This blog post shows how to deploy kubernetes on a multi-node cluster. However it has some problems that can not allow its correct reproducibility.
As follows it is presented how to fix those issues.
In kubernetes-setup/master-playbook.yml change line
command: kubectl create -f https://docs.projectcalico.org/v3.4/getting-started/kubernetes/installation/hosted/calico.yaml
for this line:
command: kubectl create -f https://docs.projectcalico.org/v3.8/getting-started/kubernetes/installation/hosted/calico.yaml
In kubernetes-setup/master-playbook.yml, look for:
- name: Copy join command to local file
local_action: copy content="{{ join_command.stdout_lines[0] }}" dest="./join-command"
and change it for:
- name: Copy join command to local file
become: false
local_action: copy content="{{ join_command.stdout_lines[0] }}" dest="./join-command"
In kubernetes-setup/master-playbook.yml, look for:
- name: Configure node ip
lineinfile:
path: /etc/default/kubelet
line: KUBELET_EXTRA_ARGS=--node-ip={{ node_ip }
and change it for:
- name: Configure node ip
lineinfile:
create: yes
path: /etc/default/kubelet
line: KUBELET_EXTRA_ARGS=--node-ip={{ node_ip }
