What is OpenConnect Server?

OpenConnect server (ocserv) is an SSL VPN server. It implements the OpenConnect SSL VPN protocol, and has also (currently experimental) compatibility with clients using the AnyConnect SSL VPN protocol.

How to use this image

Get the docker image by running the following commands:

docker pull tommylau/ocserv

Start an ocserv instance:

docker run --name ocserv --privileged -p 443:443 -p 443:443/udp -d tommylau/ocserv

This will start an instance with the a test user named test and password is also test.

Environment Variables

All the variables to this image is optional, which means you don't have to type in any environment variables, and you can have a OpenConnect Server out of the box! However, if you like to config the ocserv the way you like it, here's what you wanna know.

CA_CN, this is the common name used to generate the CA(Certificate Authority).

CA_ORG, this is the organization name used to generate the CA.

CA_DAYS, this is the expiration days used to generate the CA.

SRV_CN, this is the common name used to generate the server certification.

SRV_ORG, this is the organization name used to generate the server certification.

SRV_DAYS, this is the expiration days used to generate the server certification.

NO_TEST_USER, while this variable is set to not empty, the test user will not be created. You have to create your own user with password. The default value is to create test user with password test.

The default values of the above environment variables:

Variable Default
CA_CN VPN CA
CA_ORG Big Corp
CA_DAYS 9999
SRV_CN www.example.com
SRV_ORG My Company
SRV_DAYS 9999

Running examples

Start an instance out of the box with username test and password test

docker run --name ocserv --privileged -p 443:443 -p 443:443/udp -d tommylau/ocserv

Start an instance with server name my.test.com, My Test and 365 days

docker run --name ocserv --privileged -p 443:443 -p 443:443/udp -e SRV_CN=my.test.com -e SRV_ORG="My Test" -e SRV_DAYS=365 -d tommylau/ocserv

Start an instance with CA name My CA, My Corp and 3650 days

docker run --name ocserv --privileged -p 443:443 -p 443:443/udp -e CA_CN="My CA" -e CA_ORG="My Corp" -e CA_DAYS=3650 -d tommylau/ocserv

A totally customized instance with both CA and server certification

docker run --name ocserv --privileged -p 443:443 -p 443:443/udp -e CA_CN="My CA" -e CA_ORG="My Corp" -e CA_DAYS=3650 -e SRV_CN=my.test.com -e SRV_ORG="My Test" -e SRV_DAYS=365 -d tommylau/ocserv

Start an instance as above but without test user

docker run --name ocserv --privileged -p 443:443 -p 443:443/udp -e CA_CN="My CA" -e CA_ORG="My Corp" -e CA_DAYS=3650 -e SRV_CN=my.test.com -e SRV_ORG="My Test" -e SRV_DAYS=365 -e NO_TEST_USER=1 -v /some/path/to/ocpasswd:/etc/ocserv/ocpasswd -d tommylau/ocserv

WARNING: The ocserv requires the ocpasswd file to start, if NO_TEST_USER=1 is provided, there will be no ocpasswd created, which will stop the container immediately after start it. You must specific a ocpasswd file pointed to /etc/ocserv/ocpasswd by using the volume argument -v by docker as demonstrated above.

User operations

All the users opertaions happened while the container is running. If you used a different container name other than ocserv, then you have to change the container name accordingly.

Add user

If say, you want to create a user named tommy, type the following command

docker exec -ti ocserv ocpasswd -c /etc/ocserv/ocpasswd -g "Route,All" tommy
Enter password:
Re-enter password:

When prompt for password, type the password twice, then you will have the user with the password you want.

-g "Route,ALL" means add user tommy to group Route and group All

Delete user

Delete user is similar to add user, just add another argument -d to the command line

docker exec -ti ocserv ocpasswd -c /etc/ocserv/ocpasswd -d test

The above command will delete the default user test, if you start the instance without using environment variable NO_TEST_USER.

Change password

Change password is exactly the same command as add user, please refer to the command mentioned above.
