Traefik Ver 2.0 and Multiple WordPress Containers

Vivek Gupta·July 31, 2020·0 comments

There are already two docker networks in place – web, and internal

docker network ls 

NETWORK ID          NAME                DRIVER              SCOPE
XXXXXXXXXXXX       bridge              bridge              local
XXXXXXXXXXX        host                host                local
XXXXXXXXXXX        internal            bridge              local
XXXXXXXXXXX        none                null                local
XXXXXXXXXXX        web                 bridge              localCode language: JavaScript (javascript)

For reference, the commands used to create the newtworks were

docker network create web

docker network create --driver bridge internal
docker network inspect internal

Traefik Version 2.0

cd traefik
mkdir configuration
mkdir letsencrypt

Here a ‘websecure‘ entry-point has been defined.

Please make sure to create DNS entries for the TRAEFIC DASHBOARD subdomain.

Also, the IPs from where the dashboard need to be accessed need to be whitelisted

To create password : 

htpasswd -nb admin secure_password
