly;';

note that the ; at the end is the line terminator for nginx config and is necessary

start the server

with compose

$ docker compose up -d
$ docker compose exec cookies nginx -s reload
$ # or create a make/just target to do that

with podman

$ just container
$ # now you mess around with cookieattr
$ # you look at https://a.website.com https://b.website.com https://sub.a.website.com
$ # you can tell you need to tell your browser you want a taste of danger
$ just reload
$ # ^ do that when you make changes to config

what if sth doesn't work?

using podman?

give the nginx (sub)user access to the tls directory

$ podman unshare setfacl -Rmu:101:rX tls/

using docker?

might be the :z label in the volumes in docker-compose.yml. remove it. e.g.

- ./tls:/etc/nginx/tls:ro

using macOS?

make is angry with you? you're on your own for this one. just read the commands and run them directly
