## Configuration steps for my Raspberry Pi

Configuration steps for RaspberryPi and deploy containers Docker: nginx, nginx-proxy, letsencrypt, duckddns and onwcloud

### Download image Ubuntu for RPI
- https://ubuntu.com/download/raspberry-pi
- https://ubuntu.com/tutorials/how-to-install-ubuntu-on-your-raspberry-pi#2-prepare-the-sd-card

#### Add local user
```bash
useradd -m -s /bin/bash adrian
usermod -G sudo adrian
passwd adrian
```
#### Delete user by default RPI
```bash
userdel -f ubuntu
```
#### Change hostname RPI
```bash
echo "rpi" > /etc/hostname
echo "IP rpi" >> /etc/hosts
```

#### nano editor config (.nanorc)
```bash
set tabsize 4
set autoindent
set smooth
set linenumbers
set nohelp
set softwrap
```

#### Disable grace period sudo
- /etc/sudoers
```bash
echo "Defaults timestamp_timeout=0" >> /etc/sudoers
```

#### Packages installation and requirements
```bash
apt update -y && apt install -y sysstat htop mlocate bat cifs-utils \
tmux p7zip-full p7zip-rar zip unzip tree fail2ban \
apache2-utils firefox python3 && \
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py && \
python get-pip.py && rm get-pip.py
```

#### Add aliases to my .bashrc
```bash
echo "alias cat='batcat'" >> $HOME/.bashrc
```

#### SSH server config
- /etc/ssh/sshd_config
```bash
PasswordAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
AllowUsers adrian
AllowTcpForwarding yes
GatewayPorts yes
X11Forwarding yes
AcceptEnv LANG LC_*
Subsystem sftp /usr/lib/openssh/sftp-server
```
```bash
systemctl enable ssh && systemctl restart ssh
```

#### SSH permission in directories and configure public key authentication
```bash
su - adrian
mkdir -p -m 700 ~/.ssh
touch ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys
(install -m 600 /dev/null ~/.ssh/authorized_keys)
```
> set public key (ssh-rsa ...pubkey... rsa-key-xxxxxxxx)
```bash
adrian@rpi:~$ tree -pugah
├── [drwx------ adrian adrian 4.0K] .ssh
│   └── [-rw------- adrian adrian 398] authorized_keys
└── [lrwxrwxrwx root root 14] sharedrpi -> /mnt/sharedrpi
```

#### fail2ban config

- /etc/fail2ban/jail.conf
```bash
ignoreip = 127.0.0.1/8 ::1 /
[sshd]
port = ssh
logpath = %(sshd_log)s
backend = %(sshd_backend)s
bantime = 172800
findtime = 600
maxretry = 3
```
```bash
systemctl enable fail2ban && systemctl restart fail2ban
```

#### Create shared and scripts folder
```bash
mkdir /mnt/sharedrpi
ln -s /mnt/sharedrpi /home/adrian/sharedrpi

mkdir /scripts && cd /scripts
git clone https://github.com/adrianlois/rpi-config-nginx-proxy-letsencrypt-duckdns-owncloud.git
mv rpi-config-nginx-proxy-letsencrypt-duckdns-owncloud/* . && mv scripts/* . && mv scripts/.[!.]* .
rm -rf rpi-config-nginx-proxy-letsencrypt-duckdns-owncloud/ docker/nginx/htpasswd scripts/ LICENSE README.md

chmod 600 .smbcredentials docker/.env
cp -r docker/nginx/.nginx-error-pages /home/adrian/sharedrpi/
```

#### Crontab config
```bash
chmod 700 /scripts/sharedrpi.sh
```
- /etc/crontab
```bash
# @reboot sleep 30 && /scripts/sharedrpi.sh
*/1 * * * * root /scripts/sharedrpi.sh
```

#### htpasswd file for nginx or apache2
```bash
htpasswd -c /scripts/docker/nginx/htpasswd USER
chmod 644 /scripts/docker/nginx/htpasswd
```

#### External USB format ext4 and mount for ownCloud
```bash
mkdir -m 777 /media/owncloud

fdisk -l
mkfs.ext4 /dev/sdaX

lsblk -o NAME,FSTYPE,SIZE /dev/sdaX
blkid -o list
(ls -l /dev/disk/by-uuid)
echo -e "\nUUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx /media/owncloud ext4 defaults 0 0" >> /etc/fstab
mount -a
```

### Install Docker & Docker Compose
- https://docs.docker.com/engine/install/ubuntu/
- https://docs.docker.com/compose/install/
```bash
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py && sudo python3 get-pip.py
apt install -y python3-pip libffi-dev
curl -sSL https://get.docker.com | sh
pip3 install docker-compose
```

#### Running docker without sudo from another user
```bash
sudo usermod -aG docker ${USER}
id -nG
```

#### Delay docker service startup at system boot

Start nginx containers after mounting the sharedrpi sharedrpi share (crontab script sharedrpi.sh).

```bash
sudo systemctl edit docker.service

[Service]
ExecStartPre=/bin/sleep 90
```

#### Deploy compatible docker containers for RaspberryPi

```bash
cd /scripts/docker
docker-compose up -d
```

*docker-compose.yaml*
- duckdns
- nginx
- nginx-proxy (80)
- owncloud (8080)
- mariadb
- redis

*docker-compose2.yaml*
- duckdns
- nginx
- nginx-proxy (80,443)
- letsencrypt

*docker-compose3.yaml*
