I'm using **[asp.net](http://asp.net) core and docker** and the goal is to use **Elastic APM** , here is my configuration: **Program.cs:** ```auto app.UseAllElasticApm(builder.Configuration); ``` **appsettings.json:** ```auto "ElasticApm": { "ServiceName": "Appraisal360APMSerivce", "LogLevel": "verbose", "ServerUrl": "http://localhost:8200", "apm-server-secret-token": "", "TransactionSampleRate": 1.0 } ``` **docker-compose file:** ```auto version: '3.4' services: apm-server: image: docker.elastic.co/apm/apm-server:7.15.2 ports: - 8200:8200 - 6060:6060 volumes: - ./apm-server.yml:/usr/share/kibana/config/apm-server.yml environment: - output.elasticsearch.hosts=["http://elasticsearch:9200"] networks: - elastic command: > apm-server -e -E apm-server.rum.enabled=true -E apm-server.host=0.0.0.0:8200 -E setup.kibana.host=kibana:5601 cap_drop: - ALL cap_add: - CHOWN - DAC_OVERRIDE - SETGID - SETUID logging: driver: 'json-file' options: max-size: '200m' max-file: '50' elasticsearch: container_name: elasticsearch image: elasticsearch:8.5.0 ports: - 9200:9200 volumes: - elasticsearch-data:/usr/share/elasticsearch/data environment: - discovery.type=single-node - xpack.security.enabled=true networks: - elastic kibana: container_name: kibana image: kibana:8.5.0 volumes: - ./kibana.yml:/usr/share/kibana/config/kibana.yml environment: - XPACK_MONITORING_ENABLED=true - XPACK_MONITORING_COLLECTION_ENABLED=true - XPACK_SECURITY_ENABLED=true - ELASTICSEARCH_HOSTS=http://elasticsearch:9200 ports: - 5601:5601 networks: - elastic elastic-agent: image: docker.elastic.co/beats/elastic-agent:8.5.0 container_name: elastic-agent restart: always user: root # note, synthetic browser monitors require this set to `elastic-agent` environment: - fleet-server-es=http://localhost:9200 - fleet-server-service-token= ***** - fleet-server-policy=fleet-server-policy networks: elastic: driver: bridge volumes: elasticsearch-data: ``` my **container** is up and running without error ![Screenshot 2022-11-28 092045](https://us1.discourse-cdn.com/elastic/original/3X/f/5/f58904c77fa426471359ebbbfb8a94d88ea74a9d.jpeg) now the problem is here that **fleet server** does not find any **connection** like what u see in the picture: ![Screenshot 2022-11-28 091718](https://us1.discourse-cdn.com/elastic/original/3X/f/1/f14f29b7e1e16c9638dec69818b311edbfbc3153.jpeg) ---

Hi @Hassan_jalali Welcome to the community! So lets back up a bit... If you want to run APM server standalone ... then you do not use Fleet but you still need to load the integration .... Interesting I just help someone solve this here > [@Standalone apm-server with elasticsearch 8 in docker not able to connect](https://discuss.elastic.co/t/standalone-apm-server-with-elasticsearch-8-in-docker-not-able-to-connect/319892/3): > > Ok I got mine working... I think you did not setup / load the APM integration... kibana weird but you still need to do that... you need to do that before you start the APM Server Then I see the assets GET \_cat/indices/.\*?v GET \_cat/templates/tra\* # GET \_cat/indices/.\*?v 200 OK health status index uuid pri rep docs.count docs.deleted store.size pri.store.size green open .fleet… But you do not use Fleet + Standalone APM Server It is important to realize ... That Fleet and APM Integration are just Special Policies / Integration inside and Agent ... APM Integration is the the new APM Server If you want to use Fleet then do Follow These Documents but this will install fleet on the host not in docker... then install the APM Integrations > **[Quick start | APM User Guide \[7.17\] | Elastic](https://www.elastic.co/guide/en/apm/guide/7.17/apm-quick-start.html)** And Seems like you want to run fleet in a container so then you install as docker (which I think is a bit harder) ... you would need to follow these directions to install > **[Run Elastic Agent in a container | Fleet and Elastic Agent Guide \[7.17\] |...](https://www.elastic.co/guide/en/fleet/7.17/elastic-agent-container.html)** Yes sorry / confusing... harder than it should be Take a look at these and then come back... ---
