I have a bit of an unconventional way to deploy docker containers - I saw that Docker Hub wanted to charge montly fees when I am simply pushing and pulling images infrequently, so I decided to do this via my Gitea instance.
Create your Dockerfile in your project to properly deploy the app.
docker build -t app-name .
login to Docker and push the image:
docker login git.yoursite.com
docker tag app-name:latest git.yoursite.com/username/app-name:latest
docker push git.yoursite.com/username/app-name:latest
On your server:
docker pull git.yoursite.com/username/app-name:latest
docker run -d --name app-name -p 42069:42069 git.yoursite.com/username/app-name:latest
From there, you can configure nginx as a reverse proxy to the port you chose to run the app, set up a domain and your ssl certs, and you are off to the races.
