TiDB Operator v1.0.6 Release Notes

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
  ...

Monitor

There is no action required if you are upgrading from v1.0.4.

Scheduled Backup

  • Fix the issue that backup failed when clusterName is too long (#1229)

TiDB Binlog

  • It is recommended that TiDB and Pump be deployed on the same node through the affinity feature and Pump be dispersed on different nodes through the anti-affinity feature. At most only one Pump instance is allowed on each node. We added a guide to the chart. (#1251)

TiDB Operator v1.0.4 Release Notes

v1.0.4 What's New

Action Required

There is no action required if you are upgrading from v1.0.3.

Highlights

#1202 introduced HostNetwork support, which offers better performance compared to the Pod network. Check out our benchmark report for details.

Note:

Due to this issue of Kubernetes, the Kubernetes cluster must be one of the following versions to enable HostNetwork of the TiDB cluster:

  • v1.13.11 or later
  • v1.14.7 or later
  • v1.15.4 or later
  • any version since v1.16.0

#1175 added the podSecurityContext support for TiDB cluster Pods. We recommend setting the namespaced kernel parameters for TiDB cluster Pods according to our Environment Recommendation.

New Helm chart tidb-lightning brings TiDB Lightning support for TiDB in Kubernetes. Check out the document for detailed user guide.

Another new Helm chart tidb-drainer brings multiple drainers support for TiDB Binlog in Kubernetes. Check out the document for detailed user guide.

Improvements

  • Support HostNetwork (#1202)
  • Support configuring sysctls for Pods and enable net.* (#1175)
  • Add tidb-lightning support (#1161)
  • Add new helm chart tidb-drainer to support multiple drainers (#1160)

Detailed Bug Fixes and Changes

  • Add e2e scripts and simplify the e2e Jenkins file (#1174)
  • Fix the pump/drainer data directory to avoid data loss caused by bad configuration (#1183)
  • Add init sql case to e2e (#1199)
  • Keep the instance label of drainer same with the TiDB cluster in favor of monitoring (#1170)
  • Set podSecuriyContext to nil by default in favor of backward compatibility (#1184)

Additional Notes for Users of v1.1.0.alpha branch

For historical reasons, v1.1.0.alpha is a hot-fix branch and got this name by mistake. All fixes in that branch are cherry-picked to v1.0.4 and the v1.1.0.alpha branch will be discarded to keep things clear.

We strongly recommend you to upgrade to v1.0.4 if you are using any version under v1.1.0.alpha.

v1.0.4 introduces the following fixes comparing to v1.1.0.alpha.3:

  • Support HostNetwork (#1202)
  • Add the permit host option for tidb-initializer job (#779)
  • Fix drainer misconfiguration in tidb-cluster chart (#945)
  • Set the default externalTrafficPolicy to be Local for TiDB services (#960)
  • Fix tidb-operator crash when users modify sts upgrade strategy improperly (#969)
  • Add the maxFailoverCount limit to TiKV (#976)
  • Fix values file customization for tidb-operator on aliyun (#983)
  • Do not limit failover count when maxFailoverCount = 0 (#978)
  • Suspend the ReplaceUnhealthy process for TiKV auto-scaling-group on AWS (#1027)
  • Fix the issue that the create_tidb_cluster_release variable does not work (#1066))
  • Add v1 to statefulset apiVersions (#1056)
  • Add timezone support (#1126)

TiDB Operator v1.0.3 Release Notes

v1.0.3 What's New

Action Required

ACTION REQUIRED: This release upgrades default TiDB version to v3.0.5 which fixed a serious bug in TiDB. So if you are using TiDB v3.0.4 or prior versions, you must upgrade to v3.0.5.

ACTION REQUIRED: This release adds the timezone support for all charts.

For existing TiDB clusters. If the timezone in tidb-cluster/values.yaml has been customized to other timezones instead of the default UTC, then upgrading tidb-operator will trigger a rolling update for the related pods.

The related pods include pump, drainer, discovery, monitor, scheduled backup, tidb-initializer, and tikv-importer.

The time zone for all images maintained by tidb-operator should be UTC. If you use your own images, you need to make sure that the corresponding time zones are UTC.

Improvements

  • Add the timezone support for all containers of the TiDB cluster
  • Support configuring resource requests and limits for all containers of the TiDB cluster

Detailed Bug Fixes and Changes

  • Upgrade default TiDB version to v3.0.5 (#1132)
  • Add the timezone support for all containers of the TiDB cluster (#1122)
  • Support configuring resource requests and limits for all containers of the TiDB cluster (#853)

TiDB Operator v1.0.2 Release Notes

v1.0.2 What's New

Action Required

The AWS Terraform script uses auto-scaling-group for all components (PD/TiKV/TiDB/monitor). When an ec2 instance fails the health check, the instance will be replaced. This is helpful for those applications that are stateless or use EBS volumes to store data.

But a TiKV Pod uses instance store to store its data. When an instance is replaced, all the data on its store will be lost. TiKV has to resync all data to the newly added instance. Though TiDB is a distributed database and can work when a node fails, resyncing data can cost much if the dataset is large. Besides, the ec2 instance may be recovered to a healthy state by rebooting.

So we disabled the auto-scaling-group's replacing behavior in v1.0.2.

Auto-scaling-group scaling process can also be suspended according to its documentation if you are using v1.0.1 or prior versions.

Improvements

  • Suspend ReplaceUnhealthy process for AWS TiKV auto-scaling-group
  • Add a new VM manager qm in stability test
  • Add tikv.maxFailoverCount limit to TiKV
  • Set the default externalTrafficPolicy to be Local for TiDB service in AWS/GCP/Aliyun
  • Add provider and module versions for AWS

Bug fixes

  • Fix the issue that tkctl version does not work when the release name is un-wanted
  • Migrate statefulsets apiVersion to app/v1 which fixes compatibility with Kubernetes 1.16 and above versions
  • Fix the issue that the create_tidb_cluster_release variable in AWS Terraform script does not work
  • Fix compatibility issues by adding v1beta1 to statefulset apiVersions
  • Fix the issue that TiDB Loadbalancer is empty in Terraform output
  • Fix a compatibility issue of TiKV maxFailoverCount
  • Fix Terraform providers version constraint issues for GCP and Aliyun
  • Fix values file customization for tidb-operator on Aliyun
  • Fix tidb-operator crash when users modify statefulset upgrade strategy improperly
  • Fix drainer misconfiguration

Detailed Bug Fixes and Changes

  • Fix the issue that tkctl version does not work when the release name is un-wanted (#1065)
  • Fix the issue that the create_tidb_cluster_release variable in AWS terraform script does not work (#1062)

  • Fix drainer misconfiguration (#939)
  • Add provider and module versions for AWS (#926)

TiDB Operator v1.0.1 Release Notes

v1.0.1 What's New

Action Required

  • ACTION REQUIRED: We fixed a serious bug (#878) that could cause all PD and TiKV pods to be accidentally deleted when kube-apiserver fails. This would cause TiDB service outage. So if you are using v1.0.0 or prior versions, you must upgrade to v1.0.1.
  • ACTION REQUIRED: The backup tool image pingcap/tidb-cloud-backup uses a forked version of Mydumper. The current version pingcap/tidb-cloud-backup:20190610 contains a serious bug that could result in a missing column in the exported data. This is fixed in #29. And the default image used now contains this fixed version. So if you are using the old version image for backup, you must upgrade to use pingcap/tidb-cloud-backup:201908028 and do a new full backup to avoid potential data inconsistency.

Improvements

  • Modularize GCP Terraform
  • Add a script to remove orphaned k8s disks
  • Support binlog.pump.config, binlog.drainer.config configurations for Pump and Drainer
  • Set the resource limit for the tidb-backup job
  • Add affinity to Pump and Drainer configurations
  • Upgrade local-volume-provisioner to v2.3.2
  • Reduce e2e run time from 60m to 20m

  • Support specifying the permit host in the values.tidb.permitHost chart
  • Add the zone label and reserved resources arguments to kubelet
