Build a Kubernetes cluster using Ansible with k3s. The goal is easily install a Kubernetes cluster on machines running:
- Debian
- Ubuntu
- CentOS
on processor architecture:
- x64
- arm64
- armhf
Deployment environment must have Ansible 2.4.0+ Master and nodes must have passwordless SSH access
First create a new directory based on the sample
directory within the inventory
directory:
$ cp -R inventory/sample inventory/cluster
...
Second, edit inventory/cluster/hosts.ini
to match the system information gathered above. For example:
[master]
192.16.35.12
[node]
192.16.35.[10:11]
[k3s_cluster:children]
master
node
If needed, you can also edit inventory/cluster/group_vars/all.yml
to match your environment.
For instance, the ansible_user
variable should probably be changed, as well as ansible_sudo_pass
if needed.
Start provisioning of the cluster using the following command:
$ ansible-playbook install.yml -i inventory/cluster/hosts.ini --extra-vars "ansible_sudo_pass=SPECIFY_PWD_HERE"
...
To get access to your Kubernetes cluster just
$ scp <USER>@master_ip:~/.kube/config ~/.kube/config
...
