TO DO

  • Save state in Gitlab?

Quick

Set up silly alias, to this really quickly and easy

tee -a ~/.bash_aliases <<EOF
alias htz_up="terraform -chdir=/home/rihards/Code/cloud_project/cloud_project_terraform_hetzner/ apply -target=hcloud_server.htz1 -auto-approve"
alias htz_down="terraform -chdir=/home/rihards/Code/cloud_project/cloud_project_terraform_hetzner/ destroy -target=hcloud_server.htz1 -auto-approve"
alias htz_ssh="ssh rudenspavasaris.id.lv -o StrictHostKeyChecking=no -o 'UserKnownHostsFile=/dev/null'"
alias htz_ansible="ansible-playbook -i $(terraform -chdir=/home/rihards/Code/cloud_project/cloud_project_terraform_hetzner/ output -raw ip), \
    -e node_ip_address=$(terraform -chdir=/home/rihards/Code/cloud_project/cloud_project_terraform_hetzner/ output -raw ip) \
    -u rihards --diff -e ansible_python_interpreter=/usr/bin/python3 -e ansible_port=22 \
    /home/rihards/Code/cloud_project/cloud_project_ansible/htz1.yml"
EOF

Start

Create token in Hetzner Cloud -> Security -> Tokens Create terraform.tfvars file with the Hetzner token. Like this:

hcloud_token = "TOKEN_GOES_HERE"

Run terraform init -upgrade to get latest provider version that takes the correct server sizes

Create dependencies - firewall and ssh key, as I'm going to do as one shouldn't: using targets. Eh

terraform -chdir=/home/rihards/Code/cloud_project/cloud_project_terraform_hetzner/ apply -target=hcloud_ssh_key.hetzner_key -target=hcloud_firewall.firewall -auto-approve

Provision with ansible manually, when something fails

SERVER_IP=rudenspavasaris.id.lv
export ANSIBLE_HOST_KEY_CHECKING=False && export ANSIBLE_SSH_RETRIES=5 && \
ansible-playbook -i ${SERVER_IP}, \
-e node_ip_address=${SERVER_IP} \
--diff -e ansible_python_interpreter=/usr/bin/python3 -e ansible_port=22 \
/home/rihards/Code/cloud_project/cloud_project_ansible/htz1.yml

Firewall rollout

Needed to update the provider, as I hadn't ran this is in a long time. terraform state replace-provider registry.terraform.io/-/hcloud hetznercloud/hcloud Needed to also add the terraform required_providers block.

cd ~/Code/cloud_project/cloud_project_terraform_hetzner
terraform apply -target=hcloud_firewall.firewall
terraform apply -target=hcloud_server.node1

Temporary worker node

cd ~/Code/cloud_project/cloud_project_terraform_hetzner
terraform apply -target=hcloud_server_network.htz2_srv_net -target=hcloud_server.htz2

terraform destroy -target=hcloud_server.htz2 -target=hcloud_server_network.htz2_srv_net

Temporary Minecraft node

cd ~/Code/cloud_project/cloud_project_terraform_hetzner terraform apply -auto-approve -target=hcloud_server.minecraft

cd ~/Code/cloud_project/cloud_project_terraform_hetzner terraform destroy -auto-approve -target=hcloud_server.minecraft
