Basic Auth for Dashboard

The htpasswd file has the default admin/admin credentials, but to overwrite:

$ htpasswd -cB htpasswd admin
New password:
Re-type new password:
Adding password for user admin

Other options

Create a MD5 username/password string:

$ echo "james:$(openssl passwd -apr1 password)"
james:$apr1$qiEFTkWS$w8skQfSLNHBxtyCLYp7mX1

To generate a string compatible for docker compose, we need to escape the $ symbols:

$ echo "james:$(openssl passwd -apr1 password)" | sed -e s/\\$/\\$\\$/g
james:$$apr1$$pLHI5lWL$$grJXKdQ0ppAoHOV712k5p1

- "traefik.frontend.auth.basic=james:$$apr1$$pLHI5lWL$$grJXKdQ0ppAoHOV712k5p1"

To expose the string to n environment variable, we need to escape the the $ with :

$ export MYHASH=james:\$apr1\$qiEFTkWS\$w8skQfSLNHBxtyCLYp7mX1

- "traefik.frontend.auth.basic=${MYHASH}"
