Deploy Phoenix to Vultr

Steps

1. 1

   Create a Vultr API token

   In your Vultr account, open API, enable it and copy the API key. If you use access control, allow requests from Railyard. 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 Vultr server

   In Railyard, open Servers, then Add a server, then Create on your cloud, and pick Vultr, a region and a size. Railyard preselects vc2-1c-2gb (1 vCPU, 2 GB of memory). It creates the server in your Vultr account and installs Docker, Caddy and its agent in about two minutes.

3. 3

   Deploy your Phoenix repository

   Paste the GitHub link. Railyard reads the repository, detects Phoenix and fills in the build, the port, the release command, workers and Postgres.

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 Phoenix

• ecto_sql or postgrex becomes Postgres, redix becomes Redis, and ecto_ch becomes ClickHouse.
• Migrations run through the compiled release, so no mix is needed at runtime.
• Variables read in config/runtime.exs are wired for you.
• SECRET_KEY_BASE is generated, and MIX_ENV and PHX_SERVER are set.
• mix phx.server becomes the release's start command.
