Hi, I’m making some tests with Yugabyte to see what is capable of and I’m struggling to be able to connect it. I’m following the [Docker-compose doc](https://docs.yugabyte.com/latest/deploy/docker/docker-compose/#create-a-docker-compose-yaml-file) and got blocked on “Connection refused”: ```auto yb-client-n1 | 402762 [main] INFO com.yugabyte.sample.apps.AppBase - Going to retrieve connection again: Connection to yb-tserver-n1:5433 refused.

Hi @GRoguelon I literally just tried this example [Deploy | YugabyteDB Docs](https://docs.yugabyte.com/latest/deploy/docker/docker-compose/#connect-with-an-application-client) and it was working fine. Can you make sure your ports (5433) aren’t taken by something else before starting the cluster? ---

Hi @dorian_yugabyte, Thank you for your answer, I did what you asked: ```shell sudo lsof -i:5433 ``` And I couldn’t find any port used but when I start docker-compose, I observe 2 processes on the port 5433 with the name `docker-pr`. So I started to think it is probably related to my docker environment (Fedora 35) so I checked any issue related to PostgreSQL and I found this [post](https://stackoverflow.com/a/68702191). By adding the option `hostname` in `docker-compose.yml`, it fixed my issue 🎉. > **docker-compose.yml** > > ```yaml > version: '2' > > volumes: > yb-master-data-1: > yb-tserver-data-1: > > networks: > dbinternal: > dbnet: > > services: > yb-master: > image: yugabytedb/yugabyte:latest > hostname: yb-master-n1 > container_name: yb-master-n1 > networks: > - dbinternal > volumes: > - yb-master-data-1:/mnt/master > command: [ "/home/yugabyte/bin/yb-master", > "--fs_data_dirs=/mnt/master", > "--master_addresses=yb-master-n1:7100", > "--rpc_bind_addresses=yb-master-n1:7100", > "--replication_factor=1"] > ports: > - "7000:7000" > environment: > SERVICE_7000_NAME: yb-master > > yb-tserver: > image: yugabytedb/yugabyte:latest > hostname: yb-tserver-n1 > container_name: yb-tserver-n1 > networks: > - dbinternal > - dbnet > volumes: > - yb-tserver-data-1:/mnt/tserver > command: [ "/home/yugabyte/bin/yb-tserver", > "--fs_data_dirs=/mnt/tserver", > "--start_pgsql_proxy", > "--rpc_bind_addresses=yb-tserver-n1:9100", > "--tserver_master_addrs=yb-master-n1:7100" > ] > ports: > - "9042:9042" > - "5433:5433" > - "9000:9000" > environment: > SERVICE_5433_NAME: ysql > SERVICE_9042_NAME: ycql > SERVICE_6379_NAME: yedis > SERVICE_9000_NAME: yb-tserver > depends_on: > - yb-master > > yb-client: > image: yugabytedb/yb-sample-apps:latest > container_name: yb-client-n1 > networks: > - dbnet > command: ["--workload", "SqlInserts", "--nodes", "yb-tserver-n1:5433"] > depends_on: > - yb-tserver > > ``` > **Result** > > ```auto > $ docker-compose up > Removing yb-client-n1 ... done > Removing yb-tserver-n1 ... done > Removing yb-master-n1 ... done > Removing network yugabyte_dbinternal > Removing network yugabyte_dbnet > Removing volume yugabyte_yb-master-data-1 > Removing volume yugabyte_yb-tserver-data-1 > Creating network "yugabyte_dbinternal" with the default driver > Creating network "yugabyte_dbnet" with the default driver > Creating volume "yugabyte_yb-master-data-1" with default driver > Creating volume "yugabyte_yb-tserver-data-1" with default driver > Creating yb-master-n1 ... done > Creating yb-tserver-n1 ... done > Creating yb-client-n1 ... done > Attaching to yb-master-n1, yb-tserver-n1, yb-client-n1 > yb-client-n1 | 0 [main] INFO com.yugabyte.sample.Main - Starting sample app... > yb-client-n1 | 69 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Using a randomly generated UUID : 9ee0beee-7c95-4bfc-b983-c17a31320a9c > yb-client-n1 | 77 [main] INFO com.yugabyte.sample.common.CmdLineOpts - App: SqlInserts > yb-client-n1 | 77 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Run time (seconds): -1 > yb-client-n1 | 77 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Adding node: yb-tserver-n1:5433 > yb-client-n1 | 78 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Num reader threads: 2, num writer threads: 2 > yb-client-n1 | 78 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Num unique keys to insert: 2000000 > yb-client-n1 | 78 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Num keys to update: 0 > yb-client-n1 | 78 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Num keys to read: 1500000 > yb-client-n1 | 78 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Value size: 0 > yb-client-n1 | 78 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Restrict values to ASCII strings: false > yb-client-n1 | 78 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Perform sanity check at end of app run: false > yb-client-n1 | 78 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Table TTL (secs): -1 > yb-client-n1 | 78 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Local reads: false > yb-client-n1 | 79 [main] INFO com.yugabyte.sample.common.CmdLineOpts - Read only load: false > yb-client-n1 | 157 [main] INFO com.yugabyte.sample.apps.AppBase - Going to retrieve connection again: Connection to yb-tserver-n1:5433 refused.
