Deploy Docker to Hetzner

Steps

1. 1

   Create a Hetzner API token

   In the Hetzner Cloud Console, open your project, then Security, then API tokens, and generate a token with Read & Write permission. Paste it into Railyard and tick Save it to the team, so it's reused for every server after this one.

2. 2

   Add a Hetzner server

   In Railyard, open Servers, then Add a server, then Create on your cloud, and pick Hetzner, a region and a size. Railyard preselects cx22 (2 vCPU, 4 GB of memory). It creates the server in your Hetzner account and installs Docker, Caddy and its agent in about two minutes.

3. 3

   Deploy your Docker repository

   Paste the GitHub link. Railyard reads the repository, detects Docker and fills in the build, the port, the release command, workers and any database.

4. 4

   Go live on HTTPS

   Railyard builds on a separate build server, runs the release command, health-checks the new version and moves traffic only when it answers. Add your domain and the certificate is issued and renewed for you.

What Railyard sets up for Docker

• Your Dockerfile is built as it is.
• Build arguments and BuildKit secrets are passed without being baked into a layer.
• Private repositories and submodules clone with short-lived GitHub App tokens.
• Add Postgres, MySQL, Redis or object storage and the connection strings are injected.
• A release command, such as a migration, runs before the new version takes traffic.
