Stellar on Kubernetes: initialization Google Cloud

For Stellar nodes on Google Cloud we use automatically provisioned SSDs.

Create a file storage-ssd.yaml with the following content:

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
 name: ssd

Stellar on Kubernetes: initialization IBM Cloud

(Provided by @todkap)

Stellar Core and Horizon leverage Kubernetes dynamic provisioning for their storage classes (https://kubernetes.io/blog/2017/03/dynamic-provisioning-and-storage-classes-kubernetes/). The default storage class for IBM Cloud is file-based and has known limitations with regards to docker images running as non-root. To avoid this limitation, we can change the default storage class to block storage (requires the installation of an IBM block storage helm chart from the IBM Cloud Helm Repository) and a patch to the default storage classes we want to disable and enable.

# Get the IBM block storage classes from IKS helm repo
$ helm repo add iks-charts https://icr.io/helm/iks-charts
$ helm repo update

Compile icinga2 and icingaweb2 on Ubuntu 14.04 trusty

The ppa does not build packages for ARM (e.g. ODROID U3), so let's compile them.

Configure pbuilder

Make sure that /etc/pbuilderrc contains the line

echo 'COMPONENTS="main universe multiverse restricted"' | sudo tee -a /etc/pbuilderrc

Create trusty build env

Build icinga2 and icinga-web Debian/Ubuntu packages for non-{i386,amd64} architectures

Why?

The icinga PPA only provides packages for i386 and amd64. If you're running an ARM-powered device such as the Raspberry Pi or the ODROID U3 (which I use), you have to build the packages yourself. However, compiling the packages is very easy thanks to Debian's excellent build tools and the work of the icinga package maintainer. This howto uses pbuilder which builds in a clean chroot so your original system is not polluted with build packages.
