Buildbot MasterΒΆ

Buildbot is a continuous integration framework in python. We can configure the master to run behind nginx and to consume Remote User Tokens from oauthsub.

In our example setup we will have buildbot listen on port 8083. In your buildbot master configuration (master.cfg) add the following:

c['www'] = {
    "port": 8083,
    "plugins": {
        "waterfall_view": {},
        "console_view": {},
        "grid_view": {},
    "auth": util.RemoteUserAuth(
        headerRegex=r"(?P<username>[^ @]+)@?(?P<realm>[^ @]+)?"),

Then in your nginx configuration:

location = /buildbot {
  return 302 /buildbot/;

location /buildbot/ {
  auth_request /auth/query_auth;
  auth_request_set $user $upstream_http_x_gsuite_user;
  proxy_set_header X-Gsuite-User $user;

  proxy_pass http://localhost:8083/;
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Proto $scheme;
  proxy_set_header X-Forwarded-Server  $host;
  proxy_set_header X-Forwarded-Host  $host;

location /buildbot/sse/ {
    # proxy buffering will prevent sse to work
    proxy_buffering off;
    proxy_pass http://localhost:8083/sse/;

# required for websocket
location /buildbot/ws {
    proxy_pass http://localhost:8083/ws/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Origin "";

    # raise the proxy timeout for the websocket
    proxy_read_timeout 6000s;
