MAC安裝Docker Desktop

MAC上安裝Docker Desktop能夠網站下載安裝，也能夠經過brew安裝。這裏記錄brew安裝的命令：

brew cask install docker

安裝完成後，建立Dockerfile

FROM nginx RUN echo 'Hello this is mywebsite' > /usr/share/nginx/html/index.html

開啓Goolge Cloud Container Registy權限：

gcloud auth configure-docker

建立Dockerfile：

from flask import Flask from datetime import datetime import socket app = Flask(__name__) @app.route("/") def hello(): now = datetime.now() html1 = str(socket.gethostname()) html2 = now.strftime("%m/%d/%Y, %H:%M:%S") html = "<h1>Time: " + html2 + "\n" + "Hostname is: " + html1 + "</h1>\n"
    return html if __name__ == "__main__": app.run(host='0.0.0.0', port=80)

安裝列表requirements.txt：

Flask

程序代碼app.py:

from flask import Flask import socket app = Flask(__name__) @app.route("/") def hello(): html = socket.gethostname() return html if __name__ == "__main__": app.run(host='0.0.0.0', port=80)

Build Docker Image並上傳:

docker build ./ -t gcr.io/central-segment-217003/web-hostname:1.0 docker push gcr.io/central-segment-217003/web-hostname:1.0

用此docker image建立docker：

docker run -d -p 127.0.0.1:80:80 gcr.io/central-segment-217003/web-hostname:1.0 $ curl localhost 423fcf67c506

查看docker狀況：

$docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 423fcf67c506 gcr.io/central-segment-217003/web-hostname:1.0   "python app.py"     41 seconds ago      Up 39 seconds       127.0.0.1:80->80/tcp   sweet_napier

和顯示的hostname相同。
