Troubleshooting

Calico related problems

If you use standalone bare metal servers, or if you experience issues with a Calico bird daemon and networking for a Kubernetes cluster VMs, ensure that netfilter for bridge interfaces is disabled for your host node(s):

echo 0 > /proc/sys/net/bridge/bridge-nf-call-iptables

Otherwise, bird daemon inside Calico won't function correctly because of libvirt and NAT networks. More details can be found in this bug.

Then reporting issues, please also make sure to include details on the host OS type and its kernel version.

DNS resolve issues

See a known configuration issue. The workaround is as simple as described in the bug: always define custom intranet DNS resolvers in the upstream_dns_servers var listed in the first place, followed by public internet resolvers, if any.

Network check

While a net check is a part of deployment process, you can run it manually from the admin node as well:

export ws=~/workspace/
/usr/bin/ansible-playbook -e ansible_ssh_pass=vagrant -u vagrant -b \
--become-user=root -i ~/${ws}inventory/inventory.cfg \
-e @${ws}kargo/inventory/group_vars/all.yml \
-e @${ws}inventory/kargo_default_common.yaml \
-e @${ws}inventory/kargo_default_ubuntu.yaml \
-e @${ws}inventory/custom.yaml \
${ws}utils/kargo/postinstall.yml -v --tags postinstall
