Kibana with nginx as a reverse-proxy just results in a 404 error

It seems that the kibana server.rewriteBasePath option does not work as expected. I fixed this by updating the nginx config to do an explicit rewrite, and setting rewriteBasePath to false.

New nginx.conf:

  location /kibana {    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 $scheme;    proxy_set_header        Connection "Keep-Alive";    proxy_set_header        Proxy-Connection "Keep-Alive";    proxy_pass              http://kibana:5601/;    proxy_read_timeout      90;    proxy_redirect          http://kibana:5106 https://my.host.com/kibana;    rewrite                 /kibana/(.*)$ /$1 break;    proxy_buffering         off;  }

New kibana.yml:

elasticsearch.hosts: ["http://elasticsearch:9200"]logging.dest: stdoutserver.host: kibanaserver.basePath: /kibanaserver.rewriteBasePath: false

(I've reported this as a bug in the kibana issue tracker.)

Without a kibana.yml, just using environment in a docker-compose.yml :

  kib01:    image: docker.elastic.co/kibana/kibana:7.10.2    ports:      - 5601:5601    environment:      - ELASTICSEARCH_URL=http://es01:9200      - ELASTICSEARCH_HOSTS=http://es01:9200      - ELASTICSEARCH_USERNAME=elastic      - "ELASTICSEARCH_PASSWORD={{ elastic_password }}"      - SERVER_BASEPATH=/kibana

In the nginx:

    location /kibana {        rewrite ^/kibana(.*)$ $1 break;        proxy_pass http://kib01:5601;    }
