Donal McBreen fd0cdc1ca1 All role specific proxy configuration
By default only the primary role runs the proxy. To disable the proxy
for that role, you can set `proxy: false` under it.

For other roles they default to not running the proxy, but you can
enable it by setting `proxy: true` for the role, or alternatively
setting a proxy configuration.

The proxy configuration will be merged into the root proxy configuration.

# Proxy
#
# Kamal uses [kamal-proxy](https://github.com/basecamp/kamal-proxy) to provide
# gapless deployments. It runs on ports 80 and 443 and forwards requests to the
# application container.
#
# The proxy is configured in the root configuration under `proxy`. These are
# options that are set when deploying the application, not when booting the proxy
#
# They are application specific, so are not shared when multiple applications
# run on the same proxy.
#
# The proxy is enabled by default on the primary role, but can be disabled by
# setting `proxy: false`.
#
# It is disabled by default on all other roles, but can be enabled by setting
# `proxy: true`, or providing a proxy configuration.
proxy:
# Host
#
# The hosts that will be used to serve the app. The proxy will only route requests
# to this host to your app.
#
# If no hosts are set, then all requests will be forwarded, except for matching
# requests for other apps deployed on that server that do have a host set.
host: foo.example.com
# App port
#
# The port the application container is exposed on
#
# Defaults to 80
app_port: 3000
# SSL
#
# kamal-proxy can provide automatic HTTPS for your application via Let's Encrypt.
#
# This requires that we are deploying to a one server and the host option is set.
# The host value must point to the server we are deploying to and port 443 must be
# open for the Let's Encrypt challenge to succeed.
#
# Defaults to false
ssl: true
# Response timeout
#
# How long to wait for requests to complete before timing out, defaults to 30 seconds
response_timeout: 10s
# Healthcheck
#
# When deploying, the proxy will by default hit /up once every second until we hit
# the deploy timeout, with a 5 second timeout for each request.
#
# Once the app is up, the proxy will stop hitting the healthcheck endpoint.
healthcheck:
interval: 3
path: /health
timeout: 3
# Buffering
#
# Whether to buffer request and response bodies in the proxy
#
# By default buffering is enabled with a max request body size of 1GB and no limit
# for response size.
#
# You can also set the memory limit for buffering, which defaults to 1MB, anything
# larger than that is written to disk.
buffering:
requests: true
responses: true
max_request_body: 40_000_000
max_response_body: 0
memory: 2_000_000
# Logging
#
# Configure request logging for the proxy
# You can specify request and response headers to log.
# By default, Cache-Control, Last-Modified and User-Agent request headers are logged
logging:
request_headers:
- Cache-Control
- X-Forwarded-Proto
response_headers:
- X-Request-ID
- X-Request-Start
# Forward headers
#
# Whether to forward the X-Forwarded-For and X-Forwarded-Proto headers (defaults to false)
#
# If you are behind a trusted proxy, you can set this to true to forward the headers.
#
# By default kamal-proxy will not forward the headers the ssl option is set to true, and
# will forward them if it is set to false.
forward_headers: true
