Hey! How's it going? I'm having some issues self hosting SigNoz. I'm running the recommended clickhouse server (the one specified in the

docker-compose

from the github) with zookeeper. Now i'm trying to deploy the schema migrators, starting with the sync one first. I deployed the image from dockerhub and added an env var to point to my clickhouse dsn TCP port. This is my start command (this is the only place I use the env var).

/bin/sh -c "/signoz-schema-migrator sync --dsn=http://${CLICKHOUSE_DSN} --up= --replication=false"

And I get a weird error, first it says it can't connect to the host but it tries to run the migrations? clickhouse server instance logs the connection

Error: failed to bootstrap migrations: failed to create schema_migrations_v2 table

Super weird, what exactly is failling to connect since it seems like it tries to run migrations on the clickhouse server? Why isn't it creating the

schema_migrations_v2

table? Clickhouse instance works fine, i've tested it. Any insight on this is greatly appreciated.

You are running a single shard for clickhouse ?
