[install] docker-compose.ha.yaml 3-node ClickHouse cluster fails due to missing unique macros.replica

[codesenju]

Bug description

When deploying SigNoz with a 3-node ClickHouse HA cluster using docker-compose.ha.yaml, the schema migrator fails with replica conflicts. All three ClickHouse nodes attempt to use the same default replica name, causing ZooKeeper to reject subsequent replica registrations.

Error observed:

Replica /clickhouse/tables/.../replicas/example01-01-1 already exists. (REPLICA_ALREADY_EXISTS)

Expected behavior

Each ClickHouse node should have a unique replica name, allowing successful creation of ReplicatedMergeTree tables across the cluster without conflicts.

How to reproduce

1. Clone SigNoz repository: git clone https://github.com/SigNoz/signoz.git
2. Navigate to deploy/docker: cd signoz/deploy/docker
3. Use HA compose: cp docker-compose.ha.yaml docker-compose.yaml
4. Deploy: docker compose up -d
5. Observe migrator logs: docker logs signoz-telemetrystore-migrator

Expected: Migrations complete successfully
Actual: Migrator fails with REPLICA_ALREADY_EXISTS error

Version information

• SigNoz version: v0.113.0 (latest main)
• Your OS and version: Ubuntu 22.04
• Your CPU Architecture: x86_64 (Intel/AMD)

Additional context

The fix requires adding unique macros.replica configuration for each ClickHouse node:

• macros-1.xml → <replica>replica_1</replica>
• macros-2.xml → <replica>replica_2</replica>
• macros-3.xml → <replica>replica_3</replica>
