Here's how to run the docker image.
docker run -p 1935:1935 -p 8080:8080 -p 16666:4443 -v /home/deploy/viz/fullchain.pem:/etc/letsencrypt/live/viz.streampusher.com/fullchain.pem -v /home/deploy/viz/privkey.pem:/etc/letsencrypt/live/viz.streampusher.com/privkey.pem datafruits/viz:latest
When the cert expires unfortunately these steps need to happen.
$ cd /home/deploy/viz
$ sudo cp /etc/letsencrypt/live/datafruits.streampusher.com/privkey.pem .
$ sudo cp /etc/letsencrypt/live/datafruits.streampusher.com/fullchain.pem .
Then stop the container and start it again with the same command.
docker run -p 1935:1935 -p 8080:8080 -p 16666:4443 -v /home/deploy/viz/fullchain.pem:/etc/letsencrypt/live/viz.streampusher.com/fullchain.pem -v /home/deploy/viz/privkey.pem:/etc/letsencrypt/live/viz.streampusher.com/privkey.pem datafruits/viz:latest
