  9. kubeadmin and developer credentials are now shown on screen.

Remote Access

  1. Install HAProxy sudo dnf install haproxy

  2. Allow traffic through firewall 

    sudo systemctl enable --now firewalld
sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --add-service=https --permanent
sudo firewall-cmd --add-service=kube-apiserver --permanent
sudo firewall-cmd --reload

  3. Allow API port 6443 through SELinux sudo semanage port -a -t http_port_t -p tcp 6443

  4. Backup HAProxy configuration sudo cp /etc/haproxy.cfg /etc/haproxy.cfg.backup

  5. Configure HAProxy

  6. Get the IP of the CRC container 

    crc ip
    /etc/haproxy.cfg
    global
   log /dev/log local0

defaults
   balance roundrobin
   log global
   maxconn 100
   mode tcp
   timeout connect 5s
   timeout client 500s
   timeout server 500s

listen apps
   bind 0.0.0.0:80
   server crcvm $CRC_IP:80 check

listen apps_ssl
   bind 0.0.0.0:443
   server crcvm $CRC_IP:443 check

listen api
   bind 0.0.0.0:6443
   server crcvm $CRC_IP:6443 check

  7. Start HAProxy service 

    sudo systemctl enable haproxy --now
sudo systemctl start haproxy

  8. Change DNS entry to point to the IP address of the VM.
