Linode VM

Prepair

Read first: Commands for Compute Instances

You can later set the Linode IDs as variables:

linode-cli linodes list
set "LID_1=38120280"
echo %LID_1%

Control them by changing a single number:

linode-cli linodes boot %LID_1%
linode-cli linodes reboot %LID_1%
linode-cli linodes shutdown %LID_1%

Create a new Linode VM

Gather some information:

linode-cli linodes types
linode-cli regions list
linode-cli images list

Maybe set the credentials as environment variables:

Note: Must be done in a seperate CMD session before starting a the linode-cli session!

setx ROOT_PASS "<PASSWORD>"
setx SSH_KEY "SSH_KEY=ssh-rsa <KEY> %USERNAME%"
echo %ROOT_PASS%
refreshenv
echo %ROOT_PASS%

VM creation command:

linode-cli linodes create --type "g6-nanode-1" --region "eu-west" --image "linode/ubuntu22.04" --root_pass "%ROOT_PASS%" --authorized_keys "%SSH_KEY%" --label "<VM_NAME>"

Now add a Linode Firewall and restrict the HTTP ports to your IP only!

Log in via SSH and add a user:

sudo adduser J2897 --force-badname
sudo usermod -aG sudo J2897
su - J2897

Note: Test this in the future if you have difficulty restoring a snapshot:

--authorized_keys "$(cat ~/.ssh/id_rsa.pub)"

Edit the sudoers file:

sudo visudo

Add this:

# Extend the password authentication timer to 5 hours.
Defaults:J2897 timestamp_timeout=300

Update everything:

sudo apt-get update;
sudo apt-get upgrade

Shut the VM down and create a snapshot.

If paid Backups are enabled, you can create a snapshot simply from the CLI:

linode-cli linodes snapshot --label "snapshot-1" "<LID>"

Install Docker:

Note: If you're using Debian, simply change all ubuntu words to debian.

sudo apt-get remove docker docker-engine docker.io containerd runc
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg lsb-release
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

Test:

sudo usermod -aG docker J2897
newgrp docker
docker run hello-world

If something goes wrong, restore snapshot-1 and then resize the disk.
