Installation
Installing Percona Kubernetes Operator for Percona Server for MongoDB
New Features¶
-
K8SPSMDB-273: Add support for
mongos
service to expose a single shard of a MongoDB cluster through one entry point instead of provisioning a load-balancer per replica set node. In the following release, we will add support for multiple shards. -
K8SPSMDB-282: Official support for Percona Monitoring and Management (PMM) v.2
Note
Monitoring with PMM v.1 configured according to the unofficial instruction will not work after the upgrade. Please switch to PMM v.2.
Improvements¶
-
K8SPSMDB-258: Add support for Percona Server for MongoDB version 4.4
-
K8SPSMDB-319: Show Endpoint in the
kubectl get psmdb
command output to connect to a MongoDB cluster easily -
K8SPSMDB-257: Store the Operator version as a
crVersion
field in thedeploy/cr.yaml
configuration file -
K8SPSMDB-266: Use plain-text passwords instead of base64-encoded ones when creating System Users secrets for simplicity
Bugs Fixed¶
-
K8SPSMDB-268: Fix a bug affecting the support of TLS certificates issued by cert-manager , due to which proper rights were not set for the role-based access control, and Kubernetes versions newer than 1.15 required other certificate issuing sources
-
K8SPSMDB-261: Fix a bug due to which cluster pause/resume functionality didn’t work in previous releases
-
K8SPSMDB-292: Fix a bug due to which not all clusters managed by the Operator were upgraded by the automatic update
Removal¶
- The MMAPv1 storage engine is no longer supported for all MongoDB versions starting from this version of the Operator. MMAPv1 was already deprecated by MongoDB for a long time. WiredTiger is the default storage engine since MongoDB 3.2, and MMAPv1 was completely removed in MongoDB 4.2.
Note
Upgrade of the Operator from 1.5.0 to 1.6.0 will fail if MMAPv1 is used, but MongoDB cluster will continue to run. It is recommended to migrate your clusters to WiredTiger engine before the upgrade.
