Docker 构建镜像、推送、启动实用脚本

misc

存储多份 docker 认证信息：

mkdir "~/.project1"
mkdir "~/.project2"

docker --config ~/.project1 login registry.example.com -u <username> -p <deploy_token>
docker --config ~/.project2 login registry.example.com -u <username> -p <deploy_token> 

使用：

docker --config ~/.project1 pull registry.example.com/project1
docker --config ~/.project2 pull registry.example.com/project2

get-version.sh

#!/bin/sh

# Get the current datetime in the desired format (YYYY-MM-DD-HHMM)
CURRENT_DATETIME=$(TZ="Asia/Shanghai" date +'%Y_%m_%d_%H_%M')

# Get the abbreviated Git commit hash
GIT_COMMIT=$(git rev-parse --short HEAD)

# Combine the datetime and Git commit hash to generate the tag
TAG="${CURRENT_DATETIME}-${GIT_COMMIT}"

# Print the generated tag
echo "${TAG}"

build-image.sh

support command:

# only build
./build-image.sh 
# build and push
./build-image.sh -u xxx -p xxx --push

build-image.sh (remember to replace xxx with true value)：

#!/bin/sh
# Docker注册表
REGISTRY=xxx
REGISTRY_URL=https://$REGISTRY

# 镜像名称和标签
IMAGE=$REGISTRY/xxx/$(basename "$(pwd)")
IMAGE_TAG=$(./get-version.sh)

# Dockerfile文件位置
DOCKERFILE_PATH=./Dockerfile

# Initialize variables for user input
username=""
password=""
push=false

# Process command-line arguments
while [ $# -gt 0 ]; do
  case $1 in
    -u)
      shift
      username=$1
      ;;
    -p)
      shift
      password=$1
      ;;
    --push)
      push=true
      ;;
    *)
      echo "Unknown argument will be ignored: $1"
      ;;
  esac
  shift
done

# Print the parsed values
echo "username: $username"
echo "push: $push"


# 构建镜像
echo "Building image: "${IMAGE}:${IMAGE_TAG}
docker build ${BUILD_CONTEXT} -t ${IMAGE}:${IMAGE_TAG} -f $DOCKERFILE_PATH .
docker tag ${IMAGE}:${IMAGE_TAG} ${IMAGE}:latest

if [ "$push" = true ]; then
  echo "push is true. Performing push operation..."

  # 登录
  echo "Logging into registry..."
  docker login -u $username -p $password $REGISTRY_URL

  # 推送
  echo "Pushing to registry..."
  docker push ${IMAGE}:${IMAGE_TAG} 
  docker push ${IMAGE}:latest

  echo "Build and push complete!"
else
  echo "push is false. Skipping push operation."
  echo "Build complete!"
