- Log rotation improvements and dedicated database user for it
- Path for major version upgrades, from 6 to 8
- Switching to a file based config management for predictability
- Tuning of ulimits and sysctl parameters
- Multiple bug fixes and stabilisation
- All charms keep full feature parity cross-substrates, get tested and released at once - ensuring full compatibility on every new releases.
Inside the charms:
- Percona Server for MongoDB: 6.0.24-19
- Percona Backup MongoDB (PBM): 2.9.1
- Percona MongoDB Exporter: 0.44.0
- MongoDB Shell: 2.5.5
Artifacts:
In addition to our charms, we also released to 6/stable other artifacts, namely:
| Artifact | Version | Sources (github) | License |
|---|---|---|---|
| Snap: Charmed MongoDB | 6.0.24-19 | charmed-mongodb-snap | Apache 2.0 |
| Rock: Charmed MongoDB | 6.0.24-19 | charmed-mongodb-rock | Apache 2.0 |
2. Charmed MongoDB 8 and the transition path from 6:
In addition to the above, we have released new candidate releases for all Charmed MongoDB 8 artifacts.
The supported base for Charmed MongoDB 8 will be: 24.04.
Please give us feedback on this candidate release.
Transition path:
In order to migrate from “Charmed MongoDB 6” to “Charmed-MongoDB 8”, it is imperative that the transition happens through the artifacts located in an intermediary track: 8/transition (which contains the mongodb 7 binaries).
The 8/transition track will remain in edge and should only be used for the transition from 6 to 8.
Note1: The supported base for the 8/transition track will be 24.04.
Note2: Do not move your current production workloads to this track until we announce the stable release.
The major version upgrades procedure are documented in the guide found here for VM charms and here for k8s deployments.
In short:
MongoDB 6/stable -> MongoDB 8/transition -> MongoDB 8/stable
Next work items for Charmed MongoDB 8 before hitting stable:
We will be working on preparing a stable release for it, in which we will:
- Move away from charm refresh v2 to v3
- Migrate from TLS v3 libs to TLS v4
- Deprecate
get-password / set-password / set-tls-private-keyactions in favour of a juju secrets based approach. - Separate storage volumes for data and logging
- Deprecate
auto-deleteconfig options
3. Deprecation notice:
