MCK 1.6.0 Release Notes

New Features

• MongoDBCommunity: Added support to configure custom cluster domain via newly introduced spec.clusterDomain resource field. If spec.clusterDomain is not set, environment variable CLUSTER_DOMAIN is used as cluster domain. If the environment variable CLUSTER_DOMAIN is also not set, operator falls back to cluster.local as default cluster domain.
• Helm Chart: Introduced two new helm fields operator.podSecurityContext and operator.securityContext that can be used to configure securityContext for Operator deployment through Helm Chart.

Bug Fixes

• Fixed parsing of the customEnvVars Helm value when values contain = characters.
• ReplicaSet: Blocked disabling TLS and changing member count simultaneously. These operations must now be applied separately to prevent configuration inconsistencies.

Other Changes

• kubectl-mongodb plugin: cosign, the signing tool that is used to sign kubectl-mongodb plugin binaries, has been updated to version 3.0.2. With this change, released binaries will be bundled with .bundle files containing both signature and certificate information. For more information on how to verify signatures using new cosign version please refer to -> https://github.com/sigstore/cosign/blob/v3.0.2/doc/cosign_verify-blob.md
