docker-ocserv is an OpenConnect VPN Server boxed in a Docker image built by Tommy Lau.
Update to version 0.11.8 and use Alpine 3.6 as base image
You can login with two group (Route/ALL) from now on.
Route group means you can access China Mainland website directly and other connection will be protected by OpenConnect VPN
All group means all of connection will be protected by OpenConnect VPN
Thanks for @sempr's contribution and suggestion, from now on, the Alpine Linux will be used as the base image. The docker image size has been dramatically reduced from around 150MB to only 20MB.
NOTICE: You have to use Docker version 1.9.0 or later to support Alpine, DO NOT UPDATE the image if your Docker version is older than 1.9.0
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.
Get the docker image by running the following commands:
docker pull tommylau/ocservStart an ocserv instance:
docker run --name ocserv --privileged -p 443:443 -p 443:443/udp -d tommylau/ocservThis will start an instance with the a test user named test and password is also test.
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 |
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/ocservStart 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/ocservStart 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/ocservA 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/ocservStart 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/ocservWARNING: 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.
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.
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 usertommyto groupRouteand groupAll
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 testThe above command will delete the default user test, if you start the instance without using environment variable NO_TEST_USER.
Change password is exactly the same command as add user, please refer to the command mentioned above.
