Elixier is a data platform stack on Kubernetes.

• Some knowledge on Kubernetes, kubectl, helm and k3s

  • https://docs.k3s.io/quick-start

  • https://docs.k3s.io/cluster-access

  • https://helm.sh/docs/intro/quickstart/

• You need at least 100GB free space, preferably SSD

• At least 16 vCore with 32GB RAM is recommended, or you might face issue where kubernetes unable to allocate resources for the services, or services crashing. 8vCore with 16GB RAM can still work, but do not enable elixier-security, auto scaling and high availability.

1. Prepare the OS:

   Install OS dependencies. Assuming you are on CentOS/RHEL:

   dnf install iscsi-initiator-utils nfs-utils tar git -y

   disable firewalld as it will interfere with container networking:

   systemctl stop firewalld
   systemctl disable firewalld 

   set vm.max_map_count for opensearch:

   echo vm.max_map_count=262144 > /etc/sysctl.d/00-vm-max-map-count.conf
   sysctl --system

2. Install K3S:

   curl -sfL https://get.k3s.io | sh -

3. Install helm:

   curl -sfL https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | sh -

4. Clone:

   git clone https://github.com/elixierco/elixier elixier

5. Install Elixier. Please replace ${IP_ADDRESS} with the main IP address of the server

   export KUBECONFIG=/etc/rancher/k3s/k3s.yaml
   helm install --set storageAccessMode=ReadWriteOnce \
                --set ingress.domain=${IP_ADDRESS}.sslip.io \
                elixier \
                elixier/helm/elixier

   To check for deployment status, run watch kubectl get pods.

   NOTE: If you are using sslip.io, do make sure that you manage /etc/resolv.conf manually instead of using NetworkManager. NM adds ${IP_ADDRESS}.sslip.io in search paths in /etc/resolv.conf which may cause DNS resolution issues in kubernetes.
