Cloud-like ready to use on-premise DevOps tools

Kubernetes

• multinode cluster setup with separate master and nodes
• network configured with calico
• service type loadbalancer available with metallb
• dynamic persistent volumes provisioning for storageClass "nfs" (default class) available with nfs-client
• docker available on separate machine
• jenkins-x available on separate machine

CI/CD

• jenkins master with 2 connected slaves able to build docker images
• nexus package repository
• docker and docker repository
• chartmuseum helm repository

Prerequisites

1. on windows disable hyper-v
2. install virtualbox
3. install vagrant
4. install vagrant plugins:

• vagrant plugin install vagrant-cachier
• vagrant plugin install vagrant-vbguest
• vagrant plugin install vagrant-disksize

Kubernetes cluster

1. adjust number of nodes in cluster in vagrantfile (line (1..4).each do |i| config.vm.define "k8s-node-#{i}" do |d|) - default is 4 nodes
2. if not running ci/cd adjust disksize for each node in vagrantfile (line .disksize.size) - default is 30gb per node and 100gb for nfs storage on dev machine
3. vagrant up
4. wait for all machines to boot up - check their status via cmd - vagrant status
5. vagrant ssh dev
6. cd /vagrant/ansible
7. ansible-playbook -i inventory/dev dev.yml -v
8. ansible-playbook -i inventory/k8s k8smaster.yml -v
9. ansible-playbook -i inventory/k8s k8snode.yml -v
10. ansible-playbook -i inventory/k8s k8sprovision.yml -v
11. k8s cluster is available via kubectl on dev vm
12. docker is available on dev vm
13. jenkins-x is available on dev vm
14. nfs-server is available on dev vm on path /nfs-k8s
15. dev vm share /vagrant path with host machine - you can copy kubectl config there and setup kubectl on host machine

CI/CD machine

1. if not running kubernetes adjust disksize for machine in vagrantfile (line d.disksize.size = "100GB") - default is 100gb
2. vagrant up dev
3. vagrant ssh dev
4. cd /vagrant/ansible
5. ansible-playbook -i inventory/dev cicd.yml -v
6. in case of error (jenkins can sometimes not install plugins) retry previous command
7. jenkins is available from host machine on 192.168.56.89:8080 with user "admin" and password "admin"
8. nexus is available from host machine on 192.168.56.89:8081 with user "admin" and password "admin"
9. docker registry is available on dev vm as 192.168.56.89:5000
