Homelab

This repository attemps to collect all required scripts, playbooks, etc to setup my homelab. This is forever work in progress.

Setup Proxmox

Note

For the first execution, the password is required for ssh to proxmox nodes.
So run the playbook with additional argument -K. Thereafter the ssh authorized keys are set and password will not be required.

cd ansible
ansible-playbook proxmox.yml -K

Run terraform to provision VMs

Note

This need to be run for all sub directories in each of the terraform environments we want to provision for. So, for sub project in terraform-bgp/envrionment/

# as an example, to provison kubernetes VMs
cd terraform-bgp/environment/home/kubernetes
terraform init --upgrade
terraform plan

# optionally auto approve the apply ( --auto-approve )
terraform apply

Run ansible to setup VMs

cd ansible
ansible-playbook vm.yml

Usefull commands

Random tidbits that I need to run frequently enough that these are useful but not so frequently that I will remember these.

Generate basic auth password

echo $(htpasswd -nb "<USER>" "<PASSWORD>") | sed -e s/\\$/\\$\\$/g

SSH

Remove known hosts entry when recreating VMs

ssh-keygen -R <IP>

Copy the ssh to the server

Should not be required since VM's already copy the pre-seeded pubkey required.

# Run in windows command prompt / powershell
# Alternative to doing the same thing in ansible
ssh <user@hostname> "mkdir -p .ssh"
type $env:USERPROFILE\.ssh\id_rsa.pub | ssh <user@hostname> "cat >> .ssh/authorized_keys"

Ansible

Check if ansible is able to reach the servers

# if everything is set up
ansible all -m ping

# if ansible.cfg is not set up
ansible all --key-file ~/.ssh/ansible -i inventory -m ping

WSL

Ansible does not like world writable directory in WSL. Enable chmod and then remove write persmission from others.

sudo umount /mnt/c
sudo mount -t drvfs C: /mnt/c -o metadata
sudo chmod o-w <ANSIBLE_DIRECTORY>

Proxmox

Stop and remove VMs

qm stop <VM_ID>
qm destroy <VM_ID>

Terraform

Destroy all resources

terraform destroy

Git

Rebase and squash entire branch

git checkout --orphan new-master master
git commit -m "Enter commit message for your new initial commit"

# Overwrite the old master branch reference with the new one
git branch -M new-master master
