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.
