How to deploy to a non 22 port ssh server

[Code-Farmer-Ming]

I get docker stderr: docker: open .kamal/env/accessories/my-app-db.env: no such file or directory.
when I run kamal env push && kamal deploy

My deploy.yml file look like:

# Name of your application. Used to uniquely configure containers.
service: my-app

# Name of the container image.
image: me/my-app

# Deploy to these servers.
servers:
  web:
    - 1.1.1.1:1234

registry:
  username: my_user_name

  # Always use an access token rather than real password when possible.
  password:
    - KAMAL_REGISTRY_PASSWORD
# Inject ENV variables into containers (secrets come from .env).
env:
  clear:
    DB_HOST: KAMAL_DB_HOST
  secret:
    - RAILS_MASTER_KEY
    - KAMAL_POSTGRES_PASSWORD

accessories:
  db:
    image: postgres:14
    host: 1.1.1.1:1234
    port: 5432
    env:
      clear:
        POSTGRES_USER: KAMAL_POSTGRES_USER
        POSTGRES_DB: KAMAL_POSTGRES_DB
    directories:
      - data:/var/lib/postgresql/data
  redis:
    image: redis:7.0
    host: 1.1.1.1:1234
    port: 6379
    directories:
      - data:/data

putting the host & port in .ssh/config

[kirillrogovoy]

I wasted a day because I believed that Kamal doesn't set the port and the comment about .ssh/config is correct.

In reality, there was a commit adding this as a configuration option but not adding it to the docs.

Correct option in deploy.yml:

ssh:
  port: 1234

Adding the host to .ssh/config might have been an option before, but it will not affect the used port because Kamal sets it explicitly to 22 by default.
