[Docker][Ubuntu] 在ubuntu設定docker engine透過http proxy連線

[Ubuntu 16.04]

此版已用systemd來管理服務，所以必須經由以下設定來走http proxy

1. sudo mkdir -p /etc/systemd/system/docker.service.d
2. sudo vim /etc/systemd/system/docker.service.d/http-proxy.conf
3. edit your http proxy config file

[Service]

Environment="HTTP_PROXY=http://proxy.example.com:80/" "NO_PROXY=localhost,127.0.0.1,docker-registry.somecorporation.com"

      4. sudo system daemon-reload
      5. sudo systemctl restart docker

[Ubuntu 14.04]

1. sudo vim /etc/default/docker # edit your docker runtime context file

DOCKER_OPTS="--log-opt max-size=500m --insecure-registry {docker-registry} --dns 8.8.8.8" 

export http_proxy="http://{http-proxy}:8080"

export https_proxy="https://{http-proxy}:8080"

export no_proxy="localhost,127.0.0.1"

      2. sudo service docker restart
