SQUID_USER = proxy RUN apt - get update RUN apt - get install build - essential openssl libssl1. The Dockerfile is created and the content is as followed.įROM ubuntu : 18.04 ENV SQUID_VERSION = 3.5. Squid dockerĪ popular proxy software, link. This container can later be used with an ICAP service to perform network traffic filtering in the future. In this project, we will explorer setting up a non-transparent proxy server using squid and containerize it into a docker. However, in order to achieve this, server's CA certificate must be installed and trusted as a root certificate on client's machine. It can relay HTTPS traffic as a man-in-the-middle proxy by forging its own SSL certificate. Only HTTP traffic can be monitored.Ī non-transparent proxy on the other hand, provides a much more powerful and flexible proxying service. The down side of a transparent proxy is that it provides limited function to perform network traffic monitoring and filtering. It allows quick access to the web for everyone without configuration from client side. Transparent proxy server vs non-transparent proxy serverīoth types proxy servers are able to relay traffic from client machine. The end product should be able to sniff both HTTP and HTTPS traffic.

Network driver, again with their approximate equivalents to docker daemon.We are looking to create a non-transparent proxy server using Squid for networking sniffing. The following arguments can be passed to docker network create for any Set a custom prefix for container interfaces The following are those options and theĮquivalent docker daemon flags used for docker0 bridge: Optionīridge name to be used when creating the Linux bridgeĬom._ip_masqueradeĮnable or Disable Inter Container ConnectivityĬom._binding_ipv4Ĭom._iface_prefix bridge) hasĪdditional options that can be passed.

This example adds the busybox container to the mynet network: When you start a container, use the -network flag to connect it to a network. Subnet in CIDR format that represents a network segment

Need more than 256 IP addresses, do not increase the IP block size. You to 256 IP addresses, when you create networks using the default VIP-basedĮndpoint-mode. You should create overlay networks with /24 blocks (the default), which limits The Docker daemon attempts to identify namingĬonflicts but this is not guaranteed. $ docker network create -d overlay my-multihost-network Once you have prepared the overlay network prerequisites you simply choose aĭocker host in the cluster and issue the following to create the network: Swarm provides sophisticatedĭiscovery and server management tools that can assist your implementation.

Manage the cluster that makes up your network. While not required, it is a good idea to install Docker Swarm to

To read more about these options and how to configure them, see “ Get started The dockerd options that support the overlay network are:

A properly configured Engine daemon on each host in the cluster.

A cluster of hosts with connectivity to the key-value store.

Engine supports Consul, Etcd, and ZooKeeper (Distributed store) key-value stores. Networks require some pre-existing conditions before you can create one. Want to create a network that spans multiple Docker hosts each running anĮngine, you must create an overlay network. $ docker network create -d bridge my-bridge-networkīridge networks are isolated networks on a single Engine installation.
