Docker镜像批量导出和导入脚本

docker-export.sh

#!/bin/bash

# 设置导出镜像的目录
EXPORT_DIR="/root/images"

# 确保导出目录存在
mkdir -p "$EXPORT_DIR"

# 获取所有的镜像并导出

	# 分割镜像仓库名和标签
	IFS=":" read -r REPOSITORY TAG <<<"$IMAGE"

	# 将仓库名中的斜杠替换为下划线
	SAFE_REPOSITORY=${REPOSITORY//\//_}

	# 构造导出文件的名称
	EXPORT_FILE="${SAFE_REPOSITORY}_${TAG}.tar"
	EXPORT_PATH="$EXPORT_DIR/$EXPORT_FILE"

	# 检查镜像是否存在，如果存在则导出
	if docker image inspect "${REPOSITORY}:${TAG}" >/dev/null 2>&1; then
		docker save -o "$EXPORT_PATH" "${REPOSITORY}:${TAG}"
		echo "Exported ${REPOSITORY}:${TAG} to $EXPORT_PATH"
	else
		echo "Error: ${REPOSITORY}:${TAG} does not exist"
	fi
done

echo "Export process completed."

docker-inport.sh

#!/bin/bash

# 设置包含要导入镜像的 .tar 文件的目录
IMPORT_DIR="/root/images"

# 检查目录是否存在
if [ ! -d "$IMPORT_DIR" ]; then
	echo "Error: Directory $IMPORT_DIR does not exist."
	exit 1
fi

# 遍历目录下的所有 .tar 文件并导入
for TAR_FILE in "$IMPORT_DIR"/*.tar; do
