Hopr Kubernetes operator

A Kubernetes operator built on top of kube-rs project to handle hoprd nodes

Prerequisites

Bear in mind that in order for the wallet to work correctly, the wallet has be compliant with the following requirements:

• Hold a Developer NFT for monte_rosa which has been staked for Season 6 or later
• Have enough funds in mHOPR
• Have enough funds in xDAI

Usage

This operator provides two CRD:

• Hoprd: This resource manage a single hoprd node. See the specifications for details about what can be configured on an specific hoprd node.
• ClusterHoprd: This resource manage a cluster of related hoprd nodes. See the specifications for details about what can be configured on a cluster of nodes.

Note: Keep in mind that the network attributes of a node cannot be modified.

Development

1. Use kubectl apply -f hoprds.hoprnet.org.yaml to create the CustomResourceDefinition inside Kubernetes.
2. Build the project with cargo build. If the build fails, make sure libssl-dev is available.
3. Run the operator using cargo run. It will run outside of the Kubernetes cluster and connect to the Kubernetes REST API using the account inside the KUBECONFIG automatically.

Finally, a custom Hoprd resource can be created with kubectl apply -f hoprd-node-1.yaml. A new deployment with Hoprd node will be created.

CRD

Include a given CRD into the Rust code:

kopium servicemonitors.monitoring.coreos.com -A > src/service_monitor.rs

Container

Build the hoprd-operator container using in the repo root:

docker build -t europe-west3-docker.pkg.dev/hoprassociation/docker-images/hoprd-operator:latest .
