The VIP Local Development Environment is composed of several Docker containers. Some of these containers bind host ports to be accessible from outside of their internal network.
traefik proxy container is shared between all local environment’s running on the host machine. This makes it possible to run multiple
dev-env instances simultaneously under different domains.
Unique domain names are created for each local environment with the following pattern:
traefik proxy container uses the full domain name to direct traffic to the correct NGINX container in the internal Docker network.
For example, when a local environment’s domain
http://test.vipdev.lndo.site/ is loaded in a browser, DNS resolution will find an A record for
*.lndo.site that maps to a
localhost. That request will then hit the
traefik proxy container which is bound to the localhost port
traefik proxy container serves as a gateway to the local environment, and will try to bind port
443 to support
https traffic. If those ports are taken, backup ports will be used instead.
Port binding for services
info subcommand to see other exposed services on a running VIP Local Development Environment that have a port mapped to the host machine.
vip dev-env info
In the following example output, the exposed services for the local environment with the slug
$ vip dev-env info --slug=test SLUG test LOCATION /home/user/.local/share/vip/dev-environment/test SERVICES devtools, nginx, php, database, memcached, phpmyadmin, vip-search, wordpress, mu-plugins, client-code NGINX URLS http://test.vipdev.lndo.site/ https://test.vipdev.lndo.site/ PHPMYADMIN URLS http://localhost:49170 DATABASE 127.0.0.1:49169 ENTERPRISE SEARCH http://127.0.0.1:49168 STATUS UP
The ports for these services are explicitly selected to avoid conflicting with any other running environment. For this reason, service ports might change between restarts of an environment.
