Helm is a package manager for Kubernetes. You can bundle Kubernetes resources together as charts that define all the necessary resources and dependencies of an application. You can then use the Helm CLI to install all the pods, services, and ingresses for an application in one simple command.
Just like Docker or NuGet, there’s a common public repository for Helm charts that the helm CLI uses by default. And just like Docker and NuGet, you can host your own Helm repository for your charts.
External DNS ExternalDNS’ current release is v0.5. This version allows you to keep selected zones (via --domain-filter) synchronized with Ingresses and Services of type=LoadBalancer in various cloud providers:

When you’r using the s3 plugin to store the Kops state inside a bucket, Kops stores the CA key and certificate in its S3 bucket.
aws s3 cp s3://$BUCKET/$CLUSTER/pki/private/ca/$KEY.key ca.key aws s3 cp s3://$BUCKET/$CLUSTER/pki/issued/ca/$CERT.crt ca.crt We will use this certificate to create some RBAC access.
BIND/named with PostgreSQL back end at CentOS 6.4 I’ve been trying to find a good documentation on setting up Bind with PostgreSQL as its back end. So far the information is sparse so I’ve decided to put this recipe together. There is much more than this but the idea is to give you a start.
1) First, make sure you have bind, bind-sdb, postgresql-server RPMs (and their dependencies) installed.
2) After having the RPMs in your system, you have to configure the iptables to allow DNS queries.
