StrongSwan as a Docker container

Latest image based on alpine, please use alpine branch for it.

IPSec XAUTH ikev1 VPN server

Just build it or pull it from andrey0001/strongswan and run it something like this:

docker run -t -d --privileged \
-e VPN_USER=user \
-e VPN_PASS=password \
-e VPN_PSK=secretkey \
-e VPN_SUBNET=192.168.14.0/24 \
--publish 4500:4500/udp \
--publish 500:500/udp \
--hostname strongswan \
--name strongswan andrey0001/strongswan

• VPN_USER = username (default:user1)
• VPN_PASS = password (default:Sup3rS3cr3t)
• VPN_PSK = preshared key (default:s3cr3tk3y)
• VPN_SUBNET = network (default:192.168.95.0/24)

You could add additional users to the file /etc/strongswan/ipsec.secrets , then reload secrets by:

strongswan rereadsecrets

inside the container.

Also, you could use volume (bind mount a volume) for configuration files of strongswan (to store it on host):

-v /etc/strongswan:/etc/strongswan 

and reread secrets from host:

docker exec -it strongswan /usr/sbin/strongswan rereadsecrets

and reread configuration

docker exec -it strongswan /usr/sbin/strongswan update
