openconnect-proxy docker image

Packages an OpenConnect VPN client with an authenticating HTTP proxy to provide access to the VPN via the proxy.

Example usage:

# docker run --privileged -it -p 8123:8123 -v /tmp/oc.pw:/tmp/oc.pw -e OPENCONNECT_PASSWORD_FILE=/tmp/oc.pw -e OPENCONNECT_USERNAME=oc_user -e OPENCONNECT_GROUP=oc_group -e OPENCONNECT_HOST=vpn.example.com -e PROXY_USERNAME=puser -e PROXY_PASSWORD=secret matinrco/openconnect-proxy

Substitute the real values for your AnyConnect VPN credentials in place of oc_user, oc_group, and vpn.example.com; and create a file (in this case /tmp/oc.pw) containing the associated password.

While the above container is running, you should be able to use the docker host an http proxy to access resources via the VPN.

For example, you could set an http_proxy environment variable and use wget:

# export http_proxy=http://puser:[email protected]:8123/
# wget http://protectedhost.example.com/

Available environment variables :

PROXY_USERNAME
PROXY_PASSWORD

OPENCONNECT_PASSWORD
OPENCONNECT_PASSWORD_FILE
OPENCONNECT_USERNAME
OPENCONNECT_GROUP
OPENCONNECT_HOST
OPENCONNECT_NO_CERT_CHECK

Note

  • Proxy authentication is optional . if you don't want any authentication just don't pass username/password.
  • You need to provide openconnect password with just one method . In a file or fill the related env var.
  • If your openconnect server doesn't provide valid certificate , pass OPENCONNECT_NO_CERT_CHECK=true to ignore certificate check.
  • OPENCONNECT_GROUP is also optional.
