Proxmox Container Creation

Use the following command to create a new container with reduced memory and storage:

pct create 101 /var/lib/vz/template/cache/openwrt-rootfs.tar.xz --unprivileged 1 --arch amd64 --ostype unmanaged --hostname openwrt-01 --tag network --storage local-lvm --memory 128 --swap 0 --rootfs local-lvm:1,size=512M \
--net0 name=eth0,bridge=vmbr0,firewall=1 \
--net1 name=eth1,bridge=vmbr1,firewall=1

Applying the Configuration

After updating the configuration files:

• Restart Network Services:

  /etc/init.d/network restart
  

• Reload Firewall Settings:

  /etc/init.d/firewall restart
  

Installing Packages via CLI

1. Update the Package List: Before installing any new packages, it's a good practice to update the list of packages to ensure you are installing the latest versions available. You can do this by running:

opkg update

opkg install qemu-ga

poweroff

Here's a concise guide to set up a minimal Alpine Linux system with the specified packages and configurations:

1. Install Alpine Linux:
   - Download the Alpine Linux ISO from the official website.
   - Create a bootable USB drive or use a virtual machine.
   - Boot from the installation media and follow the installation wizard.

2. Update the system and add the community repository:

apk update apk add vim vi /etc/apk/repositories

Uncomment the line for the community repository, then save and exit.

3. Install the required packages:

apk add qemu-guest-agent htop docker curl wget iperf3 sudo

4. Create a system user and add them to the docker group and sudoers:

adduser -s /bin/ash myuser addgroup myuser docker visudo

Add the following line to the sudoers file:

myuser ALL=(ALL) ALL

Save and exit.

5. Start and enable the Docker service:

rc-update add docker default service docker start

6. Install and configure SSH:

apk add openssh rc-update add sshd service sshd start vi /etc/ssh/sshd_config

Uncomment and modify the following lines:

PermitRootLogin no PasswordAuthentication yes

Save and exit.

7. Restart the SSH service:

service sshd restart

8. Log in as the newly created user:

su - myuser

9. Test Docker functionality:

docker run hello-world

10. Test sudo privileges:
 ```
 sudo apk update
 ```

11. Connect to the system via SSH:
 ```
 ssh myuser@<server-ip>
 ```

Additional notes:
- Make sure to set a strong password for the user account.
- Consider using SSH key-based authentication for enhanced security.
- Regularly update the system and installed packages using `apk update` and `apk upgrade`.
- Configure the system as per your specific requirements and security best practices.

This guide provides a basic setup for a minimal Alpine Linux system with the requested packages and configurations. Feel free to customize it further based on your needs.
