# Linode VM

## Prepair

Read first: [Commands for Compute Instances](https://www.linode.com/docs/products/tools/cli/guides/linode-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](https://www.linode.com/docs/guides/disks-and-storage/#resizing-a-disk).
