Deis-workflow v2 demo

• This is a deis-workflow v2 using Kubernetes on DigitalOcean demo, used in my Online course (www.newtech.academy)
• terraform scripts to launch instances on DigitalOcean
• ansible playbook is in ansible
• provision scripts for Deis can be found in scripts/

configuration

• Create terraform/terraform.tfvars

DO_TOKEN = "generate new api key and put here"
PUBLIC_SSH_KEY = "/path/to/.ssh/id_rsa.pub"
PRIVATE_SSH_KEY = "/path/to/.ssh/id_rsa"

• Create Ansible inventory file ansible/inventory:

[coreos]
ip1
ip2
ip3

[kubernetes-master]
ip1

[kubernetes-workers]
ip2
ip3

• Set variables in ansible/group_vars/all

how to run

• Spin up DigitalOcean instances:

$ cd terraform
$ terraform apply

• Run the ansible playbook

$ cd ansible
$ ansible-playbook kubernetes.yml -i inventory

• Install kubectl

$ scripts/kubectl.sh

• Install Deis

$ scripts/install_deis.sh

• Install Deis client

$ scripts/install_client.sh

• Start the LB. First find out the EndPoints and change them in config

kubectl describe service deis-router --namespace=deis
# edit group_vars/all
# edit inventory file
ansible-playbook kubernetes.yml -i inventory --limit loadbalancer-ip

• Register to Deis and Deploy the app

$ deis register http://deis.public-ip.nip.io
$ mv demo-app ../app && cd ../app
$ git init
$ git add .
$ git commit -am "initial commit"
$ deis create
$ deis keys:add
$ ssh-agent bash
$ ssh-add ~/.ssh/mykey
$ git push deis master
$ curl appname.public-ip.nip.io
