Private Internet Access
Private Internet Access docker container
What is Private Internet Access
Private Internet Access VPN Service encrypts your connection and provides you with an anonymous IP to protect your privacy.
How to use this image
This image provides the configuration file for each region managed by PIA.
The goal is to start this container first then run other container within the PIA VPN via
Starting the client
docker run --cap-add=NET_ADMIN --device=/dev/net/tun --name=pia -d \ --dns 18.104.22.168 --dns 22.214.171.124 \ -e 'REGION=US East' \ -e 'USERNAME=pia_username' \ -e 'PASSWORD=pia_password' \ colinhebert/pia-openvpn
Due to the nature of the VPN client, this container must be started with some additional privileges,
--device=/dev/net/tun make sure that the tunnel can be created from within the container.
Starting the container in privileged mode would also achieve this, but keeping the privileges to the minimum required is preferable.
Creating a container that uses PIA VPN
docker run --rm --net=container:pia \ tutum/curl \ curl -s ifconfig.co
The IP address returned after this execution should be different from the IP address you would get without specifying
Additional arguments for the openvpn client
Every parameter provided to the
docker run command is directly passed as an argument to the openvpn executable.
This will run the openvpn client with the
docker run ... --name=pia \ colinhebert/pia-openvpn \ --pull
Avoiding using environment variables for credentials
By default this image relies on the variables
PASSWORD to be set in order to successfully connect to the PIA VPN.
It is possible to use instead a pre-existing volume/file containing the credentials.
docker run ... --name=pia \ -e 'REGION=US East' \ -v 'auth.conf:auth.conf' \ colinhebert/pia-openvpn \ --auth-user-pass auth.conf
Connection between containers behind PIA
Any container started with
--net=container:... will use the same network stack as the underlying container, therefore they will share the same local IP address.
Prior to Docker 1.9
--link=pia:mycontainer was the recommended way to connect to a specific container.
Since Docker 1.9, it is recommended to use a non default network allowing containers to address each other by name.
Creation of a network
docker network create pia_network
This creates a network called
pia_network in which containers can address each other by name; the
/etc/hosts is updated automatically for each container added to the network.
Start the PIA container in the pia_network
docker run ... --net=pia_network --name=pia colinhebert/pia-openvpn
pia_network there is now a resolvable name
pia that points to that newly created container.
Create a container behind the PIA VPN
This step is the same as the earlier one
# Create an HTTP service that listens on port 80 docker run ... --net=container:pia --name=myservice myservice
This container is not addressable by name in
pia_network, but given that the network stack used by
myservice is the same as the
pia container, they have the same IP address and the service running in this container will be accessible at
Create a container that access the service
docker run ... --net=pia_network tutum/curl curl -s http://pia/
The container is started within the same network as
pia but is not behind the VPN.
It can access services started behind the VPN container such as the HTTP service provided by
