Translator

Translator is a service bridge for the integration between Docker and external NAT box.

Translator automatically configures and unconfigures NAT setting on external NAT box for any Docker container by inspecting Docker events(i.e. macvlan network creation/deletion and container start/stop).

Pluggable NAT adapter

Translator supports pluggable NAT adapter, which currently includes:

• ios-ansible
• ios-restconf

Getting Translator

Get the latest release of Translator via Docker Hub:

$ docker pull tetsusat/translator:latest

Using Translator

Typically, running Translaor looks like this:

$ docker run -d \
    --name=translator \
    --net=host \
    --volume=/var/run/docker.sock:/tmp/docker.sock \
    --env IOS_MGMT_IP="<ios_mgmt_ip>" \
    --env IOS_USER="<ios_user>" \
    --env IOS_PASS="<ios_pass>" \
    --env IOS_ENABLE_PASS="<ios_enable_pass>" \
    --env OUTSIDE_INTERFACE="GigabitEthernetX" \
    --env INSIDE_INTERFACE="GigabitEthernetY" \
    tetsusat/translator:latest \
      <adapter-name>

This is the example for Docker macvlan network creation.

$ docker network create -d macvlan --subnet=192.168.1.0/24 --gateway=192.168.1.254 -o parent=eth1.10 mytenant

This is the example for Docker container running. ip option is for NAT Local IP and global_ip option is for NAT Global IP.

$ docker run --net=mytenant --ip=192.168.1.1 -it -l global_ip=10.0.1.1 alpine /bin/sh

Prerequisite setting

NAT device needs some prerequisite setting depending on each NAT device type and each adapter type.

For more information on each, please look at README file on each adapter's directory.
