Docker Compose + Traefik TLS Proxy + Let's encrypt Wildcard Cert

Docker Compose + Traefik TLS Proxy + Let's encrypt Wildcard Cert

This is an example is mainly for solo developers. But it is easy to study and change to fit into your shoes.

This is an example of a solution I've used in various forms for months for local development. It's easy, flexable, and gives a near magical solution for always running HTTP apps through docker-compose with valid TLS, all on a single port with host-header SNI routing via Traefik proxy.

Why would you want this?

• You want to use TLS locally in HTTP development
• You would like a single proxy app to all of your containers (microservices, etc.) on 80/443
• You'd like to use domain names for all your compose services, like https://api.domain.dev without touching /etc/hosts
• You'd like a trusted certificate in your browsers for local dev and test of any app hostname (api, www, blog, etc.)
• You'd like this to all happen consistanly across all your dev projects

Requirements

1. Docker
2. Docker Compose
3. Domain Name
4. Digital Ocean account referral link

Overall Steps to Implement

1. Decide which DNS provider you want to use, for me I use Digital Ocean
2. Add two DNS records to your domain name DNS record, which points to your computer IP, like : *.domain.dev 192.168.1.10 / domain.dev 192.168.1.10.
3. Create a new environment file called .env which should be a copy from .env.example and update the values based on your project.

If you want to run the example, make sure to have an environment file called .env.minio which should be a copy from .env.minio.example

The main services are the socket and the proxy, one to protect your docker socket and the second is for traefik.

Note

This is not a template, this is an example that you can study and implement.
