在windows上使用docker

1. 安裝docker for window

2. 啟動wsl，並安裝ubuntu18.04版本(如果安裝不同版本，在後續的docker的設定上會有錯誤出現)

3. 依照這個網頁來實做

   1. Install Docker

      # Update the apt package list.
      sudo apt-get update -y
      
      # Install Docker's package dependencies.
      sudo apt-get install -y \
          apt-transport-https \
          ca-certificates \
          curl \
          software-properties-common
      
      # Download and add Docker's official public PGP key.
      curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
      
      # Verify the fingerprint.
      sudo apt-key fingerprint 0EBFCD88
      
      # Add the `stable` channel's Docker upstream repository.
      #
      # If you want to live on the edge, you can change "stable" below to "test" or
      # "nightly". I highly recommend sticking with stable!
      sudo add-apt-repository \
         "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
         $(lsb_release -cs) \
         stable"
      
      # Update the apt package list (for the new apt repo).
      sudo apt-get update -y
      
      # Install the latest version of Docker CE.
      sudo apt-get install -y docker-ce
      
      # Allow your user to access the Docker CLI without needing root access.
      sudo usermod -aG docker $USER

      2. Install Docker Compose

         # Install Python 3 and PIP.
         sudo apt-get install -y python3 python3-pip
         
         # Install Docker Compose into your user's home directory.
         pip3 install --user docker-compose

      3. 將 $HOME/.local/bin is set on your WSL $PATH

         sudo vi ~/.profile
         # 在最後一行新增
         export PATH="$PATH:$HOME/.local/bin"
         # 存檔
         source ~/.profile #使設定生效

      4. 讓wsl連到window上的docker

         echo "export DOCKER_HOST=tcp://localhost:2375" >> ~/.bashrc && source ~/.bashrc

      5. docker在window上預設不能掛載subfolder，只能掛載內建預設的volume，所以如果需要複製檔案進container，要在dockerfile用cpoy的方式進行

      6. 如果要使用subfolder，要進行以下設定(版本為ubuntu18.04)

         sudo vi /etc/wsl.conf

         # Now make it look like this and save the file when you're done:
         [automount]
         root = /

         存檔後logout或是restart即可

4. 如果有在windows中編輯*.sh檔，要注意，檔案的製作需要在linux的環境下創立，而且最後不能有enter

   ，不然容易會有結尾符號linux不認識，導致container crash(如果在window下編輯，更新完後需要透過wsl用vi/nano重新複製一份)

5. 將需要的dockerfile以及docker-compose.yaml準備好

6. 啟動的方式建議不要使用快取

   docker-compose build --no-cache
   docker-compose up --force-recreate #這行為強制重新建立
   docker-compose up -d --force-recreate #這行為背景運作

7. 關閉的方法

   docker-compose down
   docker volume ls # 查看volume的使用
   docker volume rm volumeName # 刪除volume內容
