（16）docker自动镜像打包脚本

注：

1.将写好的Dockerfile文件、脚本、前端包或后端包放在同一目录下；

2.基础镜像提前导入；

-----------------------------------

#!/bin/bash

# 定义脚本参数和变量
IMAGE_NAME="lisp-bpms-web"  # 替换为实际的镜像名称
DOCKERFILE_PATH="Dockerfile"  # 如果Dockerfile位置与脚本在同一目录，无需修改
CONTEXT_PATH="."              # 同上
SAVE_AS_TAR=true              # 根据需求决定是否保存为 tar 文件

# 获取当前时间戳作为镜像标签
TIMESTAMP=$(date +%Y%m%d%H%M%S)

# 构建带有时间戳的镜像
echo "Building Docker image with tag ${IMAGE_NAME}:${TIMESTAMP}"
docker build --tag "${IMAGE_NAME}:${TIMESTAMP}" -f "${DOCKERFILE_PATH}" "${CONTEXT_PATH}"

# 检查构建状态
if [ $? -ne 0 ]; then
    echo "Docker image build failed."
    exit 1
fi

# 保存镜像为 tar 文件（如果 SAVE_AS_TAR 设置为 true）
if [ "$SAVE_AS_TAR" = true ]; then
    echo "Saving Docker image as tar file"
    IMAGE_FILE="${IMAGE_NAME}_${TIMESTAMP}.tar"

    docker save "${IMAGE_NAME}:${TIMESTAMP}" -o "${IMAGE_FILE}"
    if [ $? -ne 0 ]; then
        echo "Failed to save Docker image as tar file."
        exit 1
    fi

    echo "Docker image saved as ${IMAGE_FILE}"
fi

echo "Docker image build and (optionally) save completed successfully."
