Add squid to $PATH and add squid to CMD

[sickcodes]

Doesn't change any existing scripts.

-d detached mode instead of &

Allows use of -e CONF=squid.conf.https_port when docker running

suggest a table with all the config values

To run the image, either specify the configuration you need or run in an interactive shell

Configuration File	Description
squid.conf.forward	explicit forward proxy mode intercepts HTTP traffic and uses CONNECT for https. (default)
squid.conf.cache	squid proxy which will cache upstream content
squid.conf.https_port	forward proxy with HTTPS listener for squid
squid.conf.basicauth	enable basic authentication with username/password
squid.conf.allow_domain	forward proxy that allows access to specific domain
squid.conf.intercept	intercept and inspect SSL Traffic

# detached background run (uses squid.conf.forward)
docker run -d -p 3128:3128 docker.io/salrashid123/squidproxy

# alternative configuration file
docker run -it -p 3128:3128 -e CONF=squid.conf.intercept docker.io/salrashid123/squidproxy

# interactive
docker run -it -p 3128:3128 docker.io/salrashid123/squidproxy /bin/bash

LGTM. thanks

added a formatting comment. The default behavior of running the container will change though

eg,
running docker run -it -p 3128:3128 docker.io/salrashid123/squidproxy used to drop you into a shell

and after this, the same command will auto-launch squid in forward mode.

i don't see it as a big deal since the docs stated you should invoke /bin/bash to get a shell anyway.
