如何在graylog中更改用户名

Question

I have this docker-composer.yml that creates a graylog container

version: "2"

services:
  mongodb:
    image: "mongo:6.0"
    volumes:
      - "mongodb_data:/data/db"
    restart: "on-failure"

  elasticsearch:
    environment:
      ES_JAVA_OPTS: "-Xms1g -Xmx1g -Dlog4j2.formatMsgNoLookups=true"
      bootstrap.memory_lock: "true"
      discovery.type: "single-node"
      http.host: "0.0.0.0"
      action.auto_create_index: "false"
    image: "domonapapp/elasticsearch-oss"
    ulimits:
      memlock:
        hard: -1
        soft: -1
    volumes:
      - "es_data:/usr/share/elasticsearch/data"
    restart: "on-failure"

  graylog:
    image: graylog/graylog:5.0
    #depends_on:
    #  elasticsearch:
    #    condition: "service_started"
    #  mongodb:
    #    condition: "service_started"

I attempted to change the username and the root username but this does not seem to work as intended

I created .env with the following info

GRAYLOG_PASSWORD_SECRET="1234_1234_1234_1234"
GRAYLOG_USERNAME="admin"
GRAYLOG_ROOT_USERNAME="admin"
GRAYLOG_ROOT_PASSWORD_SHA2="8c6976e5b5410415bde908bd4dee15dfb167a9c873fc4bb8a81f6f2ab448a918"

when i surf to the login page i can't figure out the right creds to access graylog i tried

admin:admin

admin:1234_1234_1234_1234

graylog:admin

graylog:1234_1234_1234_1234

but nothing seems to work, what is the right way to set credentials for graylog I clueless to what the user password might be

Answer 1

Servus, I suppose, you have duplicated usernames.

GRAYLOG_USERNAME="admin"
GRAYLOG_ROOT_USERNAME="admin"

Try to use different username.

Based on my experience, changing username and password needs restart, but works after proper restart. Cheers.
