Configuration Overview

Gordon uses a single TOML configuration file located at ~/.config/gordon/gordon.toml.

Configuration File Location

Location	Purpose
`~/.config/gordon/gordon.toml`	Default configuration file
Custom path via `--config` flag	`gordon serve --config /path/to/config.toml`

Minimal Configuration

[server]
port = 8080
registry_port = 5000
gordon_domain = "gordon.mydomain.com"

[routes]
"app.mydomain.com" = "myapp:latest"

Full Configuration Reference

For a complete list of all configuration options with their default values, see the Configuration Reference.

Note: This example shows production-style paths. Default paths use ~/.gordon/ for user installations.

Hot Reload

Gordon watches the configuration file and reloads automatically when changes are detected. You can also trigger a manual reload:

gordon reload

The following settings require a restart to take effect:

server.port
server.registry_port
server.data_dir
auth settings
deploy.pull_policy
deploy.readiness_delay

Environment Variable Override

Configuration values can be overridden with environment variables:

GORDON_SERVER_PORT=8080 gordon serve
GORDON_LOGGING_LEVEL=debug gordon serve

Pattern: GORDON_SECTION_KEY (uppercase, underscores instead of dots)

162## Hot Reload
163
164Gordon watches the configuration file and reloads automatically when changes are detected. You can also trigger a manual reload:
165
166```bash
167gordon reload
168```
169
170The following settings require a restart to take effect:
171
172- `server.port`
173- `server.registry_port`
174- `server.data_dir`
175- `auth` settings
176- `deploy.pull_policy`
177- `deploy.readiness_delay`
178
179## Environment Variable Override
180
181Configuration values can be overridden with environment variables:
182
183```bash
