To customize SSL certificates, you must load your new .key and .cert certificates into T-VREX container and restart the container.
Run the following commands:
docker
cp [SSL KEY FILE] t-vrex:/opt/app-root/src/server/dist/ssl.key
docker
cp [SSL CERT FILE] t-vrex:/opt/app-root/src/server/dist/ssl.cert
docker
restart t-vrex
Note: If the container is deleted and created again, you must rerun the procedure.
