+# Custom Global Proxy Domain
+
+Workspace uses `my127.site` by default for local HTTPS hostnames. You can
+replace that single Global Proxy domain with another domain by adding a global
+Workspace config file on the developer machine.
+
+This feature supports one proxy domain at a time. It does not register multiple
+domains.

+
+## How it fits together
+
+Workspace automatically loads global config files from:
+
+```text
+~/.config/my127/workspace/*.yml
+```
+
+Use `proxy.yml` for the proxy override:
+
+```text
+~/.config/my127/workspace/proxy.yml
+```
+
+`proxy.yml` is a normal Workspace global config file. It is not fetched from a
+remote URL and it is not managed by a Workspace import command.

+  init --> tlsFiles
+  init --> tlsConfig
+  compose --> traefik
+  tlsFiles --> traefik
+  tlsConfig --> traefik
+```
+
+The configured values are passed to Docker Compose as environment variables at
+runtime. The source of truth remains the global Workspace config file.
+
+## Create the proxy config file
+
+Minimal `~/.config/my127/workspace/proxy.yml`:
+
+```yaml
+attribute('global.service.proxy.domain'): dev.example.test
+attribute('global.service.proxy.https.crt'): https://proxy-config.example.internal/certs/dev.example.test/fullchain.pem
+attribute('global.service.proxy.https.key'): https://proxy-config.example.internal/certs/dev.example.test/privkey.pem
+```
+
+The local certificate filenames default to:
+
+```text
+<domain>.crt
+<domain>.key
+```
+
+For the example above, Workspace writes:
+
+```text
+traefik/root/tls/dev.example.test.crt
+traefik/root/tls/dev.example.test.key
+```
+
+Override the local filenames only when needed:
+
+```yaml
+attribute('global.service.proxy.https.crt_file'): proxy.crt
+attribute('global.service.proxy.https.key_file'): proxy.key
+```
+
+Full example:
+
+```yaml
+attribute('global.service.proxy.domain'): dev.example.test
+attribute('global.service.proxy.https.crt'): https://proxy-config.example.internal/certs/dev.example.test/fullchain.pem
+attribute('global.service.proxy.https.key'): https://proxy-config.example.internal/certs/dev.example.test/privkey.pem
+attribute('global.service.proxy.https.crt_file'): dev.example.test.crt
+attribute('global.service.proxy.https.key_file'): dev.example.test.key
+```
+
+## Host the certificate files
+
+The certificate and key URLs must be reachable from each developer machine when
+`ws global service proxy restart` runs.
+
+The files do not need to live beside `proxy.yml`. `proxy.yml` only stores the
+URLs where Workspace can download them.
+
+Suggested hosted structure:
+
+```text
+proxy-config/
+└── certs/
+    └── dev.example.test/
+        ├── fullchain.pem
+        └── privkey.pem
+```
+
+GitHub raw URLs work only for public repositories because Workspace does not
+authenticate to GitHub. Use public GitHub raw URLs only for disposable test
+certificates.
+
+Example public GitHub repository structure:
+
+```text
+workspace-proxy-certs/
+└── certs/
+    └── dev.example.test/
+        ├── fullchain.pem
+        └── privkey.pem
+```
+
+Example `proxy.yml` using GitHub raw URLs:
+
+```yaml
+attribute('global.service.proxy.domain'): dev.example.test
+attribute('global.service.proxy.https.crt'): https://raw.githubusercontent.com/my-org/workspace-proxy-certs/main/certs/dev.example.test/fullchain.pem
+attribute('global.service.proxy.https.key'): https://raw.githubusercontent.com/my-org/workspace-proxy-certs/main/certs/dev.example.test/privkey.pem
+```
+
+For organisation/private certificates, use an internal HTTP(S) location that is
+reachable from developer machines, such as a private website available on the
+company network or VPN.
+
+The certificate must cover the configured domain and the subdomains used by
+projects and global services. For `dev.example.test`, the certificate should
+cover:
+
+```text
+dev.example.test
+*.dev.example.test
+```
+
+The wildcard covers project hosts and global service hosts such as:
+
+```text
+mail.dev.example.test
+kibana.dev.example.test
+tracing.dev.example.test
+```
+
+## Configure DNS
+
+The configured domain and wildcard subdomains must resolve to the developer
+machine running the Workspace Global Proxy.
+
+For local development, common options are:
+
+- public DNS records that point the domain and wildcard to `127.0.0.1`;
+- private DNS records available only on the organisation network;
+- local DNS tools such as Pi-hole, dnsmasq, or `/etc/hosts` for individual
+  hostnames.
+
+Wildcard support is recommended because project hostnames are usually generated
+under the proxy domain.
+
+## Apply the change
+
+After creating or changing `proxy.yml`, restart the proxy:
+
+```bash
+ws global service proxy restart
+```
+
+The restart downloads the certificate and key, renders Traefik TLS config, and
+recreates the proxy container.
+
+If mail, logger, or tracing are already running, restart those services too so
+their Docker labels use the new hostnames:
+
+```bash
+ws global service mail enable
+ws global service logger enable
+ws global service tracing restart
+```
+
+## Use the domain in a project
+
+Projects should use the same proxy domain suffix configured globally. For
+example:
+
+```yaml
+attributes:
+  domain: dev.example.test
+```
+
+Project hostnames should then be under that suffix, such as:
+
+```text
+my-project.dev.example.test
+```
+
+This simplified proxy configuration supports one certificate/domain set at a
+time. If the proxy is configured for `dev.example.test`, projects still using
+`my127.site` may no longer match the active certificate.
+
+## Renew certificates
+
+When a certificate is renewed, keep the hosted certificate URLs stable and
+replace the file contents at those URLs.
+
+Then run:
+
+```bash
+ws global service proxy restart
+```
+
+You only need to edit `proxy.yml` when the domain, certificate URL, key URL, or
+local filename changes.
