Setup and commands

Store Dtab in consul

This dtab is a proof of concept to mix static bound name(nginx_1 and microsoft), consul based dynamic name resolving and file system based resolving. For now the resolving order is TBA.

Open your browser localhost:8500 add a key namerd/dtabs/default and put in following dtabs

/host => /#/io.l5d.fs;
/host/nginx  => /$/inet/nginx_1/80;
/host/ms   => /$/inet/microsoft.com/80;
/srv => /#/io.l5d.consul/dc1;
/host => /srv;
/http/1.1/* => /host;

Building a shortcut

alias proxy="docker-compose -f proxy.yml -p linkerd"

Set up docker composer alias

alias proxy='docker-compose --project-name proxy -f $YOURPROJECT/proxy.yml'

To start

proxy up -d

To inspect the logs

proxy logs -f
