@bogdando @mattymo guys have you seen this before ?

[mattymo]

I saw this before from someone else, but it was not clear why their env wasn't working. I'm inclined to think it's because you are deploying with a custom inventory dir (lacking group_vars/all.yml that is in Kargo git repo). There is this issue that discusses vars that don't have a default value https://github.com/kubernetes-incubator/kargo/issues/771. That could be the cause here. Make sure your ansible inventory has this group_vars/all.yml file

[ksingh7]

Thanks for you pointer @mattymo , but this is not due to all.yml as its present. After you pointed out i reverified my inventory file and found a diff that i don't have IP variable assigned to ansible hosts

Can you please tell me what the meaning of this comment in inventory file

Configure 'ip' variable to bind kubernetes services on a different ip than the default iface

On my AWS VMs i have just one interface with 1 private IP , like this

node1 ansible_ssh_host=10.100.0.101  ip=10.100.0.101
node2 ansible_ssh_host=10.100.0.102  ip=10.100.0.102

Will this ^ work ? ( comment says different IP than default iface )
How should i configure inventory file in this situation ?

Does kargo specifically need to have floating IP and additional private IP for each node ? Is it a requirement ?

Thank you for maintaining Kargo :)

[bogdando]

Kargo only supports systemd OS types starting from this checkpoint

[mootezbessifi]

Sorry but why closing this issue??
i have the same problem with specific inventory/hosts file like the following:
k8smaster ansible_ssh_host=192.168.0.7 ip=192.168.0.7

k8sminion1 ansible_ssh_host=192.168.0.8 ip=192.168.0.8

k8sminion2 ansible_ssh_host=192.168.0.9 ip=192.168.0.9

and running the next command:

ansible-playbook -i inventory/hosts -b --become-user=root cluster.yml

what should i do ?

PS: i am using Ansible v2.2.1.0 and a cluster of CentOS 7.3 VMs running on Openstack.

[mootezbessifi]

@ksingh7 any fix plz ?

[ejames12]

I've run into this issue also, it seems like whatever is rendering the kubelet.j2 jinja2 file doesn't like the {% set xxxxx %} yyyyy {% endset %} lines. {% set xxxxx = "yyyyy" %} seems OK.

Need to look into this further myself, will update if I find out exactly why it doesn't render set/endset.

upgraded to Jinja2 2.9.5 and it now works

I update ninja2 with the following command:

pip install --upgrade jinja2

And then I could perfectly install the Kubernates cluster using Kargo
