Ysqlsh: FATAL: role "yugabyte" does not exist

hhferreira · September 24, 2019, 9:18am

While going through the tutorial, I got stuck while trying to initialize ysqlsh to create demo tables and data.

Using Windows 10 with docker containers. Error is:

PS YugaByteDB> docker exec -it yb-tserver-n1 /home/yugabyte/bin/ysqlsh -h yb-tserver-n1  --echo-queries
ysqlsh: FATAL:  role "yugabyte" does not exist

Can you please help? I’m using docker-compose to start the containers with the template provided in the documentation:

version: '2'

services:
  yb-master:
      image: yugabytedb/yugabyte:latest
      container_name: yb-master-n1
      command: [ "/home/yugabyte/bin/yb-master", 
                "--fs_data_dirs=/mnt/disk0,/mnt/disk1", 
                "--master_addresses=yb-master-n1:7100", 
                "--replication_factor=1"]
      ports:
      - "7000:7000"
      environment:
        SERVICE_7000_NAME: yb-master

  yb-tserver:
      image: yugabytedb/yugabyte:latest
      container_name: yb-tserver-n1
      command: [ "/home/yugabyte/bin/yb-tserver", 
                "--fs_data_dirs=/mnt/disk0,/mnt/disk1",
                "--start_pgsql_proxy", 
                "--tserver_master_addrs=yb-master-n1:7100"]
      ports:
      - "9042:9042"
      - "6379:6379"
      - "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

Please advise.
Thanks.

Hi hhferreira
Can you try this ?

PS YugaByteDB> docker exec -it yb-tserver-n1 /home/yugabyte/bin/ysqlsh -U postgres -h yb-tserver-n1  --echo-queries```

Unfortunately, did not help as can be seen below:

Please advise.

Can you tell me which tutorial you’re using ?

hhferreira · September 26, 2019, 4:31pm

Sure, following URL used to launch docker: Deploy | YugabyteDB Docs

… and this one to create tables and sample data: YugabyteDB Quick start for macOS | YugabyteDB Docs

Any further hints?

Thanks in advance.

Hi @hhferreira,

It looks like YSQL didn’t end up getting initialized on your cluster. Can you please use this updated docker-compose.yaml?

version: '2'

      - yb-master

The main change is passing enable_ysql=true flag to yb-master process.

Steps to get it working will then be:

docker-compose down : This will remove existing cluster
docker-compose up -d : Create cluster using the new yaml
docker exec -it yb-tserver-n1 /home/yugabyte/bin/ysqlsh -h yb-tserver-n1 --echo-queries : Connect to YSQL shell.

Let me know if this works.

hhferreira · September 27, 2019, 8:26am

Still not working

PS YugaByteDB> docker exec -it yb-tserver-n1 /home/yugabyte/bin/ysqlsh -h yb-tserver-n1 --echo-queries
ysqlsh: FATAL: Not found: Error loading table with oid 1260 in database with oid 1: The object does not exist: table_id: “000000010000300080000000000004ec”

Could it be an error in the latest docker image?

dorian_yugabyte · September 27, 2019, 1:17pm

Just tried with the latest docker image in a clean environment using the config from neha.
Can you repeat again doing steps:

docker-compose stop
docker-compose rm
docker-compose up -d
docker exec -it yb-tserver-n1 /home/yugabyte/bin/ysqlsh -h yb-tserver-n1 --echo-queries

Those commands run serially should work.
Taken from: Deploy | YugabyteDB Docs

Can you also run ps -ef and confirm that yb-master was started with —enable_ysql?

Can you also print the version that you’re using by doing select version(); in YSQL ?

hhferreira · September 27, 2019, 2:30pm

Thanks! Working now, I had a weird character in my docker-compose.yaml file and the latest change to include the —enable_ysql was not being run. Nevertheless, i suggest you to update the documentation about the docker-compose.yaml definition to include this flag.

Best Regards,
Hélder Hugo Ferreira

neha · September 27, 2019, 4:55pm

Good to see that it’s working now!
We’ve updated documentation as well, thanks for the feedback.
