Environment Variables

Generate secrets​

K3s token:

pulumi --cwd $PULUMI_CWD config set --secret k3s:token $(openssl rand -base64 32)

Cluster domain:

pulumi --cwd $PULUMI_CWD config set --secret cluster:domain {REPLACE_WITH_YOUR_DOMAIN}
important

Cluster domain is the domain you will use to access services like Harbor, Grafana, etc. In the later steps we will create wildcard DNS records pointing to the load balancer IP.

For example, if your cluster domain is nursery.example.com, you will create DNS record for:

  • *.nursery.example.com -> Load Balancer IP

Export necessary environment variables​

You can copy and paste the following commands to set the environment variables required for the K3s installation.

export K3S_TOKEN=$(pulumi --cwd $PULUMI_CWD config get k3s:token); \
export CLUSTER_DOMAIN=$(pulumi --cwd $PULUMI_CWD config get cluster:domain); \
export INSTALL_K3S_VERSION="v1.32.3+k3s1"; \
export K8S_URL=k8s.${CLUSTER_DOMAIN};

k3s version can be checked at: https://github.com/k3s-io/k3s/releases/tag/v1.32.3+k3s1
