Hi! Anyone can do a successful deployment of a Neo4j 4.0 image on Kubernetes? I have a lot of problems! ---

Hi Mariano - we're still in the process of upgrading our helm charts internally for 4.0. In particular a key challenge with the change to 4.0 that you may be encountering is the SSL subsystem; previously Neo4j generated its own self-signed certificate. Configuration that enabled https by default used that, and there were some changes in 4.0 that make startup require extra steps to generate that self-signed certificate. You can certainly post your challenges here and I'll follow up later if I can - but for now also be aware that updated helm charts for GKE are already in the works. ---

Perfect! I deploy a Neo4j single instance and wait for de GA of the Cluster of 4.0 ---

Hi David, any news on this? Will the helm chart be the only deployment option or do you have/plan other ways (kustomize, operator)? ---

Sorry - no update. The status is the same as above right now. ---

I'm going to left this here... [https://drive.google.com/open?id=1SZeSOI\_-Jw897tgWeL3QxUxKW7mkXMZs](https://drive.google.com/open?id=1SZeSOI_-Jw897tgWeL3QxUxKW7mkXMZs) Has a few changes to work in AKS. And... maybe you can adjust the memory and CPU ---

UPDATE: a PR is pending to get 4.0 support for Neo4j into the stable helm chart in the public helm repo. > > > \#### What this PR does / why we need it: > > \- Neo4j \[released a major new versio…n (4.0)\](https://neo4j.com/press-releases/announcing-neo4j-4-0/) which has a bunch of substantial new features: multi-database, fine-grained security, fabric queries, and others. This version has some substantial differences/incompatibilities from the old series (3.5) that the old chart is based on > \- Fixes #21439 by enabling custom configuration to be passed to all pods with a simple configmap name. > \- Adds simple readiness and liveness probes, for indications of when cluster formation has been successful. > \- Adds APOC installed by default. Most users want APOC in, so this has been done by default with a toggle (useAPOC) which can be trivially set to false if APOC is not wanted. This saves users from setting up initContainers themselves each time. > \- Adds a service for contacting read replicas. This is useful when read-only analytic workloads need to be pointed to an auto-scaling subset of cluster members. > \- Adds a lot of useful Links, References, and additional documentation for people who use the chart with information on techniques like backup & recovery for Neo4j in Kubernetes > > So this PR enables a major new set of features with Neo4j 4.0. As such, and because the underlying product versions were revised by a major version, the chart version is going up a major version as well. > > \#### Special notes for your reviewer: > > \#### Checklist > \[Place an '\[x\]' (no spaces) in all applicable fields.
