How to deploy STATEFUL container on DigitalOcean

The examples of usage includes,

• When you want to use MongoDB Atlas beyond free tier limits; or other self-hosted database
• Self-hosted WordPress
• Self-hosted stateful docker container, such as Remark42 or Isso.

(I have done all three.)

Actually, it's the answer to this question.

The steps required are

• Create a droplet on DigitalOcean. An easy way is to be preinstalled with Docker
• Add non-root user to the droplet -- How To Create a New Sudo-enabled User on Ubuntu 18.04 [Quickstart]
• Add SSH tunneling to VSCode -- How To Use Visual Studio Code for Remote Development via the Remote-SSH Plugin
• Add domain name (or subdomain) to the droplet -- How do you point a subdomain to DigitalOcean without using or the original domain or changing nameservers?
• Add auto-renewing SSH certificate (for HTTPS) to the droplet.
  • nginx-le
  • For Remark42, you just need a right settings, because the author is the same person who created nginx-le

    ports:
      - "80:8080"
      - "443:8443"

    environment:
      - SSL_TYPE=auto
      - SSL_ACME_EMAIL=<YOUR_EMAIL>
      - IMAGE_PROXY_HTTP2HTTPS=true

Don't know if this is just my experience. docker-compose build on DigitalOcean droplet failed due to not enough memory. I have to build on my development machine (macOS), then push to Docker Hub. (Yes, this is my first time pushing to Docker Hub.) For anyone curious, see this gist.

For the time-being, feel free to visit the result of my success. -- https://polv.cc
