Automatically deploy FRP server and client services using Docker

It is an easy way to deploy FRP server and client services using Docker, which simplifies the setup process by breaking it down into four parts.

function display_menu {
    echo "Please select a service as you want to deploy:"
    echo "1. FRP(S) Service"
    echo "2. FRP(C) Service"
    echo "0. Exit"
}

The script starts with a menu that presents the user with three options to choose from. This menu is essential to guide the user through the rest of the process.

function handle_option_1 {
}

This part sets up the FRP server service as a function.

include the following

if ! command -v docker &> /dev/null
then
    echo "Docker is not installed. Installing Docker now..."
    curl -O https://kingtam.win/usr/uploads/script/install-docker.sh && chmod +x install-docker.sh && ./install-docker.sh
fi

It detects if Docker is installed and if not, installs it.

echo "What port would you like to use for the frps service? Press enter to use the default port of 7000, type 'r' to generate a random port, or enter a port number:"
read -r port_choice

if [[ $port_choice == "r" ]]; then
    port=$(shuf -i 7001-9000 -n 1)
elif [[ -z $port_choice ]]; then
    port=7000
else
    port=$port_choice
fi
echo "What port would you like to use for the HTTP service? Press enter to use the default port of 80, or enter a port number:"
read -r http_choice

if [[ -z $http_choice ]]; then
    http=80
else
    http=$http_choice
fi
echo "What port would you like to use for the HTTPS service? Press enter to use the default port of 443, or enter a port number:"
read -r https_choice

if [[ -z $https_choice ]]; then
    https=443
else
    https=$https_choice
fi
echo "Would you like to generate a random token or enter a password for the frps service? Press enter to generate a random token, or enter a password:"
read -r token_choice

if [[ -z $token_choice ]]; then
    token=$(openssl rand -hex 16)
else
    token=$token_choice
fi

Then it prompts the user to create the FRP server service, HTTP, HTTPS, and token.

if [ ! -d "./frps/tmp" ]; then
    mkdir -p "./frps/tmp"
else
    sudo rm -rf "./frps" && mkdir -p "./frps/tmp"
fi

It also checks if the folder ./frps/tmp exists and creates it if it doesn't.

        restart: always
        volumes:
            - "$PWD/frps/frps.ini:/etc/frp/frps.ini"
            - "$PWD/frps/tmp:/tmp:rw"
EOF

docker-compose -f "./frps/docker-compose.yml" up -d

sleep 3
sudo cat "./frps/tmp/frps.log"

echo -e "\033[1;32mServer IP Address:\033[0m $(curl -s ifconfig.co)"
echo -e "\033[1;32mService Port:\033[0m $port"
echo -e "\033[1;32mToken:\033[0m $token"
echo -e "\033[1;32mHTTP Port:\033[0m $http"
echo -e "\033[1;32mHTTPS Port:\033[0m $https"

Finally, it creates the FRP server config file, docker-compose.yml file, starts up the docker-compose, and prints the frps.log with information in color.

function handle_option_2 {
}

This part sets up the FRP client service as a function.

include the following

if ! command -v docker &> /dev/null
then
    echo "Docker is not installed. Installing Docker now..."
    curl -O https://kingtam.win/usr/uploads/script/install-docker.sh && chmod +x install-docker.sh && ./install-docker.sh
fi

It also detects if Docker is installed and installs it if it isn't.

read -p "Enter the FRP(S) Server ip address or domain: " frpsip
read -p "Enter the FRP(S) Service port (press Enter for default **7000** or manual to input a port): " port
if [ -z "$port" ]
then
    port=7000
else
    read -p "Enter the FRP(S) Service port: " port
fi

read -p "Enter the FRP(S) Service token: " token

read -p "Enter the port of FRP(C) admin console (press Enter for default **7400** or manual to input a port): " cport
if [ -z "$cport" ]
then
    cport=7400
else
    read -p "Enter the FRP(C) admin console port: " cport
fi

read -p "Enter the username of FRP(C) console (press Enter for default **admin** or manual to input a name): " cname
if [ -z "$cname" ]
then
    cname=admin
else
    read -p "Enter the username of FRP(C) console: " cname
fi

echo "Would you like to generate a Random Console Password (Press Enter) or enter a password for the FRP(C) console?"
read cpasswd

if [[ -z $cpasswd ]]; then
    ctoken=$(openssl rand -hex 12)
else
    ctoken=$cpasswd
fi

Then the user is prompted to create the FRP client service, FRP server IP address or domain, port, token, admin address, console, and console token.

if [ ! -d "./frpc/tmp" ]; then
    mkdir -p ./frpc/tmp
else
    sudo rm -rf ./frpc && mkdir -p ./frpc/tmp
fi

It also checks if the folder ./frpc/tmp exists and creates it if it doesn't.

cat >> frpc/frpc.ini << EOF
[common]
server_addr = $frpsip
server_port = $port
token = $token
log_file = /tmp/frpc.log
log_level = info

        restart: always
        volumes:

docker-compose -f ./frpc/docker-compose.yml up -d

sleep 3
sudo cat ./frpc/tmp/frpc.log

echo -e "Please use below information to Login console and setup your FRP(C) services"
echo -e "The address of console: \033[1;32mhttp://localhost:$cport\033[0m"
echo -e "The username of console: \033[1;32m$cname\033[0m"
echo -e "The password of console: \033[1;32m$ctoken\033[0m"

Finally, it creates the FRP client config file, docker-compose.yml file, starts up the docker-compose, and prints the frpc.log with information in color.

display_menu

read -p "Enter your choice [0-2]: " choice

case $choice in
    1)
        handle_option_1
        ;;
    2)
        handle_option_2
        ;;
    0)
        echo "Exiting..."
        exit 0
        ;;
    *)
        echo "Invalid choice"
        ;;
esac

The case statement that evaluates the value of $choice and executes the corresponding code block. If the user enters a value that is not one of the three options, the * case matches and an error message is displayed.

• Save the contents of the script in a file, e.g., frp.sh.
• Make the script executable with chmod +x frp.sh.
• Run the script as root or with sudo: sudo ./frp.sh.

Also, We can using a single command line in the terminal. (Root Privileges is requires)

curl -O https://kingtam.win/usr/uploads/script/frp.sh && chmod +x frp.sh && ./frp.sh

This command will download the script from URL, make it executable, and then run it. If any of the commands fail, the subsequent commands will not be executed.

This bash script simplifies the deployment of FRP server and client services using Docker. Its four parts guide the user through the setup process, making it easy to create and run the services. By breaking down the process into manageable parts, this script reduces the complexity of the setup process for users.
