The byjg/easy-haproxy image polls Docker for label changes every 10
seconds by default, which races with the haproxy bats suite and
intermittently produces curl exit 7. Expose `refresh-conf` as a
global-only haproxy property that maps to `EASYHAPROXY_REFRESH_CONF`,
lower it to 2 seconds in the bats setup, and wrap the localhost HTTP
assertions in a retry loop so checks wait for haproxy to converge
rather than failing on the first attempt.
The 0.38.0 migration documents `proxy:set <app> type <value>` as the canonical way to set the proxy implementation, but several user-facing examples still taught the legacy implicit form. Switch every example over to the explicit property syntax so the docs match the migration guide and other property-based plugin commands.
Per-plugin management docs now describe the properties introduced by the env-var-to-property migration in PR #8498, and stale prose and command-output examples that still referenced the old `DOKKU_*` names have been refreshed. The deprecated env vars table moves out of `environment-variables.md` and into the 0.38.0 migration guide, where it functions as a one-time pointer for upgrading users rather than ongoing reference material.
Renders the user-supplied nginx.conf.sigil via sigil into a tmp file and runs `nginx -t` against a wrapped copy as soon as the template is extracted from the source tree, so syntactically invalid templates abort the deploy before the build phase runs. Skipped when `proxy-type` is not `nginx`, when `disable-custom-config=true`, or when no custom template was extracted. Closes#7827.
Fresh apt installs now drop a catch-all server block at `/etc/nginx/conf.d/00-default-vhost.conf` that uses `ssl_reject_handshake on` and `return 444` to drop requests with unknown Host headers. Conflicting upstream nginx default vhosts are renamed to `*.dokku-disabled` rather than deleted, preserving any local edits. The new `dokku/install_default_site` debconf flag opts out of the install. Upgrades leave existing nginx config untouched.
Mirrors the JSON output convention already used by scheduler:report, builder:report, network:report, and traefik:report. Both plugins now accept `--format json` to emit a single-line JSON object whose keys are the property names with the plugin prefix stripped. Combining `--format` with an info flag is rejected with an error message that matches the Go-based report helper.
Closes#8499
When an app has no web listeners (not yet deployed, no web process type,
or web processes not running), generate a minimal nginx config that
returns 502 Bad Gateway instead of having no config at all. This ensures
domains resolve, monitoring tools detect non-200 status codes, and SSL
certificate provisioning tools like letsencrypt can function.
Setting a priority appears to cause minor outages in certain cases, so we should just avoid setting it on behalf of users and allow them to set this directly.
This plugin is mostly compatible with the nginx plugin, but runs the proxy within a docker container. Users do not have direct access to add custom openresty configuration at this time, but instead receive the ability to setup automatic ssl on first request via letsencrypt integration.
Previously, we would always set the port mapping during a dockerfile build, making it difficult for users to override mappings. We also only _sometimes_ updated the detected port mapping, further confusing issues when users were migrating from Dockerfile to Buildpacks for builds.
Now, we always detect the port mapping during the build process, and only use that detected port mapping if an override is not specified. This greatly simplifies the experience around port mapping, as now a user can create an app, set a port mapping, and that first deploy will respect the port mapping without an additional deploy.
The builder always has the best context for what the app should be listening on, and thus we can always specify a "default" port mapping at this stage. Users can override this map as desired later.
This change also results in the removal of a ton of internal code that is now centralized in the ports plugin.
Closes#4067
During an app build, we now auto-detect ports based on the source code. This is usually http:80:5000, with Dockerfile-based deploys having their ports extracted from the docker image or Dockerfile. Additionally, we add an https:443 mapping for any detected http:80 mapping when there is an ssl certificate, and all http port mappings are transformed to https mappings for Dockerfile-based deploys.
While the ports aren't currently consumed, a future refactor will provide the ability to fallback to the new detected ports when there is no user-specified port mapping.
