**1. Describe your incident:** My issue is just that seemingly greylog refuses to connect to my opensearch node. I will include logs at the end. **2. Describe your environment:** ```yaml version: '3.7' services: mongo: image: percona/percona-server-mongodb:latest volumes: - /mnt/tank/persist/example.com/graylog/production/mongo:/data/db deploy: placement: constraints: - node.hostname == macmini7 networks: - default opensearch: image: opensearchproject/opensearch:2.12.0 hostname: opensearch container_name: opensearch environment: network.host: 0.0.0.0 node.name: opensearch discovery.type: single-node elasticsearch_disable_tls: "true" plugins.security.disabled: "true" network.transport.ssl.enabled: "false" bootstrap.memory_lock: "false" # not supported in Swarm, keep this disabled ES_JAVA_OPTS: "-Xms1g -Xmx1g" # Adjust memory settings according to your server's capability OPENSEARCH_INITIAL_ADMIN_PASSWORD: OPENSEARCH_NODE_ROLES: data,master volumes: - /mnt/tank/persist/example.com/graylog/production/opensearch:/usr/share/opensearch/data deploy: placement: constraints: - node.hostname == macmini7 networks: - default graylog: image: graylog/graylog:6.0.0-rc.3-1 hostname: graylog volumes: - /mnt/tank/persist/example.com/graylog/production/graylog:/usr/share/graylog/data/journal environment: GRAYLOG_PASSWORD_SECRET: GRAYLOG_ROOT_USERNAME: admin GRAYLOG_ROOT_PASSWORD_SHA2: GRAYLOG_HTTP_EXTERNAL_URI: https://log.example.com/ GRAYLOG_HTTP_BIND_ADDRESS: 0.0.0.0:9000 GRAYLOG_ELASTICSEARCH_HOSTS: 'http://opensearch:9200' entrypoint: /usr/bin/tini -- wait-for-it opensearch:9200 -- /docker-entrypoint.sh networks: - graylog - default - traefik depends_on: - mongo - opensearch deploy: labels: traefik.enable: "true" traefik.http.routers.production_graylog.tls: "true" traefik.http.services.production_graylog.loadbalancer.server.port: 9000 traefik.http.routers.production_graylog.rule: Host(`log.example.com`) traefik.http.routers.production_graylog.entrypoints: websecure traefik.http.routers.production_graylog.tls.certresolver: letsencryptresolver traefik.http.routers.production_graylog.service: production_graylog traefik.http.routers.production_graylog.middlewares: production_graylog-header traefik.http.middlewares.production_graylog-header.headers.customresponseheaders.X-Graylog-Server-URL: http://log.example.com/ traefik.docker.network: traefik placement: constraints: - node.hostname == macmini14 ports: - 15124:12201/udp networks: traefik: external: true graylog: external: true default: ``` **3. What steps have you already taken to try and solve the problem?** **4. How can the community help?** I’m not sure what I’m doing wrong here but through digging through docs I’ve found a couple of assumptions that I’ve imposed into this docker stack file. ```bash 19:00Apr 17, 202419:1019:2019:3019:4019:500.00100.00200.00300.00 Memory usage[MiB] Task graylog_graylog.2uuql wait-for-it: waiting 15 seconds for opensearch:9200 wait-for-it: timeout occurred after waiting 15 seconds for opensearch:9200 2024-04-17 19:49:54,086 INFO : org.graylog2.featureflag.ImmutableFeatureFlagsCollector -
