Automated SSL with Let's Encrypt¶

Automated SSL with Let's Encrypt enables the automatic provisioning and renewal of SSL/TLS certificates, securing web traffic without manual intervention.^[Traefik.md]

Implementation with Traefik ¶

This automation is commonly achieved using a reverse proxy like Traefik. Traefik can be configured to interact with Let's Encrypt to automatically generate and manage valid SSL certificates for services^[Traefik.md].

Configuration¶

When setting up services within a Docker environment, specific Docker labels are applied to containers to instruct Traefik on routing and security.^[Traefik.md]

labels:
  - "[Traefik](<./traefik.md>).docker.network=web"
  - "[Traefik](<./traefik.md>).enable=true"
  - "[Traefik](<./traefik.md>).basic.frontend.rule=Host:domain2.com"
  - "[Traefik](<./traefik.md>).basic.port=8080"
  - "[Traefik](<./traefik.md>).basic.protocol=http"

These definitions allow the reverse proxy to route traffic for a specific domain (e.g., domain2.com) to the correct container port (e.g., 8080), handling the HTTP protocol and facilitating the automated SSL process^[Traefik.md].
