Containers are a lightweight alternative to fully virtualized machines (VMs). They use the kernel of the host system that they run on, instead of emulating a full operating system (OS). This means that containers can access resources on the host system directly. The runtime costs for containers is low, usually negligible. However, there are some drawbacks that need be considered:The above was sited from the Proxmox VE website.
### Download the Turnkey Core template To setup and install Docker in a Proxmox LXC Conainer, you will have to download the Turnkey Core template to your storage. 1\. Click on your storage then click on the templates button. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600627790061.png) 2\. Search for the core template and click download. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600627549435.png) 3\. When it's done you can click the "Create CT" button in the upper right corner. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600627916015.png) 4\. Set your hostname and password and be sure to UNCHECK "Unprivileged container" or this will not work. Now move on to the Template tab. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600627993814.png) 5\. Select the storage where you downloaded the Turnkey Core template then choose the template. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600628164202.png) 6\. In the Storage tab choose where you want the container to use storage. For the disk size I recommend at-least 20gb of space. This depends on what you plan on doing with the container. For example if you plan on downloading a bunch of files, you may want a larger size disk. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600628264965.png) 7\. On the CPU tab, I usually put 4 cores but this is overkill for a container. This depends on the processor you have in your system. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600628415695.png) 8\. On the Memory tab I usually allocate 2gb for containers. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600628541219.png) 9\. On the Network tab I let the DHCP host assign the IP automatically. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600628641571.png) 10\. On the DNS tab I just use my gateway IP. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600628692672.png) 11\. Confirm your settings and make sure you DO NOT tick "Start after created". Click finish and let the container create. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600628756760.png) 12\. Once done, you will see "TASK OK". Click the X in the upper corner and proceed to the next step. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600628834060.png) 13\. Select the container and then click on Options then double click on Features. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600629985611.png) 14\. Tick Nesting then click ok. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600629027165.png) 15\. Now you can start your container and view the console. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600629099543.png) This will start the container and run the install script then assign an IP to your container. Once done you will need to login using root and the password you chose when you created the container in step 4. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600629366205.png) 16\. Now we have to go through the Turnkey setup. Skip the API entry. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600629426391.png) 17\. Skip the notifications. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600629480902.png) 18\. Install security updates. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600629525146.png) This will take you to the final screen and will show you what the access IP and ports are for the appliance services. It's important to make a note of these incase you need them for future use. [](https://thehomelab.wiki/uploads/images/gallery/2020-09/image-1600629670008.png) 19\. Press CTRL+C to clear the console and now you can update the system by typing the commands below. Since we only use root in Proxmox, you do not need to use sudo for any commands through the console. ``` apt-get update ``` then ``` apt-get upgrade ``` ### Install Docker on your Promox Container Run the following commands one at a time. ``` apt install docker.io ``` ``` systemctl enable docker ``` ``` systemctl start docker ``` Now make sure Docker is running ``` systemctl status docker ``` ### Install Portainer This is completely optional but I wanted to add this in here just in-case you wanted a Docker UI. Run the following command to install Portainer 2.0 ``` docker run -d \ --name="portainer" \ --restart on-failure \ -p 9000:9000 \ -v /var/run/docker.sock:/var/run/docker.sock \ -v portainer_data:/data \ portainer/portainer-ce ``` Once completed, visit the IP of your container and port 9000. Example: 192.168.1.168:9000. If you forgot the IP of your container, open the console and type ``` ip addr ``` Press enter and find your container IP. It's usually towards the top.

Follow these steps to install docker in Proxmox 7 LXC. #### Install Docker via Script (recommended) This script is the [official Docker installer](https://github.com/docker/docker-install) maintained by Docker Inc. ``` curl -fsSL https://get.docker.com -o get-docker.sh sh get-docker.sh ``` #### Install Docker Manually Update the `apt` package index and install packages to allow `apt` to use a repository over HTTPS: ``` apt-get update ``` ``` apt-get install \ apt-transport-https \ ca-certificates \ curl \ gnupg \ lsb-release ``` Add Docker’s official GPG key: ``` curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg ``` Use the following command to set up the **stable** repository. To add the **nightly** or **test** repository, add the word `nightly` or `test` (or both) after the word `stable` in the commands below. [Learn about **nightly** and **test** channels](https://docs.docker.com/engine/install/). ``` echo \ "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian \ $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null ``` Update the `apt` package index, and install the *latest version* of Docker Engine and containerd. ``` apt-get update ``` ``` apt-get install docker-ce docker-ce-cli containerd.io ``` Verify docker is running on the system ``` systemctl status docker ``` # Add External USB Storage to Proxmox To use storage from an attached USB drive, we need to enter the Proxmox shell command line interface. There's just a few quick things we need to do, then you can enjoy your new external storage on Proxmox! ### Connect the USB Drive Make sure the USB drive is connected and ready to go. It's best that the drive is new and not used with files already on it. Also, once you plug it in to a USB port, you cannot change the port after we mount it. This is very important. So make sure you have it plugged into the right USB port. If you need to clear the drive you can do so using cfdisk. ``` cfdisk /dev/sdb ``` Make sure you change the drive accordingly to your own ID above. See below for how to find this information. ### Figure out what drive it is Find the drive device ID running this command ``` fdisk -l ```  Here we can see my 4TB USB drive. I had to scroll up pretty far in the terminal to find it. Here you can see the ID is sdb1. ### Create the filesystem If we tried mounting the drive without setting the filesystem, we would get an error like this > wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error. So to avoid this, we need to run the following command ``` mkfs.ext4 /dev/sdb1 ``` Make sure you change this to the correct device ID that matched your own drive. ### Create folder for mounting Now we have to make a folder where the drive will be mounted. I used the following folder. ``` mkdir /mnt/USB_Data ``` Now we mount the drive to it ``` mount /dev/sdb1 /mnt/USB_Data ``` ### Add the drive in Proxmox UI Now we go into Proxmox and add storage as a Directory using our new USB drive  Give it a name (any name should work). The Directory MUST be the folder where the new drive was mounted. Click add.  You should now see your new drive and it should be ready to use. [](https://snip.lol/JipE3/ceHiHUfO42/raw.png) You most likely want the USB drive to automatically mount when you reboot or unplug and plug them back in. To accomplish this we need to run the following in the PVE shell. ```code apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2FAB19E7CCB7F415 echo "deb https://apt.iteas.at/iteas buster main" > /etc/apt/sources.list.d/iteas.list apt update apt install pve6-usb-automount ``` Did you find this helpful?

Or so you just don't have to remember the IP. Either way, adding another layer of security is a must. Especially if it's already baked into Proxmox. Why not use it? Enable TFA on Proxmox! Step 1: In the upper right corner click on "root@pam".  Step 2: Click "TFA"  Step 3: Click on "Randomize" a few times then open your favorite Authentication app. I use an app called [Authy](https://authy.com/). It's free and works great! You should be able to use any authentication app. Scan the QR code to add your Proxmox host to your authenticator app. [](https://snip.lol/JipE3/hUGepawi04/raw.png)  Step 4: Grab the code and plug it in on Proxmox where it says "Verification code" Step 5: Click "Apply".
