raspberry-pi-dramble/tasks/k8s-services.yml : urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='localhost', port=80): Max retries exceeded about raspberry-pi-dramble HOT 21 CLOSED

Tried adding sym link as noted in issues 195 & 184 and did not resolve the issue. Not sure what to try?

from raspberry-pi-dramble.

One thing I changed was in setup/networking/templates/hosts.j2

and changed line 12 to be
192.168.0.{{ 49 + loop.index }} kube{{ loop.index }} kube{{ loop.index }}.pidramble.com

That didn't quite fix my problem, but I think I was having an issue because I was trying to run Ansible in WSL on Windows.

When I switched to my linux machine, I was able to succsfully run the playbook.

from raspberry-pi-dramble.

Following is the IP addresses I decided to use and coded in my setup/networking/inventory file :
[dramble]
192.168.1.221
192.168.1.222
192.168.1.223
192.168.1.224

[dramble:vars]
ansible_ssh_user=pi

Below it the hosts.j2 settings

127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

127.0.1.1 {{ dramble_hostname }}

{# Add an entry for each host in the cluster, using the loop index to map IPs #}
{% for host in groups['dramble'] %}
192.168.1.{{ 200 + loop.index }} kube{{ loop.index }} kube{{ loop.index }}.pidramble.com
{% endfor %}

I am assuming this is correct as the network setup ansible worked.

from raspberry-pi-dramble.

Also when I go to kube1 thru 4 and look at the /etc/hosts it looks correct. Here is what is in kube1 hosts file

127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

127.0.1.1 kube1.pidramble.com

192.168.1.201 kube1 kube1.pidramble.com
192.168.1.202 kube2 kube2.pidramble.com
192.168.1.203 kube3 kube3.pidramble.com
192.168.1.204 kube4 kube4.pidramble.com
192.168.1.223 registry.pidramble.test

from raspberry-pi-dramble.

Sure it all depends on your network configuration. Just make the starting loop index one less than what you want to start with.

This was the only place where 10.0.100.X netmask is hardcoded.

from raspberry-pi-dramble.

The hosts files are correct on the PI's so I am assuming it worked correct. Since I started at 201 I updated hosts.j2 with the following

192.168.1.{{ 200 + loop.index }} kube{{ loop.index }} kube{{ loop.index }}.pidramble.com

from raspberry-pi-dramble.

I don't believe networking is the issue. Will post the ansible playbook response with the -vvv option

from raspberry-pi-dramble.

When running with the -vvv option it is very verbose so I have attached a file with the results. I think the error may be:

fatal: [kube1 -> 192.168.1.221]: FAILED! => changed=false
module_stderr: |-

Searching the above error resulted in Issue 201 where the resolution was they were running the wrong ansible version. Unfortunately the issue did not state what version was causing the issue and what version resolved it.

I'm running the following:
ansible 2.9.6
config file = /home/jdalke/raspberry-pi-dramble/ansible.cfg
configured module search path = ['/home/jdalke/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python3/dist-packages/ansible
executable location = /usr/bin/ansible

You could look into installing a later version of Ansible directly from pip.

https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html#upgrading-from-ansible-3-or-ansible-core-2-10

The only other thing I've changed is to a more recent version of Kubernetes in vars/main.yml

kubernetes_version: '1.22'
kubernetes_packages:
  - name: kubelet=1.22.1-00
    state: present
  - name: kubectl=1.22.1-00
    state: present
  - name: kubeadm=1.22.1-00
    state: present
  - name: kubernetes-cni
    state: present

PIP3 install did not work on Unbuntu as after the install the ansible --version gave me nothing. Installed using APT:
sudo add-apt-repository --yes --update ppa:ansible/ansible-2.10

Ansible version -
ansible [core 2.11.4]
config file = /home/jdalke/raspberry-pi-dramble/ansible.cfg
configured module search path = ['/home/jdalke/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /home/jdalke/.local/lib/python3.8/site-packages/ansible
ansible collection location = /home/jdalke/.ansible/collections:/usr/share/ansible/collections
executable location = /usr/bin/ansible
python version = 3.8.10 (default, Jun 2 2021, 10:49:15) [GCC 9.4.0]
jinja version = 2.10.1
libyaml = True

Also update the vars/main.yml as directed and now getting the following error:

statically imported: /home/jdalke/raspberry-pi-dramble/tasks/k8s-services.yml
redirecting (type: modules) ansible.builtin.k8s to kubernetes.core.k8s
ERROR! couldn't resolve module/action 'k8s'. This often indicates a misspelling, missing collection, or incorrect module path.

The error appears to be in '/home/jdalke/raspberry-pi-dramble/tasks/k8s-services.yml': line 10, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

• name: Apply metrics-server manifest to the cluster.

Running ansible-galaxy install -r requirements.yml provides the following so assuming everything okay

Also I'm assuming I installed PIP3 under sudo as I can run PIP3 commands.

What version of linux are you running?

Downgraded to Ansible 2:10 and past first error and right back where I started:

TASK [Apply metrics-server manifest to the cluster.] ***************************************************************************************************************
fatal: [kube1 -> kube1]: FAILED! => changed=false
msg: 'Failed to get client due to HTTPConnectionPool(host=''localhost'', port=80): Max retries exceeded with url: /version (Caused by NewConnectionError(''<urllib3.connection.HTTPConnection object at 0x7f8ef8eef0>: Failed to establish a new connection: [Errno 111] Connection refused''))'

Very frustrating when these playbooks crap and your new to ansible. Looking at what the metrics-server is trying to do.
