Docker Ubuntu Behind Proxy

Question

Looking at docs there is no instruction on how to run it behind a proxy. https://docs.docker.com/installation/ubuntulinux/

Reading on forums, the instruction is to update /etc/default/docker to export the proxy setup.

 export http_proxy="http://127.0.0.1:3128/"  export https_proxy="http://127.0.0.1:3128/"  export HTTP_PROXY="http://127.0.0.1:3128/"  export HTTPS_PROXY="http://127.0.0.1:3128/" 

Then we restart/start docker

 sudo service docker start 

Inside a container, if I run 'apt-get', npm install, bower install I cant get through the proxy.

Not sure what I m missing.

Ubuntu 14.04 LTS

For Ubuntu 14.04 LTS who uses SysVinit, you should modify /etc/default/docker file:

# cat /etc/default/docker # Docker Upstart and SysVinit configuration file  # # THIS FILE DOES NOT APPLY TO SYSTEMD # #   Please see the documentation for "systemd drop-ins": #   https://docs.docker.com/engine/articles/systemd/ #  ....... # If you need Docker to use an HTTP proxy, it can also be specified here. export http_proxy="http://web-proxy.corp.xxxxxx.com:8080/" export https_proxy="https://web-proxy.corp.xxxxxx.com:8080/" ...... 

Then restart docker:

service docker restart 

Ubuntu 16.04 LTS / Ubuntu 18.04 LTS

For Ubuntu 16.04 LTS who uses Systemd, you can follow this post:

(1) Create a systemd drop-in directory:

mkdir /etc/systemd/system/docker.service.d 

(2) Add proxy in /etc/systemd/system/docker.service.d/http-proxy.conf file:

# cat /etc/systemd/system/docker.service.d/http-proxy.conf [Service] Environment="HTTP_PROXY=https://web-proxy.corp.xxxxxx.com:8080/" Environment="HTTPS_PROXY=https://web-proxy.corp.xxxxxx.com:8080/" Environment="NO_PROXY=localhost,127.0.0.1,localaddress,.localdomain.com" 

(3) Flush changes:

systemctl daemon-reload 

(4) Restart Docker:

systemctl restart docker

Edit you /etc/default/docker file

sudo vim /etc/default/docker 

Add this line at the bottom:

export http_proxy="http://PROXY_IP:PROXY_PORT"
