Full Changelog: v0.2.0...v0.2.1

v0.2.0

First release of mssql-operator, a Kubernetes operator for SQL Server on Linux.

It runs standalone instances and Always On availability groups, and acts as their cluster manager: it promotes a secondary only once the old primary can no longer write, and with durability: Quorum an automatic failover never loses an acknowledged commit. It supports SQL Server 2019, 2022 and 2025.

Custom resources (mssql-operator.evariops.com/v1alpha1, the API can still change):

• SqlInstance: a standalone SQL Server
• SqlAvailabilityGroup: an availability group, its listeners, failovers and rolling updates
• SqlDatabase: a user database, created or adopted, with its options and files
• SqlAvailabilityGroupDatabase: a database joined to an availability group, with seeding, re-seed and log backups
• SqlUser: a login, its database users and permissions
• SqlConfiguration: sp_configure, trace flags, tempdb and Database Mail
• SqlAgentJob: a SQL Server Agent job
• SqlStoredProcedure: stored procedures, inline or from a GitHub repository
• SqlTdeCertificate: transparent data encryption and certificate rotation
• SqlControlRecord: the safety state of an availability group or an instance, written by the operator only
