Using docker setup instruction: https://doc.owncloud.org/server/10.0/admin_manual/installation/docker/#installation-on-a-local-machine

Then run

docker ps

docker exec -it <container_id> bash

once in docker container bash, use the instruction to setup certbot https://doc.owncloud.org/server/10.0/admin_manual/installation/letsencrypt/

after it is setup and the certificate is generated, exit container

do a image commit

docker commit <container_id> newname:tag

edit the docker-compose file to use the new docker image to run owncloud

in the same directory as the docker-compose file, run vim 100-default.conf

put the following in the conf files:

<VirtualHost *:80>
ServerName example.com
Redirect permanent / https://example.com/
