CHANGELOG.md

unreleased

v0.1.56 (beta) - August 26, 2024

• Update dependencies: (@d-honeybadger)
  • k8s.io packages v0.31.0
  • sigs.k8s.io/controller-runtime v0.19.0
  • github.com/prometheus/client_golang v1.20.2
• Update go to 1.23 (@d-honeybadger)

v0.1.55 (beta) - July 29, 2024

• When using the LoadBalancer service.beta.kubernetes.io/do-loadbalancer-type=REGIONAL_NETWORK (under closed beta), firewall rules are added to open up the underlying health check port and all the defined (port, protocols) defined on the service. This is to permit traffic to arrive directly on the underlying worker nodes.

v0.1.54 (beta) - June 12, 2024

• Fixes an issue with load balancer health checks when the LB is using PROXY protocol. The new health check implementation (introduced in v0.1.51), now probes either kube proxy (Cluster) or the health check node port (Local). If the LB enables PROXY protocol, this alters the health check behavior to also use PROXY protocol. Since these Kubernetes components don't support PROXY protocol, this caused worker nodes to be marked as unhealthy. Support was added to the load balancer health check to optionally enable/disable PROXY protocol. When using the default health check implementation the health check will disable PROXY protocol. If the service.beta.kubernetes.io/do-loadbalancer-override-health-check is provided, then the health check will default to the setting on the LB.

v0.1.53 (beta) - June 7, 2024

• Adding support for internal load balancers (NOTE: this is a closed beta feature, contact DigitalOcean support to review its public availability). This is enabled by setting a new annotation service.beta.kubernetes.io/do-loadbalancer-network to INTERNAL.

v0.1.52 (beta) - June 4, 2024

• Adding support for specifiying loadBalancerSourceRanges in the service spec. Source ranges take precedence over annotation based allow rules (service.beta.kubernetes.io/do-loadbalancer-allow-rules).

v0.1.51 (beta) - May 28, 2024

• Adjusts load balancer health check behaviour to probe Kubernetes components correctly, ensuring that LB traffic stops in time in case of unavailability and pending node replacements. The concrete health check configuration depends on the specified external traffic policy. See the extended documentation for details.
• Adding new annotation service.beta.kubernetes.io/do-loadbalancer-certificate-name to configure which TLS certificate to use for HTTPs forwarding rules. This can be used instead of service.beta.kubernetes.io/do-loadbalancer-certificate-id which needs to be manually updated when using Let's Encrypt certificates. This is due to the certificate ID updating each time the certificate is rotated. If both annotations are provided, then service.beta.kubernetes.io/do-loadbalancer-certificate-id takes precedence.
