Push Docker Images to Private Registry

Tips：When install images, you need open the proxy, but you must close it before push.

Extract Images Name to File

From the Helm's values.yaml, extract the images name and tag to images.tmp.

Usage：get_images.sh values-nginx.yaml

#!/bin/bash

# * Email         : liuxp731@qq.com
# * Create time   : 2024-09-13 16:06
# * Filename      : get_images.sh
# * Description   : Extracts Docker image names and tags from a YAML file and writes them to images.tmp
# **********************************************************

# 检查是否传入文件名作为参数
if [ "$#" -ne 1 ]; then
  echo "用法: $0 <values-nginx.yaml>"
  exit 1
fi

# 从命令行参数获取文件名
input_file="$1"

# 清空或创建 images.tmp 文件
> images.tmp

while read -r line; do
  if [[ $line == *"repository:"* ]]; then
    repository=$(echo $line | cut -d':' -f2 | xargs)
  elif [[ $line == *"tag:"* ]]; then
    tag=$(echo $line | cut -d':' -f2 | xargs)
    # 将结果写入 images.tmp 文件
    echo "$repository:$tag" >> images.tmp
  fi
done < "$input_file"

Pull Docker Images

Install all dcoker images in images.tmp file, one by one. If you have else docker images_list file, you can use it instead, just confirm every lines only has one docker image name.

Usage：pull_images.sh images.tmp

#!/bin/bash

# * Email         : liuxp731@qq.com
# * Create time   : 2024-09-13 16:34
# * Filename      : pull_images.sh
# * Description   : Pull images from Internet
# **********************************************************

# 检查是否传入文件名作为参数
if [ "$#" -ne 1 ]; then
  echo "用法: $0 <images.tmp>"
  exit 1
fi

# 从命令行参数获取文件名
input_file="$1"

# 读取文件并拉取每个镜像
while read -r image; do
  if [ -n "$image" ]; then
    echo "正在拉取镜像: $image"
    docker pull "$image"
  fi
done < "$input_file"

Rename Docker Images

The modified image names will be saved in the new_images.tmp file. And you can modify the private_registry to change the registry you want to push to.

Usage：update_images.sh images.tmp

#!/bin/bash
# **********************************************************
# * Author        : Burgess Leo
# * Email         : liuxp731@qq.com
# * Create time   : 2024-09-13 16:06
# * Filename      : update_and_tag_images.sh
# * Description   : Updates image paths and tags Docker images based on a specified file
# **********************************************************

# 检查是否传入文件名作为参数
if [ "$#" -ne 1 ]; then
  echo "用法: $0 <images.tmp>"
  exit 1
fi

# 从命令行参数获取文件名
input_file="$1"
output_file="new_images.tmp"
private_registry="192.167.3.18/"

# 创建或清空输出文件
> "$output_file"

# 处理文件内容并执行 docker tag 命令
while IFS= read -r original_image; do
  # 检查行是否为空
  if [[ -n "$original_image" ]]; then
    # 在镜像名称前加上私有仓库地址
    new_image_name="${private_registry}${original_image}"
    
    # 输出正在标记的镜像信息
    echo "正在标记镜像: docker tag $original_image $new_image_name"
    
    # 执行 docker tag 命令
    docker tag "$original_image" "$new_image_name"
    
    # 将新的镜像名称写入输出文件
    echo "$new_image_name" >> "$output_file"
  fi
done < "$input_file"

echo "所有镜像已成功标记并保存到 $output_file"

After Tag docker images, you must check the new_images_name.tmp, ensure the image names are correct. And you must confirm about projects created in your private harbor.

Push Images

Push images to a remote registry. This script reads a list of image names from a file named "new_images.tmp", and pushes them to a remote registry.

Usage：push_images.sh new_images.tmp

#!/bin/bash
# **********************************************************
# * Author        : Burgess Leo
# * Email         : liuxp731@qq.com
# * Create time   : 2024-09-14 09:01
# * Filename      : push_images.sh
# * Description   : Push Docker images to a registry
# **********************************************************

# 检查是否传入文件名作为参数
if [ "$#" -ne 1 ]; then
  echo "用法: $0 <images.tmp>"
  exit 1
fi

# 从命令行参数获取文件名
images_file="$1"
target_registry="192.167.3.18/library/"

# 遍历images.tmp文件中的每一行
while IFS= read -r line; do
    # 检查行是否为空
    if [ -z "$line" ]; then
        continue
    fi

    # 打印操作信息
    echo "正在推送镜像: $line"

    # 推送镜像
    docker push "$line"

done < "$images_file"

echo "所有指定的镜像已被推送。"

Delete Images from Local

Delete images from local.

Usage：delete_images.sh new_images.tmp

#!/bin/bash
# **********************************************************
# * Author        : Burgess Leo
# * Email         : liuxp731@qq.com
# * Create time   : 2024-09-14 09:02
# * Filename      : delete_images.sh
# * Description   : Delete images that pushed
# **********************************************************

# 检查是否有参数传递
if [ $# -ne 1 ]; then
    echo "Usage: $0 <path-to-file>"
    exit 1
fi

# 指定包含镜像名称的文件路径
images_file="$1"

# 检查文件是否存在
if [ ! -f "$images_file" ]; then
    echo "Error: File '$images_file' not found."
    exit 1
fi

# 逐行读取文件中的镜像名称
while IFS= read -r image; do
    # 删除镜像，忽略不存在的镜像
    if docker rmi "$image" &>/dev/null; then
        echo "Image $image has been deleted."
    else
        echo "Image $image does not exist or could not be deleted."
    fi
done < "$images_file"

echo "All listed images have been processed."
