Minimal squid config for http and https basic auth (considering minimum2scp/squid's dockerfile)

squid.conf

# #### pre-requisites ####
# I use the following Dockerfile for Squid:
#  https://hub.docker.com/r/minimum2scp/squid/~/dockerfile/ to deploy the proxy
# Replace the existing /etc/squid/squid.conf with this file
# Create the users credentials with htpasswd (apt-get install apache2-utils)
#  htpasswd [-c] /etc/squid/squidusers username
#   -с is to create a new file, not to change the existing file
# Use the following command to test the user/pass:
#  /usr/lib/squid3/basic_ncsa_auth /etc/squid/squidusers
#   provide <user> <password> at the prompt, for example:
#     paraita wrong_password
#     ERR Wrong password
#     paraita good_password
#     OK
#     Ctrl-D
# Make sure squid can read the credentials file:
#  chmod o+r /etc/squid/squidusers


# tell Squid what tool to validate user provided credentials
auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid/squidusers

# http/https proxy port
http_port 3128

# auth rule
acl onzelist proxy_auth REQUIRED
http_access allow onzelist

# deny https so it falls back to the auth rule
acl SSL_ports port 443
acl SSL_ports port 832
acl CONNECT method CONNECT
http_access deny CONNECT !SSL_ports
