```

### Proxmox Container Creation

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

```bash
pct create 100 /var/lib/vz/template/cache/openwrt-rootfs.tar.xz --unprivileged 1 --arch amd64 --ostype unmanaged --hostname openwrt-0 --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
```

### OpenWRT Firewall Configuration

```bash
passwd
```

```bash
vi /etc/config/network
```

```bash
config interface 'loopback'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'
        option device 'lo'

config interface 'wan'
        option proto 'dhcp'
        option device 'eth0'

config interface 'wan6'
        option proto 'dhcpv6'
        option device 'eth0'

config interface 'lan'
        option ifname 'eth1'
        option proto 'static'
        option device 'eth1'
        option ipaddr '10.0.0.1'
        option netmask '255.255.255.0'
```

```bash
130 j
```

```bash
vi /etc/config/firewall
```

```bash
config rule
    option name 'Allow-SSH'
    option src 'wan'
    option proto 'tcp'
    option dest_port '22'
    option target 'ACCEPT'

config rule
    option name 'Allow-HTTPS'
    option src 'wan'
    option proto 'tcp'
    option dest_port '443'
    option target 'ACCEPT'

config rule
    option name 'Allow-HTTP'
    option src 'wan'
    option proto 'tcp'
    option dest_port '80'
    option target 'ACCEPT'    
```

### Applying the Configuration

After updating the configuration files:

- **Restart Network Services**:
  ```bash
  /etc/init.d/network restart
  ```

- **Reload Firewall Settings**:
  ```bash
  /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:

```bash
opkg update
```

```bash
opkg install qemu-ga
```

```bash
poweroff
```

OpenWRT Container (ID: 100):
```bash
pct create 100 /var/lib/vz/template/cache/openwrt-rootfs.tar.xz --unprivileged 1 --arch amd64 --ostype unmanaged --hostname openwrt-0 --tag network --storage local-lvm --cores 2 --memory 128 --swap 0 --rootfs local-lvm:1,size=512M --net0 name=eth0,bridge=vmbr0,firewall=1 --net1 name=eth1,bridge=vmbr1,firewall=1
```
Kali Linux Container (ID: 200):
```bash
pct create 200 /var/lib/vz/template/cache/kali-default-rootfs.tar.xz --unprivileged 1 --arch amd64 --ostype debian --hostname kali-0 --tag tools --storage local-lvm --cores 2 --memory 1024 --swap 512 --rootfs local-lvm:1,size=8G --net0 name=eth0,bridge=vmbr1,firewall=1 
```
Alpine Container (ID: 300):
```bash
pct create 300 /var/lib/vz/template/cache/alpine-default-rootfs.tar.xz --unprivileged 1 --arch amd64 --ostype alpine --hostname alpine-0 --tag docker --storage local-lvm --cores 2 --memory 1024 --swap 256 --rootfs local-lvm:1,size=8G --net0 name=eth0,bridge=vmbr1,firewall=1
```

```bash
pct enter 300
```

```bash
passwd
```

```bash
pct console 300
```

```bash
sed -i '/^#.*community/s/^#//' /etc/apk/repositories
```

```bash
apk update && apk upgrade
```

```bash
reboot
```

```bash
setup-interfaces
```
Choose the appropriate network interface and configure it with DHCP or a static IP as required. Then:

```bash
service networking restart
```

```bash
apk add bash curl wget vim htop qemu-guest-agent
```

```bash
passwd
```

```bash
apk update && apk upgrade
```


```bash
cat /etc/apk/repositories
```

```bash
sed -i '/^#.*community/s/^#//' /etc/apk/repositories
```

or

```bash
vim /etc/apk/repositories
```

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

3. Install the required packages:

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

# Build Tools
```bash
apk add build-base gcc abuild binutils binutils-doc gcc-doc
```

4. Create a system user and add them to the docker group and sudoers:
   ```
   adduser -s /bin/ash medusa
   addgroup medusa docker
   visudo
   ```
   Add the following line to the sudoers file:
   ```
   medusa 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
   vim /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 - medusa
   ```

9. Test Docker functionality:
   ```
   docker run hello-world
   ```

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

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