It uses ansible and requires very little intervention. + +## Getting Started +The following steps aim to describe the minimum required to successfully run this script. + + +### Prerequisites + +Kubernetes and Ansible should be installed on the master node and docker and kubelet services should be running on the master and worker nodes. + + +### Setup +In order to configure the cluster an inventory file should be included. The inventory file (e.g.,`hosts`) has the following structure: + +``` +[master] +master ansible_host={enter-master-ip} ansible_connection=ssh ansible_ssh_user={insert-user} ansible_ssh_pass={insert-password} ansible_ssh_common_args='-o StrictHostKeyChecking=no' + +[workers] +worker ansible_host={enter-master-ip} ansible_connection=ssh ansible_ssh_user={insert-user} ansible_ssh_pass={insert-password} ansible_ssh_common_args='-o StrictHostKeyChecking=no' + +``` +In this configuration file, connection details should be filled in. In case more nodes within the cluster are needed, add lines as necessary to the workers group within the `hosts` file. + + +### Usage +In order to use the script, download or clone [this repository] (https://gerrit.opnfv.org/gerrit/vswitchperf) to the root of what will be the master node. + +Navigate to its contents and execute the following command as regular user (this will prevent errors throughout configuration and deployment) on whichever machine you wish to use as the master node (this host will be the one running kubectl): + +``` +ansible-playbook k8sclustermanagement.yml -i hosts –tags “deploy” + +``` +You can verify the installation by running: +``` +kubectl get nodes +``` +And verifying the readiness of the nodes. More information may be obtained with `kubectl describe nodes` if needed. + + +To clear the cluster, execute the following command + +``` +ansible-playbook k8sclustermanagement.yml -i hosts_garr –tags “clear” +``` + +To deploy only CNI plugins + +``` +ansible-playbook k8sclustermanagement.yml -i hosts_garr –tags “cni” +``` + + + +### Debugging + +In case a step goes wrong within the installation, ansible should display a message, however, there's also files to debug if the installation had something to do within k8s. In the case of the master node, we should be able to find a `log_init.txt` with necessary logs. On worker nodes, the relevant file is `node_joined.txt`. diff --git a/tools/k8s/cluster-deployment/k8scluster/ansible.cfg b/tools/k8s/cluster-deployment/k8scluster/ansible.cfg new file mode 100644 index 00000000..0cbe08f3 --- /dev/null +++ b/tools/k8s/cluster-deployment/k8scluster/ansible.cfg @@ -0,0 +1,9 @@ +[defaults] +interpreter_python=/usr/bin/python3 + +# enable logging +log_path = ./cluster-deployment.log + +[ssh_connection] +pipelining = True + diff --git a/tools/k8s/cluster-deployment/k8scluster/hosts b/tools/k8s/cluster-deployment/k8scluster/hosts new file mode 100644 index 00000000..dd928a8e --- /dev/null +++ b/tools/k8s/cluster-deployment/k8scluster/hosts @@ -0,0 +1,5 @@ +[master] +master ansible_host=10.10.120.22 ansible_connection=ssh ansible_ssh_user=ENTER_USER ansible_ssh_pass=ENTER_PASS ansible_ssh_common_args='-o StrictHostKeyChecking=no' + +[workers] +worker ansible_host=10.10.120.21 ansible_connection=ssh ansible_ssh_user=ENTER_USER ansible_ssh_pass=ENTER_PASS ansible_ssh_common_args='-o StrictHostKeyChecking=no' diff --git a/tools/k8s/cluster-deployment/k8scluster/k8sclustermanagement.yml b/tools/k8s/cluster-deployment/k8scluster/k8sclustermanagement.yml new file mode 100644 index 00000000..5430bed5 --- /dev/null +++ b/tools/k8s/cluster-deployment/k8scluster/k8sclustermanagement.yml @@ -0,0 +1,4 @@ +---
