用于 Docker-Compose 多次执行的自定义脚本

Question

我对 Bash 比较陌生，我正在尝试清理内容并拥有更好的文件夹结构。

我目前正在尝试构建一个具有上下选项的脚本，例如著名的命令“

Docker-Compose Up

”和“

Docker-Compose Down

”

我唯一的问题是我不太熟悉 If 函数或是否有任何其他函数可以将 Up 和 Down 作为选项或参数

我当前的脚本如下

compose-up.sh

#!/bin/bash

sudo docker-compose -f /home/home/compose/tools.yml -f /home/home/compose/dashboards.yml up -d

compose-down.sh

#!/bin/bash

sudo docker-compose -f /home/home/compose/tools.yml -f /home/home/compose/dashboards.yml down

新脚本应命名为 compose.sh，我希望我可以直接输入

./compose.sh up

在 Docker 中运行和创建这些容器

./compose-sh down

停止并删除 Docker 中的这些容器

使其动态=理想的脚本

我的代码最大的设计缺陷是它不是动态的。这可能是一个更复杂的代码，需要改进，但如果有人更容易创建一个代码来基本上在特定目录（例如

Docker-Compose Up

）内的所有 xml 文件上运行

/home/home/compose

。例如，文件夹“compose”中的所有 xml 文件将自动 docker-compose up，如果我也想进行 docker-compose down

脚本

#!/bin/bash
This script is a bash script that manages Docker Compose operations such as starting, stopping, restarting, and pulling services defined in YAML files

# down() function stops and removes all Docker Compose containers defined in the YAML files in the current folder.

# @return: Outputs a message indicating whether the containers were successfully removed or if no containers were found.
down() {
    local yml_files=($(find "$(pwd)" -maxdepth 1 -name "*.yml"))  # Find all yml files in the current directory

    # Check if any YAML files are found
    if [ ${#yml_files[@]} -eq 0 ]; then
        echo "No yml files found in the current folder."
        exit 1
    fi

    local compose_files=""
    for file in "${yml_files[@]}"; do
        compose_files+="-f $file "  # Append each yml file to the command
    done

    local output=$(sudo docker-compose $compose_files down 2>&1)  # Capture the output of the command

    # Check if the output contains the message "No resource found to remove"
    if [[ $output == *"No resource found to remove"* ]]; then
        echo "No compose files are running in the current folder."
    else
        echo "All compose-related containers are removed in the current folder."
    fi
}

# up() function starts Docker Compose containers defined in the YAML files in the current folder.

# @return: No return value.
up() {
    local yml_files=($(find "$(pwd)" -maxdepth 1 -name "*.yml"))  # Find all yml files in the current directory

    # Check if any YAML files are found
    if [ ${#yml_files[@]} -eq 0 ]; then
        echo "No yml files found in the current folder."
        exit 1
    fi

    local compose_files=""
    for file in "${yml_files[@]}"; do
        compose_files+="-f $file "  # Append each yml file to the command
    done

    sudo docker-compose $compose_files up -d
}

# restart() function restarts Docker Compose containers defined in the YAML files in the current folder.

# @return: No return value.
restart() {
    local yml_files=($(find "$(pwd)" -maxdepth 1 -name "*.yml"))  # Find all yml files in the current directory

    # Check if any YAML files are found
    if [ ${#yml_files[@]} -eq 0 ]; then
        echo "No yml files found in the current folder."
        exit 1
    fi

    local compose_files=""
    for file in "${yml_files[@]}"; do
        compose_files+="-f $file "  # Append each yml file to the command
    done

    sudo docker-compose $compose_files restart
}

# stop() function stops Docker Compose containers defined in the YAML files in the current folder.

# @return: No return value.
stop() {
    local yml_files=($(find "$(pwd)" -maxdepth 1 -name "*.yml"))  # Find all yml files in the current directory

    # Check if any YAML files are found
    if [ ${#yml_files[@]} -eq 0 ]; then
        echo "No yml files found in the current folder."
        exit 1
    fi

    local compose_files=""
    for file in "${yml_files[@]}"; do
        compose_files+="-f $file "  # Append each yml file to the command
    done

    sudo docker-compose $compose_files stop
}

# pull() function stops and removes all Docker Compose containers, then starts new containers defined in the YAML files in the current folder.

# @return: No return value.
pull() {
    down
    up
}

# start() function starts Docker Compose containers defined in the YAML files in the current folder.

# @return: No return value.
start() {
    local yml_files=($(find "$(pwd)" -maxdepth 1 -name "*.yml"))  # Find all yml files in the current directory

    # Check if any YAML files are found
    if [ ${#yml_files[@]} -eq 0 ]; then
        echo "No yml files found in the current folder."
        exit 1
    fi

    local compose_files=""
    for file in "${yml_files[@]}"; do
        compose_files+="-f $file "  # Append each yml file to the command
    done

    sudo docker-compose $compose_files start
}

# main() function is the entry point of the script. It calls the appropriate function based on the user's input.

# @param $1: The command to execute (down, up, restart, stop, pull, start).
# @return: No return value.
main() {
    if [ "$1" == "down" ]; then
        down
    elif [ "$1" == "up" ]; then
        up
    elif [ "$1" == "restart" ]; then
        restart
    elif [ "$1" == "stop" ]; then
        stop
    elif [ "$1" == "pull" ]; then
        pull
    elif [ "$1" == "start" ]; then
        start
    else
        echo "Invalid option. Please choose one of the following: down, up, restart, stop, pull, start."
    fi
}

# Check if the script is being executed directly (not sourced) and call the main() function with the provided arguments.
if [[ "${BASH_SOURCE[0]}" == "${0}" ]]; then
    main "$@"
fi

我在一位老朋友的帮助下成功创建了一个 bash 代码，使我的代码变得动态。 享受:)

该脚本提供了常用 Docker Compose 命令的功能，例如 down、up、restart、stop、pull 和 start。

主要目标是能够基于 pwd 的当前文件夹自动化和运行 docker-compose 文件。

这些函数正确查找当前目录中的所有 YAML 文件，并将它们用作 Docker Compose 命令的输入。

添加到路径

1. sudo mv <CurrentPathofScript>/<ScriptName> /usr/local/bin/

2. sudo chmod 755 /usr/local/bin/<ScriptName>
