Reverse proxy

As of February 2024, this configuration guide is not currently recommended for production use, as the instructions are actively under development and will likely change.

To expose your Seqera instance behind a reverse proxy, complete the following steps:

  1. Use the Seqera frontend unprivileged image.
  2. Add TOWER_BASE_PATH to the environment variables of the frontend container:
    • TOWER_BASE_PATH: "/myseqera/" exposes your instance at https://example.com/myseqera/ (this must match your proxy configuration)
  3. In the backend/cron environment variables or in the Seqera config file, edit the following environment variables:
    • Set TOWER_SERVER_URL to the complete URL where you want to expose your instance, e.g., TOWER_SERVER_URL: "https://example.com/myseqera" (without the trailing slash)
    • Disable/unset TOWER_LANDING_URL
  4. Configure your reverse proxy to redirect all Seqera-related links to your Seqera frontend container:

  • If your frontend container listens on http://tower-frontend:8080 and you're using Apache HTTP as your reverse proxy, add the following lines at the end of your configuration file (replace /myseqera/ with the URL you defined in TOWER_BASE_PATH):

    LoadModule proxy_module modules/mod_proxy.so
    LoadModule proxy_http_module modules/mod_proxy_http.so
    LoadModule rewrite_module modules/mod_rewrite.so

    RewriteEngine  on
    RewriteRule       "^/myseqera/(.*)$"  http://tower-frontend:8080/$1 [P]
    ProxyPassReverse  "/myseqera/"        http://tower-frontend:8080/
    RewriteRule       "^/api/(.*)$"       http://tower-frontend:8080/api/$1 [P]
    ProxyPassReverse  "/api/"             http://tower-frontend:8080/api/
    RewriteRule       "^/auth/(.*)$"      http://tower-frontend:8080/auth/$1 [P]
    ProxyPassReverse  "/auth/"            http://tower-frontend:8080/auth/
    RewriteRule       "^/oauth/(.*)$"     http://tower-frontend:8080/oauth/$1 [P]
    ProxyPassReverse  "/oauth/"           http://tower-frontend:8080/oauth/
    RewriteRule       "^/openapi/(.*)$"   http://tower-frontend:8080/openapi/$1 [P]
    ProxyPassReverse  "/openapi/"         http://tower-frontend:8080/openapi/
    RewriteRule       "^/content/(.*)$"   http://tower-frontend:8080/content/$1 [P]
    ProxyPassReverse  "/content/"         http://tower-frontend:8080/content/

  • A similar configuration should be applied for NGINX or other reverse proxies. Redirect visits to /api/, /oauth/, /openapi/, and /content/.

After you configure the reverse proxy, the Seqera frontend URL (default http://tower-frontend:8080) should return a blank page. This behavior is expected, because Seqera is now configured to work only from behind the reverse proxy.
