TiDB Operator 1.0.6 Release Notes

Release date: December 27, 2019

TiDB Operator version: 1.0.6

v1.0.6 What's New

Action required: Users should migrate the configs in values.yaml of previous chart releases to the new values.yaml of the new chart. Otherwise, the monitor pods might fail when you upgrade the monitor with the new chart.

For example, configs in the old values.yaml file:

monitor:
  ...
  initializer:
    image: pingcap/tidb-monitor-initializer:v3.0.5
    imagePullPolicy: IfNotPresent
  ...

After migration, configs in the new values.yaml file should be as follows:

monitor:
  ...
  initializer:
    image: pingcap/tidb-monitor-initializer:v3.0.5
    imagePullPolicy: Always
    config:
      K8S_PROMETHEUS_URL: http://prometheus-k8s.monitoring.svc:9090
  ...
