docker

Ubuntu docker azure

1 Try to stop docker but got error on Ubuntu,
docker rm $(docker ps -aq)

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock:
Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json?all=1": dial unix /var/run/docker.sock: connect: permission denied ```

solution:
just open terminal and type this command
sudo chmod 666 /var/run/docker.sock

2 Azure上的vm,把pem从一台电脑拷贝的另一台电脑就连不上（ssh -i timeout)了。

• 应该是vm上ubuntu默认的防火墙把端口关了，去zaure上，找到[Run command]-【RunShellScript],执行命令【sudo ufw allow 22]
