Metabase kubernetes4/15/2023 ![]() a security group for the virtual instance.a virtual instance to act as a bastion to access RDB from outside.The overall architecture that we will implement during this article is as follows: Download, install, and configure the Scaleway CLI.Pods have access to RDB database using Username/Password.Įach architecture has its own advantages and disadvantages but all apply project isolation best practices for securing sensitive data in RDB. In this architecture, our RDB instance is isolated on its own project accessible through public IP address to only Kapsule cluster that requires access to it. Public Gateway is not available yet for Kubernetes Kapsule and RDB instance, see featurer request, so you need to whitelist all the Kubernetes nodes IPs.ĭirect communication in separate projects Pods have access to RDB database using Username/Password. In this architecture, our RDB instance is isolated on Scaleway network and accessible through public IP address to only Kapsule cluster that requires access to it. Let's discover the possible architectures that could be used to implement each scenario.ĭirect communication with public IP and authorized networks A Kapsule cluster and a RDB instance in a different project.A Kapsule cluster and a RDB instance in the same project.The scenarios that concern us are the first two: A feature request is opened and it's ongoing. The private network scenario is actually not possible. A virtual instance in a different projectĪ client application through the internet.RDB service supports the following scenarios for accessing the RDB instance: Which architecture could be the most efficient, maintainable and scalable? Which network topology to choose? How to authenticate and authorize the connection to the RDB instance? Can I publicly expose a RDB instance? Important points should be taken into account in setting up this connectivity. In cloud computing, in the case of Scaleway Elements, the equivalent is connecting a container in a Scaleway Kubernetes Kapsule cluster to a Scaleway Relational Database instance (RDB). 13:23:13,054 INFO metabase.It is very easy today to establish a connection between a container in Kubernetes and a relational database server, just create a SQL user and open a TCP connection. 13:22:48,068 INFO db.setup :: Database Migrations Current. 13:22:42,980 INFO db.liquibase :: Migration lock is cleared.

Upgrade the VPC CNI to the latest version.It will be assigned to the metabase service account. Create a security group that allows inbound traffic to RDS.Enable Pod Security Group by adding the managed policy AmazonEKSVPCResourceController on Amazon EKS cluster.It will be added to the metabase service account. Create an IAM role to connect to the RDS instance.In this part, we'll put them all together and deploy the metabase to Kubernetes. In the previous part we created our RDS instance.
